The influence of the variety and the planting period on the development and productivity of the strawberry plantation

Abstract

The present work was aimed at resolving these issues. Marmolada, Aprika and Sibilla strawberry varieties and three planting dates - the middle of June, July and August months - were taken as an object of research.

Early terms of strawberry planting promoted good tailoring and formation of 3.5 to 5.3 corms per bush on average for the studied varieties, while at planting on August 12 no more than two corms per bush were formed. Strawberry plants formed as well-developed leaf surface, 20 - 26 leaves per shrub, insignificantly different from the number of leaves formed in the second year of vegetation. Planting on August 12 resulted in a decrease in 2.3 - 2.8 times the number of leaves per shrub.

Early planting dates contributed to an increase in the number of pedicels per plant by 2.2 - 2.7 times, as well as to an increase in fruits per pedicel. This indicator reached the highest values in the variety „Marmolada”. Among the studied varieties, the highest average berry weight is characterized by the variety „Aprika” regardless of planting dates. The most productive among the studied varieties is the variety „Marmolada”, whose productivity in the first year of fruiting was the highest when planted on June 26 and amounted to 26.9 tons / ha. Late planting date of August 12 resulted in 2.2-2.7 times lower yield of plantations.

Among the studied varieties, the cultivars „Aprica” and „Sibilla” are characterized by the timeliest ripening of berries, in which the harvesting period lasts almost 20 days, and in the variety "Marmolada" it was more extended: the first two harvests were significantly lower than the third and fifth, the period stretched to 30 days.
