Sweet corn is classified as one of the most promising high valued horticultural crop in the Philippines because of its short maturity and faster economic returns particularly for small farmers. It has been grown commercially, a profitable farming enterprise and a good cash crops with high year- round price. It has a short growth duration, thus, can grow four or more cropping a year. Similarly, there is high demand for sweet corn in the market and is expected to increase in the future. However, productivity and sustainability is the main challenge face by many farmers/growers due to heavy reliance use on inorganic fertilizer and synthetic pesticides has given rise to many ecological and health problems. Development of production management practices is needed to meet the increasing demand in the market as well to address the challenges for a safe and nutritious food for human consumption. Thus, this study was conducted to evaluate the effect of different fertilizer management practices on growth, yield and kernel quality of sweet corn. Results showed that growth parameters (plant height, leaf area, growth rate, and dry matter yield) and yield and yield components (ear height, ear weight of ear/plant with and without husk, fresh ear yield/plot with and without husk, and stover) were significantly increased with application of organic, organic-based and conventional fertilizer management practices. Application of conventional fertilizer management practice resulted to highest increase in starch and sugar content, while application of organic-based fertilizer management practice gave the highest protein content in the sweet corn kernel.
