Energetics of different cropping systems as affected by resource conservation practices under sub-tropical conditions of Jammu Region

Paper ID- AMA-20-02-2022-11149

A field study was conducted (2012-14) on “energetics of different cropping systems under resource conservation practices” at the research farm, FSR, Centre, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main Campus, Chatha, Jammu, India. The experiment was laid out in split-plot design with two crop establishment methods (Minimum/Zero tillage and conventional tillage) and three cropping systems (Rice-Wheat, Rice-Marigold-French bean and Maize + soybean -Wheat) and two fertilizer rates (Rec. Dose of Fertilizer and 75% RDF + 25% N through FYM) with and without mulching in sub-plots under clay loam soil having alkaline in reaction (pH-8.1), medium in soil organic carbon (0.55%) available P (19.20 Kg ha-1 & K(122.0 Kg ha-1) and low in available N (221.12 Kg ha-1) with three replication The maximum input energy (105241 MJ) was recorded under mulched treatment and the maximum EUE was recorded 7.69 % and 7.01 % under maize + soybean - wheat cropping system followed by rice-wheat cropping system (7.49 % and 6.87 %) during first and second year of experimentation, respectively.

Rice threshing and separation process based on detachment force property of rice ears

Paper ID- AMA-20-02-2022-11148

The movement characteristics of rice are important indicators to explore the optimal threshing area and threshing force. This paper presents the motion parameters for threshing straw in the tangential and axial threshing units of the combine. Through the study of the optimal threshing area and threshing force, the reasons for the non-threshing of grains were obtained, which provided the basis for the design of the longitudinal and axial threshing drum. By comparing the threshing force and the detachment force of the grain stem, stem branch and branch axis, the threshing ability of each part of the longitudinal and axial threshing drum was obtained. The results showed that the separation force ranged from 1.48N to 2.29N. The straw performs approximately periodic helical motion in the axial threshing device. The grains on the ears are threshed by the ears of 1-6 rows of longitudinal and axial threshing drums. 2-3 rows of beaters produce stalked grains, and the optimum threshing force is 2.06 N-2.15 N to ensure threshing without stalks and branches. The research is of great significance to explore the optimal threshing zone and threshing parameters.

Dynamics of soil properties and fruit productivity of Kinnow mandarin (Citrus reticulate Blanco) as affected by drip trickle irrigation and hydrogel

Paper ID- AMA-19-02-2022-11147

An experiment was conducted during 2018 - 2020 to assess the impact of drip trickle irrigation intervals viz. 3 and 6 day water supply and different dose of hydrogel viz. 30, 60, 90 and 120 g of soil application with black polyethylene mulch on soil properties, growth, yield and fruit quality attributes in Kinnow mandarin (Citrus reticulate Blanco). The combination treatment of drip trickle ir rigation intervals and hydrogel with mulch recorded the maximum moisture percentage followed by sole hydrogel and drip trickle irrigation intervals. The three days intervals water supply through drip trickle irrigation and 90 g hydrogel with mulch recorded favourable results with regards to soil moisture and physico -chemical characteristics of the soil. Three days drip trickle irrigation and 90 g hydrogel with mulch were found to be most effective in producing maximum vegetative growth than rest of the trea tments. Plant treated with three days drip trickle irrigation and 90 g hydrogel with mulch recorded maximum yield (9290.76 and 9518.72 kg ha -1), followed by three days drip trickle irrigation and 120 g hydrogel with mulch (8973.84 and 9212.92 kg ha-1) while minimum in control plant (5615.60 and 5924.18 kg ha-1) under two year experimentation. Hydrogel retain water and nutrients, when release to the plants surrounding soil near root zone of starts to dry up and black polyethylene mulch is poor aeration and non-decomposable nature. The improving yield due to fact that soil was wet for a longer time in summer season for improving soil moisture levels and fruit quality in subtropical ecosystem.

Temporal Variations in Area, Production and Productivity of Food Grain Crops in Rajasthan, India

Paper ID- AMA-19-02-2022-11146

Indian economy is an emerging economy, but it is still an agricultural economy because here, most people earn their livelihood from agriculture. The present study for temporal changes in Rajasthan time series, data on area, production and yield per hectare of food grain crops were collected from 1976-77 to 2018-19. Rajasthan state as a whole was selected for the study. The time-series data were collected on area, production, and yield of selected seven Rajasthan crops from the Directorate of Economics and Statistics (DES), Directorate of Agriculture (DOA) and Rajasthan State Agriculture Department. The crops included were wheat, barley, maize, bajra, gram, moong and urad. The area under selected crops in Rajasthan changed remarkably from 1976-77 to 2018-19. The area under barley was reduced, which was shifted towards pulses, oilseeds and cereal crops like moong, urad, soybean, rapeseed & mustard and wheat. The area under wheat, maize, bajra moong and urad had increased during the study period. During the study period, the average total production and yield increased to unprecedented levels in all the selected crops. The area under gram and barley reduced during the study period. Therefore, technological support through varietal improvement and extension support is required.

Influence of Weed Management and Phosphorus Fertilization on Nutrient content, Uptake and Biochemical Parameters of Cowpea [Vigna unguiculata (L.) Walp.]

Paper ID- AMA-18-02-2022-11145

A field experimentation was undertaken during kharif 2019 at Instructional Farm of Agronomy, Rajasthan College of Agriculture, Udaipur to study the influence of weed management and phosphorus fertilization on nutrient content, uptake and biochemical parameters of cowpea (Vigna unguiculata (L.) Walp.). Outcome of this research revealed that maximum chlorophyll content, seed protein content, nitrogen and phosphorus content of seed and haulm and their uptake by seed, haulm and total uptake by cowpea crop were recorded with pre-emergence application of pendimethalin 750 g ha-1 in combination with imazethapyr + imazamox 33.75 g ha-1 as post-emergence at 15-20 DAS next to weed free treatment. Whereas, application of phosphorus at various doses influenced chlorophyll content, seed protein content, nitrogen and phosphorus content of seed and haulm and their uptake by seed, haulm and total uptake by cowpea crop significantly.
