Abstract
This study aimed to evaluate the soil and leaves nutrient status on the growth of cultivated tabatbarito (Ficusdeltoidea Jack) in various level ages. The field experiment was conducted during December 2015 to November 2016 at Makroman Village, Samarinda-East Kalimantan. On 6, 9, and 12 months old after planting (MAP) the data was collected to evaluate the plant height, leaf number, branch number, biomass, soil and leaves nutrient concentrations. The results showed that the average pH of soil was 3.92±0.06, categorized as a very acid. The concentration of soil nutrients were: nitrogen (1.13±0.31 %), phosphorus (0.01±0.01 ppm), potassium (297.60±50.11 ppm), calcium (2.97±1.79 cmol(+)Kg-1), and magnesium (3.69±2.30 cmol(+)Kg-1). The leaf nutrient concentration was 1.74±1.42 % (N), 0.25±0.19 % (P), 1.86±0.15 % (Ca), 1.88±0.29 % (Mg). The soil nutrients concentration (N, P, Mg) and the leaf nutrient (N, P, K, Ca, Mg) has a correlates with plant height increment, branch number increment, and biomass increment. The results indicated that the N, P, K, Ca, Mg played an important role in the growth of F. deltoidea and this nutrient should be considered well when this plant will be cultivated as a source of the medicinal plant on a large scale.
