The project examining the effect of nitrogen azote and phosphorus chemical fertilizer to increase provender function reproduced in Mehrian region in pastures needed land was chosen before according to present factors, the best project, rail factor test in complete blocks plan at random. in the four repeat the effect of azote fertilizer was tested in 4 levels of zero, 20, 40 and 60 kg and the effect of phoshorus was tested in 3 levels of zero, 20 and 40 kg on hectare. In consideration of having 12 fertilizer cares we considered them in each repeat and patch at random. Autumn and nitrogen azore was sprinkled in experimental units during the middle of spring, too. Reaping provender was done before complete flowering of most of plants and at first the weight of wet provender and after 48 hours the weight of bried provender were measured. The test showed that different levels of phosporus nitrogen azote had meaningful effect on provender function. Also most function was on behalf of N40P20 care with dried provender 1636 kg. and the least one was on behalf of NoPo with dried provender 888kg. on hectare.
