An investigation on determining the most suitable nitrogen and zinc fertilizer doses for the main crops of Sorghum-Sudangrass Hybrids (Sorghum bicolor X Sorghum sudanense) in the Çukurova Region (Turkey)

This study was carried out in order to determine the most suitable nitrogen and zinc fertilizer doses for the main crops of sorghum-sudangrass hybrids in the Çukurova Region during 2001-2002 at Çukurova Agricultural Research Institution. Grazer cultivar of Sorghum-Sudangrass hybrids and as pure fertilizer doses 0, 7, 14, 18, 24 kg/da nitrogen and 0, 0.5, 1.0 kg/da zinc were used in the study. As a result of this research, while the highest total fresh yield was obtained with 5722.97 kg/da value from N18-Zn0 treatment, the lowest total fresh yield was obtained with 4415.00 kg/da value from N0-Zn0 treatment. While the highest total dry matter yield was obtained with 1602.87 kg/da value from N14-Zn1 treatment, the lowest total dry matter yield was obtained with 1185.88 kg/da value from N0-Zn0.5 treatment. In general, the effect of nitrogen and zinc treatments on the fresh and dry matter yield was found to be significant. While the highest crude protein yield was obtained with 5498.085 kd/da value from N18-Zn0 treatment, the lowest crude protein yield was obtained with 4030.665 kg/da value from N0-Zn0.5 treatment. In general, N and Zn application increased crude protein yield. While the ADF rate was obtained with % 47.560 values from N7-Zn1 treatment, the lowest ADF rate was obtained with % 44.525 values from N0-Zn0.5 treatment. The rate of increasing Zinc ration caused maturation, low protein and high ADF contents.
