Abstract

Two varieties of Vigna sinensis, "dorminhoco" and "pitiuba", were grown in nutrient solution till the end of the life cycle and then analysed in order to gain information about their needs for macro and micronutrients. The following has been found: (1) both varieties have the same needs; (2) production of 1 ton of beans requires the following quantities of macro (kg) and micronutrients (g): N - 76, P - 4, K - 85, Ca - 50, Mg - 13, S - 6. B - 320, Cu - 20, Fe - 1855, Mn-162, Mo - 7 and Zn - 89. (3) a comparison with data in the literature has shown that Vigna presents a higher demand for B and Fe than soybean.
