The Impact of Foliar Fertilization on the Physiological Parameters, Yield, and Quality Indices of the Soybean Crop

Presented research was carried out in 2021 and 2022 on the Felix soybean variety at Agricultural Research Development Station Turda, located Transylvanian Plain, Romania. In this experiment, complex fertilizer NPK 20:20:0 applied as a basic dose of 200 kg ha−1 sowing stage, to which foliar Agro Argentum Forte treatment added different doses application stages. The main purpose study identify suitable stages cultivation for effective vegetative development, yield, quality purposes. impacts fertilization system climatic conditions physiological parameters, assimilation, were evaluated. Technology showed that parameters positively influenced, following with Forte, average assimilation values recorded above 23.0 μmol CO2 m−2s−1 year 22.4 2022. Soybean crop influenced by fertilizers phases growth obtaining higher yields, well protein oil content. yield indices (protein, oil, mass thousand seeds) than variants treated compared control, resulting an improvement seed 3560 ha−1, while saw lower 1805 ha−1. mineral combination had significantly positive impact indicators seeds. highest yields achieved when early pod formation stage.
