Abstract
INTRODUCTION Arumanis Mango is one of the national superior mango cultivars that has potential to meet domestic and export market consumption. However it is still constrained by the low yield and fruit quality, which is caused by the application of traditional cultivation techniques by farmers. To solve this problem innovative cultivation technology is needed. The purpose was to study the technology of mango fruit production at off-season used growth regulators namely paklobutrazol, ethepon and paclobutrazol with organic fertilizer application on the Arumanis mango plant. The study was conducted in the mango farm owned by PT.Friga in Jarangan Village, Rejoso District, Pasuruan Regency, East Java Province. The research was conducted from March to October. Mango plant material used was 25 years old. The research was carried out with three treatment namely: I. Paklobutrazol dosage was control (0 ml l-1 / tree, 5 ml l-1 / tree, 10 ml l-1 / tree and 15 ml l-1 / tree). II. Ethepon dosages (0 ppm / tree, 400 ppm / tree, 600 ppm / tree and 800 ppm / tree) that applied 1 month after paklobutrazol addition. III Paklobutrazol and organic fertilizer application in combination as follows: 1) Control, 2) Paklobutrazol 5ml + fertilizer 10kg, 3) Paklobutrazol 10ml + 15kg fertilizer and 4) 15ml Paklobutrazol + 20kg fertilizer. Randomized Complete Block Design (RCBD) with 5 replications was used for this research. RESULTS AND DISCUSSION The results showed that off-season technology treatment with paklobutrazol, ethepon and packlobutrazol + organic fertilizer were significant (Table 1). The results indicated that (1) Paklobutrazol application accelerated the flowering age, shortens the panicle length, and increased fruit yield of tree. Moreover there wasn-t difference among doses of Paklobutrazol, (2) Giving ethepon accelerated the flowering period, enhanced the panicles number and yields of trees compared to controls. The treatment of ethephones 600 ppm produced the highest fruit weight, 182.60 kg, respectively (3 ) The Paklobutrazol and organic fertilizer application indicated that the panicles number and the fruit weight yield of tree is higher than the control, but there wasn-t difference between application of paklobutrazol with the addition of organic fertilizer. The results were consistent with the study of Husen et al. (2012) that application of paklobutrazol 5 ml / l on a 5-year-old hybrid mango could accelerate the flowering time and increased the number of fruits. Moreover, Tandel and Patel (2011) reported that application of paklobutrazol increased fruit number and total production per tree for Alphonso cultivars. Paklobutrazol doses also significantly accelerated flowering and yield in Lechi Ankit et al. (2017).
