assessment of different weed management practices in yield and yield attributes in summer maize in inner terai of nepal

The experiment was conducted in farmer field with farmer managed in randomized complete block design (rcbd) with three treatments and seven replications. the treatments were weed management practices including (i) farmer’s practice (fp) (ii) two manual weeding (iii) first manual weeding and 2nd weeding by post emergence herbicides (temboterine and atrazine) application in inner-terai, dang, nepal. results showed that first manual weeding and 2nd weeding by herbicides significantly reduced weed infestation and gave higher maize grain yield. the yield attributes were cob length, total number of grain, number of grain per row, cob weight with husk and cob weight without husk. thus, herbicides used after 1st manual weeding is successful for high maize yield.
