Abstract
Current study, investigated the adverse effects of drought stress on growth and modulation of root system architecture of rice inoculated with drought-tolerant Bacillus megaterium. Polyethylene glycol (PEG) solutions of different concentrations (5%, 10%, 15%, 20%, 25% and 30%) were used for drought stress induction artificially. It was observed that growth of bacteria significantly reduced under drought stress, while maximum reduction was caused by PEG (30%) applied. Drought-tolerant Bacillus megaterium identified based on 16S rDNA gene sequence was used to study the effect on drought stress tolerance of rice growth and its root system architecture (RSA). Rice plants inoculated with Bacillus megaterium showed potential to withstand the drought upto 25% of PEG, also increased the plant shoot and root length when compared to control. The bacterium also improved the germination percentage of rice seeds at different concentration of PEG 6000. In vitro grown rice seedlings (cultivar Co51) were inoculated with Bacillus megaterium. After 15th day, changes in the root system architecture were observed using non-destructive root imaging and analysis platform (GIARoot software). The images captured by high-resolution camera were analyzed for twenty different RSA traits by GIARoot software. Among the RSA-variables, maximum number of roots, median number of roots, root network connecting components, network bushiness and solidity, network width and perimeter, total network area, volume and width to depth ratio significantly increased due to drought-tolerant Bacillus megaterium inoculation as compared to uninoculated control. Current investigation concluded that application of Bacillus megaterium may increase the tolerance capacity of crop plants especially rice against drought.

Abstract
The field experiment was carried out at the Instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal, during the year of 2012-13 and 2013-14 in rabi season after harvesting kharif rice for system productivity. Experiment was laid out in a split plot design. The main plot treatment has five numbers of dates of sowing, like 1st November (D1), 10th November (D2), 20th November (D3), 30th November (D4) and 10th December (D5). The sub plot treatment has five nos. of cultivars, like B-9 (Benoy) (V1), Jhumka (V2), Panchali (V3), NRCHB-101 (V4) and NRCDR-02 (V5). The treatments were replicated thrice. The crop management practices were optimum and a uniform dose of recommended N:P:K @ 80:40:40 kg ha-1 was applied in all the plots. Maximum of grain yield was obtained on November 10 because it caused to increase no of siliqua m-1, siliqua length (cm), siliqua plant-1 and grains no per siliqua. Highest yield and yield components were obtained in 10th November and NRCHB-101 was superior in many traits. This system achieved a yield of 8141 and 8935 kg ha-1 of total system yield in year 2012-13 and 2013-14, respectively. It was pragmatic from the results that sowing of rapeseed-mustard on 10th November recorded significantly maximum oil yield as compared to other dates of sowing and sowing on 10th December presented the lowest oil yield. Among the varieties, NRCHB-101 recorded higher oil yield as compared to other four cultivars. Thus, it can be suggested that the cultivar NRCHB-101 and combination with second date of sowing, i.e. 10th November may be recommended for cultivation of rapeseed mustarded for better seed yield and oil yield performance.

Abstract
Present study deliberated some of the straightforward findings from real ground investigations by growing tomatoes under farmers conditions in a tribal dominated landscape of western India. Results obtained persisted well beyond controlled lab/field situations, offering quantified positive influences of drip-based applications to attain better quality tomato fruits and higher marketable yields, even with a curtailed volume of irrigation water in different proportions. Treatments were intended to meet irrigation water requirement (IWR) of crop at pre-identified time gaps and in accordance to daily observed values of evapotranspiration (ETc) and cumulative pan evaporation (CPE). It included criterion having water supplies @ 0.6 ETc, @ 0.8 ETc and @ 1.0 ETc in drip irrigated tomato; while @1.2 IWR/CPE ratio for furrow irrigated crop. Study deliberated preliminary results on variability in magnitudes and outlines of irrigation water movements, wetting patterns, application uniformities, water use efficiencies, qualitative and quantitative attributes of tomatoes, gross marketable yields, and net water savings across drip and furrow-based irrigation systems/schedules. Considerable water savings (45 to 67%), enhanced water use efficiencies (WUE) in drip-based irrigation (47 to 51 in contrast to 18 kg/ha-mm of furrow based), and higher marketable yields (13750 to 19802 kg/ha) with better quality fruits remains the prime achievements. Plentiful food for thought is offered for futuristic RandD for inclusion of sophisticated tools/technologies for transforming present day’s elegant irrigation into a smart irrigation with bits of intelligence, cutting across growing sciences (electronics, computers, ITandICT, artificial intelligence etc).

Abstract
Cut foliages are an important component of the floricultural industry, largely used in decoration as filler in floral compositions. They provide freshness, colour and variety to arrangements and bouquets. Cordyline fruticosa is an important cut green in the world trade and used worldwide for its beautiful foliage. The increasing demand for the production of quality cut foliages pressurizes the flower growers to adopt advanced technologies even under poor resource conditions. Soilless culture is one such production system that involves precise control of nutrition and efficient use of water, which in turn resulted in quality produce commanding premium price in the market. Owing to the above demand, the present investigation was carried out during 2017-18 at Horticultural College and Research Institute, Periyakulam to determine the effect of different nutrient formulations on growth and yield of Cordyline fruticosa grown in soilless culture system. Eight nutrient formulations were tested for its efficacy along with rain water as control and observations on growth and yield parameters were recorded. The results of the study revealed that Hoagland and Arnon- nutrient formulation increased growth and yield parameters of Cordyline fruticosa grown in soilless culture system.

Abstract
The study was conducted from August 2016 to June 2017 in West Bengal. The study was conducted in Nadia and North 24 Parganas districts of West Bengal by drawing a random sample of 120 respondents covering eight villages and four blocks. Milk is highly perishable commodity. Contaminated milk deteriorates quickly and produces diseases if consumed. Therefore, extreme care has to be taken in production, storage and transportation of milk. Data was collected by structured interview schedule. Most of the farmers were having low education status or studied up to lower level and mostly they were from medium to old age group, few farmers were exposed to magazine/bulletin pertaining to clean milk production. All the dairy farmers were having high post test knowledge scores irrespective of their category because of their immediate knowledge gain. Old age group farmers fell in high knowledge retention score category and all the young age group farmers fell in medium knowledge retention score category. Majority of the respondents have not seen any programme on clean milk production. As most of the farmers were having lower level of education, so there was a need to disseminate information through multimedia which could be effective to get desired change irrespective of education status of respondents.

Abstract
Overuse of antibiotics decreases its efficiency to cure disease, thus aggravating the resistance. In this line, one health approach is a step towards antibiotic conservation and sustainability. In present study, an Antibiotic Usage Index was developed with 19 statements after consultation with experts, wherein reliability and validity were ensured for the Index. The primary data were collected from total of 171 farmers comprising of 59, 56 and 57 small, medium and large dairy farmers respectively based on herd size. The data was collected from Karnal and Kurukshetra districts of Eastern Haryana using random stratified sample. The comparative study of the three broad categories of farmers revealed large farmers were judicious to some extent in comparison to small and medium farmers. Results indicated that use of antibiotics in dry cow therapy, teat sealant and probiotics were very less. A chi square statistics was computed on the Antibiotic Usage Index at 5 and 1 percent level of significance. In, which 98 percent responses were found significant at this level of significance. Amongst socio- personal variables, herd size education and milk production were highly associated with the judicious use of antibiotic as the Pearson chi-square value for the test was highly significant.

Abstract
India being the largest producer of coriander seed in the world. India exports around 40000 tonnes of coriander either in the form of whole seed or in powdered form. Compound growth rate (CGR) was used for analyzing the growth in black Coriander area, production, yield, export quantity, unit value and export value over the years. The results indicated that the growth in area under coriander was found to be meager, while production and productivity showed positive and significant growth. Since the area under coriander is showing a decreasing trend over the years, emphasis should be given for promotional programmes to augment the area. The influence of area and export price on the changes in production of coriander was found to be positive, but the influence of domestic price was found to be negative. The export growth of coriander in terms of quantity and value was found to be positive and significant. The Markov chain analysis revealed that Malaysia, United Arab Emirates and Singapore were found to be the loyal markets for Indian coriander. The increasing share of other countries clearly showed that the need to explore and exploit the market potential of other countries. Efforts are also needed to improve the efficiency of production to make the product acceptable and price competitive in other importing countries. This will facilitate in creating more exportable surplus and hence to take price advantage in the international market under the WTO trade liberalization regime.

Abstract
Spirulina platensis and sea weeds are algae which have high macro and micro nutrients and beneficial chemicals. The present study is proposed to harness the potential use of Spirulina platensis and sea weeds viz. Sargassum wightii, Sargassum myricocystum and Turbinaria conoides extracts towards improvement of quality and storage capacity of blackgram seeds. The seeds of blackgram cv CO 6 were subjected to various treatments viz. T1- Control, T2- hydropriming for 3 hours, T3- priming with 1.0% Sargassum wightii extract for 3 hours, T4- priming with 1.5% Sargassum myricocystum extract for 3 hours, T5- priming with 1.5% Turbinaria conoides extract for 3 hours and T6- priming with 1.5% Spirulina platensis extract for 3 hours. After priming and drying back to original moisture content, the seeds were packed in cloth bags and stored in an ambient environment. The physiological and biochemical seed quality parameters were analysis at bimonthly interval. The results revealed that the seeds primed with Spirulina platensis, Turbinaria conoides and Sargassum wightii extracts maintained seed quality up to 6 months of storage while seeds primed with Sargassum myricocystum extract, hydropriming and control maintained seed vigour only up to 4 months with Indian minimum seed certificate standard (IMSCS). Thus, Spirulina platensis, Turbinaria conoides and Sargassum wightii could be used for seed priming under seed storage of blackgram.

Abstract
Shelf life of packed foods is determined by two main material specifications that is gas transmission rate and water transmission rate. The developed PP and LLDPE nanocomposite films with a combination of compatibilizer (5, 10 and 15%), nanocellulose (2, 4 and 6%) and essential content i.e. cinnamon bark oil and curry leaf oil (1, 2 and 3%) were tested for GTR and WVP. Least values of OTR and CTR rates in LLDPE composite films were found for treatment N (1772 and 3905 cc/m2/day). In PP nanocomposite films, the least GTR values were found in Treatment C (1522 cc/m2/day of O2 and 2425 cc/m2/day of CO2). The reduction in OTR rates was found to be 62 percent in LLDPE nano films and 16 percent in PP nano films. In LLDPE films, WPTR reduced by 49 percent in treatment N compared to control and the same gave least water vapor transmission rates (3.95 g/m2/day). Similarly, in case of polypropylene films, lowest water transmission rate was recorded in treatment C (1.90 g/m2/day).

Abstract
Production of food grain is an easiest practice but keeping the yield corresponding to the seeds sown is the most difficult target in agricultural practices. There are numerous factors that controls the crop yield out of which the weeds affect the yield loss in its extreme level. In this research, to develop a low cost and small size weeder for small and marginal farmers, a rotary power weeder was conceived. The most wearable part, i.e. the blade was designed and simulated using SOLIDWORKS simulation and then developed accordingly. The field evaluation of the machine results viz. weeding index and field capacity were found to be 77.4 percent and 0.1018 ha-h-1, respectively. The unit saves 74.5 per cent of cost and 95 percent of time compared with manual method. The cost of machine is less as compared with other self-propelled weeders and can be easily affordable to small and marginal farmers.

Abstract
A field experiment was conducted in order to determine the irrigation interval based on soil matric head in the crop root zone of a rose plant under surface drip irrigation system. In the present study, irrigation scheduling was done using Tensiometer. Since Rose is a sensitive crop, the irrigation was given, when the soil matric potential exceeds -20 kPa. The irrigation was given based on soil matric head observed in Tensiometer installed at a depth of 30 cm. The model was calibrated and a set of soil hydraulic parameters were optimized. The calibrated model was used to simulate the soil matric head. The simulated soil matric head good agreement with the observed soil matric head. The model performance was evaluated at a depth of 20, 25, and 30 cm depth using root mean square error, mean relative error, mean absolute error, correlation coefficient, and model efficiency. It was found that the root mean square error is 3.17, 3.90 and 3.17 (cm cm-1), average mean relative error is 10.48, 3.46 and 5.49%, mean absolute error is 12.58, 4.10 and 6.08 (cm cm-1), correlation coefficient is 0.90, 0.81 and 0.81, and model efficiency is 99, 98 and 99% for 20, 25, and 30 cm depth respectively. Since the model efficiency is high, the model can be confidently used to simulate the soil matric head for irrigation scheduling of other crops in order to save water. From this study, it was recommended that the optimum irrigation interval of rose planted in sandy loam texture soil was two days.

Abstract
The word ergonomics may seem to be an over or inappropriately used term at times, but the practical reality is that a good understanding of ergonomics and human interaction is a necessity for any successful product. In India, transplanting of the horticultural crop depends on human labour. In changing scenario of agricultural mechanization, ergonomics plays crucial role for effectiveness of the operation. Therefore, the study was undertaken to evaluate the seedlings transplanting operation on ergonomic basis and to work out the energy expenditure rate involved in the operation. Manually operated single row seedling planter was selected for the study and the male and female subjects selected randomly in the age group of 25-35 years operated it. The heart rate (HR) of the subjects was measured by computerized polar heart rate monitor (HRM) and it was taken as a base to work out energy expenditure rate. The field capacity of single row manually operated seedling planter was found to be 0.0166 ha hour-1 while for planting by hand it was found to be 0.0031 ha hour-1. The average energy expenditure for male and female workers for planting operation with seedling planter was found to be 29.08 and 28.26 kJ min-1 and for conventional method of planting it is 29.51 and 28.67 min-1 respectively. The operation was graded as 'heavy work' on the basis of heart rate.

Abstract
Reclamation potential of biochar applied either alone or in combination with gypsum on improving soil Physico-chemical properties and yield of ragi (CO 15) under sodic soil was evaluated in pot study with eight treatments at Anbil Dharmalingam Agricultural College and Research Institute, Trichy. Treatments included biochar at different rates viz. 5, 10 and 20 t/ha with or without gypsum (@ 50% GR) and control. Experiment was conducted in CRD with three replications using sodic sandy clay loam soil. Results showed that the application of various rates of biochar with or without gypsum had a profound influence on reducing the soil pH and ESP and enhancing ragi grain yield. The electrical conductivity and cation exchange capacity were also significantly increased at post harvest stage of crop growth. Application of 50% gypsum plus biochar @ 20 t ha-1 significantly reduced the soil pH (9.16 to 8.33), ESP (29 to 14) and recorded highest grain (8.52 g plant-1) and straw yield. The results of the present investigation clearly indicates that the biochar @ 20 t ha-1 plus 50% GR can be used as an amendment in sodic soil for decreasing the soil sodicity and increasing the yield of ragi when compared to its sole application.

Abstract
In this study, HYDRUS-1D was used to simulate the ponded infiltration through double ring infiltrometers into a hypothetical sandy loam soil. The soil hydraulic parameters were optimized by inverse modeling. The optimized soil hydraulic parameters were residual water content, (θr = 0.0076 cm3 cm-3), saturated water content, (θs = 0.3103 cm3 cm-3), inverse of the air entry value (α = 0.0011 cm-1), parameter n in the soil water retention function (n=1.337), saturated hydraulic conductivity (Ks=0.0238 cm min-1) and pore connectivity parameter, (l=0.0011) respectively. The average saturated hydraulic conductivity for the sandy loam soil under study was found as 0.0238 cm min-1 (34.27 cm day-1) through inverse modeling. The unsaturated hydraulic conductivity was found to be in the range of 0 to 0.063 cm day-1, which is much smaller than saturated hydraulic conductivity. The model performance was evaluated by the root mean square error, correlation coefficient and model efficiency and it was found that 0.003 cm, 0.99 and 0.99 respectively. From the results, it was concluded that the HYDRUS-1D model is a very good tool for simulating water flow as well as optimization of soil hydraulic parameters through an inverse solution.

Abstract
Agricultural subsidies play a vibrant role in the development of the farmers as well as the agriculture sector. Inputs like fertilizers, power, irrigation facilities, seeds, farm implements and credit etc. are provided to farmers at a subsidized rate. Many experts and policy makers believed that the subsidies support to the livelihood of the small and marginal farmers and its withdrawal will lead to their decreased socio-economic status. Hence the research study was carried out to realize the views of small and marginal farmers concerning various aspects of agricultural subsidies in terms of their awareness, opinion and problems. The study utilized primary farm household level data collected in 2018 from randomly selected farm households in Ariyalur district. Findings of the study revealed that 90 per cent of farmers were aware of the subsidies being provided in the areas of seeds, plant protection materials, machinery, micro-irrigation, power and price (MSP). Input dealers and fellow farmers were found to be the most utilized sources by the farmers to get information regarding agricultural subsidies. Age, education, income, credit availability, membership in any organization is the major factors influencing farmers from receiving subsidized inputs. Finally Lengthy documentation procedure, lack of credit, high interest rate on loans, No fixed place of sale of subsidized inputs ,Sub-standard quality of subsidized inputs were found to be the major problems faced by the farmers regarding agricultural subsidies.

Abstract
India is predominantly an agriculture-based country, 57% of its population is dependent on agriculture for their livelihood. But agriculture still contributes only 20% of country’s GDP. This is because of the fact that, in rural population of India, 26% of population still lives BPL. Sericulture being having a unique feature of eradicating rural problems in terms of employment and migration to the cities for want of jobs, has played a vital role. One of the new concepts growing in India is integrated farming for which main component is sericulture. To make sericulture more productive and sustainable the concept of tree mulberry is being popularized in Jammu and Kashmir State in the recent years. In this direction, the present study was conducted on eleven mulberry genotypes viz. English Black, Morus multicaulis, Okinowa, S-1301, Ch. White, Goshoerami, Tr-8, C-763, S-1531, Tr-10, C-4 to study their performance as tree in Jammu and Kashmir. The result revealed that highest leaf yield per hectare was observed in Goshoerami (15 Metric tons) followed by multicaulis (12 Metric tons). However, in terms of early sprouting multicaulis attains 42.27% sprouting as compared to Goshoerami on March 25th where sprouting was seen in the month of April only. Leaf shedding was recorded highest 88.70% in C-4 mulberry variety on November, 30th and least in Goshoerami 65.30%. Advantages over other type of plantation were also observed for the benefit of sericultural farmers.

Abstract
The present investigation conducted during the period from September, 2016 to January, 2017 at the Department of Floriculture and Landscape Architecture, K.N.K. College of Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.). The experiment was laid out in completely randomized design with three replications. Tuberose varieties like Vaibhav, Pearl Doublec, Calcutta Double, JK T- 4, Mexican Single, Shringar, Suvasini, Phule Rajani, Hyderabad Single, and Hyderabad Double was used for the experiment. The varietal difference had significant influence on the vase life parameters and biochemical parameters of tuberose in the present study. Among the varieties studied Suvasini recorded the maximum fresh weight (g) of cut spike during the all stages of observation (at harvest, on 3rd day and 5th day in vase and at senescence). Suvasini recorded the maximum moisture percent of cut spike both at harvest and at senescence. Suvasini recorded the maximum water uptake (ml) in vase during all the stages (on 3rd day and 5th day in vase and at senescence i.e. total water uptake). Suvasini recorded the maximum number of florets per spike, length of florets (cm) and diameter of florets (cm). Suvasini recorded the longest vase life (days) of cut spike.

Abstract
The present research work was conducted in Ranchi district of Jharkhand. In this study possible constraints in awareness, access and utilization of weather information sources were listed and accordingly they were ranked. From the present research conducted, it can be concluded that there are lot many constraints in awareness, access and utilization of weather information sources with each constraint having many other sub domains. Weather information sources are important tools by which many risks in agriculture can be minimized and farmers can get maximized profit. Constraints such as lack of knowledge, interest, and technical knowledge can be addressed by providing them proper training programs regarding importance of weather information sources and their role in agricultural practices. Government and other institutions should facilitate for provision of proper economic means so that they may be able to access these sources easily. Apart from these there may be other constraints in access and utilization of weather information sources which needs to be addressed as soon as possible. As we all know that increase in number of farmers’ suicide is increasing everyday due to lack of proper and timely information, weather updates being one of them. Also there are many farm families who are migrating to different sectors because of livelihood insecurity. These problems need to be addressed as soon as possible with government, private sectors and NGOs being the initiators.

Abstract
The present study aims at storing the jamun seeds a highly recalcitrant species in the refrigerated condition (5℃) to extend the seed longevity. Jamun seeds were stored under ambient and refrigerated condition, and were assessed for their germinability on alternate days. It was noticed that refrigerated jamun seeds maintained 100% germination until 13 days of storage irrespective of the reduction in moisture content but under ambient conditions 80% of seeds remained viable till 7 days with moisture content of 32.5% further reduction in moisture content brought down the germinability to 20%. The results of the study indicate that the storability of recalcitrant seeds can be extended under refrigerated condition and until the presence of critical moisture the seeds are able to germinate and moisture content of 31% may be the critical moisture for storing the jamun seeds. From the above results it can be concluded that jamun seeds can be stored upto 7 days under ambient conditions without reduction in viability beyond which germination get reduced due to reduction in moisture content affecting the seed viability. Jamun seeds when stored under refrigerated conditions extend the seed viability until 13th day by preventing the rapid decline in moisture content from the seeds.

Abstract
The study has examined profitability, productivity improvement and determinants of a new technology-Sustainable Sugarcane Initiatives (SSI) adoption in sugarcane cultivation in Tiruvannamalai district of Tamil Nadu. The data was collected from 120 sugarcane growers during 2017. The ex-post facto research design was used for the study. Although cost of cultivation has been found higher in SSI method than conventional method, the cost of production is lower due to more profitable under SSI method than conventional methods. The subsidy given for adopting the SSI technologies, technological interventions, demonstrations and trainings to farmers on SSI method such as fertigation, wide row spacing, etc. conducted by Department of Agriculture and agricultural scientists, success stories of fellow farmers were the contributing factors for the increased yield and income. Therefore, the study has concluded that sugarcane cultivation is more profitable under SSI than conventional method. It has concluded that SSI is ‘more with less’ technology in term of water and seed and it is positive technology change in terms of human labour, fertilizer and machine labour.

Abstract
Insect pests are major biotic constraints in production throughout the country and mulberry is not an exception. The perennial nature of mulberry combined with monoculture practices, harbors several pests throughout the year with seasonal variation. Over three hundred insects and non-insect species of pests are known to infest mulberry. The pests infesting mulberry are grouped into sap feeders, stem feeders, defoliators and root feeders. Among the sap feeders infesting mulberry, incidence of thrips is the highest. Thrips damage causes loss of moisture from leaves besides causing appreciable reduction in protein and sugar value of leaves. The present review focuses on literature generated on various aspects of thrips viz. seasonal incidence, extent of losses, bio-efficacy of chemicals and non-chemicals.

Abstract
Hydroponics is a science of growing crops without using soil as a base. Usually, soil is considered to give strength and perform as a media for providing nutrients and water to plants. Hydroponics uses water as a medium to provide nutrients to plant artificially and in a controlled manner and is also called as Controlled Environment Agriculture. This study focuses on how we can use hydroponics technique to grow green fodder. Green fodders are staple feed for milk producing animals which leads to increase in quality and quantity of milk. This study indicates that if we can stabilize the availability of green fodder using this technology throughout the year then this can be leading to sustainable dairy farming.

Abstract
Unabated population explosion has created unprecedented pressure on agriculture on one hand and on the other hand the excessive use of chemical fertilizers has also had its impact upon the health of consumers the human beings and other related life forms on earth. Although agriculture has undergone series of advancement since 12th century and is being practiced extensively throughout the world today, yet even after increased health concerns the alternative to the use of chemicals and other pesticides, fungicides or herbicides is not picking upto expected level. In spite of the fact that one third of the world’s workers are employed in the area of agriculture yet full fledged efforts are not in place to make it more and more sustainable. Conventional agriculture continues to be practiced for meeting the food needs of a growing human population, which has led to an increasing dependence on the use of chemical fertilizers and pesticides for increased productivity. One of the alternatives for increasing the crop productivity on sustainable lines is the use of biofertilisers or the microbial inoculants which are essentially live carrier based inoculants proven to reduce the diseases through increased productivity. The use of these biofertilisers of different origins and for different nutrient supplements is not only eco-friendly but environmentally safe and cheap alternatives for increasing agriculture productivity.
