Abstract
ABSTRAK Influence of seed rates at 100, 125, 150, and 175 kg/ha and four weeding frequencies W o (no weeding), Wi (weeding after 20 days of sowing), W 2 (weeding after 20 and 40 days of sowing) and~ (weeding after 20, 40 and 60 days of sowing) on growth and yield of wheat were studied. The major weeds species were Chenopodium album L., Cynodon dactylon (L) Pers, Dactyloctenium aegyptium L. and Vicia sativa L. The highest grain yield per hectare, panicle length, andfilled grains/panicle were obtained with the seeding rate of125 kg/ha. The lowest grain yield (3.11 t/ha) with minimum effective tillers/plant, panicle length and filled grains/panicle were produced 1Yy the highest seed rate (175 kg/ha). The plant population per meter square was significantly influenced 1Yy seed rates. Weeding at 20 and 40 days after sowing (W) gave the highest grain and straw yields along with highest effective tillers/plant, panicle length, and filled grains/panicle. On the other hand no weeding treatment gave the lowest grain and straw yields, effective tillers/plant, panicle length and filled grains/panicle. The critical period of weed competition was between 20 and 40 days after sowing. High seed rate with three times weeding (W) decreased weed dry weight/m 2 significantly.
