Формирование урожайности семян озимого рапса в зависимости от норм высева в условиях северо-восточной части Беларуси

Abstract

The results of research for 2009–2011 to study. We influence of seeding rate on plant winter hardiness seed and yields of winter rape hybrid Elvis and variety Leader are given. Hybrid has the optimum plant parameters in autumnу vegetation period at the seeding rate 0,5–0,75 millions of seeds per hectare and the variety has the optimum plant parameters 1,0–1,25 millions of seeds per hectare. The greatest winter hardiness and the highest seed yields of Elvis – 41,0–41,1 cwt/ha are received at the seeding rate 0,5–0,75 millions of seeds per hectare. Variety Leader has the maximum productivity 31,1–32,1 cwt/ha at the seeding rate 1,0–1,25 millions of seeds per hectare
