Corn Husk Color and Harvesting Date on Seed Quality of Sweet Corn Insee 2

Abstract

The research aimed to study the development of corn husk color and suitable harvesting date on seed quality of Insee 2 sweet corn variety. The experiment was planned by Completely Randomized Design (CRD) with 6 treatments, using the different stages with 6 stages of corn husk color. The results indicated that the appropriate stage of corn husk color development was the husk is white and pale yellow, similar to rice straw. There are a few dark spots (5Y 8/4) and the seeds are yellow and dry (5Y 8/10). The seeds are starting to fall apart. The optimum harvest time is 95 days after planting as the seeds have the highest vigor. The highest percentage of germination in the soil was 61.50 percent. The height of the seedlings and root lengths were 20.50 and 7.25 centimeters, respectively. In addition, it had the least moisture inside the seeds, at 58.58 percent, followed by the harvest period at 90 days after planting due to the medium germination percentage in the soil was 35 percent, but there was a tendency for the highest germination speed index in the soil to be 9.50 plants per day.
