In educational material cited by on Tuesday (May 5, 2026), PPKS explained that abnormal oil palm seedlings are generally caused by two main factors: genetic conditions and improper nursery treatment. If left untreated, such abnormalities could reduce plantation productivity in the future. From a genetic perspective, several symptoms require close attention, including vivipary (germination inside the fruit), sterility, twisted or spiral leaf growth, and shortened rachis that makes seedlings appear stunted. Meanwhile, nursery management issues commonly found in the field include incorrect planting depth, compact or unscreened planting media, insufficient or excessive watering, and poor-quality water such as saline or contaminated water sources. PPKS also identified damaged nursery bags, acidic soil conditions, pest attacks, improper pesticide application, and overcrowded spacing as additional contributors to seedling abnormalities. The research institution stressed that even superior seeds can develop abnormally if nursery management practices are inadequate. Therefore, routine selection is considered a critical stage that should never be overlooked. “Selection must be conducted regularly at the ages of 3, 4, 8, and 12 months to ensure only healthy seedlings proceed to the next stage,” PPKS stated in its educational guidance. PPKS further recommended several corrective actions, including removing seedlings showing stunted, curled, or twisted growth symptoms, improving planting media quality, drainage systems, and irrigation management, as well as ensuring the use of clean, uncontaminated water. The institution also highlighted the importance of recording abnormal seedlings during each selection stage as part of continuous nursery evaluation and improvement efforts. Through consistent early selection and proper nursery management, PPKS expects oil palm plantation productivity to become more optimal and sustainable in the long term.
