Evaluation of Different Mulching Materials on Soil Temperature and Tomato Yield

Abstract Preview

Mulching can modify soil temperature and moisture for improved crop growth. This study evaluated mulching effects on soil temperature and tomato yield. Four mulching treatments were tested: rice straw, sawdust, black plastic, and grass mulch compared to bare soil control. Soil temperature was monitored at 5cm and 15cm depths throughout the growing season. Results showed that organic mulches reduced maximum soil temperature by 4-6 degrees Celsius compared to bare soil, while black plastic increased temperature by 2-3 degrees Celsius. Soil moisture retention was highest under rice straw and grass mulch. Tomato yield was significantly higher under rice straw mulch (28 t/ha) compared to bare soil (18 t/ha). The study recommends rice straw mulching for tomato production in hot climates.
