تأثیر اختلاط پهن برگ کشهای انتخابی و کود کامل بر رشد بوته ها و عملکرد گندم مروارید

In order to investigate the effect of mixing Bromicide M.A. and Dialensuper herbicides with complete nutrient fertilizer on growth and yield of wheat in Golestan province, a factorial experiment arranged in a randomized complete block design with three replications was conducted in fall of 2013 at the research station of Islamic Azad University of Gorgan. The first factor was the levels of 0, 0.75, 1.5 and 3 kg.ha-1 complete fertilizer and the second was recommended doses of commercial Bromicide M.A. and Dialensuper herbicides. Wheat dry weight at 15 days intervals after mixing and yield and its components after plant ripening were measured. Results showed no significant differences in final wheat dry weight due to mixing of herbicides with fertilizer. However, increasing fertilizer level, increased requirement time to achieve 50% final weight from 28 (control) to 38-42 days. Bromaicide or Dialensuper + fertilizer tank mix increased fertile tillers 17 and 26 %, respectively. This has led to increases of yield from 11 to 15 percent. Number of spike, number of grains per spike, grain weight, yield and harvest index indices increased in Dialensuper tank mix more than Bromicide herbicide.
