Formation of alfalfa leafiness by the phases of growth and development

Abstract

The results of two-year studies (2017—2018) on the effect of the seeding rate and row spacing on the leafiness of alfalfa plants of different geographical origin carried out on the gray forest soils of the right-bank Forest-Steppe are presented. It is established that the variety of the southern breeding Angelica prevailed over the local variety Rosan by its leafiness by 0.5—1.6 % regardless of the phase of growth and development. The highest leafiness indices were obtained when the seeding rate was 8.0 million/ha, which amounted to 50.9—51.8 %. The row spacing provided the growth of the leaf mass by 0.2 %.
