Abstract
Field experiment was conducted at Pulses Research Sub-Station, Samba, Sher-e-Kashmir
University of Agricultural Sciences and Technology of Jammu during Rabi 2010-11 to find out
effect of post-emergence (POE) herbicide imazathypr along with cultural weed control and
weedy check on yield, yield attributes of chickpea under rainfed conditions. Twelve treatments
consisting of three doses of the POE herbicide (Imazathypr) at 3 different durations (10, 20 &
30 days after germination-DAG) along with weedy check (control), hand weeding and weed
free treatment were tested in randomized block design. The results revealed that significant
reduction in total weed density and weed biomass were observed in treatments viz. two
hand weedings (25-30 and 50-55 DAG) and imazathypr @ 20 g ha -1 at 30 DAG which in turn were
at par but superior than weedy check treatment and hence resulted in significant improvement
in yield attributing characters viz. no. of pods plant -1 , no. of seeds pod -1 , seed index, dry-
weight plant -1 and seed yield than the other treatment combinations and weedy check
treatment during the period under study. The yield and yield attributes were highly negatively
correlated with weed infestation.
