Abstract

Barley Hordeum vulgaire L is an important grain crop, it ranks fourth after (wheat, rice and yellow corn) and is grown in large areas in most parts of the world and the Arab world. The aim of this research is to study the effect of different levels of nitrogen fertilizer on the yield and quality of green forage and grain yield for barley crop Iba 99 different levels of nitrogen fertilizer (0, 90, 180 and 270) kg N/H and the number of times of cutting (without cut and one and two cuttings) on the yield and quality of green forage and grain yield for barley crop Iba 99.  The design of randomized complete segments was arranged in order of splitting-splitting plates with three replicates. Nitrogen levels were allocated to the main panels, nitrogen levels to the secondary panels and the number of pads in the sub-replicates plots. The study concluded that the addition of nitrogen fertilizer at the level (270 kg N/H) led to a significantly increases in the plant height, number of leaves / stem, number of tillers / m2, area of flog leaf, number of spikes / m2, number of grains/ spike, green forage yield, dry matter yield, grain yield, hay yield and percentage of crude protein in green forage.
