| Title : | THE EFFECT OF RHIZOGUMIN ON NODULATION; PRODUCTIVITY AND STRESS RESISTANCE OF SOYBEAN (Glycine max) |
| Abstract : | This study investigates the effectiveness of biological preparations in soybean (Glycine max L.) cultivation technology; a key crop due to its high protein content and ability to improve soil fertility through nitrogen fixation. Particular attention was paid to the inoculant Rhizogumin; which contains effective microorganisms that enhance the physiological state of plants. The experiment was two-factorial; involving the application of inoculation and foliar treatments. The obtained results demonstrated that pre-sowing seed treatment with Rhizogumin significantly increased the number and mass of nodules on soybean roots at all developmental stages; indicating successful intensification of symbiotic activity. The best nodulation indicators were observed in variants with pre-sowing inoculation; especially when combined with complex foliar treatments. This approach also positively influenced the formation of soybean yield structure components; particularly increasing the number of pods and seeds per plant; confirming the synergistic effect of the complex treatment. The study emphasizes that while inoculation and foliar treatments significantly improve key physiological indicators and soybean productivity components; the effectiveness of their impact on yield can be negated by abiotic stresses. Pre-sowing seed treatment with Rhizogumin significantly increased crop productivity. Without additional treatments; the yield was 3.43 t ha-1; which is 0.19 t ha-1 (5.9%) more than in the control without drugs. Treatment in the budding phase –3.49 t ha-1; an increase of +0.25 t ha-1 (7.7%); in the grain filling phase –3.43 t ha-1; at the level of a single effect of the drug (pre-sowing seed treatment with Rhizogumin). The highest yield was provided by the combined application (budding + grain filling) –3.56 t ha-1; which exceeded the control by 0.32 t ha-1or 9.9%. These findings highlight the need for further research into the interaction of biological preparations with soybean varietal characteristics under changing climatic conditions; as well as the development of integrated strategies aimed at minimizing the impact of stress factors to ensure consistently high yields. |
