Abstract

Oil palm (Elaeis guineensis Jacq.) is an important plantation commodity that makes a significant contribution to Indonesia's economy. One of the macro nutrients that plays a role in supporting plant growth is potassium (K), which is involved in various physiological processes. The effectiveness of nutrient utilization is not only determined by the amount of fertilizer applied but also influenced by the application method, especially during the early seedling phase. This study aims to examine the growth response of oil palm seedlings to variations in KCl fertilizer doses and different fertilizer application methods during the pre-nursery phase. The experiment was arranged using a Factorial Randomized Block Design (RBD) with two treatment factors, namely KCl fertilizer dose and fertilizer application method, each with three replications. The KCl doses consisted of five levels, while the application methods included watering, broadcasting, and localized application (pocket). The observation data were analyzed using analysis of variance and followed by Duncan Multiple Range Test (DMRT) at a 5% level if there were significant differences. The results of the study showed that there was no interaction between the dose of KCl fertilizer and its application method on all observed oil palm seedling growth parameters.

Abstract

This study aimed to determine the response of oil palm (Elaeis guineensis Jacq.) seedlings to KCl fertilizer dosage and drought stress in the early pre-nursery seedling phase. The experiment used a factorial randomized block design (RBD) with a combination of KCl dosage and soil water content, replicated three times, with observations made on the parameters of corm diameter, leaf width, and number of leaves. The observation data were analyzed using analysis of variance and continued with the Duncan Multiple Range Test (DMRT) at the 5% level if there were significant differences. The results showed that KCl dosage, drought stress, or the interaction of the two did not have a significant effect on corm diameter and number of leaves. Conversely, drought stress individually had a significant effect on leaf width, while KCl dosage showed no significant effect. The interaction between KCl dosage and drought also had no statistical impact on leaf width. These findings indicate that in the pre-nursery phase, oil palm seedling growth in corm diameter and number of leaves was relatively stable across treatments, while leaf width was more sensitive to water limitations. The implications of this study indicate the importance of managing the availability of water in the planting medium to support leaf growth, while the administration of KCl at the tested dose has not provided a significant effect on the initial phase of seedling growth.
