Cultivo de feijão-vagem em diferentes espaçamentos na fronteira oeste do Rio Grande do Sul

Abstract

Pod bean belonging to the genus Phaseolus and originating in Central America is a vegetable known for being consumed together with its pods and grains, being rich in fiber, mineral salts, vitamins and antioxidants; where the species with determined growth is characterized by being an annual plant with a cycle of 60 to 65 days and with a smaller size, which allows mechanized harvesting and eliminates the need for staking. Plant spacing is among the main crop managements, where the plant population can directly affect their development and consequently their production, in addition to interfering with the maximum use of the area. The objective of this work was to evaluate the productivity and production of snap bean cultivated in different spacings, in the western border of Rio Grande do Sul, being carried out five treatments of 0.20 m, 0.30 m, 0.40 m, 0, 50 m and 0.60 m between plants, being evaluated number of pods, number of grains per pod, pod weight, yield, pod thickness and length. The spacings of 0.20 m and 0.30 m were the ones that presented the best results in terms of productivity, while the size of the pods only treated 0.40 m differed from the others. The smallest spacings evaluated of 0.20 and 0.30 m between plants were the ones that presented the best results regarding the productivity of low-sized snap bean noodles, in the cultivation conditions of the western frontier of Rio Grande do Sul. The different spacings used in this work for the cultivation of short-sized snap bean noodles do not interfere in the number of pods and thickness of the pods. As for pod length, number of grains per plant and production, the spacing of 0.40 m was the only one that differed statistically negatively. Thus, it is understood that, as it does not interfere in the thickness and length of the pods, in addition to presenting greater productivity, the spacings of 0.20 and 0.30 m were the best.
