“…These results corroborate Foloni and Rosolem (2008), who verified higher soybean yields with applications of 90 kg ha -1 K2O. For Duarte et al (2016), the number of seeds per plant and grain yield increase linearly with increasing fertilizer doses.…”

The objective of this study was to find the best potassium dose to increase soybean yield, taking into account the economic viability of the crop in the studied region. Sixteen treatments of the interaction between potassium doses (0, 50, 100 and 150 kg ha-1) and application times (sowing, vegetative stage (V3), vegetative stage V3 + reproductive stage (R1) and reproductive stage). The experiment was set up in a randomized complete block design with four replications. Plant growth and production characteristics were analyzed and a preliminary analysis of variance was applied to check the significance of the interactions for each characteristic by Tukey’s test (α = 0.05). Subsequently, the regression analysis was performed using SAS software (2013). The economic analysis was made using the Monte Carlo methodology (Lima, 2008), and processed with the software @Risk 7 (PALISADE, 2016). Potassium fertilization was positive with increase in yield, but there was no direct relation with the application period. The 109 KCl ha-1 dose provided greater economic viability in soybean cultivation.

“…From the beginning of the 20th century until present, studies on soybean arrangements have substantially demonstrated the changes in plant plasticity and crop production (AGUDAMU & SHIRAIWA 2016, KUMAGAI & TAKAHASHI 2020, RAHMAN & HOSSAIN 2011, SHIBLES & WEBER 1966, WERNER et al 2021, WIGGANS 1939, as well as features directly linked to light interception efficiency (BOARD 2000) and radiation use efficiency (RUE) (PURCELL et al 2002). In this sense, one of the strategies that has been studied, aimed at better usage of light radiation, is the use of different plant populations combined with different spatial arrangements (DUARTE et al 2016, PURCELL et al 2002.…”

The arrangement of soybean plants defines their ability to recognize the environment and improve their abiotic and biotic interactions with it. This study aimed to evaluate the effect of planting arrangements associated to two distinct crop systems (high technological level or conventional crop level) for the soybean varieties 8473 RSF and AS 3730, to evaluate the plant performance and productivity in the field. A double factorial scheme was used with two varieties and six spatial arrangements. Two experiments were conducted during the 2017–2018 crop season: the first was based on standard cultivation of the Brazilian Cerrado (without irrigation systems and adequate fertilizer), whereas the second utilized high technology (irrigation systems and increased fertilizer). The morphophysiological parameters, normalized difference vegetation index (NDVI), leaf pigment content and crop yield parameters were evaluated. Our study pointed out the positive responses for both cultivated varieties and two technological levels adopted cultivated under equidistant arrangement and high density. The leaf area index, leaf pigment content, NDVI, and crop production showed substantial responses under different equidistant arrangements. Therefore, this procedure requires adjustments in the level of cultivation technology and identification of the most suitable soybean variety.

“…In this case, fertilizer application becomes efficiently when performed in summer crop [11]. On the other hand, regardless fertilizer application time, positive results were reported with increased fertilization levels for soybean, cultivated in medium to low fertility soils [12][13][14]. Increasing fertilizer levels has not been show gains in productivity, in high fertility soils [15].…”

System fertilization is characterized by partial or total fertilizer application at the predecessor crop; and it can be a viable practice to soybean crop. This study aimed to determine the fertilizer management and fertilizer levels for black oat-soybean cropping system, in high fertility soils and no-tillage system. The field trial was conducted in a bifactorial scheme, consisting of six environments, by combination of locations (Bom Sucesso do Sul -Paraná, Itapejara d'Oeste -Paraná) and fertilization management (all fertilization in black oat; splitting with 50% in black oat and 50% in soybean, all fertilization in soybean), and four fertilizer levels (0, 100, 200 and 300%) defined according to soil analysis and production expected. The evaluated traits were dry mass production, N, P and K nutrient accumulation of straw, dry mass remaining of black oat crop; and plant height, number of pods per plant, thousand grain weight, grain yield for soybean crop. Higher black oat dry mass production was observed at higher fertilization level. The fertilizer anticipation in black oat crop had better performance. Phosphorus and potassium accumulation increased linearly with fertilizer level increase. For N, the highest accumulated value occurred at the 200%, decreasing at the 300% of fertilizer level. The soybean crop had no influence in grain yield considering fertilization management, anticipation or splitting, and fertilizer levels. Thus, the system fertilization can be a viable practice, and favor black oat dry mass production and soybean development. HIGHLIGHTS All early soybean fertilization for black oat increase dry mass.  Higher black oat dry mass provides higher amount of nutrients to summer crops. Soybean grain yield is kept in system fertilization. 2 Zanella, Rodrigo; et al.
