6.1. The uptake of macronutrients by bean plants was studied under field conditions. It was shownthat higher production of dry matter was obtained when the crop was 56 days old. Total amounts absorved were, in kg/ha: N-101, P-9, K-93, Ca-54, Mg-18 and S-25. 6.2. When grgown in nutrient solution symptoms of deficiency were observed tor all nutrients under study. Anatomical lesions within the leaf tissue were also observed, the chloroplasts being particularly affected. The following leaf levels of elements in the dry leaves characterize conditions of deficiency: N-1.54%, P-0.13%, K-0,93%, Ca-0.42%, Mg-0.48%, S-0.70%.Downloads
