Soybean yield and economics as influenced by weed management practices and its carryover effect on follow up crops

An experiment was conducted at AICRP on Weed Management Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during two consecutive Kharif season of the year 2017-18 and 2018-19 on loamy sand soil. Results indicated that maximum seed yield (2.73 t/ha) and gross realization of Rs. 90145/ha was achieved under IC fb HW at 20 and 40 DAS while net realization of Rs. 51212/ha and BC ratio of 2.51 was recorded under application of propaquizafop + imazethapyr 125 g/ha PoE (PM) closely followed by imazethapyr 100 g/ha PoE fb IC +HW at 30 DAS and fluazifop-p-butyl + fomesafen 250 g/ha PoE (PM). The plant stand, plant height and dry matter production of wheat, chickpea and mustard were not affected by the application of different herbicides in preceding soybean.
