Productivity of Cauliflower Crop under Biodegradable Mulch

This study evaluated the effects of various mulching materials, including biodegradable mulches (BDM), plastic mulches (PM), and polypropylene mulch (PPM), on soil temperature, cauliflower growth, and yield. The experiment was conducted in a randomized block design with eight treatments, including a no-mulch control. Results indicated that BDM and PM significantly increased soil temperatures, particularly at deeper soil levels, compared to the control. Among the treatments, BDM was more effective in stabilizing soil temperature fluctuations. Growth parameters such as plant height, curd diameter, and yield per hectare were enhanced in the mulched treatments, with PPM showing the highest yield. However, despite moderate yields, BDM treatments incurred higher cultivation costs, resulting in lower net income compared to PM and PPM treatments. The study suggests that BDM, being environmentally friendly, could be a viable option for farmers if its acquisition cost is subsidized or reduced.
