We investigated the effect on blueberries' growth by mulching pine cones and comparing them with the different treatments. Five treatments, shredded pinecone, shredded pinecone with sulfur, sulfur only, and pine needles, and without any treatment (control), were applied in the soil. We measured plant growth (height and crown width), physiological properties such as chlorophyll content and maximum quantum yield (Fv/Fm), and soil properties (pH, moisture content) at 5 months of cultivation from treatments). The height of plants treated with pinecones was the greatest at 21.43%, followed by the treatment of pinecone with sulfur at 19.23%. The crown growth was highest (34.26%) when they were treated with pinecone with sulfur. However, growth rates among the treatments were not significantly different. The chlorophyll content was high in pinecone with sulfur and pine needle treatment. Fv/Fm was generally high in the case of mulching pine cones, and the sulfur-only treatment was low. The soil moisture content was the highest in the case of mulching pine cones, followed by mulching pine needles. As for the soil pH, the treatment of the pine cone was the lowest, followed by the pinecone with sulfur and pine needle treatment. Taken together, blueberries grew actively in the case of mulching pine cones, and there was also an effect of improving soil miniaturization and reducing pH.
