The availability of slow-moving elements within the plant is very important for the growth and productivity of crops, the most important of which are calcium and boron, and the deficiency of any of them leads to a significant imbalance in growth and productivity. This experiment was conducted inside a greenhouse at the National Organic Agriculture Center, Unaiza, Qassim, Ministry of Environment Water and Agriculture, Saudi Arabia to investigations made on the effects of foliar applications levels of calcium (Ca) and boron (B) on yield and quality of strawberries (Fragaria X ananassa Duch.). Factorial experiment was used in a randomized complete block design (RCBD) with four levels of calcium (Ca1=100, Ca2 = 200, Ca3= 400 mg/l), and four levels of boron (B1= 5, B2= 10, B3= 20 mg/l), as well as control treatment (C=0), each treatment was replicated three times. Different treatments with different combinations of both elements were studied. Addition of B and Ca influence vegetative growth parameters, yield attributes and fruit quality parameters significantly compare to the control such as the percentages of Glucose%, Fructose%, vitamin C and Sucrose%. Therefore, results indicated that sprays of mixture contained calcium and boron at different levels of Ca2B1, Ca1B1 and Ca3B1 increased fruit diameter, fruit length, weight /plant, and total weight (g), while with Ca3B1 and Ca3B2 were showed high increment of sugar percentages. According to results authors recommended foliar application of combination of calcium and boron as follow Ca2B1, Ca3B1 and Ca3B2 to improve yield attributes and fruit quality parameters.
