PROJECT - SELECTION OF BEAN CULTIVAR (Phaseolus vulgaris L.) TO SOIL ACIDITY TOLERANCE

摘要

Exactly with the development of Brazilian agriculture, one of the constraints to the agricultural exploration is soil acidity, as much in traditionally cultivated soil as in new areas in agricultural expansion. Brazilian researchers have been esteemedthat 80% of Brazilian soil are acid, presenting raised aluminum concentration and, in lesser scale, iron and manganese. These elements harm the development of crops with consequences in such a way in the top plant how much in root system. In the root, where the plant tissue keeps in direct contact with the soil acidity, the low plant development harms the absorption of the majority of mineral nutrients.
