Abstract:

 

The field experiments were conducted during Kharif 2016 and 2017 at Research Farm, College of Agriculture, RVSKVV, Gwalior (M.P.) to study the effective herbicide/combination of herbicides to control the problematic weeds in greengram (Vigna radiata). The experiments were laid out with ten treatments, viz. quizalofop-p-ethyl 50, 75 and 100 g/ha PoE, fenoxaprop-p-ethyl 100 g/ha PoE, pendimethalin 1000 g/ha pre-emergence (PE), pendimethalin + imazethapyr (RM) 750 and 1000 g/ha PE, imazethapyr + imazamox (RM) 80 g/ha PoE, two hand weeding at 20 and 40 DAS and weedy check in a randomized block design. The combination of imazethapyr + imazamox (RM) 80 g/ha applied as post-emergence was found to be very efficient in controlling the dominant grassy as well as broad-leaved weeds and produced maximum seed yield (993 kg/ha), and was at par with two hand weedings at 20 and 40 DAS (983 kg/ha) and combination of pendimethalin + imazethapyr 750 g/ha and 1000 g/ha PE (844 and 758 kg/ha, respectively). Application of imazethapyr + imazamox (RM) 80     g/ha PoE resulted in the highest B:C ratio (3.03), and net returns, fb pendimethalin + imazethapyr 750 g/ha PE and two hand weeding at 20 and 40 DAS.
