Abstract

The field experin~nt was carried out during rainy (kharN season of 1990 and 1991 at Jorhat to find out effective weed-management practice in transplanted rice (Oryza saliva L.). Closer spacing (15 cm x 15 cm) and weeding with rottary weeder reduced the weed growth effectively and increased the grain yield compa- rable to weed-free condition. Among the herbicides, bupchlor (@ 1.0, cinmethyline @ 0.06 and anilofos @ 0.40 kgha proved effective in controlling weeds and recording crop yields similar to that under weed-free condition. The highest additional net return (Rs 2,250) was obtained in rottary weeder (days after trans- planting). Amongst the herbicides, butachlor @ 1.0 kgha gave the maximum additional return (Rs 2,122).
