The Role of Soil and Plant Nutrition on Oil Palm Bud Rot Disease: A Review
Bud rot disease (BRD) is a major threat of the oil palm crop in tropical America caused by Phytophthora palmivora. The role of plant nutrition on plant diseases management has been studied and reported in many crops worldwide. The objective of this paper is to review on the relationship between the soil properties, the plant nutrition and the integrated agronomic management on the susceptibility of the palms to BRD. In Colombia (East and West zones) was found that soil parameters related with poor drainage increased the predisposition and the incidence of the BRD. The areas with poor drainage were characterized by high clay contents and bulk density, and low infiltration rates and hydraulic conductivity. By the other hand, it was reported that high levels of nitrates, aluminum and manganese accompanied with low N, P, K, Mg, Ca, S and B content, and their imbalance in the soils and in the plant enhanced the predisposition to BRD. As a successful management practices reported to decrease the incidence of BRD were the drainage improvement, the soil compaction reduction, the incorporation of soil amendments and the balanced nutrient management in the different crop stages. The former recommendations must be accompanied with an optimum nursery management, early detection and treatment of affected palms, and finally the monitoring and control of Rhynchophorus palmarum pests. In general, it was observed that in some Colombian regions that the integrated soil, water and palm nutrition management decreased the susceptibility to BRD and gave the optimum conditions for a good growth and yield expression.
