Özet

This research was conducted to determine the effects of different sowing rates (450, 550 and 650 seed m(-2)) and sowing methods (sowing to the rows, broadcasting to seeding depth and contrary rows with 90 degrees) on weeds, grain yield and some yield components of wheat local "Tir" variety (Triticum aestivum L. ssp vulgare Vill. v. leucospermum Korn) under dryland condition of Van in 2006-07 and 2008-09 winter growing seasons. It was found that contrary rows with 90 degrees unaffected to reduce weeds density but it was highly effective sowing methods to decrease weeds biomass. However, higher seeding rates, in the current study, reduced insignificantly weeds density, but it reduced weed biomass. In the current study, sowing methods and seeding rates significantly affected grain yields and yields components. The highest grain yield was obtained 650 seed m(-2) and sowing to contrary rows with 90 degrees.
