“…El contenido de proteína en soja de primera en una buena campaña (2016/2017) en Argentina fue de 36 % y en la de segunda de 37,5 %. En general, cuando los factores ambientales son favorables y se establece un elevado rendimiento en grano, la concentración de proteína en los granos disminuye (efecto de dilución) y aumenta la concentración de aceite en los granos (Cuniberti, 2017) La elección del genotipo y la fertilización nitrogenada surgen como herramientas para incrementar el porcentaje de proteína en los granos de soja (Di Mauro et al, 2023).…”

La soja es el principal cultivo de grano en Paraguay. Su producción avanza en el Chaco central y se requiere información sobre el comportamiento de nuevos cultivares que se adapten a la región. El objetivo fue analizar la productividad y adaptabilidad de cultivares de soja en secano en el Chaco central paraguayo. En Loma Plata (Cooperativa Chortitzer Ltda) se evaluaron a campo 25 líneas experimentales y 6 variedades comerciales (VC) en un diseño en bloques completos al azar con 3 repeticiones. La temporada (2019) fue calurosa en la etapa vegetativa y sufrió anegamiento en las etapas reproductivas. Se registró la fenología, el rendimiento y sus componentes y la composición de granos. Entre los cultivares, la duración de la etapa fenológica siembra-floración varió entre 30 y 50 días. El rendimiento se ubicó en el rango de 800 a 1600 kg/Ha, con diferencias significativas entre cultivares (p<0,0001). Las líneas 23, 9, 13, 6 y 25 fueron competitivas contra las mejores VC (VC6 y VC5). El rendimiento se asoció al número de granos (r=0,82). La composición de los granos fue estable, con 22,6-24,0 % de aceite y valores anormalmente bajos (< 28%) de proteína. Se concluye que hay líneas experimentales promisorias para el Chaco central, con rendimientos competitivos respecto a las variedades comerciales y que la línea 23 tiene elevado número de vainas y peso de grano, con adaptación al suelo con alta frecuencia de inundación. Su utilidad en sistemas de rotación en los arrozales chaqueños es un tema de interés para próximas investigaciones.

“…Furthermore, balanced foliar fertilisation positively influences plant physiology without negatively affecting the environment [18][19][20]. Bacilieri et al [21] and Di Mauro et al [22] report that the application of nutrients to the soil, leaves, or to the seed is a well-known treatment in the agro-techniques of many crops. However, depending on the species, fertilisation with specific elements is not always justified.…”

Legumes, due to their symbiosis with papillary bacteria, can receive nitrogen from the air. The remaining nutrients must be supplied in fertilisers, either soil or foliar. In the pot experiment, we recorded the responses of two soybean cultivars (Annushka, Pompei) to the foliar application of micronutrients (control, Zn, Fe, Cu, Mn, B, or Mo). The physiological properties were expressed as net photosynthetic rate (PN), intercellular CO2 concentration (Ci), transpiration rate (E), stomatal conductance (gs), maximum quantum yield of photosystem II (Fv/Fm), maximum quantum yield of primary photochemistry (Fv/F0), photosynthetic performance index (PI), and the development of soil plant analyses (SPAD), which were analysed. The effects of individual micronutrients on nodulation, plant growth, and condition were also investigated. Micronutrient fertilisation had a positive effect on plant fresh weight and no negative effect on plant condition. It was shown that elements such as B, Fe, and Mo had the most beneficial effect on nodulation compared to the control, regardless of the cultivar analysed. The application of single-component foliar fertilisers improved the physiological parameters of the plants. The relative chlorophyll content was most favourably affected by the application of Mn, B, and Mo in the Annushka cultivar, and Fe, Mn, and Mo in the Pompei cultivar. Similarly, in the case of chlorophyll fluorescence, the most stimulating effect was found for Mn and B, regardless of the cultivar. In the case of gas exchange, the application of Fe, Mo, and B for the Annushka cultivar and Cu for the Pompei cultivar had the most favourable effect on physiological measurements. The results obtained indicate that the foliar application of the evaluated micronutrients is justified in soybean cultivation and does not disturb the nodulation process.

“…According to Di Mauro et al (2023) considering the genetic and agronomic advances worldwide, soybean yield will continue to grow over time. Patil et al (2017) stated that in fact, protein is a key factor that determines the nutritional and economic value of soybeans.…”

This experiment investigated the effect of foliar fertilization on yield components, yield and protein content to 75 soybean genotypes from four maturity groups. The experiment took place within the Soybean Breeding Laboratory at Research and Development Station for Agriculture Turda (RDSA Turda) over the course of two years (2020, 2021). The experimental design was a complete randomized block with three replications in which three variants of fertilization were analyzed, and the application of foliar fertilizers was carried out in different stages of soybean vegetation. In general, if we refer to the yield, it is observed that most of the genotypes that reacted favorably to the application of foliar fertilization are with the Ff1 variant, on the other hand, for the protein content, it seems that the Ff2 foliar fertilization variant causes an increase in protein in most of the genotypes that they had a favorable reaction to foliar fertilization. Regarding the component elements of yield, the application of foliar fertilization variants does not greatly contribute to increasing their number, being directly related to the genotype but also the interaction between environment x genotype.
