Effects of Seed Pelleting with Different Filler Materials on Physical Characteristics and Seed Quality of Carrot (Daucus carota L.)
Main Article Content
Abstract
The commercial cultivation, carrot seeds are pelleted and imported from foreign countries. As a result, farmers have to bear the high cost of the seeds. Therefore, this study was to the effects of seed pelleting with different filler materials on physical characteristics and seed quality of carrot. The Completely Randomized Design is used as the experimental design with 4 replications that consist of non-pelleted seeds and each group of 3 grams of seeds pelleted with 30 grams of calcium sulfate, or zeolite, or bentonite, or pumice. The results found that pelleting carrot seeds with calcium sulfate could help facilitate the forming of the pelleting substance around the seeds. Moreover, the pelleted seeds were found to dissolve in water well. Only the minority of the seeds became the abnormal seedlings when compared to seeds that were pelleted with other types of substances. At the same time, calcium sulfate had a 90% germination rate. The difference was statistically significant when compared to seeds that were not pelleted. Also, calcium sulfate enhanced the seedling growth. The calcium sulfate pelleted seeds had higher shoot length, root length, and seedling length when compared to seeds pelleted with other types of substance and those that were not pelleted. It could be concluded that calcium sulfate is the most appropriate pellet substance for carrot seeds.
