Abstract :This research was conducted to determine the effects of different phosphorus (0-3-6-9-12 kg 1205/da) and zine (0-0.5-1.0-2.0-4.0 kg Zn/da) doses on the grain yield, physical (plant height, car diameter, car length, thousand seeds weight, number of stem) and chemical (P. K. Zn and crude protein content of leaf and grain) characteristics of TTM-813 htybrid maize varieties under irrigation conductions in Konya and was arranged with respect to the randomized block experimental design in the factorial design with four replication. From the result of research the highest grain yield was 334.69 kg/da (the application of 9 kg P205/da and 4 kg Zn/da) and 236.18 kg/da on the control plot. Average phosphorus content of leaf was % 0.20 and that of grain was % 0.31. Average zine content of leaf was 36.4 ppm. While phosphorus uptake of grain was 670.7 g/da on the control plot, the highest was 1136.6 g/da on the plot of 9 kg P 205/da and 4 kg Zn/da applied together. Phosphorus uptake of grain increased with the increasing rate of zine application and it was statistically significant at the l\\\' < 0.05 level.
