Evaluation of Pre and Post Emergence Herbicides for Weed Control on Growth and Yield in Chickpea

Abstract

Chickpea, scientifically known as Cicer arietinum L., is a significant grain legume that is cultivated in 44 countries across five continents. India holds the position of the world's largest producer of chickpeas, contributing to approximately 75% of global production. The primary states in India where chickpeas are extensively grown include Maharashtra, Andhra Pradesh, Bihar, Karnataka, Madhya Pradesh, Rajasthan, Uttar Pradesh, and Gujarat. The aim of the experiment was to assess how various herbicides impact weed control in chickpea cultivation. An agronomic investigation on “Evaluation of pre and post emergence herbicides in chickpea (Cicer arietinum L.)” under late sowing conditions was conducted during Rabi 2019-20 at Doon PG College of Agriculture Science and Technology, Selaqui, Dehradun. To study the effect and performance of different weed control treatments. The experiment was laid out in a Randomized Block Design with eight treatments. The treatments were Pendimethalin@1.0 kg ha-1, Metribuzin @1.0 kg ha-1, Quizalofop-p-ethyl @ 40 a.i. g ha-1, Clodinafop @ 0.060 kg ha-1, Pinoxadan @0.005 kg ha-1, Hand weeding at 20 and 40 DAS, Weedy check and Weed Free. They were replicated three times. Observations on growth and weed parameters were recorded periodically at an interval of 30 days. Among the treatments, weed-free recorded the highest grain and straw. It was on par with Pendimethalin @ 1.0 kg ha-1 significantly superior over the rest of the treatments. Among the chemical weed control treatment application of Pendimethalin @1.0 kg ha-1 was found beneficial to higher grain yield, and straw yield and effective in controlling weeds and increasing the yield of chickpea.
