Investigation on the Carry-over Effects of Various Pre- and Post-emergence Herbicides Applied Alone and in Combination to Cotton on Succeeding Chickpea Crop

Abstract

A field experiment was conducted in kharif and rabi season during 2018-19 and 2019-20 at cotton research scheme farm, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (M.S) under irrigated condition (drip) and studied the effect of various pre- and post- emergence herbicide treatments used alone or in combination for weed control on cotton and subsequent chickpea (Cicer arietinum L.) crop. Without using any weed control techniques, chickpea was grown on the same field after the cotton crop had been harvested. Three replications of the randomized block design were used to evaluate seven different treatments. The crop was significantly affected by all herbicide applications, with the exception of hand weeding at 30, 60, and 90 DAS. From the current study, it can be concluded that crops like chickpeas cannot be grown in a safe order after cotton because using pyrithiobac sodium 62.5 g/ha as PE + quizalopfop ethyl 50 g/ha at 60 DAS as the weed management practice in cotton had a significant impact on growth, yield, and economics.
