The effect of sawdust vermicompost extract on Syngonium podophyllum growth and nutrition

Abstract

This study investigated the effects of four concentrations (0, 250, 500 and 1000 ppm) of a sawdust vermicompost extract on the growth and nutrition of Syngonium podophyllum. The extract, which was prepared using non-aerated extraction methods with a 1:10 (v: v) ratio of sawdust vermicompost to water, was sprayed three times on the Syngonium plants. Extract improved the mineral nutrient status of the plants. When the vermicompost extract was sprayed on the Syngonium plants, they showed significant growth. Germination tests did not show that vermicompost extracts would cause any potential damage to the plants. The spray containing the 1000 ppm extract had a great effect on Syngonium growth. Plants grown in pots and treated with the 1000 ppm vermicompost extract exhibited higher height, leaf area, chlorophyll, shoot fresh weight, and shoot dry weight than plants receiving control treatments. This study confirmed that sawdust vermicompost extract positively affects Syngonium plant growth.
