Abstract
In order to effect different levels of nitrogen fertilizer on yield and its components in sunflower (Cultivar Masters) in 2009 in pilot randomized complete block design with three replications was done in University azad Bojnourd branch. Treatments included different levels of nitrogen fertilizer (0, 90 and 180 kg N ha) had Masters and cultivars used. Traits measured, including number of grains per head, Seed yield, grain1000 weight, percentage of osteoporosis, plant height, diameter and stem diameter was. Based on the results, no significant effect on nitrogen increased seed number per head and stem diameter showed. In general, nitrogen consumption increased number of grains per head, Seed yield, Grain1000 weight, plant height, diameter and stem diameter was used, but grain nitrogen percentage of osteoporosis reduced. It seems that the application of 180 kg nitrogen per hectare to achieve good Performance in the test area is advisable.
