Effect of Organic Amendments in Sandy Soils on Increasing Tomato Yield at Rooftop Garden

Urban Farm DB summary

This study examined the effects of different organic amendments on BRRI Hybrid Summer Tomato 4 grown in sandy soil on a rooftop. Treatments included sand with compost, coco peat, household ash, or rice husk. Compost (T1) was superior for plant height, fruit number, and yield, while household ash (T3) resulted in the highest plant tissue phosphorus and potassium. The findings suggest that organic materials like ash and compost can increase tomato yields in rooftop gardens and mitigate sandy soil limitations.
