Effect of biostimulant on yield characters of common bean cultivars under Southwestern Goiás conditions

Abstract

This study aimed to evaluate the effect of biostimulant positioning on common bean cultivars in the southwestern Goiás conditions. The experiment was conducted in the municipality of Mineiros-GO. The experimental design was a randomized block in factorial 6x3, corresponding to the positioning of the Triplus® biostimulator (R5, R5 + R8 and water) in six common bean cultivars (BRS Campeiro, BRS Esteio, BRS Estilo, BRS Marfim, BRS Notavel and BRS Perola) in 4 replicates. The following productive attributes were evaluated: number of pod, number total of grains, number of commercial grains, number of non-commercial grains, mass of commercial grains, thousand grains mass. There was a significant interaction between cultivar x biostimulant as well as the factors alone. At the end of the experiment, it was concluded that the positioning of the biostimulant via foliar in the R5 phenological phase provided the highest yields for all common bean cultivars, especially BRS Estilo (43.87 sc ha-1) and BRS Notavel (43.02 sc ha-1). Biostimulant applications at stage R5 promoted the best results for number of non-commercial grains, mass of commercial grains, thousand grains mass. In the three stratifications used in the dendrogram, it was possible to form two groups of genotypes. Number total of grains, number of commercial grains and number of pod positively correlate with yield.

Effect of fertilization with basalt powder and inoculation of Bradyrhizobium spp in common bean

“…The plant originates in South America and there are approximately 55 species, with the most cultivated and commercially produced group being carioca, characterized by its high levels of iron and protein in its composition. Common bean is one of the primary sources of carbohydrates, proteins, vitamins, and minerals (Ferreira et al, 2022;Paulino et al, 2022;Silva et al, 2023).…”

Enhanced understanding of anthracnose resistance in Michigan Dark Red Kidney common bean cultivar

“…Its two primary domestication centers are the Mesoamerican and Andean regions, which can be differentiated by several distinct traits, such as phaseolin types, molecular markers, morphological features, and isoenzymes (Gepts et al, 1988;Singh et al, 1991;Haley et al, 1994;Beebe et al, 2000;Ansari et al, 2004). Common beans are among the most significant legumes for human consumption ( Messa et al, 2019;Coêlho et al, 2020;Carvalho et al, 2021;Chimenez-Franzon et al, 2022;Ferreira et al, 2023;Silva et al, 2023). However, their productivity can be severely impacted by anthracnose, a disease caused by the fungus Colletotrichum lindemuthianum (Sacc.…”
