The effect of integrated weed management on growth and yield of chickpea (Cicer arietinum L.) in sub humid zone of Rajasthan

Abstract

A field experiment was conducted at Research Farm of Mewar University, Chittorgarh (Rajasthan) during rabi season, 2024-25 on loamy sand soil, which consisted nine treatments viz., weedy check-T1, Weed free-T2, one hand weeding 25 DAS-T3, Oxyfluorfen 100 g a.i./ha Pre emergence-T4, Oxyfluorfen 100 g a.i./ha Pre emergence+one hand weeding 25 DAS T-5, Imazethapyr 50 g a.i./ha Post emergence (25 DAS) T-6, Imazethapyr 50 g a.i./ha 25 DAS + one hand weeding 50 DAS T-7, Oxyfluorfen 100 g a.i./ha Pre emergence + Imazethapyr 50 g a.i./ha 25 DAS T-8 and Oxyfluorfen 100 g a.i./ha Pre emergence + Imazethapyr 50 g a.i./ha 25 DAS + one hand weeding 50 DAS T-9 in randomized block design (RBD). The chickpea var. RSG-888 was used for experiment. Results clearly showed that application of weed free (T2) significantly increased plant height, number of branches plant-1, number of pods plant-1 and seed yield of chickpea as compare to rest of the treatments and statistically being at par with Oxyfluorfen 100 g a.i./ha Pre emergence + Imazethapyr 50 g a.i./ha 25 DAS + one hand Weeding 50 DAS (T9) whereas lowest value recorded under control.
