In recent days observed extreme variations in the climate and weather events are increasingly being recognized as key aspects of climate change. ln this study we assessed the spatial-temporal variability of minimum and maximum temperature over the Kalaburgi district of Karnataka, India for the period 1981-2018, using gridded data with 0.5-degree resolution obtained from National Aeronautics and Space Administration prediction of worldwide energy resource (NASA POWER) project. Trend detection and quantification in the temperature evaluated using the non-parametric Mann-Kendall (MK) test and Sen’s slope estimator. The overall average of minimum and maximum temperature data and Sen,s estimate showed the increasing trend in series for the last 38 years. The highest average minimum temperature observed is densly distributed over the Jewargi with a range of 24.74 0C to 26.68 0C and all other places found sparsely distributed with range 19.98 0C to 23.50 0C. ln the overall, the spatial distribution analysis results observed the densely distribution of maximum temperature in AIand, Afzalpur, Jewargi and part of Kalaburgi with range of 32.88 0C to 33.99 0C. The average maximum temperature exhibited the increasing trend linearly and Sen's slope also estimated increasing trend in the study area.

A field experiment was conducted at Agriculture Research farm of Chaudhary Chhotu Ram(PG) College Muzaffarnagar during summer season of 2019 and 2020 to evaluate the Integrated Nutrient management on growth, yield and quality of summer cowpea (Vigna unguiculata (L) Walp.) under Doab region of Uttar Pradesh. There were sixteen treatments combinations with four fertility levels (Control - F0, 50% RDF - F1, 75% RDF - F2 and 100% RDF - F3) and bio - organics (control - B0, PSB - B1, Vermicompost @2t/ha - B2 and B1+B2 = B3) and tested in a Randomized block Design with three replication. The recommended dose of fertilizer (RDF) was considered as 20 kg N, 40 kg P2O5 and 40 kg K2O/ha. Results indicated that application of 75% RDF - F2 being at bar with that of 100% RDF (F3) but significantly superior in respect to all the growth as well as yield and yield attributes to other treatments tested in study. Further analysis of data clearly indicate that application of vermicompost @2t/ha being at per with PSB + Vermicompost, but superior to other treatments. Combined application of 75% RDF and Vermicompost @2t/ha (F2B2) proved to be the best treatment in terms of pod / plant, seed yield and N uptake as well as protein production. Net return work out of different treatment combination in this study is also witness this fact.

Good quality healthy seedlings are very much needed for getting bumper yield and higher returns in vegetable production. Farm women often reported problems in quality nursery production during Kharif season. The high mortality of vegetable seedling results in huge losses of farm women. Keeping these facts in mind JNKVV Krishi Vigyan Kendra Shahdol conducted FLD on income enhancement of Farm women through improved nursery raising of vegetables. The study was conducted during Kharif 2019 and Kharif 2020 at two locations in two Nutrismart villages. The results revealed that farm women had a huge gap in the knowledge of selection of quality seeds (78%) and preparation of nursery bed and nutrient management (72%). The healthy seedling production under recommended practices and farmer practise was 1860/5 sqm in comparison to 1110/5 sqm respectively. The gross returns, net returns and B: C ratio under recommended practices and farmer’s practice were Rs 9300, Rs 6890 and 3.85 as compared to Rs 5550, Rs 3690 and 2.98 respectively.

The experiments were carried out optimized the chemical concentration as pre-treatments prior to drying of fresh-cut lotus root slices. The lotus root slices were pretreated by chemicals with Potassium metabisulphite (0.1, 0.2, and 0.3 % (w/v)), sodium bicarbonate (2, 4, and 6 % (w/v)), and ascorbic acid (0.5, 1 and 1.5 % (w/v)). The quality parameters of lotus root slices were taken as color parameters such as lightness (L*), redness (a*), and (b*) along with the browning index. The best treatment was decided based on the browning index. The experimental results indicated that the color parameters of fresh-cut lotus root slices and chemicals deteriorate over the time span of 0h to 5h. Besides that, chemically treated samples were improved over the fresh-cut lotus root slices. The lightness (L*), redness (a*), and yellowness (b*) of 0.30% potassium metabisulphite samples varies from 136 to 116, 1.17 to 248, and 2.87 to 5.34 for a period of time 0h to 5h, respectively. Which is the lowest as compared to all other samples. The browning index pre-treated samples was much lower than samples without treatment. The browning index increased with elapsed time and highly increase in untreated (fresh-cut lotus root slices) samples than pre-treated samples (chemicals treated). The optimized browning index was minimum (1.498 to 4.963) for 0.3 % KMS as compared to 5.337 to 16.02 and 2.73 to 9.227 for 6 % (w/v) sodium bicarbonate and 1.5 % (w/v) ascorbic acid solutions, respectively.

Kalanamak rice is a unique cultivar of Oryza sativa L. where Beta Carotene is present. In the freshly harvested grain, the Beta Carotene is 0.42 mg / 100 g, and in one year old sample it is 0.18g / 100 g. Total carotenoids in the these samples were 0.51 and 0.31 respectively. Beta Carotene of Kalanamak needs to be studied further for its conversion rate into Vitamin A. Through various breeding methods, amount of Beta Carotene needs to be increased for remedying Vitamin A Deficiency in the human population. Along with high aroma, high Iron, high Zinc and high protein, semi-dwarf varieties of Kalanamak will be the unique rice of the world. It is non-GMO unlike Golden Rice, and thus non-controversial in consumption and promotion.

Improvement of physicochemical status of soil always should be of major concern before adopting any practices. In the present investigation, we assessed tillage, crop residue and biofertilizer on some physicochemical properties of soil.Results revealed that pH and bulk density both observed to get higher in their level proportionally with depths. Residue and biofertilizers application significantly (p less than 0.05) improved organic carbon contentirrespective of the tillage practice.Higher available nitrogen content observed with the application of residue and biofertilizer in both zero-tillage (ZT) and conventional tillage (CT)at surface layer (0-5 cm). ZT with residue application recorded highest phosphorus (P) at 0-5 cm depth. Residue and biofertilizer both increased the P at 0-10 cm layer; however,biofertilizer involving PSB had better effect in CT than the ZT. Residue application increased the K availability in the plough layer but the effect of biofertilizer found to be restricted to top layer.

The present investigation was carried out to identify fungal infection of five oilseeds viz., rapeseed, mustard, soybean, sesame and perilla oilseeds via different seed health testing methods and seed germination. A total of six seed-borne fungi Aspergillus sp., Colletotrichum sp., Rhizopus sp., Penicillium sp., Nigrospora sp. and Trichoderma sp. were detected from the five oilseeds collected from local market of Medziphema, Nagaland. Amongst the seed health testing methods employed, PDA method was proved to be superior to blotter paper method and water-agar method. The fungal occurrence is more in PDA method with mean incidence of seed mycoflora 15.77%. The predominant fungus was observed to be Trichoderma sp. with 40.67% incidence and the least fungal incidence was of Nigrospora sp. (1.33%). Among the oilseeds, soybean seeds showed highest incidence of seed mycoflora (14.81%) and the lowest incidence of 4.24% was recorded from perilla seeds. The highest germination of oilseeds was recorded in PDA method (50.33%) followed by water-agar method (45.67%).

The dielectric parameters of hygroscopic materials such as seeds and grains vary greatly when subjected to varying electric field. The values of dielectric parameters such as dielectric constant, dielectric loss factor and other related parameters along with dielectric relaxation spectrum has tremendous application in in processing industries, as it helps in determine online and instantaneous moisture content of seed lots during harvesting, processing, handling and transportation and in controlled heating without quality damage. For these operations the effect of frequency moisture and temperature of the material over wide frequency range is required. This paper presents the dielectric properties of sorghum seed (Sorghum bicolour) over the radio frequency range of 0.50 kHz to 10 MHz, determined by Hewlett-Packard (HP-4194A) impedance/gain phase analyzer over the moisture range of 2.9% to 18.5% with corresponding bulk density and temperature range of 0.812-0.760 gm/ cm3 and 30-45oC , respectively.

A field experiment was conducted during kharif season of 2015 at Zonal agricultural research station, Jhabua with the objective to assess the bio-efficacy of atrazine herbicide against complex weed flora and yield of maize crop. The experiment consisted of six treatments, was laid out in randomized block design with three replications. Results revealed that all the weed control treatments significantly reduce the weed density and weed dry matter at 30 and 60 DAS. Atrazine 50% WP @ 1 kg/ha significantly reduced the weed count of grassy as well as broadleaved weeds at 30 and 60 DAA and found at par with Atrazine 50% WP @ 1.5 kg/ha and Atrazine 50% WP @ 2.0 kg/ha. However, better efficacy was observed with higher dose of atrazine viz., Atrazine 1.5 kg and 2.0 kg/ha. Hand weeding was also found as an effective tool for controlling the weed biomass at early stage of observation (30 DAS) but on later stage of crop it proves less effective due to emergence of weeds which further reduce the yield. Further, maize yield (43.43 q/ha) was also found significantly superior in Atrazine 1.0 kg/ha as compared to Atrazine 0.5 kg/ha, hand weeding a 20 DAS and control plot and found at par with higher doses of atrazine. Highest net return of Rs 43203/ha and B:C ration of 3.43 was observed in Atrazine 1.5 kg/ha.

The experiment consisted of six treatments, was laid out in randomized block design with three replications. Results revealed that all the weed control treatments significantly reduce the weed density and weed dry matter at 30 and 60 DAS. Atrazine 50% WP @ 1 kg/ha significantly reduced the weed count of grassy as well as broadleaved weeds at 30 and 60 DAA and found at par with Atrazine 50% WP @ 1.5 kg/ha and Atrazine 50% WP @ 2.0 kg/ha. However, better efficacy was observed with higher dose of atrazine viz., Atrazine 1.5 kg and 2.0 kg/ha.
