“…The FUE of rice can be affected by water management. Our results indicate that N is not a requirement of sago during the early stages of growth and sago palms without N application showed superior growth in most parameters, despite an increase in N uptake for palms supplied with N. Matsumoto et al (1998) suggested that sago palms have a lower demand for several nutrients than oil palms, and this is consistent with the low sensitivity of sago palms to N fertilizer application in our study and in previous studies. The low N uptake efficiency of sago should be considered when planning N fertilization, so that losses of large amounts of unutilized N can be avoided.…”

Previous trials have revealed variable responses of sago palm (Metroxylon sagu Rottb.) to fertilizer application, particularly nitrogen (N). In the present study, we quantified the fertilizer use efficiency (FUE) of sago palm for the first time using 15N‐labeled fertilizer in pot and field experiments. The pot experiment was conducted in Japan using a 2:1 mixture of sand to Philippine soil. The field experiment was conducted in Leyte in the Philippines. Both experiments consisted of three replicates in each of three treatments: control, 15N urea at 50 kg N ha−1 and 15N urea at 100 kg N ha−1. The N uptake of sago palm increased significantly, but inconsistently with increasing N application. The few instances of a significant increase in N uptake did not translate into significant improvements in growth parameters, except for the number of leaflets in the pot experiment. The FUE values for sago seedlings (< 6 months) in the pot experiment treated with 50 and 100 kg N ha−1 were 10.5 and 13.2%, respectively, whereas for the 2‐year‐old sago palms in the field, the corresponding FUE values were 14.8 and 12.0%. The FUE values were similar at the two levels of N application in both experiments. Sago growth parameters appeared to be insensitive to N application, suggesting that the form of N and the timing of N fertilization are important factors for sago palms. Therefore, the use of N fertilizer in sago production can only be justified after determining and fully understanding the response of sago palm to N application.

“…In addition, higher P levels were applied to older plants (Table 2), which resulted in higher P concentrations in the soil (Table 1) and, consequently, greater absorption by older plants (Figures 2a and 2b). Matsumoto et al (2008) analyzed oil palm in terms of age and observed higher P concentrations in leaflets (4.34 g kg -1 ) and petioles (4.92 kg g -1 ) in the third year. Bachy (1965) also found an increase in the P concentration in leaflets (leaf 17) according to oil palm age, corroborating our results.…”

Amazon soils have a low phosphorus (P) availability and few studies have investigated nutrition of palm oil plantations. This study assessed the effects of P nutrition on oil palm organs according to plant age. The experiment was carried out under field conditions, at the enterprise Agropalma S/A, in the municipality of Tailândia, Pará State, Brazil. The experimental design used was completely randomized with four replications and comprised seven treatments: plants age (2, 3, 4, 5, 6, 7, and 8 years of planting). We evaluated P concentration, accumulation, and exportation in plant components (leaflets, petioles, stipe, rachis, palm heart, arrows, male inflorescences, peduncles, spikelets, and fruits). Palm heart (10.9 g kg-1) and male inflorescence (3.8 g kg-1) showed the highest P concentrations in the vegetative and reproductive organs, respectively. On the other hand, the largest P accumulations were observed in the stipe (159 g plant-1) and fruits (59 g plant-1), increasing from the 3rd year of age of the plants. Bunches exported the largest P amounts (81 g plant-1), especially in older plants. The oil palm immobilizes (24 kg ha-1) and recycles (23 kg ha-1) a large amount of P, more than it exports (12 kg ha-1) P.

In the state of Sarawak, Malaysia's vast peatland cultivated with sago palm (Metroxylon sagu), a considerable amount of cases involving stunted, nondeveloped trunk of sago palms was observed. Molecular-level understanding of the mechanism or pathway involved in the trunking (T) process leading to storage starch accumulation in the trunk of the sago palm is yet to be fully understood. A Polymerase Chain Reaction-based differential display analysis using Annealing Control Primer based GeneFishing technique on leaf samples of normal T compared to the nontrunking (NT) palm showed distinct differentially expressed transcripts pattern with differences in intensity between 35% and 123%. The translated sequence identified functions that are grouped under energy metabolism, nutrient regulation, biosynthetic reactions, defense mechanism, and stress tolerance. Transcripts from T showed higher expression of redox-regulating functions, while NT samples had proteins actively involved in the respiratory chain and chloroplast regulation. In nutrient regulation, the T sample showed higher transcript levels of nitrogen utilization and regulation of phosphate and cobalt, whereas NT showed activities of nitrogen uptake and regulation of calcium, magnesium, and zinc. This study identified different levels of transcripts in two physiologically different sago palms, and the formation and the development of the trunk are induced by these enzymes.
