Boron/Nitrogen Interaction Effect on Growth and Yield of Faba Bean Plants Grown under Sandy Soil Conditions

摘要

A field study was conducted during the two winter seasons of 2000/2001 and 2001/2002 with faba bean ( Vicia faba L. cv. Giza 717) plants grown on sandy soil of Ismailia governorate, Egypt. The study aimed at determining the response of faba bean plants to different nitrogen levels applied to soil in the presence or absence of different doses of boron foliar treatments. Results declared that boronitrogen synergetic effect additively increased nutrient content within faba bean plant tissues. Boron foliar fertilization in a concentration of 25-50 ppm in the spray solution, in combination with 40 kg nitrogen/fed as soil treatment has significantly increased plant height, leaf area, total dry weight, number of pods, number of seeds per pod, seed yield . However, seed protein and carbohydrate proper accumulation required higher doses.
