Abstract
A field experiment was conducted at College of
Agriculture, Loni farm during kharif 2015 entitled “Integrated Weed Management
in Soybean” on silty clay loam soil with 7.4 PH. The climatic
conditions were suitable during experimental period. The experiment was laid
out in randomized block design with three replications and eight treatments.
The treatments were consisting of combination of pre and post emergence
herbicides, cultural treatments as well as unweeded check. The results indicated
that the minimum number of weed count, weed dry matter and weed index were observed
in treatment one hoeing at 15 DAS and two HW at 20 and 45 DAS, followed by
treatments pendimethalin 30 percent CS (PE) @ 700 g a.i. ha-1 fb 1
HW 30 DAS, meteribuzin 70 percent WP (PE) @ 525 g a.i. ha-1 fb 1 HW
30 DAS, meteribuzin 70 percent WP (PE) @ 525 g a.i. ha-1 fb
quizalofop ethyl 5 percent EC (POE) @ 50 ga.i. ha-1 at all the
stages of plant. However the highest percent of the weed control efficiency was
recorded with treatment one hoeing at 15 DAS and 2 HW at 20 and 45 DAS which
found significantly superior over rest of the treatments which was followed by
the treatments pendimethalin 30 percent CS (PE) @ 700 g a.i. ha-1 fb
1 HW 30 DAS, meteribuzin 70 percent WP (PE) @ 525 g a.i. ha-1 fb 1
HW 30 DAS and meteribuzin 70 percent WP (PE) @ 525 g a.i. ha-1 fb
quizalofop ethyl 5 percent EC (POE) @ 50 ga.i. ha-1. Significantly maximum
number of weed count, weed dry matter, weed index and lowest weed control
efficiency were noticed in treatment unweeded control.
