بررسی تأثیر روشهای مختلف کاشت درشرایط آبیاری متفاوت، بر عملکرد و صفات عملکردی گندم رقم زرین

For investigating the impacts of different planting methods on the yield and other Characters an experiment as split plots in a randomized complete blocks design with three replications on wheat (cultivar of Zarrin) performed on research farm of mahabad in 2009-2010. The main factor is planting method in two levels of linear and sprinkling, and the subsidiary factor comprises irrigation treatments and dry farming. Variance analysis results revealed that the effects of the both factors on all of the traits were significant while the interaction of the two factors was significant only on the characteristics of panicle number per square meter and seed number in each panicle. By examining the comparison of grain yield means and other agricultural traits, the highest significant numeric value belongs to linear planting, except for the panicle number per square meter that had completely reverse trends in both treatments. Ultimately it is concluded that besides economic considerations through decreasing the amount of seeds needed and the easier control of weeds, linear planting helps to increase grain yield by accurately adjusting the distance and depth with regard to the proper positioning of seeds through increasing the claw number and other relevant characteristics of performance.
