Effect of Weed Management Practices on Growth and Yield of Zero-Till Chickpea (Cicer arietinum L.)

This is the authors' abstract. We don't add key points for this paper.

A field experiment to compare weed management practices on growth and yield of zero till chickpea (Cicer arietinum L.) during rabi, 2022 at RARS, Jagtial, Telangana. Treatments include Pendimethalin 38.7 % CS @ 700 g a.i. ha-1 , Topramezone 33.6 % SC @ 20.6 g a.i. ha-1 , Quizalofop ethyl 7.5 % + Imazethapyr 15 % EC @ 100 g a.i. ha-1, T4- Propaquizafop 2.5 % + Imazethapyr 3.75 % (w/w) ME @ 125 g a.i. ha-1 , two hand weedings at 15 and 30 DAS , weed free (Season long) and Un-weeded (Check). Weed free treatment and hand weeded plots showed highest growth and yield attributing characters because of season-long weed-free conditions and better microclimate during critical period of crop respectively. Among different herbicides, Topramezone treated plot recorded higher growth parameters viz.; plant height (38.7 cm), dry matter accumulation (320.8 g m-2) and yield attributing characters viz.; total number of pods plant-1 (30.97), with seed yield (1397 kg ha-1), haulm yield (2518 kg ha-1) and harvest index (35.7 %). Post emergence herbicide topramezone can be effectively adopted for getting higher yield of chickpea in rice fallow zero tillage conditions.
