The purpose of this study was to find out the optimum SMP carriers in seeds of 12 pepper cultivars to alternate Micro-eel E. It showed that calcium carbonate caused the lower germination rates in proportion of water volumes and the radicle protrusion during priming period. Micro-cel E induced also the radical protrusion, even though it shortened $T_{50}$ in Wang cultivar, in proportion of water volumes. Diatomaceous earth shortened both $T_{50}$ and Mean days germination(MDG) in Choyang and Hyangchon cultivars, although it caused the radicle protrusion in treatment of $1.5{\times}$ water proportion. In Wang cultivar, Diatomaceous earth shortened $T_{50}$ by 0.60 and 0.05 days at 1.0 and $1.5{\times}$ water proportions respectively compared to the Micro-cel E at 5.0 and $7.0{\times}$ water proportions. Therefore, it could be suggested that Diatomaceous earth for the carrier might be suitable in pepper cultivars to alternate Micro-cel E, and $1.0{\times}$ water proportion should be available for processing.

Pre-sowing treatments of tobacco seeds (cv. NC82) were evaluated as a means of improving the speed of emergence, early seedling growth and uniformity of the seedlings. Seeds were treated through the use of polyethylene glycol 6000(PEG), solid matrix priming(SMP), chilling and dark-preincubati(DPI). Under the laboratory condition of 15$^{\circ}C$, all the treated seeds germinated more rapid and the time to 50% germination(T50) reduced than control. Among the treatments, SMP was the best to reduce the T50 for germination. All the treatments did not affect the final germination percentage, while the chilling showed of little benefit for germination and T50. Under the greenhouse condition, seedling from SMP emerged earlier and more uniformity and also greater mean fresh and dry weight showed than other treatments. The advantage of T50 from SMP was affected more in temperature than in water content of Agro-Lig during the treatment.

Treatment duration of 12 pepper species by 3, 5, 7 days examined result, optimum processor of 12 pepper cultivars and carrier : water proportion was difference in species. However, radicle protrusion during priming(RPDP) does not happened and heightens germination rate, and Wang and Manitta species were 1:3(ratio), 7 day by treated that can shorten $T_{50}$, and all of the 10 cultivars were regard to processing of 1:7(ratio), 3 days was make satisfactory progress. Also cultivars of Jongggip was investigated by cultivars which germination rate and $T_{50}$ according to treatment duration and water proportion was irregular tendency than other cultivars. It was suggested that $20^{\circ}C$ was stable to radical protrusion and improved germination, while from $15^{\circ}C$ to $35^{\circ}C$ examined.

This study was carried out to develop and investigate integrated mechanization system for culture of carrot. Compared with the conventional hand planting, use of a mechanical planter for pelleted seeds resulted in a saving of planting time by 225 hours. An additional saving of 460 hours was obtained for thinning the seedlings. Besides seeds could be saved by 72%, planting and thinning be done only in 35 hours per ha field when the pelleted seeds were planted with a planter. Work hour reduced by adopting the mechanical planting of pelleted seeds sharply contrasted to that of 720 hours required for hand-planting the thinning hours, resulting in a reduction of labor by more than 95%. SMP followed pelleting tended not only to increase the percentage of seedling emergence in the field but to induce an a day earlier germination.

The purpose of this study was to find out the optimum germination temperature and dehydration period at SMP processing, and applies 3 kind of seed treatment and compares yield with stand establishment of seeds of 12 pepper cultivars. It was showed that all 12 cultivars of nontreated seed does not entirely germinated in $15^{\circ}C$. It was that SMP seed germination rate 77(Yeomyeong)~100% (Deawang) high, and seeds 12 cultivars was tendency high by more than 93% at all temperatures excepting Bugang($35^{\circ}C$, 85%) and Yeomyeong($15^{\circ}C$, 77%). Dehydration condition of result were Gumsure, Dongbang Jonggagip, Hyangchon, Yeomyeong, Kwangbok, Wang by which 3 hours in $45^{\circ}C$ were proper, which 6 hours in $35^{\circ}C$ were proper Manitta, Joyang, and judged that 12 hours in $25^{\circ}C$ were proper in Bugang, Dabotap, Deawang. It was reported that water percentage of moisture content change of pepper seed by dehydration was difference a little in species, but was judged by 3-6 hours in $45^{\circ}C$. There was compared to SMP, Osmopriming, pH control by stand establishment were shown pH control of Hyangchon, Dabotap species was nontreated, osmopriming treatment. Also, Kwangbok species was tendency that stand establishment was low, and Deawang was good than other species. Yield of nontreated of yield day was tendency, and miss planted rate also appeared high for 90 day. There was difference in species, and processing of pH control and osmopriming was not shown stand establishment that is stabilized in all species. SMP processing condition could bring security of stable stand establishment in all species, and was considered that research that was under various environment condition should be proceeded conclusively.
