PHOSPHORUS MANAGEMENT ON ECONOMICS AND NUTRIENT BALANCE OF CHICKPEA-FODDER SORGHUM CROPPING SEQUENCE
The Field experiments were conducted at the College Farm, N.M. College of Agriculture, Navsari Agricultural University, Navsari during rabi and summer seasons of 2014-15 and 2015-16. The treatments comprised for chickpea were two levels and two sources of phosphorus (25 and 50 kg P2O5/ha from SSP and rock phosphate) along with and without VAM (Vesicular arbuscular mycorrhizae) @ 2.0 kg/ha as soil inoculants and one control i.e., control (No phosphorus and VAM to chickpea) and making ten treatment combinations, laid out in a randomized block design, replicated three times. The succeeding fodder sorghum crop was superimposed on the same layout, keeping chickpea treatments as main plots and two fertility levels as sub-plots (75 % of the recommended dose of 60 kg N + 30 kg P2O5/ha and 100% of the recommended dose of 80 kg N + 40 kg P2O5/ha) with total twenty treatment combinations in a split plot design with three replications. The experiments were conducted on the same site during both the years without changing the randomization of treatments. The higher chickpea equivalent yield, net realization obtained from the treatment combination of 50 kg P2O5/ha from SSP + with VAM (T8) to preceding chickpea and application of 100 per cent RDF to succeeding fodder sorghum under chickpea-fodder sorghum cropping system. The balance sheet of soil available N, P and S after two years of cropping cycles were positive with all treatments except N balance observed under chickpea [grown with no P and VAM and 25 kg P2O5/ha from RP alone]-fodder sorghum cropping system. The positive balance of these nutrients increased with increasing levels of phosphorus management to chickpea. The soil available K balance showed a negative balance in all treatments under chickpea-fodder sorghum cropping system.
Optimization of the pre-treatment combinations for the minimal processing of garlic cloves by using I -Optimal Response Surface Methodology
Garlic cloves were blanched (normal, hot water, and steam) and subsequently pretreated with various chemicals. Chemicals studied in this pretreatment experiment were acetic acid in the range of 0-2%, potassium metabisulphite (KMS) in the range of 0-2000ppm, EDTA in the range of 0-1%, and Calcium chloride in the range of 0-2%. The pretreated cloves were stored under ambient conditions (Temp 25-35°C and RH 60-80%) for 15 days before taking observations. The change in allicin activity, change in textural property, and change in colour intensity of the treated clove in reference to fresh cloves were recorded as response in this optimization study. The optimization was conducted following I- Optimal Response Surface Methodology with total 43 runs divided into 5 blocks. The mean ranges for change in allicin content after 15 days of storage were 7.5-93.5% having R2 =0.98, the change in textural properties were from 13.63-86.07 % having R2 =0.97 and colour intensity 7.25-20.04% having R2 =0.99 for the responses. Numerical optimization of the model parameter was resulted into the best combination of the hot water blanching cloves and subsequently dipping in the solution of 2% Acetic acid, 0.307 ppm potassium metabisulphite (KMS), 0.037% EDTA, and 1.9% Calcium chloride for 39.367 minutes having the desirability of 0.839 and second best optimized pretreatment solution for peeled garlic cloves were dipped in the solution of acetic acid 2%, 0.050ppm KMS, 1.2% of calcium chloride for 1.165% having the desirability of 0.789.
Interactive response of organic mulch and different nutrient sources on productivity and profitability of rice - potato cropping system
Several ill effects in soil and human health as well as environmental hazards were noted due to the use of imbalance nutrient application. Nutrient management is necessary to balance the soil nutrient input with the crop requirement. Therefore, the field experiment was conducted during the kharif and rabi seasons of 2020-21 and 2021-22 at Research Farm of ICAR-CPRI-RS, Gwalior, to examine the interactive effects of organic mulch and different nutrient sources on productivity and profitability of rice - potato cropping system. The experiment was conducted in randomized block design with three replications. The treatment combination consisted of two factors such as mulch (No mulch and paddy straw mulch @5 t/ha) and different sources of nutrients (100% RDF, Compost @25 t/ha + Azotobacter @1.25 l/ha + PSB @1.25 l/ha + Jeevamrut @500 l/ha, FYM @25 t/ha + Jeevamrut @500 l/ha and control). Results revealed that, application of paddy straw as mulch @5 t/ha significantly resulted in the highest grain (2.73 t/ha) and straw (5.52 t/ha) yield of rice, tuber and haulm yield of potato (23.48 t/ha and 10.38 t/ha, respectively) and net return (2,54,975 ₹/ha). Among various nutrient sources, application of 100% RDF significantly recorded the highest grain yield of rice (3.81 t/ha), tuber and haulm yield of potato (26.43 t/ha and 12.55 t/ha, respectively) as well as improved the system productivity as compared to all other treatments but maximum net return (2,76,630 ₹/ha) obtained under FYM @25 t/ha + Jeevamrut @500 l/ha.
Effect of Plant Growth Regulator and Vermicompost on Growth and Yield Parameters of Bottle Gourd [Lagenaria siceraria (mol.) standl.]
The present investigation in titled “Effect of growth regulators and vermicompost on female flower in bottle gourd [Langeraria sicenaria (mol.) standl.]’’ by Growth Regulators” at the Horticulture Research Farm, R.A.K college of Agriculture, Sehore (M.P.) during 2019-20 and 2020-21. This experiment was laid down in Randomized block design with three replications. The thirteen treatments viz., T1 (GA3 0 ppm + Vermicompost @ 0), T2 (GA3 25 ppm + Vermicompost. @ 2 t/ha), T3 (GA3 50 ppm + Vermicompost @ 4 t/ha), T4 (GA3 75 ppm + Vermicompost @ 6 t/ha) T5 (Etherel 100 ppm + Vermicompost @ 2 t/ha.), T6 (Etherel 200 ppm + Vermicompost @ 4 t/ha.), T7 (Etherel 300 ppm + Vermicompost @ 6 t/ha.) T8 (NAA 100 ppm + Vermicompost@ 2 t/ha.), T9 (NAA 150 ppm + Vermicompost @ 4 t/ha.), T10 (NAA 200 ppm + Vermicompost @ 6 t/ha.), T11 (CCC 200 ppm+ Vermicompost @ 2 t/ha.), T12 (CCC 400 ppm + Vermicompost @ 4 t/ha.) and T13 (CCC 600 ppm + Vermicompost @ 6 t/ha.) were evaluated during the experiment. The maximum days taken to first female flower were recorded under the treatment T1 (61.33 in 2019-20) and (62.00 in 2020-21). While the minimum days taken to first fruit picking significantly recorded under the treatment T6. In relation to sex ratio, the maximum sex ratio of flowers recorded under the treatment T1 (11.67 in 2019-20) and (10.83 in 2020-21. While the minimum sex ratio of flowers v experiment the treatment T6 found superior compare to control treatment.
Influence of weather on thrips population and tospovirus disease incidence in tomato crop
The present investigation on the population dynamics of thrips and bud necrosis disease on tomato crops (cv. Arka Vikas) was carried out during two consecutive crop growing seasons of Kharif, 2016 and 2017. Results revealed that there were two thrips species (Thrips palmi Karny and Scirtothrips dorsalis Hood) that occurred together at different crop growth stages and the population was high during the flowering stage (5.25 to 9.35 thrips/top three leaves), which later started to decline at crop maturity. The symptoms of bud necrosis disease started appearing after 3rd week of transplanting and increased gradually with necrosis symptoms on terminal buds followed by necrotic streaks on petioles and stems, leading to the complete collapse of the plants. The cumulative disease incidence was 43.80 % at the harvesting stage. Correlation analysis with the weather parameters indicated that rainfall and relative humidity exhibited a significant negative correlation with the thrips population and associated bud necrosis disease. While, the correlation of the miridbug, Nesidiocoris tenuis population, was linear with the thrips population and found throughout the cropping period.
