Abstract
Two field experiments were carried out on faba bean (Vicia faba L.) Giza 184 at Sakha Agricultural Research Station Farm, Kafr El-Sheikh Governorate, during the two successive winter seasons of 2003/2004 and 2004/2005 to study the effect of application times and levels of nitrogen fertilizer (ammonium nitrate) on faba bean yield and its components Split plot design was used. The main plots were assigned to three nitrogen application time: 1-addition at sowing (T1), 2- addition at the first irrigation (T2), 3- addition at the second irrigation (T3). The sub plots were allotted to four nitrogen levels as follows 00%), 15(N15). 30(N30) and 45 (Nds) kg N fed". The efficiency of nitrogen application times on straw and biological yield of faba bean in both seasons were highly significant, The first treatment (Ti) gave the highest seed yields (1541 and 1624 kg fed") and straw yields (2763 and 2741 kg fed’) in the first and second seasons, respectively. While, the third treatment (T3) gave the lowest seed and straw yields in both seasons. Also, the efficiency of N—levels on seed yield, nitrogen. protein and phosphorus contents as well as 100 seeds weight were highly significant in both seasons. The interaction effects between nitrogen application times and nitrogen levels were obvious on the seed and straw yield, also on the protein, nitrogen and phosphorus contents of seeds and straw phosphorus content in both seasons, The contents of nitrogen and protein in straw yield in both seasons were significantly increased. The available so” nitrogen increased by increasing the levels of applied N-fertilizer in both seasons, Also, times of nitrogen application were efficacious on the amount of available soil nitrogen after harvest as follows T3>T2>T1. The highest estimated income values (LE) were obtained by the treatment of 30 kg N at sowing in both seasons.
