Examining the Effect of Vermicompost and Crab Powder as natural fertilizers on the Height and Girth of the stem of Tomato Plants.

This study investigated the effectiveness of vermicompost and crab powder as natural fertilizers for tomato plant growth over a 30-day period. The results demonstrated that vermicompost significantly outperformed crab powder in promoting plant height and stem girth. By the end of the experiment, plants treated with vermicompost reached an average height of 26 cm and a stem girth of 3 cm, compared to 22.6 cm and 2.6 cm for those treated with crab powder. Vermicompost provided a more balanced nutrient profile, including essential macronutrients such as nitrogen, phosphorus, and potassium, which contributed to consistent and robust growth. In contrast, crab powder, while rich in calcium and chitin, lacked sufficient nitrogen and phosphorus, resulting in slower and less consistent plant development. These findings support the conclusion that vermicompost is a more effective fertilizer for tomato plants, highlighting the importance of nutrient balance in optimizing plant growth.
