Efeitos de cinco lâminas de água e três doses de adubação nitrogenada em cobertura, sobre o crescimento do feijoeiro (Phaseolus vulgaris L.).

Abstract

In order to use the growth analysis to analyse the behavior of the bean plant under different conditions, it was conducted an experiment at FCA/UNESP/BOTUCATU/ SP, using the line-source sprinKler, resulting in the combination of five water levels and three doses of nitrogen topdressing. It was calcutated the leaf area index (IAF) and the total dry material (MST) and it was adjusted their curves according to the time (days after the emergency - DAE). We can observe that throught the growth analysis it’s possible to explain the growth differences among the various treatments.
