The second part of this paper presents effects of supplemental irrigation and nitrogen fertilization on nitrate levels in flag leaf, activity of some enzymes and yield Chillums of winter wheat and triticale.Both sprinkling irrigation and high doses of nitrogen enhanced the activity of nitrate reductase and peroxydase and slightly that of acid phosphatase.Plants from plots treated with high rates of nitrogen contained more nitrate nitrogen.Sprinkling irrigation and intensive nitrogen fertilization significantly increased the crops of winter wheat and triticale.

As effect of sprinkling the yield of winter wheat increased by 35 % and triticale by 14 %.High nitrogen doses affected the yield respectively by 92 and 115 % and the combined theplayfulcollectivees.shop effect of both treatments increased the yield of winter wheat by 158 % (3.3 t/ha and triticale by 139 % 3.10 t/ha).
