“…LIMA et al (2012) also commented that the setting of the sowing density is an important tool in the optimization of plant growth, biomass gain and grain production. SOARES et al (2015), in research conducted in Minas Gerais, confirmed that there is an interaction between the densities of sowing and soybean cultivars and showed that the population of 300 thousand plants per hectare is the most suitable for cultivation in the evaluated sites. Results obtained by LUDWIG et al (2011) also corroborate the existence of cultivars x population interaction.…”

Plants density in soybean cultivation is an important management practice to achieve high grain yield. In this way, the objective was to evaluate the agronomic traits and grain yield in soybean in different plant densities, in two locations in the south of Minas Gerais. The experimental design was in randomized blocks, arranged in a split plot design, with three replications. Plots were composed of four population densities (300, 400, 500 and 600 thousand plants per hectare) and the subplots were composed of six cultivars (‘BMX Força RR’, ‘CD 250 RR’, ‘FMT 08 - 60.346/1’, ‘NA 5909 RR’, ‘TMG 7161 RR’ and ‘V - TOP RR’) grown in Lavras and Inconfidentes, both in Minas Gerais. At the time of harvest was determined the plant height, lodging, insertion of the first pod, harvest index, number of pods per plant, number of grains, number of grains per pod and yield. Regardless of the soybean cultivar, the plant density of up to 600,000 per ha does not affect grain yield, plant height, lodging, harvest index, and number of grains per pod. The cultivars ‘V-TOP RR’ and ‘BMX FORÇA RR’ showed high grain yield and good agronomic traits in Lavras and Incofidentes.

“…The number of grain per pod and the grain harvest index were not significantly influencied by cultivars (Table 2). Soares et al (2015a) and Felisberto et al (2015) observed an effect of cultivars on the agronomic traits evaluated. The authors affirm that it was expected, since cultivars have different genetic background, growth habit, maturation group and other characteristics providing variations.…”

In the last decades, the Brazilian soy productive chain has passed through a transformation process in which the yield, efficiency, profitability, economic and environmental sustainability are very important issues. In this context, the introduction of microorganisms has provided an increase in grains yield. The objective of this study was to evaluate the inoculation of Azospirillum brasilense associated with Bradyrhizobium japonicum in agronomic traits and the soybean productivity. The experiment was conducted in randomized blocks in 4 × 2 factorial, with four cultivars (Anta 82 RR ® , BRS Favorita RR ® , BRS 780 RR ® , BRS 820 RR ® ) and two treatments with A. brasilense (inoculated and non-inoculated) with three replications in two growing seasons. The following traits were evaluated: plant height, shoot dry biomass, chlorophyll content, leaf nitrogen content at flowering; and at harvest, the plant height, the insertion of the first pod, number of pods per plant, number of grains per pod, thousand-grain weight , grain yield, and grain harvest index were evaluated. There was a significant effect of growing seasons and cultivars in an isolated way and their interaction in most traits. The conditions in which the study was conducted, with or without inoculation of A. brasilense associated with B. japonicum do not affect the agronomic traits and grain yield in RR ® soybean cultivars.

“…This behavior is due to a framework of these three growth habit groups: determinate, indeterminate, and semideterminate (Tian et al, 2010;Soares et al, 2015). Knowledge of these characteristics influences population distribution of the crop in the field, so the best space arrangement should enable high agricultural productivity (Board and Kahlon, 2013).…”
