ACCUMULATION OF MACRONUTRIENTS BY DIFFERENT COMMON BEAN CULTIVARS GROWN IN DIFFERENT PLANT DENSITIES IN CONVENTIONAL CROP SYSTEM

摘要

The aim of the current study was to follow the accumulation of macronutrients throughout the crop cycle in different cultivars of common bean with carioca seed type, grown under different plant densities in field experiments using a conventional cropping system. The experimental design was randomized blocks with three replications and a 4x5 factorial scheme, involving four bean cultivars (Table 1) and five plant densities (75, 145, 215, 285 and 355 thousand plants.ha~(-1)). The soil preparation was carried out by one operation with plow and two operations with harrow.
