Calcium carbonate is an active ingredient in agricultural lime. It is commonly found in rocks and the main component of pearls and shells of marine organisms, snails, and poultry eggs. Calcium carbonate forms such as lime, eggshells, and oyster shells were utilized to investigate its effect on the growth and yield characteristic of purple sweet corn planted in acidic upland soil in Quevedo Maayon Capiz Philippines. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four treatments replicated three times. The treatments used were the following: T1- soil (control), T2- soil + lime, T3- soil + eggshell, T4- soil + oyster shell. Results revealed no significant difference in the plant height at 15, 30, 45, and 60 days after planting (DAP), leaf area index (LAI), herbage weight, length, diameter, and weight of ears. Numerically, purple sweet corn applied with eggshells produced the tallest plant, longest and widest ears, while those applied with oyster shells got the highest leaf area index. Thus, the inclusion of eggshells and oyster shells has the potential in agricultural liming with appropriate rates of chemical fertilizer to obtained maximum yield in purple sweet corn production.
