Effect of different nitrogen fertilizers on growth and yield of wheat

الملخص EN

An experiment was conducted to study the effects of three different nitrogen fertilizers (Ammonium sulfate AS), diammonium phosphate DAP and urea), two wheat species and their interaction on plant height, number of tillers, flag leaf area, shoot dry weight, leaf chlorophylls, number of spikes plant-1, thousand seed weight, grain yield, nitrogen and grain protein content.

N fertilizers significantly increased all tested parameters of growth, DAP followed by AS were a more efficient N source than urea.

Effect of species was significant on all mentioned traits except chlorophyll b, number of spikes plant-1, nitrogen and grain protein content.

The interaction between both studied factors brought about significant increases in all mentioned traits except number of spikes plant-1.
