Формування ценозу рослин жита озимого на ділянках гібридизації та його вплив на рівень прояву ознак продуктивності

Abstract

The results of a three-year studies on the impact of agricultural activi- ties on the formation of the parent plant makrotsenozu form hybrids of rye in the areas of hybridization. The regularities of the manifestation of productivi- ty traits of plants in different ways and norms of seeding. Thickening of crops in areas of hybridization (normal planting 3.5 - 4.0 million seeds / ha) leads  to a decrease in indicators of the main features that shape the performance. Conversely, the use of seeding rules 0.75 - 1.0 million seeds / ha performance characteristics that form the performance increase, for example, a sign of the number of productive shoots of the plant, averaged over three years, was higher by 3.8 pc. than using a seeding rate 3.0 million seeds / ha
