Abstract

Mangosteen (Garcinia mangostana Linn.) dubbed as “finest fruit of the world”, has potential for both domestic market and export. However, this potential is threatened by low fruit quality caused by production of yellow latex and fruit scarring. The research objective was to obtain technology to reduce yellow latex and control Scirtothrips dorsalis, a pest that causes scarring on mangosteen. A randomized block design with four treatments and 14 replications was used in this research. Significant differences among the treatments were calculated using the Honestly Significant Difference (HSD) test. The results showed that treatment of drip irrigation system in combination with removing weeds under the canopy (A) or removing weeds followed by minimum tillage under the canopy (B) or removing weeds then covering with rice hay mulch under the canopy (C), where N, P, K, Ca, Mg fertilizer and yellow fluorescent sticky trap were applied could reduce scarring intensity and percentage of yellow latex on the fruit peel. However, the treatments did not significantly impact fruit diameter or percentage of yellow latex inside the fruit. Nevertheless, treatment C improved mangosteen quality by as much as 67.79% fulfilling export standard requirements.Keywords: Mangosteen, quality improvement, drip irrigation, yellow fluorescent sticky trap

Abstract

Salicylic acid is one of the elicitor substances that can be used to reduce the level of damage of plants, both by pathogen and herbivore. The application of salicylic acid also affects plant growth and productivity. The impact of the salicylic acid application on a plant varies, such as depending on concentration, mode of application, and plant species. This research aimed to know the effect of different salicylic acid concentrations on mealybug development and papaya growth. The results showed that salicylic acid at concentrations of 100 mg/l slowed mealybug development and suppressed the amount of fecundity. Still, it caused a plant to grow smaller relatively. The application of salicylic acid at a concentration of 50 mg/l was the best treatment because it provided the best growth of papaya plants and suppressed the fecundity of mealybug.
