 ABSTRACT

An experiment was conducted on weed control in direct seeded rice under rainfed condition at college farm, college of agriculture, Rajendranagar, Hyderabad, during kharif, 2010. The soil of the experimental site was sandy clay loam in texture with a pH of 7.8, low in available nitrogen, high in available phosphorus and medium in available potassium. The results revealed that early post-emergence application of Cyhalofop-buty + (chlorimuron-ethyl+ mestulfuron-methyl) @ 90+20 g ha-1 applied at 20-30 DAS resulted in lower weed density and weed dry matter production, thus gave higher weed control efficiency (82.13%). The same treatment recorded higher grain yield (3820 kg ha-1) and found at par with two hand weedings treatment (at 20 and 40 DAS). The highest B: C ratio of 2.44 was found with Cyhalofop-buty + (chlorimuron-ethyl+mestulfuron-methyl).
