Shoot Pruning and Potassium Application Effect on Cucumber (Cucumis Sativus L.) Seeds Production and Quality

Abstract

In order to determine the effect of shoot pruning and potassium fertilization on the production and quality of cucumber (Cucumis sativus L) seeds, a factorial experiment based on randomized complete block design with three replications was carried out in Arjasa Village, Jember regency, East Java, Indonesia, in 2018. The first factor is shoot pruning which consists of 4 levels i.e. of 6th internode, 8th internode, 10th internode, and 12th internode shoot pruning. The second factor is the potassium fertilization in three levels i.e. 100 kg ha-1, 200 kg ha-1, 300 kg ha-1. Production and quality of seed cucumber was assessed based on fruit weight, number of grain per fruit, percentage of filled grain, 1000 grains weight, seed viability and vigor. The results indicated that was significant different on interactions of two factors effect on physiological ripe fruit weight, grain number and percentage of filled grain. The 8th internode pruning gives best result on physiological ripe fruit weight, seed viability and vigor. Application of potassium at a dose of 300 kgha-1 gives the best results on fruit weight, 1000 grain weight and percentage of filled grain.
