Abstract

The experiment was laid out in split plot design with three replications. The main plots comprised three residue management treatments and sub-plots comprised seven weed management treatments. Results revealed that significantly, highest pod yield (1.47 t/ha) with maximum net returns was recorded under the wheat residue incorporation (IC) fb soil solarization. Among the weed management, significantly highest pod yield (1.68 t/ha) and haulm yield (3.35 t/ha) was recorded under weed free and unweeded check registered significantly lowest pod yield (0.72 t/ha). Significantly lower number of total weeds at 30, 60 DAS and at harvest, dry weight of weeds and weed seedbank, lowest weed index and higher weed control index was recorded under the wheat residue incorporation fb soil solarization and weed free. Among the weed management, next superior treatments were pendimethalin fb imazamox + imazethapyr, pendimethalin fb IC and HW and suicidal germination fb tillage fb IC and HW in the both year of 2014 and 2015.
