| Abstract | ||
| Two field experiments were designed in the Farm of Sids Agricultural Reasearch Station, ARC, Beni Swif Governorate, Egypt to study the effect of different doses of N, P, and K through soil and foliar applications and their interactions on wheat plant (Triticum aestivum L.). Three levels of soil NPK applications, i.e., 0.0, 50%, and 100% from its recommended rates (RR) and four foliar spraying treatments were used (without spraying and spraying two, threee and four times). The results revealed that, plant height, dry weight/plant, number of spikes/m2, number of grains/spike, grain and straw yields, N, P and K concentration and uptake by grains and/or straw as well as protein percentages in grains were significantly increased by increasing the soil application of N, P and K up to the recommended rates or by spraying the plants four times. Combined 50% RR NPK + foliar spraying four times gave highest values of the abovementioned parameters, equal to those obtained by 100% RR NPK. The highest values of N, P and K uptake by grains and/or straw and protein percentage in grains produced under 100% RR + foliar spraying four times. The weight of thouthand grain significantly increased by increasing soil application rates, while, it did not affect by the number of foliar spraying numbers. | ||
