Seed production of bush snap beans genotypes in conventional and organic systems

Abstract

Snap beans are one of the ten most consumed vegetables in Brazil, and there are few cultivars available in the Brazilian market. This study aimed to evaluate the seed yield of 20 snap beans genotypes under conventional and organic systems under Brazilian Cerrado conditions. Plant height, number of seeds per pod, weight of 100 seeds and yield were evaluated. For plant height and number of seeds per pod, the 20 genotypes were equal in the conventional cultivation system. In the organic system, the 20 genotypes formed two distinct groups regarding these variables. In the conventional system there were no significant differences between genotypes regarding the weight of 100 seeds, the mean mass in this system was 19.08 g, but there were differences in the organic system. Regarding yield, there was significant difference between the genotypes for both cultivation systems, organic and convetional. Production of snap bean cultivars in the organic system was shown as viable and promising. The genotypes Amarelo Japonês, Hab 1 and Tendergreen Improved stood out among the most productive in both systems.

Bush Snap Bean Genotypes Under Conventional and Organic Cultivation

“…2022. Néri et al (2020) obtained results for seed production in snap bean genotypes in organic and conventional systems, evaluating the identical genotypes used in this study, observed that the Amarelo Japonês, Hab 1, and Tendergreen Improved genotypes had good productive performance in both cultivation systems. In conventional cultivation, Commodore Improved, Festina, and Jade stood out, and in the organic system, Delinel, Hab 39, Improved Gold Wash, Royal Burgundy, Slenderwash, and Tendergreen.…”

“…According to Néri et al (2020), although the introduction of bush cultivars in Brazil is recent, their demand has grown since the 1980s, and the availability of appropriate cultivars is of fundamental importance, both for organic and conventional cultivation. One issue that permeates agricultural production debates is the focus on sustainability, emphasizing organic and agroecological production systems.…”

“…Because they have specific characteristics, different production systems influence crops differently (Gomes et al, 2017). In this sense, Néri et al (2020) evaluated, in Anápolis, regarding seed production, 20 bush snap bean genotypes in conventional and organic systems, with most genotypes being more productive in the organic system. Portal et al (2018), studying 20 bean genotypes of indeterminate growth, in the same location, of both systems, also obtained better productive performance in the organic system.…”
