The study looked at how different types of fertilizers affect the growth of tomatoes in a polyhouse. They tested organic manures, chemical fertilizers, and biofertilizers over two years. The results showed that a mix of organic and inorganic fertilizers led to the tallest plants and the most fruits per cluster. Using vermicompost and biofertilizers resulted in the most branches and clusters per plant. Overall, combining organic manures with inorganic fertilizers led to the highest nutrient uptake by the plants.
