Objective: Barley Hordeum vulgaire L is an important grain crop, and is grown in large areas all over the world. The experiment aims to study the effect of different levels of fertilizer from agricultural sulfur (0, 1500, 3000, and 4500 kg) S / H, and the number of cuttings (without cut, one cut, and cut twice) on the yield and quality of green forage and grain yield for barley crop Iba 99.
Material and Methods: In this experiment, randomized whole section design was used in the arrangement of splinter panels - splinter with three replicates, sulfur levels for the secondary plates and the number of cuttings in the sub-plot plates.
Results: The addition of agricultural sulfur at the level (4500 kg S / H) resulted in a significant increase in the following characteristics: - plant height, number of tillers / m2, number of spikes / m2 and grain yield. Whereas the sulfur level (3000 kg S / E) resulted in a significant increase in the two green forage yields and the number of grains / spike when added and for the first and second seasons in succession.
Conclusion: Sulfur has significant effect on plant height and a significant effect of interference between sulfur levels and the number of leaves and number of tillers /m2, but it has no effect on the percentage of protein matter in green forage. The increase on sulfur has a significant effect on spike and gave the highest rate (509.4 spike / m2), and increase the protein level in grain to the highest rate 16.95.
