Abstract
University of Zabol in Sistan was conducted at the dam in order to evaluate the effect of tillage systems on yield and yield components of wheat (Triticum Aestivum) under the influence of nitrogen fertilizer, Experiment split plot in a randomized complete block design, with three replications in a crop season 2014-2015 agricultural Research Station. Tillage systems include: No tillage, minimum tillage and conventional tillage as main plot and nitrogen include: 0, 100, 160 and 220 kg ha-1 of urea as were sub plot. The results showed that the highest yield impact of tillage systems were conventional tillage systems, No-till and reduced tillage systems, but yield there was no statistically significant difference. Maximum plant height, leaf area index, tiller number per plant, number of kernels per ear, thousand grain weight, harvest index, and grain protein content in conventional tillage systems, respectively. With increasing levels from zero to 220 kg nitrogen plant height, leaf area, number of fertile tillers per plant, number of kernels per ear, thousand grain weight, seed, harvest index, and grain protein content was significant. Tillage systems and nitrogen interactions on the number of tillers and leaf area index was also significant. The highest number of tillers and leaf area index in conventional tillage with 220 kg N ha-1 respectively. The results showed that conventional tillage systems with high levels of nitrogen fertilizer are the appropriate region.
