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

Cemaran getah kuning merupakan masalah utama yang menyebabkan rendahnya mutu buah manggis. Keseimbangan ketersediaan hara kalsium (Ca) dan boron (B) dalam tanah diduga berperan penting dalam pengendalian cemaran getah kuning pada buah manggis. Tujuan penelitian ini untuk mendapatkan kombinasi dosis kalsium dan boron yang tepat untuk mencegah cemaran getah kuning pada buah manggis. Penelitian dilaksanakan di Purwakarta, Jawa Barat dari Bulan Nopember 2012 sampai Juni 2013. Rancangan percobaan yang digunakan ialah acak kelompok faktorial dengan tiga ulangan. Perlakuan terdiri atas dua faktor yaitu dosis Ca (0,0; 2,5; 5,0; dan 7,5 kg/pohon) dan dosis B (0,00; 0,77; 1,55; dan 2,32 g/pohon). Hasil penelitian menunjukkan bahwa pemberian Ca dan B dapat menurunkan persentase dan skor cemaran getah kuning pada aril dan kulit buah. Terjadi interaksi pemberian Ca dan B terhadap skor dan persentase cemaran getah kuning pada aril. Persentase cemaran getah kuning pada aril terendah (2,67%) diperoleh pada kombinasi dosis 5,0 kg Ca/pohon+1,55g B/pohon. Hasil penelitian ini dapat dijadikan pedoman kombinasi dosis Ca dan B untuk menanggulangi cemaran getah kuning pada buah manggis.
