EFFECT OF DIFFERENT NITROGEN AND POTASSIUM LEVELS AND FOLIAR APPLICATION OF BORON ON WHEAT YIELD

From the present study, it could be concluded that the highest concentration of nitrogen in wheat grains was obtained at 90 kg N fed-1 in the presence of potassium and spraying with boron. Increasing nitrogen levels increased the amount of nitrogen uptake by grains of wheat. Also the crude protein (%) in grains increased gradually with increasing nitrogen level in the presence of potassium and spraying with boron. The highest concentration of K in grains of wheat was obtained at the high levels of nitrogen in the presence of potassium and spraying with boron. Also the highest amounts of K uptake by the grains of wheat were recorded by the high levels of nitrogen in the presence of potassium and spraying of boron.
