Abstract
Modern agriculture faces numerous challenges that can have adverse effects on the environment, soil health and long-term sustainability. Practices like excessive tillage, heavy chemical use and monocropping can result in soil erosion, depletion of essential nutrients and loss of organic matter. This study was conducted to address these gaps where different production systems (conventional and regenerative) and nutrient management strategies (recommended fertilizer and 10% reduction of the recommended rate) were implemented. The study aimed to assess their impact on sweet corn growth and yield, the soil's chemical properties such as pH level, organic matter, nitrogen, phosphorus and potassium and assessment of the involved practices' economic profitability. The results revealed that the conventional production of sweet corn yielded promising results in terms of crop development and other agronomic characteristics. On the other hand, the imposed nutrient management strategies and interaction of the two factors did not affect the corn's productivity. Moreover, the soil's chemical properties were not affected by nutrient management strategies. Also, there was a notable increase in the soil's potassium content using the conventional production system. Nonetheless, the other soil chemical properties did not exhibit across the different production system. From an economic perspective, regenerative and conventional systems demonstrated positive profitability, with conventional farming slightly outperforming the other in terms of profitability. However. considering the potential of regenerative production practices to reduce input costs and their positive environmental impacts, which goes beyond monetary valuation, promoting such technology is a viable option for corn growers and other crop producers.
