Abstract :
Present study was conducted in order to study the effect of manure, biofertilizer and foliar application of iron- and zinc- sulphate on yield and yield components of wheat, )Karim variety( were studied in Iran (Khorram Abad town) during the 2015-2016 growing season. Four levels of manure (20, 25, 30 and 35 ton/ha) were allocated to the main plots and four levels of biofertilizer (Barvar 2) application (100 g/ha as seed inoculation, foliar application of 0.5 percent zinc and 1 percent iron, co-application of biofertilizer and foliar application and without biofertilizer and foliar application as control) were applied to the subplots. During the experiment spike numbers, seed number per spike, peduncle length, spike length, spike weight, 1000-grain weight and grin yield per ha measured. The results showed that application of manure biofertilizer and co-application of iron- and zinc-sulphate caused increasing spike number per plant. The highest spike number obtained with 35 ton/ha manure, application of biofertilizer and foliar application of iron and zinc sulphate (7.44) and the lowest spike number (5.71) observed with 25 ton/ha, biofertilizer and foliar application of iron and zinc sulphate. Application of 35 ton/ha manure, biofertilizer and foliar application of iron and zinc treatment resulted to the highest grain yield (5610 kg/ha). While in this study, the positive impacts of manure and biofertilizers and micronutrients in supplying plant nutrients and reducing dependency to chemical fertilizers for environment protection and wheat importance as most important healthy food sources and according to the results of present study, manures an biofertilizers and foliar application of iron and zinc sulphate could be safe alternative to chemical fertilizers.
