Effect of the Combination of Some Fertilizers on Chlorophyll Content of Gemor ( Nothaphoebe coriacea )
Аннотация
Our study aimed to determine the influence of various fertilizer combinations on chlorophyll content of gemor (Nothaphoebe coriacea). The study was conducted in the laboratory and nursery, Banjarbaru forestry research institute, South Kalimantan, Indonesia in January-March 2014. The study used a completely randomised design with one factorial as fertilizer treatment. Fertilization treatments included s no fertilizer (control) (T1); Urea (T2), Urea + SP-36 (T3); Urea + SP-36 + KCL (T4); and Urea + SP-36 + KCl + Dolomite (T5). Chlorophyll content was measured refering to spectometry method. Data were analyzed using Duncan Multiple Range Test (DMRT). The results showed that only T3 groups of treatment had significant effect on chlorophyll a, chlorophyll b, and total chlorophyll of gemor. The conclusion of this experiment is that using combination of urea + SP-36 together have improved the chlorophyll a, b, and total chlorophyll content of gemor. Therefore, on-farm trials must be achieved to confirm results before authorising their popularisation in peasants via the multilocation and multiannual trials.
