Effects of sowing dates and urea foliar application on growth and seed yield of determinate faba bean ( Vicia faba L. ) under Egyptian Conditions

摘要

Two field experiments were conducted during the two winter seasons of 1999/2000 and 2000/2001 in the Experimental Farm, of the National Research Center, A at Shalakan, Kaluobia Govemorte . The experiment aimed to study the effect of sowing date 15 October, 1 November and 15 November and urea foliar application at rate of (0,1,2 and 3 percent ) on growth and yield of determinate faba bean (Vicia faba L.) (FLIP-87-117). Results indicate that early sowing resulted in greater growth and yield than latersowing yield during the two growing seasons , but this effects was larger in 1999/2000 than 2000/2001. Growth , yield and protein content of faba bean were higher when faba bean was sprayed by 2 percent urea than 0 , 1 or 2 percent in both seasons but this effect was larger in 1999/2000 than 2000/2001. 100 - seed weight, yield ton/ha and harvest index were higher when utilize each sowing date with 2 percent urea as foliar fertilization.
