Produtividade de cultivar de soja (Neo 750 ipro) em diferentes densidades de semeio

Abstract

Soybean (Glycine max) belongs to the Fabaceae family, commonly known as legumes, as its seeds are formed inside the pods or legumes, which is the typical fruit of this plant family. The increase in productivity of soybeans planted in narrow rows (50 cm or less) compared to those planted in conventional rows (60 cm or more) often exceeds 10%. Thus, the objective of this research is to analyze the productivity of soybean cultivars with determined growth in different row spacing and plant densities. Plants grow more in dense row spacing than in less dense row spacing. Soybean plants at higher sowing densities grew more, so they proposed that at smaller spacings between rows it is necessary to reduce the number of plants per meter in the rows. The significant effect of the treatments was evidenced in the parameters number of pods and number of pods with two and three grains. Note that the treatment with 11 plants per linear meter has a higher average compared to the other treatments. The results indicate that a row spacing of 50 cm with plant spacing of 5 cm within a row can be used for high productivity and lower weed infestation of early and medium maturing soybean varieties under rainfed agriculture in the agroecological zone.
