Abstract

Pre-emergence application of pretilachlor plus 0.3 kg a.i./ha at 3 days after seeding (DAS) with one hand weeding (HW) effectively reduced the density of dominant Trianthema portulacastrum (2.9 No.m-2) which recorded the minimum total weed dry weight (3955 g m-2) and maximum weed control efficiency (WCE) of 85.0 per cent. Pretilachlor plus did not exhibit any crop injury and recorded the maximum seedling growth characters and stand establishment leading to increased number of panicles (319 m). This treatment gave the best per hectare yield of 5.5 t and benefit cost ratio (B:C) of 3.12.
