Desempenho de cultivares de feijão em alta tecnologia

Abstract

The bean Phaseolus vulgaris L. is one of the foods that are part of the basic basket of Brazilians, as a source of protein as well as starch and dietary fiber. Brazil has international prominence, being in the ranking of the largest producers, at the national level, Paraná is the largest producer of the legume. Several factors directly affect the yield of the cultivar, mainly in relation to the attack of pests, diseases and effects caused by nutritional deficiencies. This work aims to evaluate common bean cultivars under high investment conditions for the Southwest of the state of Paraná, which was carried out in the municipality of Pato Branco - PR, estimating yield, number of pods per plant (NVP), number of grains per pod (NGV), density (DENS), thousand grain weight (PMG) and plant height. The experiment was conducted in the experimental area of the Federal Technological University of Paraná (UTFPR). Sowing took place in the 2022/2023 season, in October, in a randomized block design. Analysis of variance (ANOVA) and means were compared using the Skott-Knott test at a 5% error probability level. The highest yields were obtained by the cultivars IAC Netuno, BRS Esteio and IAC 1849. The number of grains per pod was important for increasing the yield of the BRS ESTEIO cultivar. It was observed that in relation to the weight of a thousand grains and plant height, it was higher for the ANFC9 cultivar, but it did not influence the increase in yield.
