An experiment conducted during 2001-2002 and 2002-2003 showed 43.4% and 43.9% reduction in cane yield due to weeds. Highest cane yield (84.6 tonneslha and 80.6 tonneslha) was recorded under weed-free con- ditions, which was at par with 3 hoeings (30, 60 and 90 days after planting) during both the years. Significant im- provement in cane yield was reported under treatments comprising herbicide spray followed by hoeing over that of herbicide spray alone. Highest net return of Rs 31,2961ha and 27,989ha was recorded in weed-free treatment during 2001-2002 and 2002-2003 respectively. However, highest benefit : cost ratio of 1:0.58 during 2001-2002 and of 1 :0.55 during 2002-2003 was observed in 3 hoeings (30, 60 and 90 days after planting).References
