Title : The effect of spraying different dosages of calcium nitrate and calcium chloride on fruits of tomato cultivars grown in perlite in a cold greenhouse on blossom end rot and fruit cracking
Abstract:
In this experiment, The Effect of Spraying Different Dosages of Calcium Nitrate and Calcium Chloride 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, beefsteak 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 block design. As a result, According to the main effect of the variety, the Moneymaker variety gave more fruit in terms of fruit number. But Brandywine gave more yield (kg/plant) than Moneymaker. Fruit weight and fruit diameter were higher in Brandywine than in 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.
