Garden strawberry: the effect of micronutrients foliage spraying on winter hardiness in the Krasnoyarsk forest-steppe

Abstract

The work highlights the results of studies on the application of foliar treatments with micronutrient solutions N-1.6% + 8 minor-nutrient elements (Fe-0.4%, Cu-0.12%, B-0.028%, Mn-0.36%, Zn-0, 09%, Mg-0.05%, Mo-0.08%, Co-0.016%); Cu 1% + 7 trace elements (Mn-0.018%, Fe-0.02%, Mo-0.004%, Co-0.00018%, B-0.0014%, Zn-0.0045%, Mg-0.0025 %); Fe 2% + 7 minor-nutrient elements (Mn-0.018%, Cu-0.006%, Co-0.0008%, B-0.0014%, Mo-0.004%, Zn-0.0045%, Mg-0.0025%) in plantings of strawberry varieties Elista, Pervoklassnitsa, Zephyr, Solnechnaya Polyanka. Agrochemical parameters of the soil before planting bushes of garden strawberries showed its high fertility by a set of indicators. At the same time, there was a deficiency of minor-nutrient elements: low content - Cd, Cu, Zn, Co, Cr. The availability of manganese and lead is average. The foliage spraying of plants with micronutrient solutions did not provide a statistically significant confirmation of the effect on the winter hardiness of plants; these indicators depend solely on the varietal characteristics of the sample.
