Abstract
Field experiments were conducted at the University of Agriculture, Faisalabad to determine the effect of seeding density and planting time on yield and yield attributes of direct-seeded coarse rice cv. IRRI-6 during 1996 and 1997. The seeding density comprised 75, 100 and 125 kg ha", while the planting times were 1st and 3rd week of June and 1st week of July. Planting during the lst or 3rd week of June @ 100 kg ha" produced grain yields of3.91 and 3.29 t ha" in 1996 and 4.28 and 4.10 t ha,l in 1997. Increase in grain yield were due to increased number of panicle bearing tillers m", number of spike lets panicle" and 1000-grain weight. Late planting with a seed rate of 125 kg ha" gave minimum yield of2.32 t ha" in 1996 and 3.02 t ha" in 1997. Key words: agronomic traits, direct-seeded coarse rice, seeding density, planting time
