Dry matter production and nutrient uptake by PS1 and DxP planting materials on typic endoaquepts soil in Sabah
AHMAD AFANDI Murdi , AHMAD TARMIZI Mohammed , MOHD HANIFF Harun , ZULKIFLI Hashim , NOH Ahmad , HAMDAN Abu Bakar , KHAIRUMAN HashimAn attempt was made to quantify the dry matter production and nutrient uptake by PS1 oil palm planting materials during the immature stage. The results show that at 43 months after planting, the total fresh and dry weights of PS1 were 22.50% and 6% higher respectively as compared to the commercial DxP, but the differences were not significant.
The concentrations of nitrogen and phosphorus in various palm components of PS1 and DxP were not significantly different. However, the concentrations of potassium and calcium in the‘cabbage’ of PS1 were 77% and 113% higher respectively than those of DxP. The concentration of magnesium in the spears of DxP was 108% higher than that of PS1. The ranking order of nutrient content (kg palm-1) in the whole palm components of both types of planting materials was K >, N >, Ca >, Mg >, P.
The total uptake of each nutrient for both materials was not significantly different. PS1 planting materials are comparable to the commercial DxP in terms of dry matter production and nutrient uptake.
