ABSTRACT
This research was carried out in order to compare the impact of purple nutsedge allelopathy and other approaches on weed management in barely at Students’ Experimental Farm, Department of Agronomy, Sindh Agriculture University, Tandojam for weed as well as barely parameters having eight treatments with three replications. The data revealed that the maximum weed control (91.3%) was recorded under T7= Puma super 7.5% emulsifiable water at 0.625 liters ha-1, 50% reduced (30 Days after sowing) + Purple nutsedge water extract at 15 liters ha-1 (45 Day after sowing). The barley crop’s results revealed that maximum tillers (355.6 m-2), plant height (106.3 cm), spike length (11.5 cm), grains spike-2 (47.3), seed index (51 g), biological yield (11737 kg ha-1), grain yield (4493 kg ha-1) and harvest index (41.9%) were recorded under T7 = Puma super 7.5% emulsifiable water at 0.625 liters ha-1 50% reduced (30 Days after sowing) + Purple nutsedge water extract at 15 liters ha-1 (45 Days after sowing). Hence, it was suggested that application of puma super 7.5% emulsifiable water at 0.625 liters ha-1, 50% reduced (30 Days after sowing) + Purple nutsedge water extract at 15 liters ha-1 (45 Days after sowing) apply for getting higher yield (4493 kg ha-1) of barley crop. It was finalized that this study will be very fruitful for the future progress of barley yield.
