摘要：
Field experiment was conducted to evaluate the effect of different sowing dates on yield and yield components of the direct sown coarse rice during the Kharif season of 2008, at Agronomic Research Area, University of Agriculture, Faisalabad. Experiment comprised of six sowing dates i.e. 31(st) May, 10(th) June, 20(th) June, 30(th) June, 10(th) July and 20(th) July. Data on agronomic parameters and economics of coarse rice were recorded. Results revealed that direct seeded rice sown on 20(th) June proved to be the best for obtaining maximum grain yield and net return. 20(th) June sowing also gave maximum number of productive (panicle bearing) tillers, number of kernels per panicle, 1000-grain weight and benefit-cost ratio.
