Abstract
SARS Corona Virus 2 has imparted its impact on each region of existence globally via COVID-19. Lockdown related to COVID-19 made the scenario worse mainly in growing nations like India. It imparted its impact on transportation, supply chains, manufacturing and export of seafood mainly shrimp and prawn and in India especially in coastal states like Kerala fisheries is one of the primary sources of income. Kuttanad in Alappuzha district of Kerala state, India is a geographically special place that lies beneath sea degree and farmers’ right here exercise bio saline farming. A survey was performed amongst allied workers of fisheries in the shrimp and prawn enterprise of Kuttanad to consider the impact of COVID-19 associated lockdown on the economy, livelihood activities, job, health repute and health care. Henry Garrett analyses projected extreme constraints in availability and distribution of prawn and shrimp, seedlings distribution, disruption in transportation, farming, processing, demand disruption, loss of employment and wages for the workers. To minimize and overcome the impact of a pandemic the Kerala state government introduced various schemes of which many respondents of the survey opinioned that the sole supply of income as cash, was once the aid obtained from welfare pension and relief fund. All registered shrimp and prawn processing enterprise employees had been supplied with relief funds. The eligible worker’s social welfare pension increased and the Kerala state Government ensured the regular disbursal of pension. The four-month welfare pension is dispensed as a lump sum in April 2020. Workers additionally opinioned that the sole supply of livelihood was free or subsidized food grain (government ration) furnished by Kerala government authorities and some of them obtained meals packets from the owners of the shrimp and prawn enterprises. All workers are properly conscious of the ‘Break the chain’ campaign of the Government of Kerala. Many short-term policies and schemes had been introduced for the people to tide over the scenario of COVID-19.

Abstract
Agriculture sector has developed with the influence of science and technology but it is not yet accepted by women as the main labour. According to the Census of India, a worker is defined as a person whose main activity is participation in any economically productive activity of a physical or mental nature. The work involved is not only the actual work, but also the effective supervision and direction of the work. It also includes unpaid work on the farm or in the family enterprise. It is very important to understand the nature of rural landscape changes during the urbanization process to prepare rural management plans for sustainable development. Although there is not much information available about how rural landscapes change and there is limited evidence of how they can be improved. With the change of time the landscape of agriculture has also changed completely but one thing which has not changed over the centuries is the concept of women as the dominant force in the field. Agriculture in developing countries like India absorbs and employs two-thirds of the female work force but fails to recognize them as employed labour. Female labour force in developing countries still faces oppressive conditions. Women are the modern builders of the destiny of any nation. Women are considered to be the backbone of the Indian rural landscape. Women are more active in rural India than in urban India. Most of the women do various types of work to fulfil their livelihood and agriculture is considered to be the largest unorganized sector in which a large number of rural women actively contribute. Rural women constitute the most important productive work force in the Indian economy. Almost all rural women in India can be considered farmers as most of them are directly and indirectly engaged in agriculture and allied activities. In spite of their above participation in any work in India and work on such a large scale, women are not yet actively involved in the mainstream of development and there is hardly any appreciation and recognition for their massive contribution. Most of the studies related to female labour in India were done in the early decades of Green Revolution, although there are some recent studies related to the participation of women in agricultural work in India. The present study relates to western Uttar Pradesh, the most agriculturally developed region of India's most populous state Uttar Pradesh producing labour intensive crops such as sugarcane, wheat and paddy. The study is based on an in-depth field survey and primary data of 160 agricultural households belonging to western UP, which throws fair light on the contribution of women in agriculture in the study area.

Abstract
Biosynthesis of nanoparticles using the extract of medicinal plant in a non- hazardous mode has gained wide attention for various application in Nano medicine. The biologicals method of metal nanoparticles synthesis is more effective because of slow reduction rate of polydispersity of the final product. In our, study we have synthesized silver nanoparticles using leaves extract of Withania somnifera leaf extract. The synthesized AgNO3 were found to have a size of 346±03nm and hydrodynamic diameter as determined by DLS. AgNO3 was stable in disc diffusion medium with zeta potential of -23±01mV. The antibacterial studies showed significant activity as compared to their respective standard. From the results, Withania Somnifera Silver nanoparticles has attained the maximum antimicrobial against clinical pathogen and also very good stability of nanoparticles throughput processing. As we concluded, this type of naturally synthesized silver nanoparticles could be a better green resolution in medicinal chemistry. Silver nanoparticles were prepared by green method. The reduction of metal ions by leaf extract loading Ag Nano composites of quite distinct proportions. The synthesized AgNP were characterized by UV- Visible Spectrophotometer, DLS (Dynamic light scattering). Based on the current conclusion, it is accomplished that silver nanoparticles could be used as an antifungal agent in controlling the disease caused by fungi. The present study has opened up the possible way for synthesizing multidrug resistance antimicrobial AgNPs using natural biomolecules which could be employed in the pharmacy industry. By using such plant extract to develop Nano medicine along idea variety of human other veterinary pathogens.

Abstract
The family Brassicaceae (Crucifers) including a number of vegetables grouped as Cole crops, root crops, herbaceous vegetables, oleiferous (oilseed) crops, and also ornamental plants, were observed to be infected by six species of Alternaria, causing leaf spots and blight, lesions on stems, petioles, silique; blossom blight, seedling blight, and damping off. Alternaria brassicae, the representative species of Brassicaceae was found to infect plants of all the groups of Crucifers followed by A. raphani restricted to eight hosts, A. brassicicola to five, A. japonica to four and A. alternata to only broccoli and radish. A. cheiranthi appeared to be a single species of Alternaria confined only to wallflower (Cheiranthus cheiri) to cause the leaf spot disease. Symptoms of all the groups of Brassicaceous hosts due to Alternaria species, the most distinguishing morphological features of the causative fungus have been described. The differences in symptomatology and etiology of diseases have been critically analyzed. A very simple and feasible key has also been framed for the correct and easy identification of all the six species of Alternaria associated with brassicaceous vegetables, oleiferous and ornamental plants.

Abstract
Sclerotinia sclerotiorum is recognized as the most deleterious polyphagous plant pathogen with worldwide distribution. The pathogen is reported to causes disease over 500 plant species belong to diverse group of plants. The symptoms produced by this pathogen can develop at all the above-ground parts of the plant i.e., stems, leaves and pods during the pre-maturity or at the post-harvest stage, thereby, resulted in causing severe losses in both quantity and quality of the crop. The yield losses due to this pathogen varied from 0-100 percent which is dependent on the severity of the disease and the plant parts affected severely. Several nutritional and non-nutritional factors such as temperature, moisture, photoperiod, nutrients, pH, oxygen concentration, type soil, depth and mechanical factors affected the growth and reproduction of the pathogen. Therefore, the present study was conducted to ascertain the effect of different pH levels i.e., 3.5 to 8.5 on growth and sclerotial development of this pathogen. The observations thus clearly ascertain that the growth and sclerotial production of S. sclerotiorum was significantly influenced by different pH levels, but fungus preferred pH 4.5 to 6.0 for their maximum radial growth and sclerotial development.

Abstract
Alginic acid is a non-agricultural, non-synthetic substance as allowed as an ingredient or on processed products labelled as “organic” or made with organic. Alginic acid is derived from brown seaweeds and is extracted primarily through different treatments. Gelatin is a nutritious protein that finds applications as an ingredient in the food, pharmaceutical and photographic industries. Gelatin derived from pig skin is normally referred to as type-A gelatin and gelatin derived from beef skin is referred to as type-B gelatine. Sodium alginate is a cell wall component of marine brown algae and contains approximately 30-60% alginic acid. The conversion of alginic acid to sodium alginate allows its solubility in water, which assists its extraction. The polymers closely resemble alginic acid, a seaweed polysaccharide as shown by composition and alginate digestion. Thickening property of various agents like gelatine alginate and natural colloidal agents (G. edulis) were checked Synthetic (purified) agents enhances the thickening property faster than natural one. Time variation observed from 2-12minutes for natural agent (G. edulis) and 5-20 minutes for synthetic and purified chemical agents. Food thickening agents are widely used to modify rheological and textural properties as well as to enhance the quality attributes. Improvement in moisture bunding capacity, structural modification and altering flow behaviour properties are the major functions of food thickeners. Factors such as temperature shear. pH ionic strength etc. have effect on the functionally of these thickening agents and must be carefully optimized by food processor while formulation. The manufactures use various thickeners in the form of starch gum. Xanthum gum, gum Arabic guar gum, and carboxyl methyl cellulose to improve the consistency of food.

Abstract
Black rice is widely popular variant of rice (Oryza sativa L.) widely consumed in India and the South Asian countries. The distinctive colour in black rice is due to the presence of anthocyanins in its bran which endows it a distinctive place in desserts. Its distinctive colour and the nutty texture make it popular as a snack and as a natural food colourant. The present study attempts to explore Advanced Fuzzy logic approach for optimized sensory evaluation of porridge vis-à-vis substitute to the popular white rice porridge, given the higher nutritional benefits of black rice. A sensory study to explore the preferred porridge with its composition was conducted with 28 samples to determine the suitable ratio of constituents in black rice porridge. The study revealed that a ratio of 60 grams of dry black rice by weight in a liter of milk is most preferred over the popular white rice counterpart. The results can serve as guidance to prospective entrepreneurs, restaurants to devise the most suitable composition of constituents for black rice porridge and for targeting the health-conscious consumers.

Abstract
The present study was undertaken to analyze groundnut market integration in six major regional markets located in Gujarat (Junagadh and Rajkot), Rajasthan (Bikaner and Jaipur) and Karnataka (Hubballi and Raichur) states of India were selected based on major arrivals of commodity to respective market, using monthly wholesale prices of groundnut during 2005 to 2021. Augmented Dickey-Fuller Unit root test indicated that the price series in each location are non -stationary at their levels, and stationary at their first differences. Co-integration results showed that the regional markets have price linkages and thus are spatially integrated. Johansen’s multiple co-integration tests reveals that that their existence of at least five co-integration equations for selected groundnut markets based on likelihood-ratio test. Granger causality test explain that, there is existence of mostly bidirectional causality with few unidirectional causality among selected groundnut markets. The unidirectional relationship was found for the pair of Raichur market indicates that price of Raichur market influence the price of Rajkot and Hubballi market. Similarly, Hubballi, Junagadh, Rajkot, Bikaner and Jaipur exerted bidirectional causality among them. Thus, results of the study indicated a strong integration among major groundnut markets in India. It’s clearly manifest that Raichur is the independent market for groundnut prices in south India and also there bidirectional relationships exist among the domestic markets, So it is confirmed that the price of one market influence the price of other markets. The test for causality is based on F statistics. Which indicated the price transmission happening in long run adjustments and the presence of short run equilibrium existed among the groundnut markets in India. Vector error correction estimates indicates that, extent of groundnut markets integration for different lags in the current study.

Abstract
Suaeda maritima (L.) Dumort., a halophyte herb of the family Chenopodiaceae, grows gregariously along the coastal belt of Purba Medinipur district of West Bengal in India. The geographical location of this area is in between 21°63'16''N to 21°70'50''N latitude and 87°54'63''E to 88°12'40''E longitude. This annual salt marsh species is regularly used by the local people as food and also for curing many a disease. Earlier works report on phenotypic plasticity of it and other aspects of morpho-anatomical features as well as useful phytochemical elements of it. Since the populations of this species in this coast are not growing contiguously, in search of any plasticity due to genetic difference amongst the individuals of different populations AFLP analyses were carried out. The studied area was transected into eight zones. The genetic distances were calculated based on the AFLP bands that had been amplified using the 12 primer combinations. The similarity indices (SI) ranged from 0.19 to 0.83. The dendrogram was created using the UPGMA and the genotypes were found to be classified into 2 major groups. This study revealed the existence of genetic diversity even among the individuals of closely growing populations of this species, indicating significant dynamism in it, a fact which may be quite imperative of its ability to cope up with the fragile physical environment it grows in.

Abstract
From the last decade, awareness on usage of plant growth promoting rhizobacteria (PGPR) is increasing on a rapid scale. Though several advantages of PGPR were noticed, several disadvantage of individual microbial inoculants viz. inconsistency, poor performance in various geographical locations were noticed. The present research aims in developing a cost effective PGPR consortia-based formulation with high stability. The formulation developed showed high stability at 37 oC (2.6 × 108/ml), 45 oC (9.1 × 107/ml) and 4 oC (6.7 × 108/ml). Shelf-life comparison study with the market product and unformulated microbial cells showed high stability in the developed encapsulated liquid formulation (1.3 × 108/ml). Based on the results, it can be concluded that the developed formulation can be effectively used for the formulation of PGPR consortium. The present research work targets, cost effective plant growth promoting consortium-based formulation with better shelf life. Based on the above results, it can be concluded that the developed encapsulated liquid formulation showed high stability when compared to the market product and the unformulated microbial cells. So, the developed formulation can be effectively used for the formulation of plant growth promoting microbial consortium.

Abstract
Heavy metal pollution of agricultural soils is a widespread environmental threat. Heavy metals induce deleterious effects on plants. These effects can be minimized by the application of PGPB on plants under stress. The main objective of this study is to assess the effect of PGPB inoculants of Brevundimonas sp. of bacterium on growth and antioxidant enzyme activities of pigeon pea seedlings grown under high mercury concentrations. The plant antioxidant response has been analyzed by quantifying the catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), and glutathione reductase (GR) enzyme activity in pigeon pea seedlings exposed to mercury and different PGPB treatments. Our data indicated that the bacteria acted as a shield and protect the Cajanus plants from mercury toxicity and hence extent of lipid peroxidation and antioxidant enzymes (CAT, POX and SOD) were determined for all three treatments i.e., control (C), untreated (mercury exposed) and treated (bacteria + mercury). The antioxidant enzyme activities, MDA content and proline content were increased in the mercury exposed pigeon pea and a parallel reduction was observed in Brevundimonas bacterium treated pigeon pea seedlings under mercury stress indicate that these plants faced less stress in presence of Brevundimonas bacterium.

Abstract
Maize (Zea mays L.) is one of the most important cereal crop plants. It can be used in cooked, roasted, fried ground, crushed to prepare various food items like Kurkure, Popcorn, Corn syrup, Corn sauce, Cornmeal as well as it also useful as medicines and as raw materials for industries. Due to Climatic changes, it has been reported as a driver for emerging food and feed safety. This toxic infection result reduces grain quality due to contamination of maize seeds with the mycotoxin especially aflatoxin. One of the most effective ways to control the problems caused by aflatoxins due to prevent the growth of seed germination. Bitter plants like Azadirachta indica is one of the medicinal plants having antifungal or antimicrobial properties. Our findings reveals that the maximum inhibition in seed germination were 76.56 % on maize at 2ppm concentration of AFT- B1. Also reports shows that, the minimum inhibitions in seed germination were recorded in chl a, chl b, Total chl a+b and carotenoids were 9.75, 22.22, 9.83 and 47.51 in maize seedlings due to treatment of AFT- B1 with A. indica at 2 mg/ml concentration. Ultimately Azadirachta indica extracts reduce the inhibitory properties of AFT-B1 produced by A. flavus. Furthermore, the bitter plant like A. indica investigated in the present study may provide potential leads for novel bioactive. This will ultimately lead to substantial, financial returns to the farmers as these Bitter plant like Azadirachta indica.

Abstract
Guava is a most important fruit crop and it has higher adaptability as well as productivity. Even though, Guava cultivation was introduced in the seventeen centuries, the farmers were unaware of the improved cultivation practices. Hence an attempt was made in this study, to analyze cost and returns of guava cultivation in Villupuram district of Tamil Nadu at farm level with the following objectives: i) To estimate cost and returns in Guava production in the study area, ii) To give policy suggestions based on the results of the study. The present study was conducted in Thiruvennainallur block of Villupuram district. Further, in block, four villages were selected for the study and finally, 120 growers randomly selected. In this study, CCPC Method of Cost of Cultivation and Benefit-Cost Ratio was worked out to analyze the profitability in guava cultivation. The results indicated that the per unit cost of cultivation is declining as size group increases, since it is a perennial crop, one has to wait for five years for first yielding of Guava. This problem could be better managed by cultivating intercrops in guava plantations.

Abstract
The Government of India has launched the Pradhan Mantri Fasal Bima Yojana, a crop insurance scheme that subsidizes the premium and promises to settle claims timely. Tripura is a state where 65 to 70 per cent of people earn their livelihood from the agricultural sector. The present paper tries to determine the extent of crop insurance coverage in the state under the Pradhan Mantri Fasal Bima Yojana, and also examines the determinants of crop insurance demand, highlighting the effect of climate change. The study is largely based on primary data collected through cluster random sampling techniques. Standard statistical tools are used to analyze the primary data. Moreover, a binary logistic regression has also been carried out to examine the determinants of crop insurance demand in Tripura. The study finds that only 24 per cent of the farmers are willing to take crop insurance. The results also show that farm income, coverage period wanted, climate change and risk perception are significant factors associated with crop insurance.

Abstract
Linseed (Linum usitatissimum Linn.) is cultivated as cash crop by farmers in various regions of Maharashtra. Increased vigor and production of crop was naturally achieved through cross pollination by various foragers during blooming season. One of the major problems of crop health during the growth period is attacks of various pests. Farmers applied various insecticides to control pest attack, but on the other hand insecticides have adverse effect on foragers of particular crop. The present study attempted to assess insecticidal effect on foragers of linseed with respect to various pollinating attributes. In this field investigation, sowing of NL-97 variety seeds of linseed was carried out in two different farmlands, one with insecticides sprayed and another without insecticide application. Various attribute of pollination service was observed during this research on both crop fields alternately in highest blooming period. Observational data of pollinating attribute for each forager between both plots used to calculate percent difference. Results of the study revealed that abundance, foraging rate and foraging duration of foragers was significantly affected by insecticide application (p<0.05). A. cerena indica, Halictus spp., Trigona spp. and Coccinella septempunctata found as pollens of linseed attached on their body and considered as pollinators of particular crop. Foragers on bloom of treated field was observed after 36 (± 4) hour of insecticide application.

Abstract
Water is the most important substance required for life on the earth. But today good quality water has become a scarce commodity. The poor quality of water affects human health. Thus, it is an urgent need to monitor the water quality regularly. The variety of microbial populations and activities of these microbes are influenced by the chemical, physical and biological characteristics of particular water as well as the presence of growing aquatic plants. Microorganisms are always present in water which may be pathogenic or non – pathogenic. Pathogenic forms include various species of bacteria, viruses, fungi and protozoans. Further, the interaction of water and microorganisms help in the biochemical purification of wastewater in silt places and in biological ponds. Hence the present investigation was carried out to determine Fungal diversity in a freshwater lake located in Perungudi, Chennai, Tamil Nadu, India. Freshwater samples for the study were collected from two different sites of Perungudi Lake, Tamil Nadu, India for 1 year from January 2019 to November 2019 with an interval of 1 month. The water samples were examined for Total fungal count and Identification of fungal species. In Perungudi Site 1 the total count of fungi was high as 11.7 × 102 CFU/ml during January 2019 and less than 0.33 × 102 CFU/ml in July, September and November 2019 in site 2 during the period of study. This variation in fungal count in site 1 of the Perungudi lake is due to the environmental and climatic conditions of the lake site which may affect the zooplankton and Phytoplankton of the freshwater.

Abstract
Pomegranate is a unique crop due to its drought tolerance capacity and pharmaceutical and nutraceutical values. It has special economic importance among fruit crop of arid and semi-arid regions. Area under pomegranate has been growing in India. In the Indian tropics pomegranate crop is severely affected by bacterial blight and several other fungal and bacterial diseases. Disease free new plantation can be established only if high quality planting material is available. Tissue culture offers the possibility of propagating disease-free pomegranate plantlets but success rate of transplanting in vitro plants to field is a challenge. Light, temperature, humidity and growing media play an important role in the acclimatization process. An effort was made to standardize a commercial secondary acclimatization process for in vitro propagated pomegranate plants. The secondary acclimatization experiments involved light conditions and growing substrates which help in controlling growing environment especially light, temperature and water relations. In this study, pomegranate plants subjected to three light cut off treatments (30%, 45% and 70%) in combination with four different growing substrates (M1, M2, M3 and M4). Treatment receiving average 282.72 micro mole /m2/sec natural light (21.81% total light) and growing substrate with a mixture of peat and cocopeat gave better plant growth and success in acclimatization.

Abstract
Forests are vital resources for the survival of many ethnic communities in any part of the world. The present study reported the utilization of 18 parts of 105 wild edible plant species (WEPs) by the tribes of Srikakulam district, Andhra Pradesh, India viz., Jatapu, Kapu Savara, Konda Savara and Gadaba etc., belonging to 49 families. Savaras and Gadabas are considered as Particularly Vulnerable Tribal Groups (P.V.T.G). Analysis of plant life forms revealed that tree species are represented with the highest percentage i.e., 43% followed by climbers and herbs with 22%, shrubs with 12% and thallus with 1%. Analysis of eaten state by tribals showed the dominance of 60 plant species (53%) eaten in raw state, 47(41%) species as cooked, 3 (3%) species in roasted state, 2 (3%) species eaten soaked and each (1%) in boiled and burnt form. Although these wild edible plants play an important role in food security, they are ignored. These are popularized by introducing them into home gardens, agricultural fields of farmers in plain areas and by establishing Wild edible plant species parks by the Government of India.

Abstract
An important component in an aquatic system is plankton which serve as a key group for energy production their growth, abundance and diversity reflect on the density and diversity of other systems organisms in that system. Hence the present study was attempted to analyze the density and diversity of plankters living in a fresh water temporary lentic system located in Kulumani Village, Tiruchirappalli District of Tamil Nadu, India. A total of 44 plankters (25 Phytoplankton and 19 Zooplankton) could be Identified. The phytoplankton belonged to 4 groups and zooplankton to 5 groups. Each group appeared to prefer a certain period of time to recorded their highest group count. Highest diversity was recorded in the hotter periods. This is probably attributed to favorable climatic, physico-chemical variables and nutrient loading.

Abstract
Nanocrystalline Ni particles were synthesized by chemical reduction and coated with silica layer by a modified Stöber process. X-ray diffraction patterns of the samples showed an average size of 18 nm for the Ni nanocrystals. The coated particles exhibited improved thermal stability. The magnetic hysteresis established the ferromagnetic behaviour and an increased coercivity for the nanocomposite. The impedance measurement showed activation energy of 1.3 eV and decrease in dc conductivity with temperature. The high dielectric constant over a wide frequency range is explained as a consequence of concentration of Ni much higher than the percolation threshold. The conductivity mechanism is dominated by tunneling at low frequency and electron hopping at high frequencies. The material suffers a low loss in high frequency range, making it suitable for high frequency magnetic applications.

Abstract
Present investigation deals with the flowering phenology, pollen production, flower visitor interaction, pollen dispersal and pollination of a highly economic important crop plant Abelmoschus esculentus (L.) Moench. belonging to the family Malvaceae. Flowering occurred in between April - October, which are yellowish, actinomorphic flowers open in morning (05:00am to 06:30am) and anther dehiscence takes place transversely after flower opening. In average a single anther produces 1250 pollen grains. After flower opening large number of insects come in contact with flower like member of Hymenoptera (Ant, Apis cerana indica, Pithitis sp.), Lepidoptera (Borbo sp.) and member of Diptera. The style is surrounded by a staminal column which bears large number of anthers. The pollen grains come in contact with the stigmas around the throat of the staminal column. It has been found experimentally that there is significant difference in fruit set under open-pollinated (75%) and bagging (45%). Bagging result indicates the self-pollination and open-pollinated fruit set shows insects are helpful for cross-pollination and fertilization because the flowers are very attractive to the flower visitors.

Abstract
The adsorption process by silver nanoparticles has been investigated an effective agent for removing selective heavy metals from the industrial wastewater. In this study, silver nanoparticles were synthesized in the presence of Aerva lanata leaf extract as adsorbent for copper and Zinc ions removal from industrial waste water solution. silver nanoparticles prepared by co-precipitation method and Aerva lanata leaf extract was used to prevent accumulation and reduce the diameter of the particles. Silver nanoparticles were characterized by Scanning Electron microscope (SEM), Transmission electron microscopy (TEM). Effect of various parameters such as contact time, pH, metal concentration and adsorbent dosage was determined on the removal efficiency by using atomic absorption spectrophotometer. Based on the present investigation, it could be concluded that some low-cost materials like Aerva lanata silver nanoparticles can be used efficiently in the removal of Heavy metal ions (Cu2+ and Zn2+) from effluent. The removal of heavy metal ion was pH dependent as the adsorption capacity increases with increasing the pH value of the solution, and at a particular pH the order of increasing the removal percentage was Zn2 ˂ Cu2+. Experimental results showed that the best pH was 4 and time was 90 min. The metal ions showed different behaviors towards on Aerva lanata silver nanoparticles by increasing the initial concentration of the metal ions. The copper and zinc ions are usually soluble in acidic pH and the maximum removal of cadmium by green synthesis silver nanoparticles was obtained in the pH of 4, so these nanoparticles can be a good adsorbent for the removal of heavy metal removal from wastewater.

Abstract
Lanthanum doped with copper oxide nanoparticles with size ranging from 20 to 100 nm and 10 µm length were prepared by reacting copper nitrate with Lanthanum oxide. The structure of the nanoparticles was confirmed by scanning electron microscope (SEM) analysis. Photocatalytic activity of the insecticides imidacloprid and bifenthrin was investigated. The decontamination effect of catalyst on the residues of imidacloprid and bifenthrin in water was evaluated in three different buffer solutions (pH 4.0, 7.0 and 9.0). The catalytic reaction was measured under direct sunlight at two different concentration levels of Imidacloprid and Bifenthrin. The optimum concentration of catalyst (lanthanum doped copper-oxide) required for the decontamination was found to be 0.05 g/L. Residues were quantified by ultra-fast High-Performance liquid chromatography method (UHPLC-PDA). Parameters, DT50 and DT90 were calculated from the dissipation data. The rate of the reaction showed first order kinetics in water. The addition of Lanthanum doped with copper oxide nanoparticles contributed to significant photocatalytic dissipation of residues. Complete mineralization of the residues was confirmed by the ultra-fast high-performance liquid chromatography. The method has the limit of quantification 0.01 mg/L in water.

Abstract
The accumulation of free radicals in the body leads to many diseases due to oxidative stress. Numerous studies are currently being conducted to prevent oxidative stress and neutralize the effects of free radicals by antioxidants primarily of plant origin rather than synthetic ones. Hygrophila auriculata belonging to the family Acanthaceae was used in this study to assess the phytochemical constituents, free radical scavenging ability, and the amount of enzymatic and non-enzymatic antioxidants. Four solvents, namely ethanol, ethyl acetate, chloroform, and water, were taken to extract Hygrophila auriculata root. Preliminary phytochemical analysis was carried out by adopting the standard protocol. Further, the free radical scavenging activity was assessed against two radicals, DPPH and FRAP, along with the reducing power ability. The enzymatic antioxidants include superoxide dismutase, catalase, peroxidase, polyphenol oxidase, glutathione-S-transferase, and non-enzymatic antioxidants such as ascorbic acid, α-tocopherol, and total phenols were assessed. The phytochemical screening revealed the presence of compounds such as alkaloids, flavonoids, sterols, phenols, saponins, tannins, proteins, carbohydrates, cardiac glycosides, and terpenoids firmly in the ethanol extract compared to all other solvents. The free radical scavenging activity showed a maximum scavenging power in the ethanol extract. The scavenging efficacy of DPPH and ABTS was 89.53 and 85.71%, respectively, at 100 μg/ml. Similarly, the reducing power was highest at the dose of 100 μg/ml. The ethanol extract possesses enzymatic antioxidants such as superoxide dismutase (111.3 ± 3.21 Units/mg), peroxidase (0.34 ± 2.11 Units/mg), catalase (4.53 ± 0.9 Units/mg), polyphenol oxidase (0.4 ± 0.01 μg/g), glutathione-S-transferase (2.3 ± 0.5 μg/g) and non-enzymatic antioxidants such as flavonoids (243.40 ± 1.23 mg/g), α – tocopherol (32.3 ± 0.18 μg/g), vitamin – C (2.93 ± 0.02). Thus, our findings suggest that roots of Hygrophila auriculata have the potential to scavenge the free radicals and prevent oxidative stress-related diseases, which pave the way for the plant to serve as a good phytotherapeutic agent against many diseases and disorders.

Abstract
The biotic component of an aquatic ecosystem is strongly related to diversity, abundance and seasonality of zooplankton. They play an important role in an aquatic food chain as they are consumed by most fishes and other organisms. Hence the present study was aimed at analyzing the zooplankton community structure during the different season of a year in a fresh water system at Ayilapettai, Tiruchirappalli District in Tamil Nadu, India. A total of 26 zooplankters would be identified belonging to four groups. Of these four groups, Rotifer dominated (15 species) followed by Copepoda and Cladocera (4 species each) and Ostracoda (3 species). Of the three seasons, the highest group count was recorded in the summer season. Individually, rotifers, cladocerans and copepods recorded highest counts during the summer season. While ostracods recorded their highest counts during the winter/rainy season. The abundance and diversity appeared to increase with diversity values. The growth and composition of zooplankton were defendant on physic chemical variables, nutrients and local environmental conditions.

Abstract
Industrialization and urbanization have intensified the pollution of soil and aquatic ecosystems with multiple heavy metals and co-contaminants, including antibiotics. Microbes in such stressful environments develop unique strategies to survive in such stressful environments and evolve with resistance to multiple metals. Using these organisms to bioremediate multiple metals simultaneously will be a sustainable and cost-effective approach. The present study investigated the bioremediation capabilities of multiple metal-resistant bacteria from sediments at Mahim Creek. A mucoid colony forming bacteria resistant to Cd, Cr and Pb was selected and characterized morphologically and biochemically. Molecular identification through 16srRNA sequencing revealed the organism to be Kosakonia radicincitans. MIC (minimum inhibitory concentration) of the organism was found to be 70 ppm for Cr, 100 ppm for Cd and 800 ppm for Pb. Study of the growth pattern of the bacteria was carried out in the presence and absence of the heavy metals. Its bioremediation capability was explored using Atomic Absorption Spectroscopic analysis and was found to have higher reduction efficiency for Cr and Pb than Cd. The organism also exhibited resistance to multiple antibiotics and showed an MAR (Multiple Antibiotic Resistance) index of 0.685.

Abstract
Onion (Allium cepa) which is considered to be a major vegetable in daily consumption of human being. Onion is grown across the globe and India stands in the second position in production. The paper attempts to examine the growth in area, production and productivity of onion crop in Karnataka state and also highlights on prices prevailing in the wholesale market and retail market of Kalabuargi city. It was evidenced there was a negative growth rate in productivity during the study period due to major pest incidence among the crop with rot disease and leaf blight infection. The producer share in consumer rupee was an average of 60 per cent indicating that left over is retained by various stake holders which includes the marketing cess and marketing costs associated with onion marketing. The government need to intervene and create awareness among the farmers about new high yielding, disease resistant variaties as well as importance of direct marketing through various channels.

Abstract
In the contemporary study, a Double Beam UV-Vis spectrophotometer was used to measure in vitro radical scavenging activity percentage and ascorbic acid contents in some selected Chenopodium species. Ascorbic acid content of some selected Chenopodium species was determined by the 2,4-Dinnitrophenylhydrazine method (DNPH). The DPPH methodology was utilized to determine the percentage of radical scavenging activity in the extract of Chenopodium species. The obtained results were denoted as mean ± standard deviation values. The maximum vitamin C amount in Chenopodium giganteum leaves was found to be 161.20 ± 0.008 mg/0.4g FW and the minimum was 51.07 ± 0.011 mg/0.4g FW in Chenopodium giganteum root. The leaves of Chenopodium species have had the highest percentage of radical scavenging activity. The obtained results were indicating that Chenopodium species are potential sources of natural antioxidants and vitamin C.
