Abstract: A field experiment was conducted during the rainy season (kharif) 2000 to 2002 at Agriculture College farm, Nagpur, to find out suitable integrated method of weed control for rainfed cotton. Pre- and post-emergence appli- cation of herbicides along with 2 hand-weedings and 2 hoeings at 20 and 40 days after sowing (DAS) gave ef- fective control of weeds. The highest weed-control efficiency was recorded by pre-emergence application of pendimethalin followed by post-emergence application of glyphosate with 2 hand-weedings and 2 hoeings at 20 and 40 days. Maximum seed-cotton yield (8.54 qlha) was recorded with 3 hand-weedings and 3 hoeings fol- lowed by pre- and post-emergence application of pendimethalin and glyphosate with 2 hand-weedings and 2 hoeings (8.44 @ha). Maximum benefit : cost ratio (1.34) was recorded with 3 hand-weedings and 3 hoeings treatment. Among integrated weed-management treatments, the post-emergence application of glyphosate with 2 hand-weedings and 2 hoeings recorded more benefit : cost ratio compared to other integrated weed-manage- ment treatments.
