Abstract
Seed germination experiments were conducted with 10, 20, 50, 100, 200 and 500 mM NaCl stress at 34.3 ± 5.2°C of summer and 17.6 ± 3.4°C of winter in laboratory conditions. Highest germination (92.33±4.50%) was recorded with 50mM NaCl at 34.3 ± 5.2°C. Seed germination (70.00 ± 3.00%) significantly (P=0.05) decreased in 500mM at 34.3 ± 5.2°C whereas seeds failed to germinate with this NaCl concentration at 17.6 ± 3.4°C. Radicle length (6.73 ± 2.23cm), dry weight (0.69 ± 0.06g) of 100 seeds and germination index (773.00 ± 9.6) were also significantly (P=0.05) increased under 50mM NaCl at 34.3 ± 5.2°C when compared with the control. Seed germination and seedling growth parameters were significantly (P=0.01) decreased under 500Mm salinity at 34.3 ± 5.2°C. Comparatively, the seed germination decreased in control and all the salinity treatments at lower temperature (17.6 ± 3.4°C). Seed dry weight and germination index also significantly (P=0.01) decreased whereas total spread of germination increased at 17.6 ± 3.4°C.

Abstract
Sericulture is an agro-based industry providing employment to millions of rural as well as urban population. The Sericulture industry depends on the production of good quality of cocoon. The quality and quantity of Cocoon depends on the nutrients of the leaf. The nutrient of the leaf comes from the soil. The rhizobacteria present in their soil plays important role in solubilizing the insoluble form of nutrient making them available to plant. The current study was carried on the microbial population of Tasar growing region. The isolate was examined on the basis of their color and surface morphology. The biochemical test starting from gram staining test, carbohydrate fermentation test (Glucose, Lactose, Mannitol and Sucrose), Litmus milk test, Catalase test, IMViC test, Urease test, Gelatin hydrolysis test, Nitrate reduction test Starch hydrolysis test and Triple sugar test. 16rRNA analysis was carried out for 4 isolates. According to morphological, biochemical characterization it was found that the isolates belong to the genus Bacillus spp., Pseudomonas spp., Planoccocus spp., and Azotobacter spp. On the basis of 16S rRNA analysis of 4 isolates were found to be Planococcus halotolerans SCU63(T), Bacillus tequilensis KCTC13622(T), Bacillus megaterium NBRC15308(T) and Bacillus zhangzhouensis DW5-4(T). This finding suggest that identified strain may be utilized as biofertilizers after further screening their ability of nitrogen fixation and phosphate solubilization capability because soil fertility is the major factor in the sericulture industry for the production of good quality crops.

Abstract
Early blight (Alternaria solani) of tomato is one of the major biotic constraints in different ecologies the world. The highly loss in yield and quality of fruits leading to complete defoliation, are the most damaging in regions with heavy rainfall, high humidity and fairly high temperatures (24-29ºC). The objective of this research was to compare between higher diseased incidence plant and lower diseased incidence plant based on yield as the measuring parameter in natural epiphytotic conditions. A line × tester analysis was conducted for evaluation of early blight disease of tomato in the Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (India). Thirteen lines and thirty hybrids were screened in randomize block design with three replications following standard spacing under natural epiphytotic conditions against early blight of tomato in two rabi (winter) seasons. In first year, the maximum disease severity was recorded for the hybrid NDTVR-60 × KashiSharad (42.66%) with a minimum severity of 24.00% in Flora dade x BT 12 however, in second year maximum disease severity was also recorded for the cross NDTVR-60 × KashiSharad (44.00%) and minimum for Floradade × BT-12 (24.00%). In the first year, twenty-three hybrids were moderately resistant while six hybrids showed susceptible reaction and one of the hybrid (Flora dade × BT-12) showed resistant reaction for the early blight. In second year, twenty-two hybrids showed moderately resistance and seven hybrids were found susceptible. Data showed higher disease incidence was responsible for decreasing yield per plant in both the years and also identifying resistant cultivars for further research work.

Abstract
The development of biological processes for the synthesis of nano-sized materials is of great importance in the field of nanotechnology. The present study deals with correlation between metal tolerance ability of bacterial isolates and its ability to synthesize Zinc oxide (ZnO) nanoparticles. Twenty-three bacterial cultures were isolated from zinc contaminated soil samples around close vicinity of zinc electroplating industries situated in Satpur MIDC of Nashik city, Maharashtra (INDIA). Among all twenty-three isolates, isolate SB3 was found to have maximum metal tolerance of 1000µg/mL which was identified as Bacillus mycoides on basis of morphological and biochemical characters and confirmed using VITEK 2 system. The extracellular biosynthesis of ZnO nanoparticles was performed using Bacillus mycoides and 1mM Zinc sulphate heptahydrate as a precursor. Recovery of nanoparticles was done using a mixture of CTAB and Hexane in the ratio 2:1 respectively. The synthesized ZnO nanoparticles were further characterized by using UV- Visible double beam spectroscopy, XRD and SEM confirming the crystalline spherical structure of ZnO nanoparticles having Z-average of 55nm. FTIR Spectroscopy studies indicated the presence of protein moiety for stabilization of formed nanoparticles. Thus, biological synthesis is an ecofriendly and cost-effective way to produce small sized and naturally stable ZnO nanoparticles.

Abstract
Piper betle L. leaf a heart shaped evergreen medicinal herb is traditionally used for the treatment of various diseases. The raw leaves as well as its extract shows significant antimicrobial activity, bactericidal activity, antifungal activity, immunosuppressive activity, anticancer activity, antiseptic, anti-inflammatory and anti-helminthic effects and are also used to prepare many Ayurvedic medicines. Ehanol extract of Piper betle L. leaves were prepared and its antimicrobial activity against gram positive and gram-negative bacteria were investigated. It was found that the leaf extract was effective against gram positive and negative microbes. The phytochemical analysis showed the presence of phytochemical compounds Flavinoids, Tannins, Steroids and Terpenoids. The presence of these phytochemical compounds suggests the possibility that phenolic compounds proved to be bactericidal. The experiment relating Piper betle L. leaves may be taken further in assessing the phytochemical component structure and properties and their role in bactericidal activity.

Abstract
Water is one of the most valuable resources. It covers over 75% of the earth's surface, although just 2.5 percent of all water is fresh in nature. Most of this fresh water resource is in the form of ice and snow, which is inaccessible to mankind, therefore, groundwater becomes increasingly important due to its accessibility. Over the years groundwater has got contaminated due to rapid industrialization, urbanization, high population, and advanced techniques in agriculture. Around 37.7 million people in India are affected by water-borne diseases, which kill 1.5 million people each year. Groundwater quality is being analyzed all around the world to understand its distribution and level of contamination. Chemical, biological, and physical properties of water are used to assess the quality of water in a specific area. In our study weighted arithmetic water quality index method has been used for overall water quality analysis in a more easy and reasonable manner. Values in weighted arithmetic water quality index method ranges from 0 to more than 100. The output value near 0 represents excellent water quality and the values approaching 100 represents very poor water quality. In our study water samples from the Kandi area showed a low water quality index ranging from 10.87 to 43.81 with an average of 28.85 while the water quality index values of Outer plains range from 43.13 to 94.47 having an average of 57.77. Thus, the hand pumps are good in water quality and therefore suitable for drinking purposes in the Kandi area. On the other hand, the water quality of handpumps in the Outer Plains varies from good to very poor water quality category and hence the water from most handpumps in the Outer Plains is unfit for drinking purpose. The study provided an insight about the status of water quality of handpumps which can be used for proper planning and management of water for sustainable water development.

Abstract
Soil is one of the important components of environment which affect growth and development of plants. The soil testing is one of the chemical processes in which the suitability of essential nutrients is determined. The objective of this research is to analyze physiochemical properties including pH, electrical conductivity, salinity, soil moisture, organic carbon, macronutrients (P, K, S) and micronutrients (Mn, Fe, Cu, Zn) in order to understand the suitability of soil for growth of threatened medicinal plant species in the study area. A total of 15 composite rhizospheric soil samples of two medicinal plants were collected and categorized into low, medium and high altitudinal soils. Variation existed in the estimated chemical parameters due to varied ecological conditions. The soil samples collected from low land and medium land soils were neutral to slightly alkaline, while those of high land were acidic. All soils were high in organic carbon and medium in available nitrogen, phosphorus and potassium. However, the study data showed that soil exchangeable manganese was maximum in Gulmarg and Doodhpathri whereas least was found in KUBG. Likewise, the higher iron, zinc and copper contents were reported at Gulmarg and least at other two studied sites. Therefore, the present study may act as baseline for artificial cultivation and conservation of the studied threatened medicinal plants by making appropriate soil amendments in near future after proper investigation.

Abstract
Goldenrod (solidago canadensis) a member of the Asteraceae family and also an important landscape plant. Most of them are herbaceous perennial growing from woody caudices or rhizomes. Goldenrod is one of the popular commercial cut flowers and also an excellent filler material. Fillers add a textural contrast as well as it is said to be the backbone of floral decorations. In floriculture industries, postharvest losses of flowers are the major problem due to its highly perishable nature and it ultimately affects the quality and vase life of flowers. To overcome these issues proper postharvest practices are essential. Adding chemical preservatives to the holding solution is recommended to prolong the vase life of the cut flowers. All holding solutions must contain essentially two components sugar and germicides. The sugar provides a respiratory substrate, while the germicides control harmful bacteria and prevent plugging of the conducting tissues. Among all the different types of sugars, sucrose has been found to be the most commonly used sugar in prolonging vase life of cut flowers. The present experiment was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalai Nagar during 2018-2020. The experiment was repeated three times with five replicates in completely randomized design. the treatment consisted of five preservative chemicals viz., 8-hydroxy quinoline sulphate, citric acid, silver thiosulphate, Aluminum Sulphate and Gibberellic acid @ 200 ppm were used alone and also in combination with the treatment sucrose @ 4% along with control (distilled water). The results showed that all treatments had improved the keeping quality and vase life of cut flowers when compared to control. Among all these treatments. The results of the experiment revealed that T6 (Al2 (SO4)3 @ 200ppm + 4% sucrose) obtained the higher water uptake, reduced transpirational loss of water, water balance, fresh weight, lowest cumulative physiological loss in weight, flower freshness, flower discolouration, vase life and ornamental value compared to control.

Abstract
Nanomaterials have been widely applied in different fields of science, such as biotechnology, microbiology, environmental remediation, medicine, various engineering, and material sciences, because of their peculiar properties. For biomedical and ecotoxicological concerns, it is necessary to evaluate their biocompatibility at the molecular level. The green production of magnesium oxide nanoparticles is investigated in this study using Crescentia cujete leaf extract (MgONP). The synthesized MgONP has a dimension of 626 nm and a hydrodynamic diameter of 246 ± 12, according to FE-SEM and dynamic light scattering (DLS). MgONP was stable in fish medium, with a zeta potential of 19 ± 10 mV. The current work assesses the biocompatibility of produced nanoparticles using the zebrafish model, which is a well-established animal model for biocompatibility due to its quick development, transparency, and strong genetic similarity to humans. The influence of the produced nanoparticles on development was studied to determine biocompatibility.

Abstract
Paddy is a very important cereal crop having the highest productivity in the world. India stands second in paddy production in the world and it is self-sufficient in paddy production. Generally, the success of paddy cultivation depends upon knowledge and adoption of recommended paddy cultivation practices by the farmers, but the so-called new farming technologies are still remaining unrealized due to many problems and constraints in the southern states of India. Paddy is commonly grown in a traditional way by majority of the famers in Pudukkottai. So, they were not much aware of the paddy farming technologies. Keeping this point in mind, this research study was undertaken to analyze their knowledge on recommended paddy cultivation technologies. Keeping this in view, the study was carried out selected six villages in Aranthangi block of Pudukkottai district. The sample size consisted of 120 paddy growers. The respondents were interviewed personally through a well-structured and pre- tested interview schedule. Arithmetic mean, percentage analysis, cumulative frequency, zero order correlation and multiple regressions were used for analyzing and interpreting the data. The study revealed that majority of the respondents was found to be middle aged, have possessed formal level of education. Majority of them were found to be small to marginal farmers with medium level of experience in paddy cultivation. With regard to the dependent variables namely knowledge and adoption both the variables had exhibited medium to low levels on recommended paddy technologies. out of the fourteen variables studied only five variables viz., age, educational status, social participation, mass media exposure, risk orientation was found to have significant and positive relationship with knowledge level of respondents. Among the significant variables, the variable social participation was found to be significant at one per cent level of probability.

Abstract
Vermicompost quality depends on the organic substrate acted upon by digestive enzymes in the gut of earthworms. Extent of enzyme activity varies depending upon the substrate and stage of vermicomposting operation. Keeping earlier observations in view, present study was undertaken to analyze enzyme activity in earthworm gut during various stages of vermicomposting of corn cob and cauliflower wastes using the earthworm species Eudrilus eugeniae. During the vermicomposting operation, the gut content of Eudrilus eugeniae was sampled at pre-determined intervals for enzyme analysis. Enzymes such as amylase, invertase and urease were estimated using standard protocols. Present investigation revealed that corn cob waste showed better enzyme activity as compared to cauliflower waste. Quantitative analysis of the enzymes recorded maximum amylase and invertase activity to be 11.2 and 9.6 µg ml-1 min-1 and 8.33 and 6.46 µg ml-1 min-1 on the 30th day; whereas, maximum urease activity was found to be 3.8 and 6.1 µg ml-1 min-1 on the 45th day; in gut content of Eudrilus eugeniae fed on corn cob and cauliflower waste, respectively. Organic wastes generated in large amounts, can be used as good organic substrates in vermicomposting using the earthworm species Eudrilus eugeniae, and thus be helpful in waste management.

Abstract
Sclerotium rolfsii Sacc. is one of the major phytopathogen of Groundnut causing Stem rot disease, which was tough to control by conventional means by applying fungicides. Therefore, in the present investigation, an effort is being made to search for effective control measures in terms of biocontrol agent for the Stem rot disease. In the present research, 58 Pseudomonas strains isolated from rhizospheric niches were screened for their biocontrol activity against S. rolfsii under in vitro conditions. One of the identified strain, Pseudomonas aeruginosa AL98 was selected for further studies because of its ability to content the mycelial growth of the pathogen significantly.

Abstract
India ranks second in cashew nuts production compared to other countries in the world. It is also the largest supplier of cashew kernels to the major world markets. Information processing behaviour of cashew growers refers to all activities performed by the farmers for evaluation, treatment and storage of the scientific and technical information about the cashew cultivation received by them. A study was undertaken to analyze the information processing behaviour of cashew growers. The study was taken up at Cuddalore, one of the cashew predominant districts in Tamil Nadu State. A sample size of one hundred and twenty cashew growers were selected based on proportionate random sampling method. The study revealed that ‘weighing in the light of past experiences’ and ‘advantages of the message’ were the widely considered aspects for processing of information by majority of the cashew growers. The most widely used methods for information treatment were ‘cross checking with past experience’ and ‘discussion with friends and relatives’. In the case of information storage, majority of the respondents stored the information by ‘memorizing’ and ‘preserving information materials like booklets, leaflets etc’.

Abstract
Pseudomonas syringae is one of the predominant bacteria that cause pathogenic infections in a wide variety of fruits, vegetables and ornamental plants. This bacterium produces the toxin coronatine which force the plant to keep its stomata open through which it enters the plant. This infection gradually reduces the plant yield resulting in a great economic loss. Tomato (Solanum lycopersicum) plants infected by the bacterial speck pathogen Pseudomonas syringae pv. tomato was identified by the appearance of the lesions on the leaves and fruits. The pathogen was isolated from the collected samples and confirmed after performing biochemical tests. Phages that target this pathogen were isolated by suspending the collected samples in PBS followed by double agar overlay method. Isolated phages were subjected to purification using polyethylene glycol (PEG 6000) and an increase in the phage concentration from 0.87*103 PFU/mL to 1.05*103 PFU/mL was observed. The concentrated phages were found to be stable when stored at -20°C in PBS (Phosphate Buffer Saline) solution. The host range of isolated phages were tested by checking their lytic activity against beneficial pathogens such as Pseudomonas fluorescens and Bacillus subtilis found in tomato plants. This study forwards the idea of engaging bacteriophages as effective biocontrol agents rather than employing the harmful chemicals to treat bacterial speck of tomato plants.

Abstract
Assam is primarily an agro-based rural economy where around 86 per cent of the total population still lives in rural areas. Using the secondary data from different sources the present study tries to find out the trends and determinants of agricultural wages of Assam. It has been observed that there is a significant gap between the agricultural wages of field labourers of Assam and India. Both money and real wages of male field labourers of Assam were very low till 2009-10. It is in the recent past only those wages have increased substantially for field labourers. Multiple factors could be attributed to this recent jump in rural real wages in Assam first continuous decline in participation of main agricultural workers, implementation of MGNREGA, rise in agricultural productivity, construction sector, urbanization, and rural literacy simultaneously contributed to the rise in rural wages. The regression analysis shows that the percentage share of agriculture and construction sector in district domestic product, rural male literacy, cropping intensity, irrigation intensity and have been impacting agricultural wage positively and significantly while land labour ratio impacts it negatively and significantly. On the other hand, a crucial factor like Agricultural Productivity and MNREGA although shows the expected sign but not significant. The study suggests that since there is a significant gap between national and state average wages, therefore, appropriate policies should be designed to arrest the gap. At the same, the government should take appropriate steps for increasing agricultural productivity which has a major bearing on agricultural wages along with the proper implementation of monitoring of MNREGA is also important.

Abstract
Biochar is a solid product obtained from pyrolysis of biomass. Biochar is a stable, carbon rich form of charcoal that is applied to soil. This carbon enriched porous material which can be used for a broad spectrum of applications, among which crop enhancement, soil improvement, soil remediation, carbon sequestration and pollution control were take the most important roles. Pesticide pollution and soil degradation are two major problems in the agricultural ecosystem. In addition to that, every year Indian farmers are adversely affected by various constraints in relevant to changes in monsoon, crop quality, declining crop production and soil fertility. Since they have no viable option to dispose the residual crop wastes in each season, they often resort to crop burning in North India and this causes a spike in air pollution every year. Application of biochar is the efficient and economical way to potentially manage these problems. Recently biochar gained interest and importance as a way to deal with agricultural ecosystem. Many studies have demonstrated the positive influence of biochar on soil quality, fertilizers efficiency, plant growth as well as soil microbiota. In worldwide research on biochar has increased drastically over the past decade. In India many numbers of studies in biochar have gone up in the past few years. The main objective of this review paper is to discuss the biochar features and its applicability in various agricultural practices in related to improve soil productivity, plant growth and development. From this review it could be concluded that, use of biochar in agricultural and environmental ecosystems is one of the viable options to improve soil productivity, plant growth and development. Available research evidences strongly justify that continuous research and development efforts need for understanding more about the benefits, potentiality as well as limitations of biochar and expanding its uses for agriculture in economical way.

Abstract
This study was undertaken to assess the limnochemical profile of River Kaushiki, a distributary of River Damodar at pre-designated sampling sites, and to evaluate the impact of the pollution load on water quality of this river. The water quality data was collected from June-2019 to March-2020. Different limnochemical parameters were monitored in five sampling stations, namely Bahirkhanda (KD-1), Prasadpur (KD-2), Munshirhat (KD-3), Gobindapur (KD-4), and Banharishpur (KD-5). The pH range found in the studied stretch of the river indicated that it was sub-alkaline (6.77-8.24). Poor dissolved oxygen (DO) levels were evident at KD-3(1.73 mg /L) and KD-5 (1.91 mg/L). Total dissolved solids (TDS) levels ranged from 101.46- 423.51 mg/L. Relatively higher TDS and Electrical conductivity (EC) values were recorded during the post-monsoon months. KD-3 and KD-5 had shown high mean EC levels of 421.3 µs/cm and 453.2 µs/cm, respectively. High nitrate and phosphate concentrations were found in this river, particularly during the late monsoon or post-monsoon months at KD-3 & KD-5 sampling stations. The water quality of KD-5 and KD-3 sampling stations was relatively poorer than that of other sampling stations. Several processes like metabolic activities in water, synergies of pollution load, sediment characteristics regulate the water quality of this river. This study could provide baseline data if any monitoring and restoration programme for this riverine is undertaken in future.

Abstract
Ipomoea pes-caprae (Linn.) Roth, sometimes known as beach morning glory, is a Convolvulaceae family mangrove related medicinal plant that thrives in tropical and subtropical climates. The leaves of I. pes-caprae collected from the coastal areas of Kalpakkam, Chennai, were prepared with various solvent extracts (hexane, chloroform, methanol) and aqueous extract and tested for phytochemical and antibacterial activity. The presence of phytochemicals such as alkaloids, glycosides, terpenoids, steroids, flavonoids, quinones, phenolic compounds, tannins, and saponins in all the extracts is shown by qualitative phytochemical analysis. The presence of alkaloids, flavonoids, phenols, and tannins can be determined via TLC profiling. Methanol was found to be the most successful of the four solvents in extracting the most secondary metabolites. On Gram-positive and Gram-negative bacteria, the antibacterial activity of different extracts was tested in vitro. The zone of inhibition found by the agar well diffusion method differed depending on the plant extract, extraction solvent, and organism examined. Against Pseudeomonas sp., the methanol extract produced the largest inhibitory zone (3 ≥13 mm). These findings suggested that I. pes-caprae, which is wildly grown, could be a source of pharmacologically active phytochemicals.

Abstract
Agriculture is the prime occupation of Indians. Majority in rural India is still dependent on the agriculture. A lot of research works on agriculture and crops happen every day. Agriculture in India is believed to be strengthened through modern agricultural practices. A lot of agricultural commodities are exported from India to all over the world. Indian beverages and spices are most popular agricultural products across the globe. Soil is the vital part of agriculture. Farmers can enhance their yield and income by knowing more about the soil. Farmers must be guided correctly regarding the soil health and crops so that unforeseen conditions can be avoided. If soil is tested and fertility rate of the soil with yield estimation is informed to farmer, it will be beneficial for him to continue the agriculture in right way. Based on soil quality and his other conditions farmer can choose the right crops and fertilizers for his land. In this paper we have discussed about the bagging approach which is a machine learning (ML) technique used for implementing soil fertility and yield prediction. We have considered some soil parameters such as pH, Nitrogen, Phosphorus, Potassium (NPK), humidity, temperature, organic carbon, moisture content and rainfall to predict the soil fertility and crop yield. We have also discussed about the test results and checked with other approaches of soil fertility & yield predictions to compare the performance of models.

This paper reflects the comparative analysis of Phyto-sociological data of kuldiha and Hadagarh Wildlife Sanctuary, Odisha, India. The main objectives of our study are to identify and classify the vegetation of both the sanctuaries under the Similipal Biosphere Reserve. The study was done following the standard methods which are widely adopted for the phytosociological study like quadrate method. The present study concluded with the fact that despite sharing the common vegetation which is the tropical moist deciduous forest, the dominant species of the sanctuaries differ. The dominant tree species of Kuldiha was found Terminalia tomentosa (IVI- 290.75) and at Hadagarh it was Shorea robusta (IVI-285.12). The potential anthropogenic factors influence of cattle and herbivores and the demon fire are rapidly engulfing the density of the vegetation and its aesthetic beauty. Prompt and effective actions are needed to be implemented to preserve both the sanctuaries from biodiversity loss.

Abstract
Cotton, the most important fiber crop of India plays a dominant role in its agrarian and industrial economy. Pest management approach of varying degrees of sophistication has been applied for insect control in all cotton-producing areas of our country. During the coevolution of plants and insects, plants have biosynthesized a number of secondary metabolites to serve as defense chemicals against insect attack. Plants appear to produce a wide variety of secondary metabolites as defensive weapons. Such defensive chemicals are far superior to the synthetic pesticides. It concludes that the isolated polyphenolic biopesticide from Streblus asper (PBSA) was found to have noteworthy insecticidal activity to Dysdercus cingulatus (red cotton bug) with an LD50 of 0.894 µg/insect by residual film technique and 0.595 µg/insect by topical application. Significant inhibition in activities of acetylcholine esterase (AChE), antioxidant enzymes and glutathione-S-transferase (GST) and significant increase in the lipid peroxides (MDA) lead to the fact that Dysdercus cingulatus become more susceptible to the tested biopesticides. The present study has provided some basic information on the mechanism of insecticidal action of polyphenolic compound that will be useful to the development better management strategies. This may provide a useful beginning for the development of eco- friendly biopesticides.

Abstract
The weather parameters play an important role in application of pest management practices. The study on the influence of major abiotic factors viz., maximum temperature, minimum temperature, morning relative humidity, evening relative humidity, rain fall, rainy days, sunshine, wind speed and evaporation against insect pests of Bt Kaveri cotton hybrid. The results revealed that significantly negative correlation of aphids, whiteflies and mealybugs was found with all abiotic factors except sunshine. Significantly positive correlation of leafhoppers was recorded with rainfall, morning relative humidity, rainy days and evening relative humidity and not significantly positive correlation with minimum temperature. Thrips were found highly significantly positive correlation with sunshine and not significantly positive correlation with morning relative humidity. S. litura population was recorded highly significantly positive correlation with rainfall and all others were negative effects on S. litura population. Overall, all the abiotic factors except sunshine have shown negative correlation with pests of Bt Kaveri cotton hybrid.

Abstract
This study provides a preliminary knowledge on the diversity of ants in an orchard of alluvial soil. From the present study, it can be concluded that diverse vegetation supports greater ant diversity. But rapid and constant urbanization in this area leads to habitat destruction which has an adverse impact on ant diversity. This study is intended to serve as base line data for what was present during this period in a rapidly changing landscape. Detailed study may generate much more diverse ants’ fauna, which may consider as worthy to the taxonomic study on ants in West Bengal.

Abstract
Sugar industry is an agro-based industry that’s why it was propose to study the effect of sugar industry effluent on productivity, as irrigation medium in different dilution i.e., 20 per cent (T1), 40 per cent (T2), 60 per cent (T3), 80 per cent (T4) and 100 per cent (T5). The nutrient element generally present in the effluent are phosphorous, zinc, magnesium, iron etc. productivity per plant is affected with the irrigation of sugar industry effluent. Treatment T1, T2, and T3 showed significantly increase by 32.21 per cent, 59.12 per cent and 98.16 per cent respectively as compare to the control crop.
