Abstract

Cucumber (Cucumis sativus) is the important vegetable crop in Pakistan. Macronutrients deficiency severely affected growth and yield of cucumber. Therefore the experiment was designed to evaluate response of cucumber (Cucumis sativus) to calcium (Ca) and magnesium (Mg) levels in the year of 2014. The experiment was laid out in Randomized Complete Bock Design (RCBD) having sixteen treatment combinations, replicated three times. Foliar application of Calcium @ (0, 10, 15, 20 mM) and Magnesium @ (0, 30, 40, 50, mM) were applied to the plants. Application of calcium and magnesium significantly affected all the growth parameters. Less number of days (39) to first flowering, number of days (49) to fruit initiation, highest vine length (74.66 cm), number of branches plant-1 (6.05), number of pickings plot-1 (8), fruit length (15.02 cm), fruit diameter (4.00), number of fruits plant-1 (9.27) and yield (8.03) tons ha-1 was observed with foliar application of 10 mM calcium. Whereas less number of days  (37) to first flowering, number of days (48) to fruit initiation, maximum vine length (72.66 cm), number of branches plant-1 (5.87), number of pickings plot-1 (7.83), fruit length (15.04 cm), fruit diameter (4.43 cm) number of fruit plant-1 (9.04), and yield (10.79) tons ha-1 was observed with foliar application of 30 mM magnesium. While In case of interaction, number of days (31) to first flowering, days to fruit initiation (45), fruit length (17.27 cm), fruit diameter (5.93 cm), number  pickings-1 (9), and yield  tons ha-1(12.70) were produced by interaction between Ca x Mg at the rate of 10mM and 30 mM respectively. Hence foliar application of calcium @ 10 mM and magnesium @ 30 mM is recommended for the better growth and yield of cucumber at Peshawar.
