Abstract
The environment is contaminated with Heavy Metals (HMs) with increasing HM pollution due to various human and natural processes. An Arbuscular Mycorrhizal Fungi (AMF) is the large amount pervasive soil vegetative symbiotic fungus in the terrene environment and mitigates the noxious property of discrete contaminants on both natural and agricultural crop plants. In addition to AMF also repress various antagonistic and assistance bacteria such as root pathogens, PGPR including free-living and symbiotic N2-fixers, and pinch-hitting as microbial fertilizers, and microbial degraders. The experiments were carried out of the black gram seeds were sown in pots, the pots containing 5 kg of soil with AMF inoculation and adding different proportion of Cr [(Potassium dichromate (VI), K2Cr2O7]. Three repeats were maintained for each level. Under these investigational conditions the morphological parameters like shoot and root length, number of leaves, total leaf area was inspected with 15, 30, 60 and 75th DAS and yield parameters like number of pods/plants, amount of seeds/plants and 250 seeds weight was recorded. The nutrient content such as N, P, K, Ca, Zn, Fe and Cr of black gram was recorded in 75th DAS of dry plants. The end of the results Cr contaminated soils were decreased the growth, nutrient contents and yield parameters when compared to AMF inoculated plants. Additionally, the profitable effects of the AMF observed in this study aroused an interest in considering the role of AMF in plant-based strategies of protection of highly Cr-polluted soils.

Abstract
A research study was done to find the effective method of banana ripening. The fruits were treated with four doses of Ethephon (200, 400, 600 and 800 ppm), three methods of application (placing cotton dipped Ethephon inside the poly bag, plugging cotton dipped Ethephon at the neck of a poly bag and dipping the fruits in an aqueous Ethephon solution) and one control. The experiment was laid out in a Factorial completely randomized design against other treatments (control). Analysis of data showed that there was significant effect in methods of application over the physiological loss in weight, shelf life, total sugar, reducing sugar, total soluble solids and titratable acidity. Significant difference was also observed in interactions between doses and methods over the fruit firmness, fruit weight, palatability and all chemical characteristics. Fruits treated with 600 ppm gave better total sugar (10.81%), TSS (21.97°Brix) and titratable acidity (0.3%). Among the methods of application fruits that was ripen by released of Ethylene through cotton dipped Ethephon plugged at the neck region of the poly bag gave better shelf life and less weight loss than that of dipping method. The untreated fruits are poor in flavour and quality.

Abstract
Among agriculture crops, Sericulture being one of the most assured income generating crops supporting the livelihood of many farmers in India. Of the several parameters determining the healthiness of mulberry silkworm (Bombyx mori) larvae and success of cocoon crop, the germ-free rearing environment is crucial. Thus, it is in vogue to perform disinfection of rearing house and equipment’s before onset of rearing to grow disease free silkworms. Despite, scientific information’s are available in this regard, still heavy cocoon crop loss is reporting at field. To uncover the lacuna underlies, we have conducted a systematic assessment on disinfection strategies being followed by the farmers and the problems associated with it. Surprisingly, the present analysis revealed that all most all farmers did not adopt appropriate procedure for disinfection of the rearing house. However, the type of disinfectants, concentration and quantity as per the floor area used and the disinfection procedure followed were uncommon in both the villages. Interestingly, while cent percent of farmers in Koregala village using Decol, farmers in H. Kodihalli were using Chlorophate. In addition, although, all farmers have been practicing an advanced method of silkworm rearing-shoot rearing, correspondingly suitable disinfection procedure has not been followed. Thus, in order to overcome these constrains, based on the lacunae detected in the present investigation, we have developed a farmer-specific and user-friendly key termed as “Disinfection Card and a mobile application - SeriApp” to enable the farmers to disinfect their rearing houses with ease and accurate.

Abstract
In this present research study, the superoxide dismutase and glutathione peroxidase contents were determined in pupal developmental stage of the Silkworm, Bombyx mori L. The two bivoltine (CSR2 & NB4D2) and two multivoltine races (Pure Mysore & C.nichi) were selected for the study and rearing was conducted as per the standard rearing method and after the rearing good cocoons were selected for further assessment. The male and female sex were separated during 5th instar just after resuming from 4th moult before feeding to identify the male and female pupae on 3rd day after spinning. The fat body samples were extracted from male and female from 3rd day to till last of pupal duration. The extracted samples were kept at -20oC for preservation and utilization for the analysis of enzyme profiles viz. Superoxide dismutase (SOD), Glutathione peroxidase (GPx) as per the standard estimation procedures. The results showed stage-specific significantly higher trend levels of glutathione peroxide contents in the female and male pupae as compared to the superoxide dismutase level on (p<0.05). However, a significantly higher level of glutathione peroxidase activity was observed in female pupa on 3rd day of CSR2 breed (p<0.05). In the case of male pupae of four selected races, significantly lower level of superoxide dismutase activity was observed (p<0.05). Correlation analysis clearly revealed differences in the way the enzyme activity level is equilibrated for a particular stage and developmental pattern. Hence, in this research study, it is very clearly that, the results obtained could be the effect of intensive metabolic transformation that takes place in tissues of the non-diapause generation and causes increased production of reactive oxygen species, such as hydroperoxides. The results of this study suggesting that antioxidants plays a key and fundamental role in the total defense mechanisms and also protecting cells against reactive oxygen species (ROS).

Abstract
A field experiment to study the effect of different dates of sowing on Stigma receptivity in parental lines of sorghum hybrids was conducted during Kharif. Stigma receptivity was studied for four sterile ‘A’ lines viz. AKMS-14A, MS-27A, MS-70A and MS-296A of Sorghum hybrids at three different sowing dates. In all sowing dates Stigma of seed parent MS-27A remained receptive up to ‘6’ day with highest receptivity on ‘0’ day and lowest at 6th day of starvation period whereas it remained receptive up to ‘5’ days in other seed parent as judged by seed setting percentage. Seed parents was significantly better upto 2 to 4 days of starvation after complete flowering in Kharif season. On an average stigma receptivity was significantly highest at ‘0’day starvation and subsequently reduced due to delay in pollination. Pollen viability was studied for restorer (R) lines AKR-150, C-43, ICSR-89058 and AKR-73 of sorghum hybrids at three different sowing dates. In all sowing dates pollen viability of seed parent AKR-150 was viable upto 6 hours and highest at 8 AM in D1. Seed setting was highest at 8 AM for seed parent AKR-150, ICSR-89058 and AKR-73 except C-43, wherein, highest seed setting was observed at 9 AM.

Abstract
The present study was undertaken in Vijayapura district of Northern Karnataka for the year 2018-19 with the objective of evaluating economically the value addition in grapes. The multistage sampling was adopted to select the district, talukas and villages. The study objectives were analyzed using budgeting technique and financial feasibility tools. The results of the study highlighted that, though the cultivation of grapes involved more investment but in turn it yields positive net returns to the cultivators. When farmers sold their produce by making fresh grapes in to raisins, they got additional returns of about ₹ 1,86,489.00. Based on the results of the study we can conclude that the investment on grape vineyards are financially feasible in the study area and project is strongly recommended to the farmers for continuation in future as well.

Abstract
The present study was carried out to analyze biochemical parameters of Sesamum indicum L. by treating the plants with fertilizers and manures at University of Rajasthan, Jaipur. The experiment consisted of five treatments named as T1- control (without any manure or fertilizer), T2- urea as nitrogen fertilizer, T3- urea + diammonium phosphate as N+P fertilizer, T4- vermicompost, and T5- a combination of vermicompost + biofertilizer. These were evaluated in a complete randomized design with four replications. Biochemical parameters taken for the study were- lipids, proteins, total soluble sugars, starch, phenols, and two antioxidant enzymes: peroxidase and catalase. Experimental results showed that chlorophyll-a, b, total chlorophyll, protein content, lipids, and peroxidase were observed maximum in vermicompost treated plants. Total phenols were observed increased in vermicompost + biofertilizer treatment. Therefore, they can be used to enhance the above parameters as an alternative of inorganic fertilizers under the arid conditions of Rajasthan. However, carotenoids, TSS, starch, and catalase were found higher in control plants. These parameters were not influenced significantly by fertilizer and manure treatments. It suggests that an optimized fertilizer rate is necessary to ensure agricultural sustainability in respect of synthesized food and antioxidants.

Abstract
An experiment was conducted to determine the effect of mycorrhizal fungi inoculation on growth of garlic grown under well-watered and water stressed pot culture conditions. Garlic (Allium sativum L.) cloves were planted in furrows. The data was collected at an interval of 15 days. Colonization of root with Arbuscular Mycorrhizal (AM) fungi occurred in under water-stressed and well-watered conditions, but the extent of AM fungi root colonization was higher under well-watered than under water stressed conditions. Regarding length of leaves, root, weight of bulb and diameter of garlic after 45, 60, 75 and 90 days, data was collected. The AMF-inoculated plants had higher fresh bulb yield and mean bulb weight than uninoculated plants However, inoculation with AM fungi has improved garlic bulb yield. The result indicates from AM fungi inoculation benefited more than that of especially under water-stressed conditions.

Abstract
Pentatomid bug Andrallus spinidens (F) is a predator on a wide range of insect pests in rice fields of east Vidarbha. The life cycle of A. spinidens was studied during the year 2018-2019 revealed that a single female laid an average number of 250 eggs in 3 to 8 batches and each batch contained 32 to 65 eggs. Incubation period on an average was 6.6 ± 0.03 days and 95-100% eggs hatching rate at 24 to 30°C temperatures with high humidity. Pri-oviposition and oviposition period was 1- 4 days. First, second, third, fourth, and fifth stages of the nymphal period were 2.3 ± 0.03, 3.3 ± 0.03, 3.6 ± 0.03, 3.6 ± 0.03 and 6 ± 0.05 days respectively. Second to fifth stages nymphs and adults of A. spinidens were feeding different stages larvae and pupae of a number of harmful lepidopteran pests in the rice field. In vivo and field study suggested that the first instar nymph of A. spinidens was non-feeding while, second, third, fourth and fifth stages nymphs were voraciously fed on 3, 4, 7 and 12 number of larvae and pupae of Melanitis leda respectively. Similarly, adult bugs fed on average 30 rice pest larvae of Melanitis leda and confirmed their predatory role in the rice field of Vidarbha region in Maharashtra.

Abstract
In the present study the preferential salvation of salts in sugar- aqueous system has been considered. It is carried out by using conductometric observation of analytical grade sugar and plantation white sugar aqueous system with salts viz. CaCl2, MgCl2, KCl, NaCl. It shows that the conductivity is in linear relationship with the electrolytes and non-sugar present in both analytical grade sugar and plantation white sugar over a range of 5 to 25 W/V percent. The optimum range of concentration found to be for both the sugars is about 20%. Encouraging results could be obtained in the determination of sugars i.e. non electrolytes and electrolytes in aqueous sugar solution products. The present study shows valid technological interest to understand Maillard reaction due to adoption of MgCl2 salt in place of sulphite. These sugars–salts complexes are responsible for the formation of molasses which leads to substantial loss of sugar of around ten percent of the total sugar present in cane.

Abstract
Polar Regions show a condition of extreme freeze with mean summer temperature below zero. Arctic and Antarctic areas are Polar habitats. Tundra's are the most common in the Low Arctic, while in the High Arctic, polar barrens dominate. The distinct phototrophic populations at the glaciers indicate the possibility of darkening on the ice surface for spatially varying processes. The term photoautotroph is an autotrophic combination, the term for an organism producing its own food, and the photo prefix, which means "light" in English. The study is done on the purpose of finding out the polar ecosystem and the materials and methods part of this study is basically related with the samples gathered from the polar regions, both the samples of soil and ecosystem is gathered. The results indicate that mineral loading differed among the glaciers on the Polar Regions. The distinct phototrophic populations at the glaciers indicate the possibility of darkening on the ice surface for spatially varying processes. The evolving structures can monitor the delivery of en- or sub glacial debris to the surface of the Ice, as well as modulate the hydrology.

Abstract
Indiscriminate use of synthetic fertilizers causes the contamination of the soil, water, and reduced soil fertility. Poultry farming carries a scope for rapid and large profit and become a remunerative business lead to continuously discharge an enlarged quantity of waste such as dead on arrival, feathers, and bones. Feathers are the rich source of keratin proteins and amino acids this factor makes feather applicable to produce of fertilizers and feather meal. The present study aim was to degradation of poultry chicken feathers and its conversion to Bio-fertilizer. Bacteria P3A and BS3B were isolated from feathers waste dumping area and identified as Staphylococcus epidermidis and Bacillus cereus respectively by the 16S rRNA analysis. It was found that crude enzyme had potential to breakdown the feathers. Bio-fertilizer produced from isolates P3A and BS3B shows 20 cm and 25 cm shoot length and 10 cm and 12.5 cm root length of wheat crop and 16 cm and 18 cm shoot length and 4 cm and 4 cm root length of chick pea crop respectively. Feather bio-fertilizer treated crops showed vigorous growth than the control crops. Keratinase enzyme was useful to convert poultry chicken feather waste into bio-fertilizer.

Abstract
In this study the export performance and extent of market integration in Indian fish trade was analyzed considering the following specific objectives viz. (i) to analyze the trends in the performance of Indian fish export and (ii) to examine the nature and extent of market integration between fish export markets in India. For estimating the degree of price transmission between different fish markets, five major export markets viz. Cochin, Chennai, Vizagapattinam, Kolkatta and Tuticorin were purposively selected, considering the higher degree of consistency in the export of shrimp through these ports. The daily export prices via the above mentioned ports were collected from the respective ports on daily basis. The study revealed that in all the years, value wise share of Shrimp was not less than 50 per cent of total fish trade of India. In a long run perspective reliance on this single item, shrimp does not reflect a healthy sustainable trend which needs to be addressed with. It is suggested that, the fishery export promotion agencies like MPEDA (Marine Products Export Development Authority) may take efforts to encourage and enhance the performance of all items of fish export as like Shrimp export. Co-integration analysis revealed that export markets of India are not integrated to the needed and required level. The data access to exporters on fish trade, to enhance market intelligence, should be made more liberal, faster and widespread to all export markets. Efforts need to be enhanced to coordinate relevant fishery and export agencies so as to ensure proper dissemination of market information on time to needed stakeholders.

Abstract
Pecan nut is one of the emerging nut crops of Jammu and Kashmir, drawing attention of government functionaries as well as the stakeholders involved in horticulture in UT of Jammu and Kashmir. The production from pecan nut trees started after 8 years with subsequent increase every year. The pay-back period of pecan nut orchard was 22.20, 24.11 and 26.18 years at 8, 10 and 12 percent of discount rate respectively. The net present value was ₹ 43,12,022, ₹ 19,85,900 and ₹ 6,72,510 at 8, 10 and 12 percent of discount rate respectively. At the same rate of 8, 10 and 12 percent of discount rate, the profitability index was 10.81, 5.61 and 2.60 respectively. The internal rate of return of pecan nut orchard was 14 per cent which shows that investing in pecan nut orchard will be a profitable venture until the market interest rate remains below 14 per cent. The value of gamma parameter was 0.00001 and was insignificant, reflecting the absence of technical efficiency in pecan nut production. The results highlighted the need for introduction of technical innovations without compromising the quality and uniqueness of the traits.

Abstract
A field experiment was conducted on black cotton soil for two consecutive rabbi seasons (2018, 2019) to investigate the effects of organic and synthetic fertilizers on growth and yield as well as seed quality of soybean crop along with soil health parameters using cultivar JS-335. The results revealed that combined applications of organic manures and synthetic fertilizer improved the growth and seed yield as well as oil content, protein and carbohydrate contents as compared to control and other treatments. Similarly, the various soil health parameters were also greatly significantly improved. The sustainable use of both organic and inorganic fertilizers together enhanced economic yield, agronomic efficiency, physiological efficiency, partial factor productivity, apparent recovery efficiency, sustainable yield index etc. It is concluded from the above experiment that combined application of RDF (30:80:20:40) + FYM & RDF (30:80:20:40) + VCM emerged as promising method for sustainable cultivation of soybean in the region of Sangli district (Maharashtra).

Abstract
The present study deals with the physiological characterization are 24 different strains of blue green algae. It includes the pigment profiles which deals the estimation of chlorophyll, carotenoids and phycobilins (phycocyanin, allophycocyanin and phycoerythrin) in different strains. The pigment analysis showed that the maximum chlorophyll-a was estimated in Microchaete uberrima. The ratio of pigment in all the strains indicates the occurrence of maximum amount of phycobilins and then carotenoids. All these pigments are not present always in same relative proportion.

Abstract
Watermoulds are known to attack eggs and fries of fishes and as a general rule the infection starts when the host gets injured either mechanically or as a result of infections other than fungal. The present investigations have shown infection on eggs and fries of Labeo rohita L. and fries of Macrobrachium lamarrei Milne Edw. (prawn) by Saprolegnia diclina Harvey, Achlya diffusa Nees von Esenbeck and Pythium oligandrum Dreschler. The pathogenicity of the fungal isolates has been tested using healthy and disease-free eggs and fries of Labeo rohita and fries of Macrobrachium lamarrei. In the in vitro test experiments, the pathogenic nature of all the fungal isolates has been confirmed.

Abstract
The article mainly examined the awareness among the farmers about the agricultural pollution caused due to pesticides, fertilizer, harvest waste, sewage water and irrigation water. Data were collected from 120 randomly selected respondents from Nagpur and Kampthee tahasil of the Nagpur district through personal interview method. The overall awareness index about agricultural pollution caused by different practices of crop production indicated low level of awareness among 51.67 per cent of the respondents. The findings of the study further revealed that 59.17 per cent of the farmers were aware about the harmful effects of pesticides on human health, as well as high application of pesticides can contaminate water sources was known to 51.67 per cent of the respondents. Awareness was also noticed among the (48.33%) respondents, due to excessive application of fertilizers it affects the soil properties. 55.83 per cent of the respondents were aware the fact that salt and silt could be deposited in soil due excessive irrigation and 52.00 per cent respondents were aware about waterlogged condition affects the plant growth. Improper disposal of harvest waste can create favorable condition for various diseases in succeeding crops were known to the 47.50 per cent of the respondents. The respondents were not aware about excessive use of pesticides causes leaching of poisonous chemicals into ground water and pesticides had residual effect on food grain, vegetable and fruits (62.50%), saline water affects physio-chemical properties of soil and it effects crop growth (78.33%) and burning of harvest waste emits carbon dioxide, carbon monoxide and methane in the atmosphere (73.33%), respectively.

Abstract
Cashew is one of the important plantation crops with its significant contribution to the country's foreign exchange through export of cashew kernels. It was introduced in India from Brazil by the Portuguese in the 16th century. For cultivating cashew, farmers seek information from many sources. There are numerous sources, both interpersonal and mass media, localite and cosmopolite that are available to the farmers to feed information about latest technologies in cashew cultivation. A study was undertaken to know the information acquisition 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 ‘family members’, ‘friends and relatives’ were the foremost credible personal-localite sources of utilised by the cashew growers for receiving information. ‘Assistant Horticultural Officers’ and ‘Horticultural Officers’ were regularly used as their major channels by the cashew growers for information acquisition. ‘Farm telecasts’ and ‘farm broadcasts’ were the most utilised impersonal-cosmopolite sources by the cashew growers for acquisition of information.

Abstract
Enhancing the agricultural productivity has become the top priority, worldwide because of the exponential demographic expansion. However, the present agricultural scenario of eco-system degradation warrants a sustainable approach to the agricultural production. The cropping system (cropping pattern and crop rotation) of an area has high bearing on both agricultural production as well as sustainability of the agro-ecosystem. Geospatial technology is gaining importance as useful tools in sustainable agricultural practices with time and cost-effective information. Therefore, monitoring the dynamic changes in the cropping system over a large area for the management and development of sustainable agro-ecosystem using geospatial technology is essential. The study has been conducted for Nathusari Chopta block of Sirsa district of Haryana state (India) based on multi-dated and multi-season Sentinal-2A/B; digital satellite data for the year 2018-2019. This paper is evaluating the role of cropping system analysis for agro-ecosystem sustainability. The unsupervised method of digital image classification is adopted with iterative self-organizing data analysis technique (ISODATA) approach. The NDVI approach is also used to improve the accuracy level of the digital classification for finding the non- agricultural classes like; forest, water bodies and built-up, etc. A total of 11 cropping patterns in the study area were identified and mapped. The net cropped area under kahrif, rabi and summer cropping pattern were occupied 71.81%, 86.50% and 30.50% respectively. These cropping patterns indicate that the area has the major crop rotations like: cotton-wheat/mustard, rice-wheat/mustard and gawar-mustard/gram were the dominant, occupied 26.31%, 23.55% and 8% of the total geographical area of the study area.
