ANÁLISE DE PRODUTIVIDADE DA CULTIVAR BRASMAX ATAQUE I2X SOBB DIFERENTES POPULAÇÕES

Abstract

Soy is considered a crop with high economic importance. Through productivity studies, it became possible to understand the production components, such as: number of pods/plant, number of grains per pod, grain weight and plant population per unit area. Any change that occurs during the crop cycle will result in changes in productivity. The objective was to evaluate the productivity of the cultivar 81IX82RSF I2X as a function of different plant populations. The experiment was conducted from December/21 to April/22 in the municipality of Morrinhos, in the southern region of Goiás. Four treatments were performed, with four repetitions. The treatments were tested with four populations: 168,000, 240,000, 300,000 and 340,000 plants per hectare. The evaluated parameters were: pods per plant, number of grains per pod, thousand seed weight, plant height, plant diameter, number of nodes and productivity. Through the data analyzed in the statistics program Assistat 7.7, it was possible to observe that there was a statistical difference only for the variable pods per plant. Because the variables do not differ from each other, it is recommended that the producer use smaller populations, seeking to reduce seed costs.
