The Growth Response of Oil Palm Progeny (Elaeis Quineensis Jacq.) at Various Levels of Fertilization and Types of Planting Media

Introduction

The oil palm industry is a significant contributor to the global economy, with Indonesia and Malaysia being the largest producers of palm oil. However, the growth and production of oil palm are influenced by various factors, including fertilization and planting media. The selection of appropriate seeds is crucial in increasing the growth and production of oil palm optimally. In this study, we aim to examine the effect of various levels of fertilization and the type of planting media on the growth of oil palm progeny.

Research Objectives

This study has four main objectives:

Determine the quality of the performance of oil palm seedlings at different levels of nutritional adequacy. This objective aims to evaluate the effect of fertilization on the growth and development of oil palm seedlings.
Test the effect of various types of planting media on the quality of the performance of oil palm seeds. This objective aims to evaluate the effect of different planting media on the growth and development of oil palm seedlings.
Test the performance of the quality of various oil palm progeny. This objective aims to evaluate the effect of different oil palm progeny on the growth and development of oil palm seedlings.
Assess the effect of interaction between two and three factors on the quality of the performance of oil palm seeds. This objective aims to evaluate the effect of interaction between fertilization, planting media, and oil palm progeny on the growth and development of oil palm seedlings.

Research Methods

The study was conducted at the Bah Lias Research Center, using a group design and split-install plot design consisting of six replications. The main factor in this study is the fertilization treatment with three levels:

Z = without fertilization: This treatment aims to evaluate the effect of fertilization on the growth and development of oil palm seedlings.
n = half standard fertilization: This treatment aims to evaluate the effect of half standard fertilization on the growth and development of oil palm seedlings.
O = standard fertilization of the research center: This treatment aims to evaluate the effect of standard fertilization on the growth and development of oil palm seedlings.

Subplot factors involve three types of media:

PT = Peat from Kuala Hulu, Labuhan Batu: This treatment aims to evaluate the effect of peat media on the growth and development of oil palm seedlings.
SS = Land (50%): Sand (50%): This treatment aims to evaluate the effect of land-sand media on the growth and development of oil palm seedlings.
SO = Land: This treatment aims to evaluate the effect of land media on the growth and development of oil palm seedlings.

Sub-plot consists of 21 oil palm progeny. The parameters measured for vegetative growth include plant height, the number of green leaves, stem diameter, and cross section of the petiole, while the physiological parameter includes the total leaf chlorophyll content, the percentage of selected vigor seeds, as well as the nutritional levels of N, P, K, Ca, and Mg on leaf.

Results and Analysis

From the statistical analysis of vegetative growth parameters, all factors tested - fertilizing, type of media, and progeny - showed a significant effect on plant height, the number of green leaves, stem diameter, and cross section of petiole 10 months after planting. The quality of seed performance is divided into three categories: quality-1 (4 combinations), quality-2 (10 combinations), and quality-3 (11 combinations).

Further analysis shows that the interaction between the fertilization level and the type of media has a very significant effect on the chlorophyll content, as well as the level of nutrition N, K, and the percentage of selected vigor seeds. In peat media, the influence of the nutrient level P is very significant, while the interaction between the progeny and the fertilization level has a significant effect on the total content of leaf chlorophyll.

Conclusion

From the results of this study, it can be concluded that the type of media, fertilization levels, progeny, and interactions have a significant influence on the quality of the performance of oil palm seeds. Vegetative growth parameters such as plant height, green leaves, stem diameter, and cross section of petiole at the age of 10 months after planting greatly determine the assessment of the quality of seed performance. Certain combinations such as FSON, FSOD, USON, and USOD are identified as the best quality, while a combination with peat or lands of land shows the lowest quality.

This study provides important insights for the development of better palm oil cultivation by taking into account the appropriate environmental and nutritional factors, so as to increase the results of oil palm production on a sustainable manner.

Implications of the Study

The findings of this study have significant implications for the oil palm industry. The results suggest that the type of media, fertilization levels, and progeny have a significant effect on the quality of oil palm seeds. Therefore, oil palm producers should take into account these factors when selecting seeds for planting. Additionally, the study highlights the importance of interaction between fertilization, planting media, and oil palm progeny on the growth and development of oil palm seedlings.
