The effect of spraying different dosages of calcium nitrate and calcium cloride on fruits of tomato cultivars grown in perlite in a cold greenhouse on blossom end rot and fruit craking

In this expriment, The Effect of Spraying Different Dosages of Calcium Nitrate and Calcium Cloride on Fruits of Tomato Cultivars Grown in Perlite in a Cold Greenhouse on Blossom End Rot and Fruit Craking was investigated. In the experiment, 3 calcium doses (W/V %0 Ca, % 0.0475 Ca and %0.1425 Ca), 2 cultivars (Brandywine: Cordon cultivar,beefstake fruit tomato, and Moneymaker: Medium sized fruit, cordon cultivar) and 2 Calcium sources (Calcium nitrate (Ca(NO3)2) ) and Calcium chloride (CaCl2 )) were used. There were 12 combinations as factorial, and for each cultivar, the plot of land was included in the experiment as a control. Accordingly, 14 subjects were arranged in two blocks according to the randomized blocks design. As a result, According to the main effect of the variety, Moneymaker variety gave more fruit in terms of fruit number. But Brandywine gave more yield (kg/plant) than Moneymaker.Fruit weight and fruit diameter was higher in Brandywine than Moneymaker. According to the main effects of calcium dose and calcium source, %0.0475Ca and % 0.1425 Ca CaCl2 gave less BER and cracked fruits.
