Efeito da dose de nitrogênio, lâmina de irrigação e uniformidade de distribuição da água na maximização do lucro do feijoeiro (Phaseolus vulgaris L.).

Abstract

This paper aims to quantify the influence of the nitrogen levels, irrigation depths and water application uniformity on bean yield and profit. It was focused two situations applied producers with fixed and semi-fixed sprinkler system and two others applied producers with center pivot system presenting different uniformity levels. It was considered two prices received by producers, 0,5830 and 0,4057 US$/kg. The economics levels of the production factors proportioned attractive profits when the bean price was 0,5830 US$/kg and damage when the bean price was 0,4057 US$/kg.
