Abstract

This study presents the results of a field bio-efficacy evaluation to assess the impact of Enersol® LDG, a mineral fertilizer containing leonardite and humic acid, on the growth and yield of pechay (Brassica rapa) in Puypuy, Bay, Laguna, Philippines. In pechay production, there is a need for a plant food supplement that facilitates immediate nutrient absorption. Leonardite-based products have been used to improve soil properties and to help plants withstand biotic and abiotic stresses. Leonardite is an important raw material in the manufacture of commercial products rich in humic and fulvic acids. An experiment in a randomized complete block design with three replications was conducted, with different combinations of Enersol® LDG and inorganic fertilizer applied basally at seed sowing. Results showed that the combination of Enersol® LDG and inorganic fertilizer significantly increased the total fresh yield of pechay compared to other treatments. However, reducing the amount of inorganic fertilizer resulted in lower yields, regardless of the Enersol® LDG application rate. The marketable yield and percent marketable yield were also significantly higher in plants treated with Enersol® LDG and inorganic fertilizer combinations compared to the control and Enersol® LDG alone. Based on these findings, it can be concluded that Enersol® LDG, when combined with inorganic fertilizer, significantly enhanced the growth, and yield of pechay. Further research is recommended to explore optimal dosage and application methods for maximizing pechay production using Enersol® LDG.
