Breeding for drought stress conditions in corn is a strategy for national programs in Iran. Phosphorus (P) is
an essential macronutrient for plant growth. This experiment was carried out to investigate the effects of
applications of biological and chemical phosphorus on yield and some morphological traits of corn under
drought stress condition. In order to study the effects of phosphorus fertilizer and phosphorus bio fertilizer on reducing the loss results from stress drought of corn, an experiment was conducted in split plot pattern, using a completely randomized design with three replications. Kernels of KSC704 hybrid were used in this experiment. We used irrigation levels as main plot and three fertilizer treatments in sub-plots. This research revealed that
drought stress levels had significant effects on grain yield of maize. The lowest grain yield (3.04 ton/ha) was
obtained from corn under severe drought stress condition. Compared to the crop under normal irrigation
schedule, this represents a yield decrease of 73 %. The highest Kernel No./Row (48.13) was obtained for the
normal irrigation treatment. The results showed that stress treatment had significant effect on all investigated traits except Row No./ Ear. It was evident that under drought stress condition, seed inoculums with Phosphatesolubilising bacteria and Mycorrhiza fungi with 50 percent of triple super phosphate treatment significantly affected the reduction of plant losses and therefore increased the total yield. |
