Abstract:
A field experiment entitled “Weed Control in Summer Greengram (Vigna radiata L.)” was conducted at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar during Summer season of 2020. The treatments comprised of ten methods of weed control viz., pendimethalin @ 1 kg a.i./ha PE (T₁), imazethapyr 50 g a.i./ha at PoE at 25 DAS (T₂), ready mixture of pendimethalin + imazethapyr 800 g a.i./ha PE (T₃), ready mixture of imazethapyr + imazamox 70 g a.i./ha PoE at 25 DAS (T₄), tank mixture of imazethapyr 30 g a.i./ha + quizalofop-p-ethyl 15 g a.i./ha as PoE at 25 DAS (T₅), ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS (T₆), tank mixture fomesafen 220 g a.i/ha + fluazifop p butyl at 220 g a.i./ha as PoE at 25 DAS (T₇), hand weeding at 25 DAS and 40 DAS (T₈), weedy check (T₉), Weed free (T₁₀) were evaluated in randomized block design with replicating thrice. The plant height, number of branches/plant, number of pods/plant and number of seeds/pod were significantly higher in weed free treatment and was at par with ready mix application of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS. The highest seed yield and stover yield was recorded under weed free treatments, and was remained statistically at par with ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS. In terms of economics, besides weed free situation, most advantageous treatment is ready mixture of clodinafop propargyl + acifluorfen sodium 250 g a.i./ha as PoE at 25 DAS accounted higher net realization followed by hand weeding at 25 DAS and 40 DAS and tank mixture of imazethapyr 30 g a.i./ha + quizalofop-p-ethyl 15 g a.i./ha as PoE at 25 DAS.
