Abstract

Cultivating plants in organic agriculture requires the same level of care in seed coating technology as in conventional farming. The physical characteristics of six polymers indicated a slight alkaline nature. Other polymers showed similar viscosities and increased in viscosity as the concentration level increased, with xanthan gum exhibiting the highest viscosity at the same concentration level. Gelatin, carrageenan, sodium alginate, and gum arabic dissolved well when in film form. Coating seeds with 0.2% w/v sodium alginate showed a significantly higher radicle emergence percentage, radicle emergence speed, germination rate, germination speed, shoot length, and root length compared to non-coated seeds. Therefore, it is recommended to use 0.2% w/v sodium alginate for coating organic tomato seeds
