The Application of Nitrogen Fertilization and Foliar Spraying with Calcium and Boron Affects Growth Aspects, Chemical Composition, Productivity and Fruit Quality of Strawberry Plants

Strawberries are rich in antioxidants and plant components to enhance cardiac health regulate blood sugar. This experiment investigates the effects of N fertilization foliar spraying with calcium (Ca) boron (B) on growth, chemical composition foliage, fruit yield, quality strawberry plants (Fragaria × ananassa Duch. cv. Fortuna). includes 12 treatments from combination between four fertilizers (combinations mineral organic fertilizers) three Ca+B at 2 4 mL/L addition control treatment (spraying tap water). Results show that where 50% recommended dose (50% RDN) was applied fertilizer + 100% most effective one since it induced highest values height, number crowns per plant, leaves fresh dry weight especially when combined application tested rate (4 mL/L). The N, P, K, Ca, B, total carbohydrate contents were also scored for RDN both growing seasons. In addition, yield hectare, exportable yield/ha, firmness, TSS, Vitamin C, sugars, anthocyanin, as well lowest acidity recorded value length, diameter, by fertilizing (100% conclusion, could be suggested half increases growth improve parameters plants.
