Forage productivity of combined crops of seed oats, maize, and Sudanese sorghum with white lupine
Research aimed at the accumulation and effective use of nitrogen, its symbiotic fixation from the air by white lupine plants, by selecting the best cereal components, optimizing their ratio and methods of placement when growing in compatible crops under different fertilization systems in the Forest Steppe is insufficient. The purpose of this study was to establish the best cereal components, their ratio and methods of placement with white lupine when sowing in joint crops under different fertilizer systems to produce grass fodder in the Forest-Steppe of Ukraine. The following methods were used: field, laboratory, mathematical-statistical, calculation-comparative. It was established that the highest productivity on the background without fertilizers (4.21-4.86 t∙ha–1 of dry matter) was provided by single-species crops of maize and white lupine, as well as their combined crops, which were formed by continuous row and strip methods, which by 2.60-3.17 t∙ha–1 of dry matter or 1.8-2.6 times more compared to crops of oats and its mixture with white lupine and by 1.13-1.58 t·ha-1 or 1.4-1.5 times more compared to crops of Sudanese sorghum and its mixture with white lupine. Through the accumulation and use of symbiotic nitrogen fixation, the productivity of lupine-oat mixtures increased from 1.90 to 2.70-3.21 t∙ha–1 of dry mass or 1.4-1.7 times, and that of lupine-sorghum – from 3.17 to 3.43-3.47 or 1.1 times.
