Seleção de cultivares de feijão-comum em sistema de produção irrigado

Abstract

ABSTRACT In irrigated production systems, the common bean grain yield must reach high levels to maintain economic viability. In this context, management, like the selection of the most adapted cultivars, may be effective in obtaining high yields. Through a three-year experiment, it was aimed to select the common bean cultivars with the highest agronomic and technological performance in an irrigated production system and to determine the yield component that most interfered with common bean yield. The treatments consisted of eight common bean cultivars with indeterminate growth habit and from the pinto bean variety (carioca): ANFc 9, BRS Estilo, BRSMG Madrepérola, Pérola, IAC Alvorada, IAC Milênio, TAA Bola Cheia, and TAA Dama. IAC Milênio and IAC Alvorada had the highest agronomic performance for irrigated production systems, with grain yields up to 17% higher than other cultivars. The cultivars show little variation in the grain technological quality, meeting the culinary and nutritional qualities recommended for common bean. The ANFc 9 cultivar showed the highest crude protein content in grains (19%). The number of pods per plant is the yield component that most interferes with common bean grain yield, generating 86 kg ha-1 increments for each unitary increase. Therefore, the common bean cultivars selection in the irrigated production system is an effective management practice to increase common bean agronomic and quality performance.
