Optimization of the pre-treatment combinations for the minimal processing of garlic cloves by using I -Optimal Response Surface Methodology

Paper ID- AMA-04-10-2023-12627

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

Paper ID- AMA-03-10-2023-12626

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.]

Paper ID- AMA-03-10-2023-12625

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

Paper ID- AMA-01-10-2023-12623

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.

Paper ID- AMA-29-09-2023-12621

The present study was conducted in Raisen district of Madhya Pradesh during 2020-21 at the school of Agriculture sciences BRAUSS Mhow, M.P. The main objective of the present research was to study the decision making pattern of farm women related to horticultural crops production. For this study 180 randomly selected farm women were taken as a sample from study area. The study revealed that majority of the farmwomen belonged to medium decision making pattern related to horticultural crops production followed by low and high decision making pattern of horticultural crops production respectively.
