Response of growth and production of melon (Cucumis melo L. var. inodorous) on different concentrations of AB mix fertilizer and gibberellin in tefa smart green house polije

Abstract

Abstract Melon is an important horticultural commodity in Indonesia because it has high commercial value and broad market target. TEFA SGH Polije has been known as an agribusiness producer of high-quality melons in Jember and it needs to be developed to increase productivity and economic profit. This study aimed to determine the effect of different concentrations of AB Mix and Gibberellins and their interactions on increasing the growth and production of hydroponically cultivated melons. This research was conducted from June to August 2022 at TEFA SGH Polije at 90 msl. This research used Factorial Completely Randomized Design. The first factor was the AB mix concentrations, i.e., 1,400; 1,600; 1,800 and 2,000 ppm. The second factor was the gibberellin concentrations, i.e., 0; 30; 60; 90; 120 and 150 ppm. Each treatment combinations were repeated three times, so there were 72 experimental units. Each experimental unit used 3 plant samples. Observation variables were stem diameter, fruit weight, fruit diameter, fruit flesh thickness, total soluble solids and leaf chlorophyll content. Data were analyzed using analysis of variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT). The interaction between AB Mix and gibberellin had significant effects on stem diameter and fruit flesh thickness.
