Effect of Herbicidal Weed Management Practices on Weed Dynamics and Productivity of Chickpea (Cicer arietinum L.)

Abstract

Background: This study was conducted in 2017-2018 and 2018-2019 to determine the effects of pre and post herbicides and different doses of applications on the weed dynamics, yield components and yield of chickpea under irrigated condition of Central Punjab region. The main objective of this experiment was to find out the suitable herbicide options to control the weeds along with high profitability. Methods: The experiment was carried out at Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab, during the rabi season of two consecutive years. The experiment was conducted in randomized block design comprised of ten treatments with three replications. Result: The experiment result revealed significantly lowest weed density was found with application of pendimethalin @ 1 kg ha-1 as pre-emergence + quizalofop @ 60 g ha-1 as post emergence and it remained at par with pendimethalin @ 1 kg ha-1 + imazethapyr @ 40 g ha-1 and oxyfluorfen @ 125 g ha-1 + quizalofop @ 60 g ha-1. The highest yield attributes viz. number of pods plant-1, seed pod-1 and seed index and grain yield were recorded under these treatments. The effective control of first flush of weeds by pendimethalin and subsequent flushes by post-emergence application of quizalofop and imazethapyr.
