Abstract

The research examined the impact of degradable mulch on soil characteristics and development of green bean.Three types of degradable mulches:biodegradable, oxo-degradable, and paper degradable mulchwere comparedwithblack polyethylene mulch andexposed soil. The results showed a significant increasedin soil temperature, with polyethylene and oxo-degradable mulch, while biodegradable mulch exhibited lower temperatures compared to other mulchingtretments. Application different mulching treatments increased soil moisture content significantly compared to the exposed soil. Organic carbon content, soil nutrient content, electrical conductivity and pH, were not significantly affected among different mulch treatments. However, differences in soil microbial populations were observed, with biodegradable mulch promoting higher fungal counts compared to othertretments. Bean growth measurements revealed no significant differences in plant height, but leaf area and shoot fresh and dry weights were influenced by the type of mulch used. Oxo-degradable and paper degradable mulch resulted in larger leaf areas, and biodegradable mulch positively impacted shoot weights. The results also demonstrated that polyethylene ,oxo-degradable mulch and paper degradable mulch treatments significantly increased bean yield compared to exposed soil and biodegradable mulch treatments. Visual mulch degradation evaluation indicated that biodegradable and paper degradable mulches had higher degradation percentages compared with polyethylene and oxo-degradable mulches. These findings emphasize the importance of using environmentally friendly mulching materials, such as biodegradable and paper degradable mulches, in horticulture to reduce environmental impact and promote sustainable food systems.
