Influence of mineral nitrogen and seeding rates on productivity of oats varieties
Studying of influence of mineral nitrogen and seeding rates on productivity of covered and naked varieties of oats is carried out. It is established, that the increase of seeding rates raises productivity of covered varieties only. Input of mineral nitrogen under cultivation and at tillering phase provided an increase of a crop of covered varieties on 0,86-1,28, of naked varieties on 0,75-1,16 t/ha in comparison with the control.
