Effect Of Integrated Weed Management Practices On Yield Attriburtes And Yield Of Black Gram (VIGNA MUNGO (L.) Hepper In Kharif Season

Abstract

The demonstrate On Farm Trail was conducted through Krishi Vigyan Kendra, Lahar, during kharif season of 2015 and 2016 were conducted on 4.0 ha at 10 farmer’s field in , Block – Lahar, Distt – Bhind(M.P.) to study the effect of integrated weed management on yield attriburtes and yield of black gram (vigna mungo (l.) hepper) in kharif season. The demonstration were comprised 5 weed control treatment – Farmer;s practices (weedy check), weed free, application of pendimethalin @ 1 lit.ha-1 as pre-emergance , Imazaethapyr + pendimethalin (Ready mix) 900 and 800 ml.ha-1 as pre – emergence applied to black gram in R.B.D.. Weed free plot (two hand weeding at 20 and 40 DAS) resulted in its lowest weed count of broad leaf weeds , grassy weeds and dry matter at maturity stage.It also recoreded significantly the highest no of branches plant -1 , pods plant -1 , seeds pod- 1, grain yield Q ha-1 and stover yield Q ha-1 over other treatments. Among the different weed control treatments , the highest weed control efficiency was recorded with the application of emergance Imazaethapyr + pendimethalin (Ready mix) @ 900 ml ha-1 86.80% and lowest weed index (4.30%) was recorded in Imazaethapyr + pendimethalin (Ready mix) @ 800 ml ha-1.
