Crescimento, fotossintese e eficiencia do uso de nitrogenio em milho, feijao e mandioca submetidos a dois niveis de N no solo

Growth and N uptake in pot-grown maize, beans, and cassava were evaluated under 2 levels of soil N at CIAT-Palmira (Colombia). The lower amount of the element reduced its uptake by the 3 species, resulting in lower tissue concn., especially in the leaves. Under low N, DM accumulation was also reduce...
