Respons Melon (Cucumis melo L.) terhadap Pemberian Pupuk Daun dan Beberapa Konsentrasi Boron pada Sistem Hidroponik

Abstract

Melons grown hydroponically have the problem of low fruit yield per plant. Efforts to overcome this can be done by adding foliar fertilizer and boron. Therefore, this research aims to obtain the best type of foliar fertilizer for melon yield, the best boron concentration for melon yield, and the interaction between the addition of foliar fertilizer and boron concentration on melon yield. This research used a Factorial Randomized Group Split Plot Design (RAK) with 3 replications. The first factor (main plot) is foliar fertilizer (without foliar fertilizer, Growmore 2 g.l-l, and Gandasil 2 g.l-l), while the second factor (sub plot) is boron concentration (0 mg.l-l, 0.5 mg. l-l, 0.6 mg.l-l, 0.7 mg.l-l, and 0.8 mg.l-l). Observation parameters consisted of fruit diameter (cm), fruit weight (grams), fruit flesh thickness (cm), and dissolved solids (°brix). The research results showed that Gandasil 2 g.l-l gave higher yields when compared to without foliar fertilizer and Growmore 2 g.l-l on the soluble solids parameter (fruit sweetness), boron concentration of 0.7 mg.l-l gave better results on fruit weight, fruit diameter, fruit flesh thickness and soluble solids (fruit sweetness), and there was no interaction between the type of foliar fertilizer treatment and boron concentration on all parameters observed.
