Synergy of application fertilizer leaves and organic growth regulatory for growth and production potential of eggplant plants (Solanum melongena L.)

Abstract

Eggplants (Solanum melongena L) is a vegetable that people like. Provision of nutrients through leaves and organic hormones which are sustainable materials are expected to increase the productivity potential of eggplant plants. This is caused by the synergy of the application of leaf fertilizer and plant growth hormone. The study was conducted at the Krian District Counselling Centre using a polybag with Factorial Complete Randomized Design repeated three times. Factor I: Leaf Fertility Concentration with 4 treatment levels (G0 = 0g/l water; G1 = 1 g/l water; G2 = 2 g/l water; and G3 = 3 g/l water). Factor II: ZPT concentrations with 4 levels of treatment (Z0 = 0 cc/l water; Z1 = 1 cc/l water; G2 = 2 cc/l water; and G3 = 3 cc/l water). There is a synergy between the application of leaf fertilizer and ZPT on fruit quality with the best application in leaf fertilizer concentrations of 1cc/l and ZPT 2cc/l, where the potential diameter of the fruit increases by 15% and the length of the fruit increases by 28%. The highest potential for vegetative growth is in the application of 1g/l leaf fertilizer where the potential for production increases with 1g/l fertilizer application and 2cc/l hormone administration. The application of leaf fertilizer and hormones gives an increase in yield compared to control where the application of leaf fertilizer increases the potential for growth by 16% and increases the fruit production potential by 66%. In addition, the application of the 2 cc/l hormone can increase growth potential by 6% and increase fruit production potential by 69%.
