| Summary: | Background. The relevance of study is due to realization the productive potential of remontant corn and sugar sorghum and diversification field feed production in the Central region of Russia.
Purpose. The aim of this work was to identify the effectiveness of cultivation and use remontant hybrids of corn and sugar sorghum in conditions of the Bryansk region.
Materials and methods. The objects were 6 remontant (stay green) hybrids of corn on different ecological and geographical origin, 4 domestic varieties of sugar sorghum and 10 varieties of sorghum from Lidea. Laboratory-field and statistical research methods were used.
Results. High-yielding hybrids of remontant corn Voronezhsky 175 ACV, Creative, LG 3285 have been identified and providing more than 78-79 t/ha of green mass or 21.1-22.3 t of dry matter and grain up to 8.0 t/ha. The yield of aboveground mass sorghum varieties Listvenit and Sazhen amounted to more than 60 t/ha or up to 15.0 t of dry matter. Sugar sorghum cultivars of Lidea (No. 1, 2, 6, 8, 9, 10) formed 67.05-75.1 t/ha of green mass or more than 16-17 t/ha of dry mass. High concentration of water-soluble sugars in stems up to 13.5-16.5% was determined in phase of waxy ripeness grain of cultivars No. 4, 5, 6, 9, 10.
Conclusion. It was concluded that remontant type (stay green) is an important feature of modern corn and sorghum genotypes in production of high-energy feed (9.0-10.2 MJ/1 kg of dry matter). Remontant hybrids Voronezhsky 175 ACV, Creative, LG3285 are recommended for harvesting high-quality silage and grain fodder, prospective sorghum varieties for further testing.
