STUDY OF THE EFFECT OF ADDING CALCIUM AND NPK FERTILIZER ON STRAWBERRY SEEDLINGS FRAGARIA X ANANASSA DUCH

The study was conducted in the Department of Horticulture, University of Mosul in 2019/2020. The experiment was conducted with two factors,the first factor was NPK fertilizer (20:20:20) with three levels (100, 150 and 200 mg.L-1), while the second factor was Calcium nitrate with three levels 1%,1.5% and 2%. Calcium nitrate increased the growth parameters significantly in leaves number, number of crown, number of fruit, fruit weight, fruit length, number of runners, total yield, number of distorted fruits, the area of one seedling, number of flower, the number of fruit set, leaf area, and chlorophyll content. The NPK recorded the highest rate in the studied traits leaves number, number of crown, Number of fruit, fruit weight and fruit length number of runners total yield, number of flowers, leaf area, leaf Chlorophyll content, the area of one seedling, and number of distorted fruits. The data were analyzed through the statistical analysis program (SAS) based on Duncan's polynomial test.
