Abstract
Two field experiments were conducted at the experimental farm of Tag ELEZZ station, Dakahlia Governorate, dunng 2003/2004 and 2004/2005 seasons. The effect of three nitrogen sources (urea ammonium nitrate and arnrnoniu-n sulphate), phosphorien, citreen and control as well as their interaction on grovVth, yield, yield components and macro & micro nutrients uptake of three faba bean cultivars namely (Sakha 1, Giza 3 and Giza 2) were studied A split-split plot design with four replicates were used The main findings could be summarized as follows
1- Sakha 1 cultivar surpassed Giza 3 and Giza 2 in seed weiqht/plant 100-seed weight and seed yield ardab/ted and on Giza 3 in number of branches/plant in the two seasons. but Giza 3 surpassed on Sakha 1 and Giza 2 on plant height arid straw yield.
2- Urea Significantly increased the plant height, number of pods/pi;:.,,: ;n the t,'IO seasons, and surpassed on the number of branched/plant. seed weigl,( ton/plant and seed field (ardOlblfed). in the first season.
3- Phosphorien gave the highly significant increase In number of branches/plant, number of pods/plant. seed weight/plant. 100-seed weight (g) seed yield (ardab/fed) And straw yield (ton/fed). in the two seasons compared with the citreen and control
4- The mteraction between faba bean cuttivars and nitrogen sources had a significant effect on plant height (cm). number of pods/plant, seed weight/plant and straw Yield (ton/fed). In the two seasons and the increased In 100-seed weight In the first seasons only and significantly increased in seed yield/fed, In the second season
5· Planting sakha 1 cultrvar and fertilizing with 20 kg Nlfed, and 1000 g/phosphofien from phosphorern may be the recommended treatment to improve the productivity of faba bean under the condition of the present study.
6- Giza 3 gave the highest values for P uptake (11.74 kg fed') and Mn uptake (14 2 9 fed') as the average of both seasons. While Sakha 1 gave the highest uptake for K (2891 kg fed .), while Giza 2 for N (35.43 kg fed") and Fe uptake (93.49 g fed')
7· Phosphorien as a biofertilizer gave the r.ighest values for N, p. and K uptake by plant respectively in both seasons.
8- It IS noticed that, the interactions effect between all treatments wr h N. P. K, Fe. Zn and Mn upta'~e by faba bean plants were highly Significant in both seasons
