FITOSSANIDADE E ASPECTOS MORFOAGRONÔMICOS DE CULTIVARES DE FEIJÃO COMUM (Phaseolus vulgaris) e FEIJÃO DE CORDA (Vigna unguiculata)

Abstract

The bean is one of the most important crops in Brazil, among the biotic factors limiting the productive potential, the plant health and the morphoagronomic aspects of the bean cultivars stand out. Efficient phytosanitary management is one of the main challenges faced by Brazilian producers, due to the large number of diseases that affect the culture and favorable environments and the lack of preventive phytosanitary management. The genetic improvement seeks in the great genetic diversity, to improve the quantitative characters to increase the morphoagronomic aspects, consequently raising the productive potential. A study was carried out at the RC Cruz Experimental Station at Fazenda Esmeralda in the municipality of Ipameri-GO, with the objective of evaluating the behavior of bean cultivars in relation to phytosanitary and morphoagronomic aspects, among twenty-seven bean cultivars in the field. The experiment was carried out in a randomized block design, in a 27 x 4 statistical scheme, with twenty-eight bean cultivars with four replications. They were concluded, with 31, 47, 61 and 76 DAP of the cultivars, analyzing: plant height, number of pods per plant, number of grains per plant, average number of grains per plant, number of nodes per plant, mass of grains per plant, infection rate and phytosanitary severity. The variables analyzed were submitted to parametric and nonparametric hypothesis tests and multivariate analysis. From the results obtained it was found that seventeen cultivars were resistant and ten were susceptible to phytosanitary complexes, and as cultivars IPR Uirapuru, BRS FC 104, IAC Sintonia and IAC Millenium of generation as grain masses per plant.
