Abstract: Background and Objective: Maize seed production systems are nowadays used to try to conduct early harvests and thereafter submitted for seed processing and marketing within a short period of time. Thus, the experiment was aimed to evaluate the effect of harvesting time and drying management on maize storability and seed vigor after early harvested. Materials and Methods: The experimental design was arranged in 2×4 factorial in Randomized Complete Block Design (RCBD) with four replications. The effect of two different harvesting times were H1: 100 Day after emergence (DAE, R5), H2: 110 DAE (R6) and four drying temperatures (T1: 30°C, T2: 35°C, T3: 40°C, T4: 45°C) were observed. Then, seed qualities and vigor were tested. Results: The H2 had the highest speed of germination. At 0 month, the highest germination percentage, speed of Germination, shoot length, Root Length (RL), Seedling Dry Weight (SDW) and seedling growth rate were obtained at 45°C. At 6th month of storage, the highest germination percentage, AA-test, RL and SDW were obtained at 35°C. Conclusion: The experiment could be concluded that seed drying at 45°C can be used for immediate use of seeds without storage. For storability, the anticipation of harvest and seeds drying at temperatures of 35°C result in maize seeds that have the ability to grow into normal seedlings in field conditions.
