ABSTRACT

A field experiment was conducted during rabi, 2008 to study the effect of different weed management practices on the weed flora and to identify an effective and suitable weed management practice for sweet corn. Growth parameters of sweet corn viz., plant height, leaf area index and dry matter production and green cob and green fodder yields were highest with hand weeding twice at 20 and  40 DAS (T9), which  was on par with, sulfosulfuron + imazethapyr as pre-emergence with hand weeding at 40 DAS (T6) and  were found to be lowest with control (T10). Net returns and benefit cost ratio were highest with sulfosulfuron @ 15 g a.i. ha-1 + imazethapyr @ 25 g a.i. ha-1 as pre-emergence with hand weeding at 40 DAS (T6), which were however, on par with hand weeding twice at 20 and 40 DAS (T9).
