Response of three Cucumber cultivars to Calcium foliar feeding

Abstract

A field experiment was carried out for the year 2022- 2023 in Al- Dahra region located within 45.25 longitude and 31.39 latitude to find out the response of cucumber plants to foliar spraying with different levels of calcium. The experiment included nine treatments in which three cultivars of cucumber were used, namely Maha, Saturn, and Ramie cultivars. Codes V1, V2 and V3 were taken, respectively, and three calcium levels (0, 100, and 200 mg/ L). A factorial experiment was applied using completely randomized blocks (R.C.B.D) with three replications. The averages were compared according to the (L.S.D) test at a probability of 5%. The two cultivars V2 and V3were significantly superior in the characteristic of dry weight, which did not differ from each other, as they recorded the highest averages of 63.19 and 64.34 g. plant-1 , while the cultivar V3 excelled in the characteristic (number of fruits, fruit weight, and yield of a single plant) as it gave averages for these characteristics, it amounted to (22.19 fruit per plant, 104.87 g per plant, and 2.314 kg per plant), respectively. Calcium spray treatment 200 mg/ L was significantly superior in traits plant height and dry weight, and the two highest averages were 172.0 cm and 70.03 gm.plant-1 , while there is no significant difference with calcium 100 mg/ L in the number fruits, weight fruit, and one plant yield. The two- way interaction had a significant effect on dry weight and fruit weight, as the mean of these two characteristics was 74.93 g. plant-1 and 115.42 g. fruit-1 .
