Abstract:
The field experiment was conducted on an Ultic Haplustalf in Kanchanaburi Research Station, Muang district, Kanchanaburi province, west of Thailand for a period of one year (July 2009 to June 2010). A Randomized Complete Block Design (RCBD) was employed with eight treatments and four replications. The treatments consisted of no fertilizer as a control (F1) and others with different fertilizer managements (F2-F8). The study aimed at investigating the response of Jatropha curcas L. (Euphorbiaceae) to applied fertilizers. Jatropha curcus (KUBP 78-9 Var.) was planted using direct seed at a spacing of 2x2 m. Drip irrigation was used to apply water at the rate of 2 L tree-1 in every 2 days for whole period of the study. Jatropha curcus began flowering in October 2009, three months after planting and capsule cluster was detected a month after. Seed yield measured at 15% moisture was highest in the first month of harvest in February 2010 and decreased until June 2010. The application of 25 kg N+75 kg P2O5+75 kg K2O ha-1 together with compost at the rate of 6.25 t ha-1 statistically gave the highest oil yield of 456.9 kg ha-1. This amount was highly significantly greater than those obtained from other treatments including the control. There was no influence of applied fertilizer on all plant nutrient concentrations in J. curcus leaf collected at 2 and 6 months of age. A positive correlation between Mn concentration in 2 months old leaf and seed yield was found. The concentration of Mg and Fe in 2 months old leaf negatively correlated with seed yield and Fe and Zn concentrations in 6-month old leaf with oil yield.
