Peningkatan Produksi Melon (Cucumis melo L.) Melalui Pemangkasan Pucuk dan Pemanfaatan Ekstrak Selasih Ungu Sebagai Atraktan Terhadap Lalat Buah (Bactrocera cucurbitae Coquilett)

Abstract

The research aimed to investigate the effect of tip pruning and basil extract as an attractant of a melon fly on the improvement of melon production, and tip pruning and the best basil extract concentration in improving melon production. It was conducted from May to August 2018 in Iloheluma Village, Tilongkabila Sub-district, Bone Bolango District, Gorontalo Province by employing Factorial Randomized Block Design with two factors. The first factor was tip pruning that comprised 3 levels which were without tip pruning, the 15th segmen of the main stem, and 20th segment of the main stem. Then, the second factor was basil comprising 3 levels which were methyl eugenol for 25%, basil extract for 40%, and basil extract for 80%. The observed parameters were fruit weight, fruit diameter, leaf area, and the melon fly number that has been trapped. The data analysis used analysis of variance method and DMRT (Duncan Multiple Range Test) at 5% level. The finding of research revealed that the tip pruning affacted fruit weight, fruit diameter, and leaf area whereas purple basil extract affected the melon fly number that has been trapped. The 15th segment of tip pruning in the main stem and methyl eugenol with 25% concentration were rocognized as the best treatment in improving the production of melon.
