Correlation Analysis of Aloe Vera-Based Liquid Organic Fertilizer and SP-36 Application on The Growth of Sugar Palm Seedling (Arenga pinnata Merr.)
Abstract
This study aimed to analyse the relationship between vegetative growth parameters of sugar palm seedlings after administration of Aloe vera-based liquid organic fertiliser combined with SP-36 fertiliser using correlation analysis. This experiment used a randomised block design consisting of five treatment levels & five replications. Data were analysed using Pearson correlation analysis with SPSS version 25. The findings revealed that these treatment combinations generated relationships classified as strong to very strong among the observed growth parameters. A very strong correlation was identified between the number of leaf sheaths and both plant height and stem diameter, highlighting the crucial function of leaves in enhancing photosynthetic activity and biomass production. In addition, plant height exhibited a very strong association with stem diameter, indicating an interconnection between primary and secondary growth processes. Statistical analysis demonstrated that several variables had a significant influence (Sig. F < 0.05), particularly in the relationships involving leaf sheath number with plant height and stem diameter, as well as between plant height and stem diameter. Although higher LOF dosages tended to promote plant growth, there were signs of a threshold beyond which nutrient uptake efficiency may decline. Overall, the integration of Aloe vera-based LOF with SP-36 fertiliser shows promising potential to improve vegetative growth in sugar palm effectively, and may represent a sustainable fertilisation approach. The optimum response was observed at moderate LOF doses, indicating that balanced nutrient management is essential to maximise vegetative growth efficiency in sugar palm seedlings.
