Endophytic Root Dynamics, Yield and Quality of Aloe vera L. Plants by Application of Bio-Mineral Fertilizer Combined in Sandy Soil

This research was aimed to determine endophytic root population dynamics, yield and quality of Aloe vera L. by application of nitrogen fertilizer dosage and biofertilizers sources in sandy soil. The research was conducted in Bantul, Special Region of Yogyakarta Indonesia and arranged in a Randomized Complete Block Design with three replications. The first factor were two level of nitrogen fertilizer dosages namely 300 and 400 kg ha-1. The second factor were eight sources of biofertilizer and control (200 kg urea ha-1, without biofertilizer) treatment. The variables observed were endophytic root population, yield and quality of Aloe vera L plant. Statistic analysis of data was test by analysis of variant (ANOVA) and Duncan's Multiple Range Test at P < 0.05. The results showed that there was interaction between nitrogen fertilizer dosage and biofertilizer sources on all of observation variable. The highest endophyt population was obtained at a combination of a 300 kg urea fertilizer dosage and indigenous Rhizobacteria bamboo roots with PGPR, while hight yield and quality of Aloe vera plant obtained at a combination of a 300 kg urea fertilizer dosage and mycorrhiza source. All observational variables showed better application of a combination of urea fertilizer with biofertilizer sources than control treament. © Published under licence by IOP Publishing Ltd.
