Combined Effect of Soil Water Regime, Nitrogen and Potassium on Yield and Protein Content of Wheat

Nitrogen and soil water increased significantly the yield and protein content of wheat. At lower soil water regime, the higher dose of N increased grain yield. while at higher soil water regime the grain yield was even more than double with lower dose of N, and higher dose of N decreased the yield. Higher percentage of protein in grain was found when the soil water regime was less and a lower percentage under the higher level of soil water. But the total content of protein (g pot⁻¹) was found higher in higher level of soil moisture. The same trend was observed in the case of straw also.
