The result with the experimental results Hatami et al (2009) and Ebadi et al (2006) is consistent.
Nitrogen consumption increased by increasing the number of pods per plant and leaf area can increase the
yield The number of pods per plant and plant products are potentially affected and are most effective in
increasing grain yield.Comparison of results with the highest average yield in irrigated for 12 days and 90 kg ha
of nitrogen fertilizer level was assigned (Figure 3) Astare and Scarisbrick (1995) reported that application of nitrogen fertilizer on dry matter accumulation at flowering stage of soybean lines grown in limited and
unlimited growth to 25 percent and grain yield at least 8 percent of all genotypes increased significantly. A
greenhouse study on the early growth of soybean was shown on the application of nitrogen. Nitrogen
consumption is associated with the accumulation of more dry matter in the lead the soybean yield was
increased (Hatami et al, 2009). In the treatment without fertilizer and dry weight of growth It is placed Hndh the
lack of access to additional sources of nitrogen in the critical stages of development leading to production of
less photosynthetic material and Finally, the biological weight loss leaves little to the intensity of the nitrogen is
at this level The result Azizi (1994) is consistent. The highest dry matter was accumulation of 120 kg.N/ha
fertilizer, respectively. Soybeans needed to accelerate the transfer of nitrogen from leaves to seeds is this
element, the remobilization of nitrogen from the green body can cause accelerated aging of leaves (Brevendan
et al, 1978).
