ABOUT THE REASONS OF SOME BIOLOGICAL FEATURES IN ANNUAL PLANTS IN CASE OF SUMMER SOWING AND ITS PRACTICAL USE
N.I. Buyankin
During more than 30 years in various regions (North Kazakhstan, Kaliningradskaya and Arkhangel’skaya oblast’) the author investigated the features of morphology, accumulation and quality of green mass in summer sowing of oats, rape and alfalfa. The observed changes are discussed in connec-tion with spectral distribution of sun radiation in temperate latitudes during spring-summer and summer-autumn periods, day length and fixed evolutionary photoperiodic plant reaction on typical ecological conditions of vegetation period.
Key words: fallow ground, summer sowing, ecological principle.
