Effect of different Weed Management Practices on Weed Dry Matter Accumulation and Weed Population in Chickpea (Cicer arietinum L.) and Lentil (Lens culinaris L.) Intercropping System

A field experiment was conducted in Lovely Professional University during the winter (Rabi) season of 2019-2020 at Phagwara, Punjab to determine the weed control efficiency of different herbicides on chickpea intercropping with lentil. By using different weed management practices in chickpea and lentil with different doses of herbicides viz. T1: Pendimethalin @ 0.75kg/ha at 2 DAS, T2: Fluazifop-p-butyl @ 0.5 kg/ha at 30 DAS, T3: Metribuzin @ 1.0kg/ha at 2 DAS, T4: Imazethapyr @ 0.75kg/ha at 30 DAS, T5: Isoproturon 1.0kg/ha at 30 DAS, T6: Hand weeding at 30 DAS, T7: Hand weeding at 30, 60 DAS, T8: Weedy free, T9: Weedy check data were evaluated in randomized block design with three replication under irrigated conditions. Due to weed competition, the yield of chickpea and lentil were reduced. These weed management practices help to increase the yield of chickpea intercropping with lentil. This study was taken to know the weed control efficiency of herbicides in chickpea intercropping with lentil. The weed competition was highest during 30 DAS and the maximum weed density was found in 60 and 90 DAS. Weed species were recorded such as broadleaf weeds like Coronopus didymus, Chenopodium album, Melilotus officinalis, Phalaris minor, etc. The main focus of this experiment was to study dry matter accumulation by weeds at different days after sowing (30, 60, 90, and 120).
