The objective of research is to study of fertilizer suitable for the production of oil palm study the efficacy of Tetragonula pagdeni of oil palm pollination in Langsuan district, Chumphon province. The experiment was designed as factorial in completely randomized design. Yield and yield components were collected during October 2018 - September 2019. Analysis of variance show fruit/bunch it was found that fertilizer application rates of 1 time, 1.5 times, 2 times and 2.5 times were not statistically significant. The number of beehive , 0, 4, 8 and 12, with a significant statistical significance The 12 beehive per rai gave the highest percentage of good fruit, 80.32 percent but not different from 8 beehive per rai, which gives a fruit/bunch of 78.37 percent but different from 4 beehive per rai and does not have beehive. With the average percentage of fruit/bunch being 77.50 and 76.15 percent respectively. Reaction between fertilizer application rates and number of beehive statistically significant The oil palm with fertilizer 2.5 times and 12 beehive per rai gave the highest percentage of fruit/bunch at 80.91 percent.
