Abstract

There are some controversies according to soil system preparation effects varying from no-tillage system to conventional one. This work aims at studying the bean plant in two aspects: the spatial variability of grains and straw yield in Oxisol under conventional tillage (CT) and no-tillage (NT) systems. It was carried out at Ilha Solteira Experimental Station of Unesp (Fazenda de Ensino e Pesquisa da Faculdade de Engenharia de Ilha Solteira - FEIS)- in Selvíria, Mato Grosso do Sul State, Brazil. The geostatistics grids consisted of 120 points for CT and 135 points for NT. The parameters of the studied culture showed spatial dependence structure with moderate dependence for CT and a very strong one for NT. The highest range found was 26.1 m for the CT under the NT. The different soil preparation systems did not influence bean productivity.
