摘要：

A field experiment was conducted during winter seasons of 1990-93 to study the effect of 3 seeding zone moisture conditions created by applying 0, 2.5 and 5.0 cm of water and 3 seed rates (60, 80 and 100 kg/ha). Application of 2.5 and 5.0 cm presowing irrigation increased wheat (Triticum aestivum L. emend. Fiori & Paol.) yield significantly over the control in all the 3 years, the respective increase in yields being 4.4 to 5.5 q/ha with 2.5 cm and 6.2 to 8.9 q/ha with 5.0 irrigation. Higher seed rate too increased the wheat yield under all the 3 seeding zone moisture conditions. Seed rate of 80 kg/ha was at par during 1990-91 and 1991-92 with 100 kg/ha whereas in 1992-93, seed rate of 100 kg/ha gave more yield than 80 kg/ha.
