Studies on Seeding Depths and Establishment Methods of Direct Seeded Rice in North-Western Indo-Gangetic Plains

The experiment was conducted at Students’ Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana (Punjab) during kharif 2009 to study the effect of crop establishment methods and weed control methods on growth and yield. The rice seeds should not be drilled beyond 2 cm depth in the soil regardless of soil type for optimum crop stand. Weed dry matter accumulation, effective tillers and grain yield did not vary significantly among establishment methods. The maximum grain yield (71.06 q) was recorded in weed free treatment which was at par with integrated use of pendimethalin 0.75 kg/ha with bispyribac 0.025 kg or azimsulfuron 0.02 kg/ha.
