Effect of Planting Technique and Weed Management Practices on Ridge-furrowPlanting of Pigeonpea Rice Intercropping

摘要

An experiment was conducted at All India Coordinated Research Project for Dryland Agriculture (AICRP-Dryland Agriculture), Institute of Agricultural Sciences, Banaras Hindu University, Varanasi for three consecutive years from 2014-15,2015-16 to 2016-17 to find out the impact of planting method and weed management practices on ridge-furrow planted Pigeonpea + Rice intercropping. Among the different planting methods tested, planting of pigeon pea and rice at the onset of monsoon resulted in maximum yield of both pigeonpea (1839.64 kg/ha), rice (644.84 kg/ha), PEY (2044.48 kg/ha), LER (1.42) and MAI (13309.37). It also performed better in terms of net returns (67158.68/ha), В: С ratio (3.01) and RWUE both in terms of yield (2.25 kg/ha-mm)and economic returns (73.72/ha-mm). Out of the various weed management practices, 100% population of both crops + hand weeding resulted in higher yield of pigeonpea (1463.33 kg/ha) with PEY (1656.43 kg/ha), RWUE (1.87 kg/ha-mm and 54.35/ha-mm). However, maximum value of rice yield (613.30 kg/ha), LER (1.11) and MAI (7685.07) were reported in treatment involving 150% population of pigeonpea + 100% population of rice and no weeding while 150% population of pigeonpea + 100% population of rice and hand weeding resulted in highest net returns of 49389.77/ha and B:C ratio of 2.31.
