Partitioning of dry matter, calcium, magnesium and sulfur in bean genotypes

Abstract

The study of the absorption rate and of final accumulation of nutrients allows 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 requiring as the bean plant, that information is still more valuable and must be obtained on the basis of the different genotypes, since a lot of their characteristics such the growth habit, can interfere on the results. That work was intended to evaluate, in four bean cultivars of different growth habits, the distribution of dry matter, Ca, Mg and S in different organs of the plant.
