STUDY OF FERTILIZER (ORGANIC and INORGANIC) FORMULATION TO IMPROVE GUBAL AGARWOOD FORMATION IN PLANT KETIMUNAN (GYRINOPS VERSTEEGII).

STUDY OF FERTILIZER (ORGANIC DAN INORGANIC) FORMULATION TO IMPROVE GUBAL AGARWOOD FORMATION IN PLANT KETIMUNAN (GYRINOPS VERSTEEGII). I Made Mega and A.A. Nyoman Supadma Program study of Agroecotechnology, Agriculture Faculty, Udayana University Denpasar Email: mega_made@yahoo.com ABSTRACT Study of Fertilizer (Organic + Inorganic) formulation to Improve Formation of Gubal Agarwood in Plant Ketimunan (Gyrinops versteegii), aims to find a formula fertilization technology packages (organic + inorganic) is appropriate and balanced to enhance the growth and formation of fragrant gubal aloes quicker and more. In a study this first year, the research using field trials in village Marga Tabanan, with a randomized block design, There are seven packages formulations of organic fertilizers inorganic try is: A (control), B (50 g urea + 50 kg SP-36 + 50 KCl kg + 10 kg compost) + 50 g Dolomite), C (100 g urea + 100 g SP-36 +100 g KCl) + (7.5 kg compost) + (75 g Dolomite), D (150 g urea +150 g SP-36 + 150 g KCl) + 5 kg compost) + 75 g Dolomite), E (200 g urea + 200 g SP-36 + 200 g KCl) + 2.5 kg of compost + 100 g Dolomite), F ( 200 g urea + 200 g SP-36 + 200 g KCl) + 2.5 kg of compost + 100 g Dolomite), G (200 g urea + 100 g SP-36 + 100 g KCl) + 7.5 kg of compost) + 75 g Dolomite) per tree, and repeated three times so that the number of plants was 21 trees. After the plants were inoculated with the fungus Fusarium solani and Rhisopus sp inoculant. The agarwood plant immediately fertilized according to treatment is attempted. The observed parameters: plant height, diameter of crops stem, weight gubal, resin content and data soil chemical properties. Data were analyzed statistically in accordance with the design that is used to determine the significance of the effect of treatment, if the treatment effect was significantly different, then the test continued Duncans 5%. Results of statistical analysis of the parameters observed showed significantly different influence on the increase of plant height, weight gubal agarwood, and the yield of resin that is formed, but not significantly different effect on the diameter of the stem. The highest gubal weight parameters obtained in treatment C amounted to 14.39 g. Average yield of the ultimate resin obtained in the treatment of B of 3.91%, and decreased non significant in treatment C with a resin yield of 3.85%. Formulation of fertilizer (organic + inorganic) are either are treatment C (100 g urea + 100 g SP-36 +100 g KCl) + (7.5 kg compost) + (75 g Dolomite) per tree, which produces the largest diameter crops stem, weight gubal agarwood is higher, and a high yield of resin.
