Effect of nitrogen fertilizer, inoculation with mycort fungus and foliar spraying of cytokinin on yield and yields component of wheat sardari cultivar under rainfed conditions

To investigate the effect of different levels of Mycort fungus, nitrogen fertilizer and cytokinin hormone on yield and yield components of wheat, an experiment was conducted in 2018-19 crop year. The experimental design was a factorial based on randomized complete block with three replications. The first factor was organic fertilizer of mycorrhizal fungus (2, 4 and 6 kg/100 kg seeds), the second factor was nitrogen fertilizer (zero, 25 and 50 kg/ha) and the third factor was cytokinin foliar application (control, foliar application at flowering and grain filling). The results of mean comparisons showed that levels of 25 and 50 kg/ha of nitrogen fertilizer increased the number of grains compared to the control treatment by 44.23 and 32.69%, respectively.resultsshowed that inoculation with 2 and 4 kg/100 kg of seeds along with the application of 25 kg / ha of nitrogen had the highest spike length and number of fertile spikes. The highest number of fertile spikes, number of grains per spike, 1000-kernal weight, grain yield and harvest index were assigned to seed inoculation treatment with 4 kg of mycorta and cytokinin foliar application at grainclosure stage. Also, foliar application of cytokinin in the graining stage along with the application of 25 kg / ha of nitrogenfertilizer had the highest number of spikes, 1000-kernal weight, biological yield and grain yield.
