Seed pelleting have successfully been used in many crops for better crop establishment and for mechanizing seeding process for small crop seeds in developed countries. In this experiment various pelleting materials and binders were tested to get basic information on the shape, hardness and germination of pelleted seesds of cabbage (cv. Seoul Beachoo) and rice (cv: Ilpoom).
PLL-11, paper clay, lime and coal ash were good materials to make smooth shape of the pellets with pelgel and AG-11 as binders, and PLL-11 as material and pelgel and AG-11 as binders were the best among them in consideration of shape and hardness together. The hardness of the pelleted seeds were differed with each other depending on both of the pelleting materials and binders. Pelleted cabbage seeds coated by pelgel as binder with different materials showed lower germination percentge than control in general, but the seeds pelleted by PLL-11 with different binders showed no restraint effects. When the cabbage seed pelleted by PLL-11 with pelgel as binder showed almost same germination percentage as control. The pH and electrical conductivity of the extract from bentonite and zeolite were very higher than other materials tested and germination percentage showed a little lower than control when the cabbage seed planted on the filter paper damped with the extract. As a result, PLL-11 as pelleting material and pelgel and AG-11 as binder appeared the good materials to make pellets of cabbage seeds and rice in consideration of shape, hardness and germination.
