INFLUENCE OF DIFFERENT DOSES OF PHOSPHORUS ON THE VEGETATIVE DEVELOPMENT OF BEANS (PHASEOLUS VULGARIS L)

Abstract

ABSTRACT: Common beans are one of the most cultivated and exported legumes in Brazil, contributing significantly to the country's agricultural economy. Considering the presence of issues related to natural fertility in tropical soils, it is essential to resort to the use of fertilizers in order to ensure satisfactory agricultural performance. The objective of this work was to evaluate the effect of different doses of phosphorus on the development of common beans. The experiment was conducted in a pot under field conditions in the city of Cacoal/RO. The experimental design used was completely randomized, with four doses of phosphorus (P²O⁵): 0, 40, 80, 120 and 160 kg ha^-1. Plant height, number of leaves, fresh and dry mass of the aerial part were evaluated. The data were subjected to analysis of variance and the means were compared using the Tukey test, with a significance level of 5%. The P²O⁵ doses tested did not significantly influence the analyzed variables.
