Bush Snap Bean Genotypes Under Conventional and Organic Cultivation

Abstract

Snap bean is a species widely cultivated in Goiás, in which cultivars of indeterminate growth are used in a staking system. Considering the high cost of staking and the unavailability of a workforce, there has been a demand for bush cultivars, but little is available on the market. In this sense, the present study was developed to evaluate, in 2016, under the conventional and organic cultivation systems, in Anápolis-GO, the behavior of 20 bush snap bean genotypes. The experimental design was randomized blocks, with 20 treatments and three replications. There was a significant interaction between genotypes and cultivation systems for vigor, average pod mass, number of pods per plant, and pod yield, evidencing that the types of cultivation, organic and conventional, interfered with the response of these variables. Although the Commodore Improved cultivar has excelled in pod yield in the conventional system, all genotypes were suitable for organic production. Hab 39, Improved Gold Wax, Kentucky Wonder Bush, Provider, Stringless Green, and Tendergreen genotypes are unsuitable for the conventional production system.

Common Bean Productivity and Micronutrients in the Soil–Plant System under Residual Applications of Composted Sewage Sludge

“…The estimated production was around 1.43 million tons from the planted area of 1.38 million hectares in 2021/2022, reflecting an increase in productivity [2]. Beans are produced and imported in many countries, as they are one of the main sources of protein, rich in macro-and micronutrients, such as K, Mg, Fe, and Zn, among other benefits [3,4].…”

Análise econômica do uso de bioestimulantes na cultura do feijão em diferentes métodos de aplicação

“…O feijoeiro (Phaseolus vulgaris L.) é uma das culturas que apresenta grande importância na economia Brasileira, pois seu valor nutricional, apresenta quantidades significativas de proteínas, carboidratos e aminoácidos que são fundamentais na dieta alimentar em vários países, principalmente na América do Sul e Central (Santos et al, 2016;Araújo et al, 2018;Soares et al, 2019;Vidal et al, 2022). Com uma estimativa de produção média de 1.06 milhões de toneladas (Rodrigues et al, 2018;Conab, 2021), o Brasil se destaca entre os maiores produtores mundiais, no entanto, ainda apresenta baixa produtividade visto que, seu potencial produtivo pode superar 3.500 kg ha -1 (Aserse et al, 2019), devido a diversos fatores, entre eles à baixa fertilidade natural dos solos (Lopes et al, 2022).…”
