Combined effect of herbicides and cultural methods of weed control on growth and yield of summer green gram (Vigna radiata L. Wilczek) under south Gujarat condition

Abstract

A field experiment entitled “Combined effect of herbicides and cultural methods of weed control on growth and yield of summer green gram (Vigna radiata L. Wilczek) under south Gujarat condition.” was carried out with twelve weed control treatments under Randomized Block Design with three replications at Navsari on clayey soil during summer season 2013. The results of present investigation revealed that different herbicides either applied as pre or post-emergence in the experiment was not found phytotoxic to the green gram crop as reflected in initial and final plant stand of the crop and higher grain and stover yield of green gram and net return can be accrued by keeping crop weed free throughout crop season. The next alternatives either adopting two hand weeding and interculturing at 20 and 40 DAS or application of pendimethalin @ 1.00 kg/ha as pre emergence + IC at 40 DAS can be adopted where farm labours are scarce, costly and timely not available.
