Abstract

A balanced fertilization of NPK nutrients leads to increase soil fertility, anti soil nutrients depletion and also decrease nutrients losses to ground water and hence decrease its pollution. Therefore, a field experiment was conducted for two growing seasons on wheat in North Delta, Egypt. Different levels of nitrogen (0, 96, 192 and 288 kg N ha-1), phosphorus (0 and 53 kg P2O5 ha-1) and potassium (0 and 120 kg K2O ha-1) as well as 4 doses of N fertilizer were used. The objective of the present study was to investigate the effect of previous different levels of N, P and K fertilization and N fertilizer splitting on wheat yield and its components as well as uptake of N, P and K by wheat grain under different treatments. The results revealed that yield and its components were significantly affected by graded applied and splitting of N levels. The protein content in wheat grains was increased with increasing N levels up to 288 kg N ha-1 in presence of 53 kg P2O5 ha-1 as well as 120 kg K2O ha-1. The previous treatment recorded the highest values for protein content in wheat grains and total chlorophyll content.
