This study was performed to determine the assosiation between seventeen agronomic traits of three Fpopulation viz;Dhanrashi x Wita-12, Dhanrashi x Shyamala and Sahbhagidhan x 2Birsamati in riceat Birsa Agricultural University , Kanke, Ranchi, Jharkand in 2019. Sixteen characters were assessed in this study viz days to flowering, plant height, panicles per plant, panicle length, primary branches per panicle, secondary branches per panicle, spikelets per panicle, grains per panicle, 100 grain weight, total yield per plant, grain yield per plant, unfilled grains per plant, grains per plant, spikelets per plant, grain length and grain breadth. Results showed that all the characters except days to flowering and 100 grain weight were positively and significantly correlated with grain yield per plant and grains per panicle in all F2 populations. grain yield per plant was negatively and less assosiated with grain length and L/B ratio in both Dhanrashi x Wita-12and Sahbhagidhan x Birsamatiwhere as in Dhanrashi x Shyamalagrain yield is negatively associated with only L/B ratio.
本研究于2019年在贾坎德邦兰齐坎克的比尔萨农业大学进行，旨在确定三个f群体(即Dhanrashi x Wita-12、Dhanrashi x Shyamala和Sahbhagidhan x 2Birsamati) 17个农艺性状之间的相关性。本研究评价了16个性状:开花日数、株高、单株穗数、穗长、每穗一次分枝、每穗二次分枝、每穗粒数、每穗粒数、百粒重、单株总产量、单株粒数、单株未灌浆粒数、单株粒数、单株穗数、单株穗数、籽粒数、粒长、粒宽。结果表明，除开花期和百粒重外，其余性状均与单株粒产量和穗粒数呈极显著正相关。单株产量在Dhanrashi x wita -12和Sahbhagidhan x birsamati中与粒长和L/B比呈负相关，而在Dhanrashi x Shyamalagrain中，单株产量仅与L/B比呈负相关。

Climate change is one of the burdensome factors of agricultural productivity. Adverse biotic and abiotic stress impacts directly on plants resulting in poor productivity and yield loss. Modern protocols in genome editing using CRISPR, TALENs, ZFNs and Meganucleases enable editing at the precise site. The versatility of genome editing tools makes its application useful in fields like crop improvement, gene functional analyses, pathway research, studying animal models, genetic analyses, epigenetic research, drug development and biofuels research etc. The technological advancements in genome editing are adopted in both monocots and dicots for crop improvement. These technologies are precise, independent of breeding limitations like unexplored germplasm resources and reduce breeding cycles drastically from decades to years to meet the global requirements. The application of genome editing in agriculture proves to be a potential source for developing crops with biotic and abiotic stress, improved yield with better nutritional qualities.

Saurashtra region is characterized by high temporal and spatial rainfall fluctuations. The daily maximum rainfall has a direct impact on the agricultural yield. It is thereby necessary to comprehend the trend changes in the annual daily maximum rainfall (ADMR). The daily rainfall data of 40 years (1981 to 2020), for 11 stations in Saurashtra was utilized for trend analysis of ADMRusing Mann Kendall's method and Sen's slope method. It was revealed from the Mann-Kendall test that significant positive trends were exhibited at Dwarka and Surendranagar. Further, Sen's slope and linear regression indicated that the ADMRat Rajkot and Surendranagar were having highest increasing trend. Trend analysis of ADMRcontribution to annual rainfall showed negative trend indicating better temporal distribution of rainfall. It was also revealed that the extreme events of rainfall usually occurred uniformly on certain days of the year from the results of directional statistics.

Problems of onion crop production and their solutions at farming situations were studies with participation of farmers. In this regard, demonstrations on integrated crop management in onion varieties were conducted in 2017-18 during Rabi season by National Horticultural Research and Development Foundation – Patna under National Horticulture Mission, in differentlocationsofBiharthrough(TDTD)TechnologyDisseminationthroughDemonstration at selected farmers' fields. These demonstrations focused on increase productivity/ net returns of onion per unit area and get the feedback from farmers on the performance of onion varieties. The vigour of the variety is one of the major constraints in production of onion. The productivity and economic returns of onion in improved technologies were calculated and compared with the corresponding farmer's practices. All the five varieties recorded higher gross return, net return and cost benefit ratio in improved technologies as compared to the control plots as well as suksagar variety. It was found that farmers were using old varieties of onion crop without proper use of recommended scientific package of practices. Results obtained showed that over the year NHRDF Red-3 variety performed superior over local check. The gross returns Rs 2,95,502.50/ha, net returns Rs 2,10,227.50 /ha, extension gap ( 146.90 Q/ha) and C:B ratio 3.47were also recorded highest in NHRDF Red-3 variety compared to local variety. Technology gap was highest in NHRDF Red-4(92.84 Q/ha), whereas technology index were minimum in improved variety NHRDF Red-2 12.87% which is at par 13.09% in NHRDF Red-3 compared to local check.

Plant growth is adversely affected by salt deposition in the root zone and requires judicious irrigation water management for enhancing productivity in an irrigated saline environment. To study the salt deposition and subsequent leaching of salts below the root zone of wheat, an experiment with four wheat cultivars (viz. three salt-tolerant KRL-210 (V), KRL-1-4 (V), and 12one salt non-tolerant HD- 2894 (V) were taken for the experiment under artificially prepared 4-1-1-1irrigation water with salinity levels of 4 dS m(S), 8 dS m(S) and 12 dS m(S) besides the 234-1varying salinity of the groundwater from 1.45 to 1.7 dS m(S) during rabiseasons of 2009-10 and 12010-11 at the research farm of Indian Agricultural Research Institute (IARI), New Delhi, India. -1 The soil salinity (EC) was 0.2 dS mbefore the conduction of the experiment during rabi 2009-1:2-1 10 and varied from 0.26 to 0.95 dS mduring rabi2010-11. The total salt-induced in soil was 70.15 -1-1 t haand 55.6 t hafor rabi2009-10 and 2010-11 respectively by saline irrigation water. The salt -1deposition in the crop root zone was observed at maximum (i.e., 17.04 and 22.97 t ha during rabi2009-10 and 2010-11, respectively) for Streated plots and minimum in Streatment levels. 41The production functions for wheat varieties were developed and the coefficient of 2determination (R) was 0.98 to 0.99 and 0.94 for salt-tolerant and salt non-tolerant varieties, respectively. Moreover, it was also estimated that the maximum salt was deposited on the top soil layer (15cm) and the leaching of salts from S, S, Sand Streatments levels was 65%, 63%, 123,452%, and 48% salts, respectively from the root zone. However, this study would assist in the computation of leaching requirements for enhancing productivity in irrigated saline environments.

Beetroot and beet juice have been known for their antioxidant, anticancer and anti-diabetic effects as well as being a source of dietary nutrients that reduce blood pressure and may improve athletic performance. Now-a-days, there is an increased interest in fruits and vegetables processing by products due to their nutritive value. The experiment consisted of various combination of sugar syrup temperature (40, 50 and 60°C), concentration (50, 60 and 70°Brix) and duration of osmosis (60,120 and 180 min) for preparation of beetroot tutti-frutti. The results indicated that the quality observations affected by various treatments. As the temperature and concentration of the solution were increased the water loss and sugar gain was also increased with increase in time. The optimized process parameters for osmotic oodehydration of beetroot cubes were found to be at 62Brix syrup concentration, 50C syrup temperature and 105 min duration of osmosis. The predicted water loss (maximum) and sugar gain (targeted) was 36.12 and 9.80 per cent, respectively at optimized input parameters on the basis of sensory evaluation, texture and overall acceptability.

Among cool season pulses, chickpea and lentil account for over 74% and 79%, respectively of the total area and production under Rabipulses in India. The climate change has resulted in contraction of cool season duration, and as a result, terminal heat stress and root diseases complex are constraining the productivity of both chickpea and lentil. This has necessitated breeding novel genotypes with unique adaptive features to combat the adverse impacts of climate change. Two crosses (BGD 9971 × IPCK 2002-29 and BGD 9971 × JG 16) of chickpea were advanced to succeeding generations commencing from 2014-15. In Fgeneration, one F(BGD 119971 × IPCK 2002-29) showed only partial dominance of non-determinate (NDT) growth habit (of IPCK 2002-29) over the determinate (DT) habit (of BGD 9971). However, the second cross (BGD 9971 × JG 16) indicated complete dominance of NDT (JG 16) over the DT type (BG 9971); the Fgeneration showed a 15 (NDT):1 (DT) ratio, showing duplicate gene action for growth 2habit in chickpea. The same was confirmed in the randomly selected Fprogenies also. During 32018-19, a total of 4 DT Fprogenies derived from the cross (BGD 9971 × IPCK 2002-29) were 6 grown and assessed in preliminary trial for yield and other attributes. Based on their performance over the check (IPCK 2002-29), two superior lines, viz. RCECK 17-2 and RCECK 17-4, were selected for further evaluation. The 'RCECK 19-4' significantly outyielded (1852 kg/ha) the check 'IPCK 2002-29' (1513 kg/ha). In lentil, a segregating population derived from a cross (ILWL118 × DPL58) was also advanced, and 16 single plant selections (SPS) were performed based on biomass, earliness and no. of pods. Further selections in succeeding generations resulted in the identification of a super early genotype 'RCEL19-1' in the year 2019-20. Besides super earliness, this genotype when evaluated in wilt-sick nursery showed greater mortality than the susceptible check 'Seohore 74-3', making it a suitable susceptible check for assessing wilt reaction of test genotypes in the pathological trials. These two novel genotypes, viz. 'RCECK 17-4' (chickpea) and 'RCEL19-1' (lentil), hold promise to be registered as useful genetic stocks for further utilization in breeding programmes.

Agricultural officers were the grass root level workers who worked directly with the farmers in implementing the development activities. Competency and satisfaction of them on their job makes all the difference in smooth functioning of the development initiatives. Problems encountered by them need to be revised according to the suggestions given by them for successful implementation of the extension delivery system. The present study was conducted in 3 districts of Andhrapradesh viz., Chittoor, Cuddapah and Nellore with 90 sample size following ex-post facto research design. Political interference, farmers' interest in subsidies rather than technology and no proper office facilities were the major problems experienced by the agricultural officers which affected their competence and satisfaction levels. Suggestions offered by them to improve their competency and satisfaction were good audio-visual aids, conveyance facilities and good working environment and office facilities.

Pigeonpea is very sensitive to waterlogging. At pan India level, approximately 25-30 per cent area of pigeonpea is prone to excess moisture stress. Atotal of 63 germplasms/genotypes were evaluated along with IPAC-79 as the waterlogging tolerant check under controlled partial submergence condition and under waterlogged field condition for selection of waterlogging tolerant pigeonpea lines. Data were recorded for survivability, days to anthesis, per plant seed yield and maturity period. Pigeonpea genotypes ICARPP01, ICARPP02 and ICARPP03 were found promising. ICARPP01 produced highest biomass per plant (746.5g), pods/plant (924.6) and seed yield per plant (151g). The genotype ICARPP01 took minimum number of days for anthesis (124 days) and maturity (197days), whereas the check variety IPAC-79 recorded maximum number of days to anthesis (201 days) and maturity (255 days).

Drones are unmanned aircrafts that are sent by a pilot on the ground to perform a task with a remote control or that are automatically flown by loading a previously made flight program. The applications of drone technology in the agriculture are addressed in this paper. This technology has broad scope in various fields such as managing water in agricultural systems, water stress detection, disease and pest detection, yield/maturity estimation, weed flora detection, monitoring of workforce, maintaining the livestock and concern logistics. It saves operating time, work accuracy, input costs such as land, water, seed and agro-chemical, and workforce in agriculture.
