Resposta da cultura do feijão (Phaseolus vulgaris L.) `à aplicação de calcário, adubo nitrogenado e fosfatado, em municípios da Zona da Mata, Minas Gerais

Resumo

Four field experiments were laid out in the same soil type, on locations at Viçosa (two trials), Visconde do Rio Branco and São Pedro dos Ferros, in the Zona da Mata, Minas Gerais State, during two growing seasons. The objective was to study the effect of lame, phosphorus and nitrogen on grain yield by dry beans (Phaseolus vulgaris L.)

At Viçosa, the residual effect cf the fertilizers and lime were assessed throughout a second planting on the same plots, without further addition of fertilizers or lime. 

In Viçosa's first planting, the three factors studied increased the dry beans yield significantly. Nitrogen ranked first, followed by phosphorus and lime. The nitrogenous fertilizer efficiency increased with the increase in lime levels. Dry beans responded to the residual lime in Viçosa's second planting.

At São Pedro dos Ferros lime was the only factor to increase dry beans yield significantly.

Response of dry bean plants to nitrogen and phosphorus at Visconde do Rio Branco were significant, although other factors appeared to interact rendering inconclusive results
