Abstract
The results showed that the pH values of each coating substance formulation exhibited statistically significant differences. Notably, the highest pH value was observed in the coating substance mixed with CMC. Similarly, the viscosity of the coating substances showed significant variations, with the commercial coating substance having the highest viscosity. Following this, the coating substances mixed with CMC, HPMC, NaAlg, and PVP-K30 demonstrated progressively lower viscosities. To assess the uniformity of the coating, the surface characteristics of the seeds were visually examined. The results indicated that seeds coated with the commercial coating substance exhibited the highest coating uniformity. Subsequently, the uniformity levels decreased in the following order: seeds coated with a mixture of PVP-K30, HPMC, CMC, and NaAlg. For the seed quality test after coating, the results showed that all types of polymers had no statistically significant effect on the germination percentage and germination index. If further studies are conducted on the types and concentrations of polymers, it is possible to develop seed coating formulations to delay germination.
