The purpose of the work is to identify pairs of varietal strains with a high symbiosis effect for the development of new measures in the technology of growing different precocious soybean varieties on irrigated lands of the southern steppe of Ukraine. Research methods - field agronomic research on irrigated lands with laboratory analysis in a certified agrochemical laboratory, statistical processing of the results and economic evaluation of agronomic methods of growing crops. Elements of the technology of growing new-maturing breeding varieties of new generation on dark-chestnut soils of the Southern Steppe subzone under irrigation have been developed. The structure of the crop and seed productivity of the ultra-early-maturing variety Dion and the middle-early variety Aratta depending on the pre-sowing inoculation of seeds with nodule and endophytic bacteria on the irrigated lands of the southern steppe of Ukraine were established. Pre-sowing inoculation of seeds with nodule and endophytic bacteria, in comparison with control variants, contributed to the increase of yield of ultra-early variety Diona by 0.37–0.71 t / ha and medium-early variety Aratta by 0.31–0.88 t / ha.   Product Description popup.authors Halchenko Nataliia M Goloborodko Stanislav P Dubynska Olena D Levenets Tetiana P Tyshchenko Andrii V popup.nrat_date 2021-01-05 Close
