اثر کود زیستی و پرایمینگ بذر بر خصوصیات سبز شدن و عملکرد نخود در مقادیر مختلف کود فسفات

To investigate the effect of on-farm seed priming and two bio-fertilizers on emergence and yield characteristics of chickpea an experiment was conducted in Hamedan factorialiy in randomized complete block design with 3 replications in 2013 crop year. The factors consisted of phosphate fertilizer (0, 50 and 100 percent of recommended) bio-fertilizer (mycorrhizae, Barvar2, both of them and no-application) and priming (priming and no-priming). Results showed that priming increased emergence percent by 7.7 and emergence rate by 20.7 in conjunction with mycorrhizae and 100% phosphate fertilizer compared to no-primed, no-phosphate and no bio-fertilizer. Highest biological and grain yield were respectively 849 and 303 g.m-2 that produced by primed seeds with application of two bio-fertilizers simultaneously at 100 and 50% of phosphate recommendation respectively that were 146 and 250 percent more comparing to their controls in own phosphate fertilizer levels. In this study, the highest harvest index were achieved in priming treatment while simultaneous application of two bio-fertilizers with 50 percent of phosphate recommendation.
