Harvesting process by seed drying temperature becomes a very important process to decrease seed moisture content down to a desired level that could maintain seed quality. Thus, the experiment was aimed to evaluate the effect of harvesting time and drying temperature on maize storability and seed vigor after early harvested. The experimental design was arranged in 2x4 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 ºC, T2: 35 ºC, T3: 40 ºC, T4: 45 ºC) were observed. Then, seed qualities and vigor were tested. From the experiment, H2 had the highest speed of germination. The seed can be used immediately without storage by drying temperature at 45 ºC. Whereas for storage, seeds should be dried at 35 ºC.
