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).
