Abstract
Proper nutrient at the right time increases fruit quality, and yield of strawberry plants. An experiment was conducted with the aim of reducing vegetative growth and increasing yield and fruit quality of Selva strawberry cultivar using paclobutrazol (0, 100 mg lˉ¹), boric acid (0, 150, 300 mg lˉ¹) and zinc sulfate (0, 100, 200 mg lˉ¹). Rooted runners of strawberry grown in the greenhouse under hydroponic condition were used. The criteria measured were leaf number, leaf area, length and diameter of petiole, fresh and dry shoot root ratio, yield, total soluble solid, acidity and vitamin C. Results indicated that vegetative growth was reduced with PP333. Zinc (ZnSO4) had positive effect on criteria measured. However, combined PP333×B decreased total soluble solid in fruits. Highest vitamin C was obtained at concentration of (0-300 mg lˉ¹ PP333- B). Foliar application of ZnSO4 prior to flowering was recommend to increase fruit quality and yield of strawberry
