Abstract
The accessory gland proteins (MAG) secreted in male moths are known to influence female reproductive behavior and physiology, when they are transferred along with the sperm during mating. Through, two-dimensional gel electrophoresis (2-DE) we have identified these MAG proteins in Helicoverpa armigera, a devastating polyphagous pest. The comparative analysis of virgin and mated male moths revealed a total of 139 and 154 protein spots respectively. The differentially expressed proteins following mating were, 25 over-expressed and 13 under-expressed. Further, 11 highly expressed protein spots unique to virgin males were analyzed using MALDI- MS and mascot search. The proteins detected were found to be involved in different functions such as, metabolism, spermatogenesis, oogenesis, olfaction, and protease inhibition.

Abstract
Genetic diversity among 288 Public sector developed tropical maize inbred lines was conducted at the research farm of Plant Breeding Division, (Indian Institute of Maize Research), Delhi and Ludhiana, India during Rabi and Kharif season 2015-17. The genotypes were grouped into six clusters. Cluster I comprised the maximum genotypes (64) which indicated the genetic similarity among them. The minimum genotype (24) was contained in the cluster II. The highest inter-cluster distance was observed between cluster IV and II (0.99) followed by cluster III and IV (0.83) and cluster V and IV (0.33) suggesting wider diversity between them and the genotypes in these cluster could be used as donor parents for new maize hybrid development. The highest intra-cluster distance was observed in cluster IV (0.99) and the cluster VI was had the least intra cluster distance (0.96). The positive absolute values of the two vectors revealed that ear height, ear diameter and yield (t/ha) had the greatest contribution to genetic divergence. The negative values for the two vectors for days to 50% tasseling, ear length and thousand seed weight (TSW) indicated the least responsibility of both the primary and secondary differentiations.

Abstract
In aqueous acetate buffer medium (pH = 3.42 - 4.8) hydroxylamine monosulfonate, (HONHSO3-) reduces the one electron oxidant, bridging superoxo ligand in [(dien)(en)CoIII(O2)CoIII(en)(dien)](ClO4)5 (1) to the corresponding hydroperoxo complex, [(en)(dien)CoIII(HO2)CoIII(en)(dien)]5+ (2) and itself gets oxidised to N2O gas and SO42-/ HSO4- following both proton coupled electron transfer (PCET) path and an electron – transfer reaction. The kinetics, stoichiometry and reaction mechanism clearly indicate that oxidation of HONHSO3- occurs through the formation of an intermediate aminoxyl (-O3SHNO.) radical. In the presence of excess HONHSO3- over 1, the reaction obeys first-order kinetics and rate of the reaction increases with [HONHSO3-]. The reaction rate, however, decreases with increase in [H+] and the plot of 1/ko with [H+] is linear with a small but significant intercept. The reaction rate also decreases with increase in ionic strength of the medium as expected for the two oppositely charged reactants. The decrease of reaction rate with [H+] is most likely due to the protonation of the superoxo complex 1, which leads to a kinetic dead-end product. It is also noticed that the reaction rate significantly decreases with increasing proportion of D2O replacing H2O in the solvent. Therefore, an H-atom transfer (HAT) from the reducing species to the bridging superoxide in 1 seems reasonable at the rate determining step.

Abstract
Genetic analysis for of seed yield was studied in a set of 6 × 6 full diallel crosses of sesame which indicated importance of both dominant and additive gene action. Estimation of genetic parameters like D, H1 and H2 was significant indicating the involvement of both additive and dominance gene effects for more characters. For plant height at maturity, number capsules per plant, number of seeds per capsule and seed yield per plant, the dominance factor were less than additive factors elucidating greater contribution of additive factors in control of this trait. For all other characters like, days to 50 per cent flowering, number of branches per plant, capsule length and 1000 seed weight, dominant factor was predominant for the inheritance of these traits.

Abstract
To evaluate the effect of chemical fertilizer treated and VA-mycorrhizal inoculated soybean, wheat and paddy biomass on mushroom cultivation of different species of Pleurotus (i.e. P. sajor caju, P. florida, P. ostreatus P. djamor) were cultivated on chemical fertilizer treated and VA-mycorrhizal inoculated soybean, wheat and paddy straws. Comparisons were with untreated/uninoculated control biomass. Mycorrhizal inoculated biomass was found to be significantly superior over chemical fertilizer treated and control biomass for mushroom yield. The yield of fruiting bodies obtained was significantly higher in mycorrhizal inoculated soybean biomass in comparison to wheat and paddy biomass. Pleurotus sajor-caju gave highest yield while P. djamor gave significantly poor yield among all the test species. An interesting point was finding out that all the three species of Pleurotus gave maximum yield in SS except P. djamor.

Abstract
The study was conducted in selected peri-urban blocks of Coimbatore district. The maximum average yield of bhendi was 14 tonnes per hectare with the coefficient of variation of 24.85 per cent. The maximum net return from bhendi cultivation reported that ₹ 27334 with the benefit-cost ratio of 1.22. The results of resource use efficiency revealed that quantity of nitrogen, number of irrigations and the human labour had a positive and significant influence on the yield of bhendi. The ratio of MVP to MFC was greater than one for all the significant variables indicating the underutilization of resources and there exists the possibility of enhancing their yield by increasing their use. The overall mean technical efficiency was 0.80, which indicated the possibility of increasing the yield of the crops by adopting better technology and cultivation practices.

Abstract
In this study one of the most important physical parameters identifying purity of cane sugar solutions is investigated. ICUMSA color values of S grades, M grades and L grades cane sugar are investigated of the season 2019-2020 at room temperature (25°C). The determination of color in solid phase was carried out by using Photovolt Reflectance meter. Obtained results for S grades, M grades and L grades cane sugar with different impurities are compared at such a given temperature. Color analysis proves that SS-31 grade of sugar has minimum impurity whereas; L-30 shows maximum impurities. It is evident that both ion solvent and the electrolyte - non-electrolytes is predominant in these systems, and the hydration of ions and the bonding tendency of sucrose and water also play an important role.

Abstract
Studies on extension of sericulture among the farmers of Jammu and Kashmir is always remained the prime focus of various extension workers because of the potential of the area to produce quality Bivoltine silk. The raw silk production is about 145 MT. But the production trends are not matching with other traditional states. As most, of cocoon growers belong to socially and economically weaker sections of society - SCs, STs and HTs, women and others. These families do not have any other source of sustainable income and depend on sericulture for the same. To keep pace with other states in India, there is need to provide a strong technical and financial support and ensure these families a sustainable livelihood security. Socio economic status of the farmers has been found one of the main factors for enhancing production and productivity of farm produce in India. In this direction, present survey was conducted in the year 2016 in three districts viz. Kathua, Udhampur and Rajouri of Jammu division which were purposively selected based on potentiality for more cocoon production and having maximum number of beneficiaries. A survey was conducted to know the current position of silkworm rearers and to understand their socio-economic profiles and to evaluate participation of the respondents in sericulture with respect to age, caste and economic status. Chi-square (χ2) value (23.78**) revealed highly significant association of age with respect to districts. Highly significant (23.78**) association of age and caste (37.33**) was found in all the districts. Majority of the farmers belonging to middle age group showed highly significant results and indicated the need for popularization of this avocation among the unemployed youth.

Abstract
Saussurea costus (Falc.) Lipsch., is an imperative medicinal plant species growing in Kashmir Himalaya. S. costus is used in the treatment of countless infirmities. The underground portion of this plant species encloses various sesquiterpene lacones such as costunolide, dehydrocostus lactone and many others which can be developed as bioactive molecules. It is enlisted in Appendix Ist of Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). During the present study, different explants viz. leaf, petiole, pedicel, etc. of S. costus, were subjected to in-vitro studies so as to develop proficient protocols for its regeneration. In addition to this, seed germination was also achieved by giving different treatments. Leaf explants produced maximum amount of callus on Murashige and Skoog’s (MS) medium supplemented with 6- Benzylamino purine (BAP) (2.5 mg/l) in 90% cultures within 14 days. MS medium containing BAP (2.5 mg/l) was the most effective medium for shoot regeneration. Petiole and pedicel also showed callus formation and shoot regeneration but number of days taken was more and percent culture response was less. The in vitro regenerated shoots from leaf explants also develop roots on MS basal medium within a period of 15 days.

Abstract
In this research heavy metal stress tolerance capacity of Impatiens balsamina L. was assessed. Here, two different approaches in-vitro and in-vivo were used for the production of plantlets. In-vitro approach involved tissue culture approach and in-vivo direct through media (soil, cocopeat, mosses). Seeds were used for the production of plantlets. After 30 days of seedlings development all the plantlets which are produced through in-vitro and in-vivo approaches and plants were transplanted in the pots and treated with two metals Lead and Cadmium in the form of Pb (NO3)2 and Cd (NO3)2. Different concentrations were selected for Lead 200mg, 400mg, 600mg, 800mg/Kg and for Cadmium 5mg, 10mg, 15mg, and 20mg/Kg. Each pot was filled with 5Kg of soil. The metals were given directly through root zone of plants in solution form. After incubation time of 75 days mature and treated plants were collected and root length, shoot length, number of branches was measured scientifically. On the basis of the results obtained of physiological parameters of the plants we concluded that for both the metals in-vitro produced plants has more capacity to tolerate the metal stress as compare to in-vivo produced plants.

Abstract
The present study is the first effort to describe diversity and molecular phylogeny of moths from Marathawada region of Maharashtra. A total 55 moth specimens were collected and sequenced from different sampling stations across the region. Our 47 sequences matched with COI sequences already deposited with BOLD. But, 4 sequences did not match with any species but correctly matched with deposited sequences of genus. Our 4 sequences are new record to BOLD but correctly matched with NCBI database. Nearest neighbor distances were greater than 3% for all the species but for two pair of specimens: 1) Agrotis ipsilon (EDBLM004/EDBLM005) vs Agrotis munda (EDBLM034) it was 2.8, Agrotis munda (EDBLM035) vs Agrotis ipsilon (EDBLM005) it was 2.8. The largest nearest neighboring distance of 14.47% was observed in Hydrilodes metisalis vs Agrotis munda. In present study, we have produced DNA sequences for 21 moth species from Marathwada region of Maharashtra, which may help future conservation efforts and in construction of DNA library of moth species from here.

Abstract
Banana is used widely because of its nutritional values. In the past, some studies show yellow banana peel (Musa acuminata) parts, and their fruits can be used to treat human diseases. Banana is a part of banana peel that also has antibacterial activity and antifungal activity against microorganisms but has not been studied extensively. Since, there are studies that relate the phytochemical analysis of qualitative, quantitative analysis, and microbial activity of antibacterial, antifungal activity of yellow banana peel against periodontal pathogens. Hence, this study aims to determine the phytochemical analysis and antimicrobial activity in methanol extract of yellow banana peel (Musa acuminata). The phytochemical result showed methanol to be a better solvent for the extraction of the bioactive agents in banana peels which include: alkaloids, flavonoids, saponins, tannins carbohydrate are (+) reaction but phenol and protein are (-) reaction. Antimicrobial activity both are activated against the gram-positive, gram-negative bacterial but maximum activity of antifungal.

Abstract
A large part of reclaimed wetland in the Eastern fringe of Kolkata is being used for maize farming. Fungicides are frequently being used by maize growers. Leaf blight is a common disease of maize in this area which is caused by Exserohilum turcicum. Inhibited growth response of the pathogen was noted in-vitro when fungicides namely Chlorothalonil and Mancozeb were added the basal medium. Field experiment showed that the foliar spray of those two fungicides significantly controlled the disease intensity of maize leaf blight. Mancozeb was found to be most effective at 100 and 1500 μg/ml for selected and recommended doses respectively in field condition.

Abstract
Liver diseases are the most common ailment all over the world mostly caused by viruses, toxic chemicals, excessive intake of alcohol, high doses of paracetamol, carbon tetrachloride, and chemotherapeutic agents, etc. Paracetamol poisoning is the most common cause of acute liver failure in the developed world. In the traditional healthcare system, it has been used in the treatment of anti-diabetic, antioxidant, anti-asthmatic and wound healing activities. The hepatoprotective effects of ethanolic extract of Mimosa Acalypha indica against paracetamol-induced liver injury in experimental rats. Liver injury induced by a single dose of paracetamol (100 mg/kg b.w.) in male Wistar rats. Paracetamol intoxication led to a significant increase in the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) and decrease in the levels enzymatic and nonenzymatic antioxidants and histopathological changes in liver tissues were studied. Orally pretreatment with Acalypha indica (10 mg/kg/b.w) daily for 7 days significantly diminished. The present study observed that increased levels of serum AST, ALT, and ALP, attenuated the oxidative stress through restored the levels of enzymatic and nonenzymatic antioxidants. Histopathological examination of the liver tissues of control and treated groups also confirmed the hepatoprotective activity. This exclusivity and dearth of any noticeable adverse efficacy propose the opportunity of using Acalypha indica as used in an efficient adjuvant in the treatment of liver damage.

Abstract
A study was conducted to ascertain the knowledge and adoption levels and their co-relationship with ten socio-economic factors of chawki rearing centre (CRC) entrepreneurs in 22 improved mulberry leaf production technologies. The data was collected from 100 CRCs of six traditional sericultural districts of Karnataka, analyzed using percentages, correlation and regression values and compared brushing capacity-wise. The overall percentages of full knowledge (80%) and adoption (67%) levels were higher in all the CRCs and found to increase with brushing capacity. The entrepreneurs had very high knowledge and adoption levels in improved mulberry varieties and quantity of organic manure application and least awareness and adoption in ‘type of chemical fertilizer and biofertilizer usage. The correlation of socio-economic factors with adoption and knowledge indices were almost similar. The variables such as age, family members, land holding, occupation and experience have expressed weak negative correlation with knowledge and adoption indices. While, education, CRC building ownership, CRC attached with or without grainage were found to have significant contribution in improving the technology adoption and knowledge. Higher R-squared values of regression analysis indicated that middle adulthood, educated and experienced entrepreneurs are involved in the CRCs having higher brushing capacity in traditional sericultural districts of Karnataka.

Abstract
In this science driven world, digital advancement is playing a critical role. However, there is still no substitute for traditional sciences like agriculture and its allied fields like home science. With the advancement in education sector, there is declining enrolment rate in Home / Community and Agriculture Sciences. So, there arises the need to popularize the subject and find out the influencing agents that have an impact on the enrolment rate. In this direction, the present research (conducted under the ICAR funded extramural project) was carried out purposively in Jaipur city of Rajasthan state where information pertaining to influencing agents of high school students was gathered through a structured interview schedule. The total sample size for the study was of 280 high school students, randomly selected from the city. Results showed that due to insufficient awareness, majority of the students did not have any information regarding the career options in Home / Community and Agriculture sciences leading to decline in enrolment rate. Furthermore, the results also revealed that very few of the students had knowledge about the respective departments in Home / Community and Agriculture sciences and its related job avenues. The study concluded that lack of awareness about the sub streams and career scope of Home / Community and Agriculture sciences among high school students is a big reason for depreciating number of enrolments in these areas at college level.

Abstract
Department of Chemistry, Karam Kshetra Post Graduate College, Etawah - 206 001, Uttar Pradesh, India The official International Commission for Uniform Methods of Sugar Analysis for conductivity ash determination in sugar product by ashing of sugar is in practice. Simple, rapid methods are needed for the determination of purity of sugar products that may contain electrolytes and non-sugars. Using conductometric studies of cane juice and cane sugar systems shows that the conductivity is linear with the electrolytes and non-sugar present in both cane juice of 20% v/v as well as in cane sugar over the range of 0 to 20% w/v. With present method linearity can be approached more nearly by increasing non sugars concentration, but a parallel decree in sucrose purity. Another observation comes out from acidity measurement of cane juice increases 0.1%, whereas, increase in conductivity value is around 11%, indicating conductivity is more informative, precise, and controlling parameter than conventional acidity parameter. Percent reflectance values of sugar were also taken and compare with conductivity data for quality assurance of cane sugar.

Abstract
Women empowerment refers to the creation of an environment for women where they can make decisions of their own for their personal benefits as well as for their society. Self-help groups are becoming one of the important means for the empowerment of poor women in almost all the developing countries including India. ‘Kudumbashree’ meaning prosperity of the family, is the state poverty eradication programme initiated by the Government of Kerala for derooting the absolute poverty from the state. It is a holistic, participatory, women oriented innovative poverty-reduction approach. ‘Kudumbashree’ initiated by the government of Kerala has proved that women empowerment is the best strategy for poverty eradication. ‘Kudumbashree’ has become the lifeline to many of the poor women in the state of Kerala. Resultantly, the women of the state have become active participants in the planning and implementation process of various anti-poverty programmes. By participating in various income generating cum developmental activities, the morale and confidence of women becomes very high. The present study was conducted in six selected villages of Alappuzha District of Kerala State with a sample size of 120 women respondents. ‘Eco-friendly group farming’, ‘Terrace cultivation’, ‘Tailoring’, ‘Organic farming’, ‘Coir making’, ‘Banana chips making’ and ‘Mushroom cultivation’ were found to be the major entrepreneurial activities of women which empower the rural women.

Abstract
To satisfy the need of growing population, it is high time to focus maximum yield. This is only possible if plants get sufficient nutrient for growth. Plant nutrient content is neglected many times, though it should be given the importance. This paper emphasizes the identification of macro- nutrient content using image processing and machine learning techniques. This will help farmers to get the idea about the health of their crops and the preventive measures to be taken. Also, this will be helpful in vertical farms where nutrient supplements are provided to plants. This project also helping farmers to identify the nutrition deficient plants in large scale using aerial vehicle (quadcopter). Plants need sufficient amount of nutrients for complete and healthy life-cycle. Sufficient amount of six macro-nutrients like Nitrogen, Phosphorous, Potassium, Sulphur, Magnesium are more important for the normal and healthy growth of plants. Lack or absence of nutrients leads to difficulties in carrying the life cycle of a plants and ultimately affect the maximum yield. Thus, it is necessary to have timely and daily check for nutrients contents which plays a major role for yield. Plants usually show the definite deficiency on their leaves with notable different patterns and structures for each nutrient. Our proposed work is to provide a computerized and reliable solution for nutrient deficiency identification. An unmanned aerial vehicle (UAV) used to help optimize agriculture operations, monitor crop growth, and increase the yield. UAV let farmers see their fields from the sky. The top view which we obtained can reveal many issues such as irrigation problems, soil variation, pest and fungal infestations.

Abstract
An experiment was conducted at the Agronomy Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner during Kharif 2017 on loamy sand soil. In reference to the objectives the effect of different dates of sowing and different varieties on yield and quality parameters of sesame. The experiment comprising total 16 treatment combinations; four date of sowing (10 July, 20 July 30 July and 09 August) & four varieties (RT-125, RT- 46, RT- 127 and RT- 346) in split plot design with three replications. The results revealed that nitrogen and phosphorus content and uptake, crude protein content, oil content, and oil yield was influenced significantly with different sowing dates. Sowing on 09 August recorded significantly higher nitrogen (2.45%), phosphorus (0.53%) and crude protein (15.32%) content in seed as compared to 10 July, 20 July and 30 July. Whereas, sowing on 10 July recorded higher nitrogen (17.20 kg/ha), phosphorus (3.91 kg/ha) uptake, oil content (46.11%) and oil yield (399 kg/ha). In the case of varieties, the nitrogen, phosphorus uptake and oil yield also influenced significantly. Variety RT-125 have significantly higher nitrogen (13.66 kg/ha), phosphorus (3.0 kg/ha) uptake and oil yield (299 kg/ha) as compared to variety RT-46, RT-127 and RT-346. The crop was sown on 10 July overall better than other dates of sowing it was recorded significantly higher nitrogen, phosphorus uptake, oil content and oil yield seed, straw yield, biological yield and harvest index of all tested varieties of sesame. The crop sown on 09 August recorded significantly higher nitrogen and phosphorus and crude protein in seed content as compared to 10 July, 30 July and 30 July, respectively. The maximum seed yield, nitrogen & phosphorus uptake, oil content and oil yield was recorded by variety RT- 125 and nitrogen, phosphorus and crude protein content higher in RT- 46. Also, variety RT-346 recorded higher straw and biological yield as compared to varieties RT-125, RT-46 and RT-127. These finding was only one-year experimental data so it is required further experimentation to arrive at some more consistent and final conclusion.

Abstract
Foxglove or tilpushpi, botanically known as Digitalis purpurea L. is medicinally and economically important plant species due to the presence of cardiac glycosides used in life-saving medicines. In the present study, different concentrations of bijamrita (25%, 50%, 75%, and 100%) on seed germination were tested in Petri dish as well as paper towel method. It was found that per cent germination and mean daily germination was highest in 75% concentration of bijamrita in Petri dish while speed of germination was found highest in 75% treatment in paper towel. Lowest values were found in both the controls. Mean germination time was highest in 50% and 75% in petridish and paper towel respectively in comparison to both the controls. In Petri dish method peak, value was found highest for 100% and lowest for 50% concentration of bijamrita and germination value was observed highest for 100% and lowest for 25% concentration of bijamrita. Peak value and germination values were found highest in 75% concentration of bijamrita and lowest in control of paper towel method. Seedling vigor index I and seedling vigor index II were recorded highest in seed treated with 100% Bijamrita. Bijamrita being an organic treatment mixture, prepared from locally available materials, easy to prepare and apply with minimum or no harmful effect on the propagating material. The present results indicate that higher concentration of bijamrita is helpful in increasing germination percentage. Therefore, it may helpful in increasing germination of other medicinal plants which will help the farmer in getting maximum returns. Therefore, it can be recommended for the seed treatment of agricultural as well as horticultural crops and a consequent reduced dependency over chemicals. Further studies can be extended to find out its effect on other methods of propagation such as, cuttings, grafts, buds, and other vegetative propagating materials.

Abstract
The present investigation was undertaken to study existing genetic variability in 50 seedling mango germplasm, locally available at north western India especially in Punjab, Haryana, Himachal Pradesh and Jammu and Kashmir, during the period 2016 to 2019. Genetic variability study through phenotypic and genotypic coefficient of variations revealed that most of the quantitative traits under present study exhibited almost equal magnitude of phenotypic as well as genotypic coefficient of variations. Hence, most of the quantitative traits of mango accessions in the present study were considered comparatively stable in nature. The greater genetic advance were noticed for canopy volume, tree spread, hermaphrodite flower percentage in the inflorescence, sex ratio (M/H), fruit weight, TSS : acid ratio, reducing sugar content, yield per tree, incidence of floral malformation, anthracnose, powdery mildew, and attack of scale insect per leaf and mealy bug per twig, which revealed that these characters had an additive gene effect and therefore, have more role in proficient selection. These outcomes may prove very much useful to chalk out future breeding strategy with the same gene pool and also in possibility of recombination of effective new traits with the existing genetic resource of seedling mango germplasm in the states of Punjab, Haryana, Himachal Pradesh and Jammu.

Abstract
Multiple applications of nanoparticles in aquaculture practices are witnessed in many studies. Long term effects of these nanoparticles are yet to be determined for its safe utilization in various aspects of aquaculture. It is important to conduct toxicity test of the nanoparticles before introducing to the crop including fish. Measurement of dose and concentration of nanoparticles are also equally important. Among the methods employed, green' synthetic methods are to be used as it is an environmentally friendly and biologically safe method. It will also help to retain the bio-efficacy of the synthesized nanoparticles. However more researches are needed to eliminate the present dilemma regarding the rational use of nanoparticles in aquaculture.
