Partitioning of dry matter, nitrogen, phosphorus and potassium in bean genotypes

Abstract

The study of the absorption rate and of the final accumulation of nutrients enables us to know the amounts of absorbed nutrients and the relative absorption, supplying basic information to the improvement of fertilizer application. In short cycle species, with little deep roots and highly demanding such as the bean plant, that information is further valuable and must be obtained on the basis of different genotypes, since a lot of their characteristics such as growth habit, may impact on the results. This work was intended to evaluate, in four bean plants of different growth habits, the distribution of dry matter, N, P and K in different organs of the plant.
