Soybean seed coating with Rhizobium inoculum is a conventional, yet expensive, practice that may result in seed damage and reduced productivity. To address these issues, in this study we developed and installed a spraying novel system on row planters that directly sprays the inoculum solution onto the seeds and furrows. We optimized the system by using the response surface methodology and a central composite design with 20 tests to evaluate the effects of the forward speed, flow rate, and spraying angle on the seed coverage. Our results show that all three variables have significant effects on seed coverage, and we obtained maximum and average seed coverages of 95.38% (experimental) or 96% (predicted), respectively. We developed a quadratic model that accurately predicts the seed coverage as a function of the forward speed, flow rate, and spraying angle, achieving a coefficient of determination of 97.24%. The optimal settings for the best seed coverage were determined to be a forward speed of 4.65 km/h, a nozzle flow rate of 400 mL/min, and a nozzle angle of 46°. Our study presents a practical and cost-effective solution for improving soybean seed coverage and enhancing crop productivity.

Background: The main advantage of leguminous plants is the ability to self-supply atmospheric nitrogen through symbiosis with the bacterium Bradyrhizobium japonicum. Therefore, seed inoculation with microbiological preparations is often used in agricultural practice to increase nodulation on the roots. Methods: A field experiment was conducted to examine the effect of commercial preparations or coated seeds containing Bradyrhizobium japonicum on soybean yield and quality. The experiment was performed in four replicates in a randomized block design. The seeds were inoculated using commercial preparations (HiStick® Soy, Nitragina®, TURBOSOY®, PRIMSEED® BIOM Soja, bi soya, RHIZOBIUM SOJA), which were mixed with the seeds on the day of sowing. Sowing coated seeds using the “Fix Fertig” technology did not require seed inoculation before sowing. Result: It has been demonstrated that HiStick® Soy and TURBOSOY® exerted the most beneficial effect on nodulation, SPAD index, number of pods per plant, TSW and yield. The preparation RHIZOBIUM SOY was also highly effective. Sowing inoculated or coated seeds positively affected the protein content of the seeds but the fat content was the highest in the control seeds. It has been demonstrated that the weather conditions in individual years modified the investigated parameters.

“…However, the main source of this element should be biologically fixed nitrogen. The experiments carried out by Jarecki [17] showed that seed inoculation had a positive effect on nodulation and physiological parameters of soybean plants. However, the farmer must carry out such treatment on his own farm, which is costly and time-consuming.…”

Soybean is one of the most important legumes in the world, and its advantages and disadvantages are well known. As a result of symbiosis with the bacterium Bradyrhizobium japonicum, soybean can assimilate nitrogen from the air and is therefore not fertilized with this element, or if it is, only at small doses. In soybean agriculture practice, an important treatment is the inoculation of seeds with symbiotic bacteria and optimal fertilization with selected nutrients. Therefore, a three-year (2019–2021) field experiment was carried out to investigate the effects of soybean in the field to a seed Rhizobium inoculation or coating and molybdenum foliar fertilization. There were no significant interactions between the tested treatments over the years. It was demonstrated that the best variant was seed inoculation before sowing in combination with foliar molybdenum application. As a result of this treatment, a significant increase in nodulation, soil plant analysis development (SPAD) index, leaf area index (LAI) and seed yield (by 0.61 t·ha−1) was obtained compared to the control. In addition, the content of total protein in the seeds increased, while the content of crude fat decreased, which significantly modified the yield of both components. Sowing coated seeds in the Fix Fertig technology was less effective compared to inoculation, but it was significantly better than that in the control. Coating seeds with B. japonicum, in combination with foliar fertilization with molybdenum, could be recommended for agricultural practice, which was confirmed by economic calculations. Future experiments will assess the soybean’s response to seed inoculation or coating and fertilization with other micronutrients.
