The Effect of Nano-Fertilization and Tube Size on the Qualitative Characteristics of Two Types of Strawberry (Fragaria ananassa Duch)

Abstract

This experiment was conducted in the unheated plastic house of the Horticulture and Landscaping Department of the College of Agriculture / University of Tikrit in the agricultural season 2021-2022. To study the effect of nano-fertilization at a concentration of 0, 1.5, and 3 g, and planting with different sizes of plastic tubes with a diameter of 4, 6, and 8 inches on the qualitative characteristics of two varieties of seedlings of the Fragaria ananassa Duch plant. Anthocyanins reached 18.16 mg 100gm-1, tube 6 inch was superior in terms of total acidity and reached 1.26%, while tubes 6 and 8 inch were superior in percentage of soluble solids, total sugars and percentage of dry matter in fruits. The cultivar Albion was significantly superior to the cultivar Rubygem in terms of total acidity, reaching 1.25%, while the cultivar Rubygem was superior to Albion in the percentage of total sugars, amounting to 2.23%, and the percentage of anthocyanins in the fruits, amounting to 17.51 mg 100g-1. Significant in the percentage of total solids, which amounted to 12.00%, and the percentage of total sugars, which amounted to 2.24%.
