Abstract
In order to study the effect of different levels of nitrogenous fertilizer in combination with phosphate bio-fertilizer on grain yield of maize single cross 704 test, an experiment in split-plot in randomized complete block design with three replications was conducted in Islamic Azad University Khorasgan Isfahan Branch in 2011-2012. Treatments consisted of four levels of nitrogenous fertilizer including 50, 100, 150 and 250 kilogram per hectare as the main plot and three levels of fertilized phosphate fertilizer type 2 including 0, 100 and 200 grams per hectare as sub-plots. Maize cultivar of single cross 704 was used in this experiment. Results obtained from analysis of variance of data showed that different levels of nitrogenous fertilizer in combination with phosphate bio-fertilizer had a significant effect on grain yield. However, this had not significant effect on seed protein percentage, days to tasseling, days to flowering, days to physiologic maturity and yield of number of ears per plant. The results obtained from comparison of means considering different levels of nitrogenous fertilizer showed that the highest grain yield was obtained when using 150 kilogram per hectare and 200 kilogram per hectare nitrogenous fertilizer. Moreover, the results obtained from comparison of means considering different levels of phosphate bio-fertilizer showed that 200 gram per hectare phosphate bio-fertilizer had the highest effect on grain yield (6571.30). Comparison of the interactions between nitrogenous fertilizer and biofertilizer showed that the highest grain yield was obtained when 200 kg per hectare nitrogenous fertilizer in combination with 200 kilogram per hectare bio-fertilizer was used. In contrast, the lowest grain yield (4460.60 gram per meter) was obtained when 100 kilogram per hectare nitrogenous fertilizer in combination with 0 kilogram per hectare bio-fertilizer was used.
