Evaluate the effect of bio-fertilizers and micronutrients on yield and yield components of maize)Zea mays L.(
In order to investigate the effect of application of biofertilizers and micronutrients on yield and yield components of corn (Zea mays L.) cultivar AS71, a research was conducted in Sarpol-e-Zahab city in 2017, in a factorial arrangement and complete block design Randomization was performed in three replications. Experimental treatments including bio-fertilizers at two levels of Phosphatebarvar-2 and Azotobarvar-1 and foliar application of micronutrients in four levels of control, zinc, manganese, and zinc and manganese foliar application. The results showed that the effect biofertilizers and micronutrients had a significant effect on plant height, stem diameter, number of grains per row, biological yield at 1% level, and hundred grains weight and harvest index at 5% level. The effect of micronutrients on ear length, number of grain rows per ear and grain yield was significantly affected. Comparison of mean of traits showed that the highest grain yield was obtained in foliar application of zinc with 15936 kg ha-1 . Biological yield with 32246.9 kg ha -1 in combination treatment of Azotobarvar-1 with Zn and Harvest index with 61.53 percent in combination treatment of Phosphatebarvar-2 and Zinc element were highest.
