Effect of mechanical intercultivation on growth and yield of soybean
Author(s): AA Patil, BT Shete and US Surve
Abstract: A field experiment entitled “Standardization of mechanical intercultivation in soybean†was undertaken during kharif, 2018 at F block, Seed cell unit, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar (Maharashtra). The experiment consists of eight treatments laid out in randomized block design with three replications. The soil was loamy in texture, high in available nitrogen (330.12 kg ha-1), medium in available phosphorous (16.83 kg ha-1) and high in potassium (308.02 kg ha-1). The growth parameters viz.plant height (59.04 cm), plant spread (35.19 cm), number of leaves plant-1(43.56), number of branches plant-1(6.03), number of active root nodules plant-1(46.81), and were recorded highest onapplication Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS. The yield contributing characters recorded at harvest viz.number of pods plant-1(49.78), pod weight plant-1(22.40 g), number of seeds pod-1(2.75), number of seed plant-1(136.89), 100 seed weight (12.08 g) were obtained highest on application Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS. The highest seed yield (29.95 q ha-1) and stover yield (38.63 q ha-1) of soybean was obtained Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS. The soil moisture percentage at 60 DAS (16.22 %) was recorded highest on Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS. The highest gross returns (Rs. 114761ha-1) and net monetary returns (Rs. 61557ha-1) were recorded on Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS. The similar trend was observed in case of benefit: cost ratio. The highest benefit: cost ratio (2.16) recorded with Pre-emergence application of pendimethalin @ 38.7 % CS PE @ 0.750 kg a.i ha-1 + opening of conservation furrow by tractor ridger at 30 DAS.
