Amany M. Sallam(1) and Jacklin G. Sadek(2)( 2012). IMPACT OF MOLYBDENUM AND BORON AS FOLIAR APPLICATION ON GROWTH, YIELD, SOME CHEMICAL COMPOSITION AND SEED QUALITY OF FABA BEAN (VICIA FABA L.)Minufiya J. Agric. Res. Vol.37 No. 4(2):1069-1086
Abstract: Two fields experiments were conducted during two successive seasons in 2010/2011 and 2011/ 2012 at Kafr EL_Zayiat Center, Gharbia Governorate, to study the effect of foliar application of two micro-nutrients, molybdenum and boron on Faba bean variety Giza 2. Faba bean plants were sprayed two times with different levels of molybdenum (0.0, 10 and 20 mg/l), likewise different rates of boron (0.0, 100 and 200 mg/l) either singly or together. First spray was after 45 days from sowing and the second after 60 days from sowing. The obtained data showed the positive effect of high rates of such nutrients (20 and 200 mg/l), on fresh and dry weights of stems, leaves, roots and whole plants. Roots were the most organs affected by such nutrients after 90 days from sowing. Significant increases in faba bean yield and yield components was occurred. The percentage increases in seed yield were19.33 and 19.82%, respectively for the first season, beside, 20.26 and 20.75%, at a respective order for the second season. Corresponding significant increases in macronutrients (nitrogen, phosphorus and potassium), molybdenum and boron concentrations, also its uptake in seeds, and both of crude protein and protein yield and total carbohydrates in such organ for two seasons were observed. Such increases were a companied by corresponding significant decreases for such nutrients in straw for two growing seasons. In general significant increases in germination percent, shoots length, radical length, seedling fresh weights, seedling dry weights and EC for two seasons for Giza 2 variety were indicated. The obtained data declared that the superior interaction effect was recorded for plants received a combined treatment of 20 mg/l Mo+ 200 mg/l B for all studied characters for Giza 2 cultivar.
