Increasing Yield of Oil Palm with Appropriate Management According to Area in Community in Nakhon Phanom

Abstract

This research aim to develop oil palm production of farmers in Nakon Phanom for increasing yield. The trial of oil palm technological production conducted in oil palm orchard of farmers at the age 6-9 years iin Tha-U-Then and Phonsawan District from 2019 - 2021. The results of soil and leaf analysis showed the pH were in the range of moderate to highly appropriate level, organic matter was in the range of low to highly appropriate level. The nutrient, phosphorus, potassium and magnesium were lower than appropriate level both in soil and leaves. The DOA method, fertilizer application based on nutrient analysis of oil palm leaf and watering in dry season were demonstrated to compare with farmers’ practice. We found that in the 1^st 2^nd and 3^rd year of the research oil palm of DOA method, both fertilizer and water application gave the yield average at 2.13 2.73 and 3.12 ton/rai, respectively, more than the yield of farmers’ practice at 14.5 12.8 and 9.51%. The DOA method, which only fertilizer application showed the yield average at 1.62 2.30 and 2.32 ton/rai, respectively, more than the yield of farmers’ practice at 13.1 22.7 and 18.8%, respectively.  The result showed the fertilizer application and both of water and fertilizer application were used to increase oil palm productivity in Nakhon Phanom Plantation.
