Abstract
Relevance. Currently, it is relevant to study the productive potential of corn hybrids of different maturation periods. In the agro-climatic conditions of the Bryansk region the yield of green mass and grain of corn hybrids was assessed on the gray forest medium loamy soil. The object of the research was the earlymaturing hybrids Mashuk 168, Mashuk 170 MV, MA 1919, MA 171, Mashuk 175 MV, Voronezh 160 SV, Mashuk 220 MV, Mashuk 250 SV, Mashuk 300.
Methods. The field research was carried out according to the Methodology of the state variety testing of agricultural crops, statistical processing according to B.A. Dospekhov.
The purpose of the research was to identify the most productive domestic corn hybrids in terms of green mass and grain.
Results. In the field experiments it was found that in the conditions of the south-west of the Central region of Russia on the gray forest medium loamy soil the corn hybrids Baikal, MA 198, Mashuk 185 MV, Mashuk 250 SV had the highest yield of green mass — from 54.42 to 64.76 t/ha, while Mashuk 171 and Newton formed 51.51-53.44 t/ha. Having a low leafiness of the stems, the hybrids Voronezh 160 SV, Mashuk 175 MV, Mashuk 168, MA 1919, Pyatigorsky 146 MV, MA 171 had a yield of green mass from 25.18 to 37.19 t/ha. The hybrids Mashuk 171, Mashuk 250 SV, Baikal and Mashuk 170 MV showed the highest biological grain yield of 9.05–10.98 t/ha, while Mashuk 300, Mashuk 220 MV, MA 198 formed 8.43–8.99 t/ha, respectively. The yield of the remaining hybrids was at the level of 5.57–6.94 t/ha.
