Influence fractions of the planting materialon the yeild of garlic winter [PDF]

open access: diamondBulletin of Kharkiv National Agrarian University named after V.V. Dokychaiev. The series “Crop production, selection and seed production, fruit and vegetable growing”, 2019
The influence of different fractions of planting material (large, medium and small) and the density of standing plants on the yield capacity of garlic bulbs has been studied. It has been found out that the highest average yield capacity is formed from the large fractions of cloves at a lower density.
