Abstract:

A field experiment was conducted during 2002-03 and 2003-04 to study the effect of integrated weed management in sugarcane ratoon. Echinochloa spp., Cyperus rotundus and Digitaria sanguinalis were the dominating weeds associated with the crop and constituted 17.17, 61.34 and 9.50% of total weed population, respectively. Three hoeings at 30, 60 and 90 days after harvesting (DAH) produced maximum cane yield with the minimum weed dry matter among all treatments, which were at par to pre-emergence application of atrazine at 2.0 or 1.5 kg/ha, supplemented with hoeings at 60 and 90 DAH. Pre-emergence application of atrazine 2.0 kg/ha did not prove efficient to control the weeds.
