“…Besides a citric acid, [12] mentioned that salicylic acid also plays a role in stimulating antioxidants so that lipid peroxidase was slowed down. This was in agreement with our work on oil palm seedlings exposed to Al stress under nutrient culture [24]. 3 revealed a decrease in the number of rejected bunches due to the applications of exogenous compounds in all treatments compared to controls, the decrease of which was followed by an increase in the average bunches weight (Table 3).…”

“…Based on these results, it is clearly seen that salicylic acid and citric acid exert a significant positive influence on the increase in the rate of photosynthesis. According to [22][23][24] the application of citric acid was able to increase the rate of photosynthesis on Al-stressed plants. Salicylic acid plays an important role in maintaining the integrity and function of photosystems in photosynthesis, which promoted plant tolerance to Al stress [25].…”

The low productivity of oil palm grown on suboptimal land Ultisols with high Al saturation requires efforts to improve cultivation techniques in order to increase plant tolerance to Al stress and to improve fruit production. This study aimed to determine the effect of various exogenous compounds on physiological changes and fruit production of oil palm (Elaeis guineensis Jacq.) grown on Ultisols with high Al saturation. This study consisted of 2 treatments, namely: (1) a combination of various exogenous compounds, and (2) application methods. The experiment was arranged in RCBD split plots with 3 replications. Treatment of exogenous compounds was (1) control (untreated); (2) CaCl2 50 ppm; (3) CaCl2 50 ppm + Salicylic acid 50 ppm; (4) CaCl2 50 ppm + Salicylic acid 50 ppm + citric acid 50 ppm; (5) CaCl2 50 ppm + Salicylic acid 50 ppm + citric acid 50 ppm + boron 50 ppm; and (6) CaCl2 50 ppm + Salicylic acid 50 ppm + citric acid 50 ppm + boron 50 ppm + Cu 50 ppm. The application method used was (1) basal drench and (2) foliar spray. Application of exogenous compounds was carried out every 3 months. The results revealed that application of exogenous compounds has enabled plants to increase the tolerance to Al stress, as evidenced by an increase in the number of normal bunches and bunch weight, the increase of which was due to the decrease in the number of rejected bunches, especially in the CaCl2 + salicylic acid treatment, which was selected as the most effective treatment. Increased fruit production in this treatment was associated with improvements in physiological processes; decreased MDA and increased photosynthetic rate and activity of APX and CAT enzymes resulted in improvement fruit production. These positive changes in physiological processes after treatment suggested that the addition of those exogenous compounds has induced signalling processes involved in ROS scavenging, that promoted the tolerance to Al stress. Basal drench application method was more effective than foliar spray, this was related to the increase in soil pH and P available due to the application of exogenous compounds through basal drench method.

“…Kpomblekou and Tabatabai [60] reported that the release of P from the PRs to acids was afected by the chemical structure, type, and position of the functional groups of the ligands and the concentration of the acids. Citric acid up to 100 ppm concentration increases the tolerance of oil palm seedlings to the stress of Al, becoming complex compounds that are difcult to dissolve [61]. In this research, 100−200 ppm was a concentration of OA that could provide lower soil exchangeable Al compared with other OA concentrations.…”

Problems encountered in the management of upland acid soils, besides soil pH, are also low in phosphorus (P) content and less available to plants. The addition of organic acids (OAs) to the direct application of phosphate rock (PR) has not been widely studied yet and is expected to improve upland acid soil properties. The research aims to determine the effect of adding OAs on the direct application of PR to improve upland acid soil and increase maize yield. It was a greenhouse experiment using a randomized complete design in a factorial arrangement with three replications. The treatments consisted of four types of OA (citric, humic, succinic, and oxalic acid) and five OA concentration levels (0, 25, 50, 100, and 200 ppm). The hybrid maize (Zea mays L) was used as the test crop. The parameters observed were soil properties (pH, exchangeable H (H+), exchangeable Al (Al3+), exchangeable Ca (Ca2+), cation exchange capacity (CEC), available P (as P-Bray1)) and maize growth (plant heights and yield). The results show that the types of OA treatments had no significant effect on soil properties and maize yield; in contrast, the concentrations of OA levels were able to improve soil properties as indicated by a significant effect on pH, H+, Al3+, Ca2+, CEC, available P, and increased maize yield. An increase in soil pH due to the addition of OAs to the direct application of PR could increase Ca2+ and CEC and decrease Al3+ and H+, while increasing available P for plants. Although not significantly different, oxalic acid was able to improve the observed soil properties and maize yield, followed by citric, humic, and succinic acids. The maximum OA concentration was 126.9 ppm. We can say that the main finding of this research is that oxalic, citric, humic, and succinic acids at a concentration of 126 ppm can be applied to phosphate rock. In Indonesia, humic acid has been widely applied by farmers because it is easy to obtain. Therefore, it can be applied to phosphate rock.

“…The characteristics of ultisol soils in oil palm plantation areas in Bengkulu are low pH (4,20), low C-organic, and very low nutrient content of N, P, and K-dd (Nurmegawati et al, 2020). Acidic soils such as ultisols have high mineral content, and Al inhibits root growth and decreases photosynthesis (Hidayah et al, 2020).…”

The development of oil palm nurseries in Bengkulu is constrained by plant media, such as ultisol soil, which has low nutrients. Nutrients in ultisol can be equipped by organic matters such as manure and liquid organic fertilizer (LOF). Moreover, the light intensity also could affect seeds growth. This research aimed to determine the improvement of oil palm in pre-nursery as affected by LOF, types of manure application, and shade to obtain the best treatment combination. The research was conducted from June until September 2021 in Beringin Raya, Bengkulu city. The study was arranged in a split-plot design in a completely randomized block design consisting of 3 factors with three replications. The main plot was shade percentage ((N1=50% dan N2=75%), the subplot was liquid organic fertilizer doses ((B1=0%, B2=5% and B3=10%), the sub subplot was the types of manure (P1=cow manure, P2=chicken manure, P3=goat manure, and P4= without manure). The observation was made on the growth components of oil palm seedlings until 3.5 months. There was an interaction between shade, LOF, and types of manure to the number of leaves. There was no interaction between LOF and types of manure. The shade did not affect the growth factors of the seeds. Applying 10% LOF can improve the growth of oil palm seedlings. Chicken manure has the highest variable value on the hump diameter and the number of leaves seedlings.
