1) Establishment of labour saving integrated mechanization culture system in seasme (1) Integrated mechanization culture system utilizing multi-functioned planter under non-mulching condition To investigate optimum seeding rate, 3, 5, 7 kg/ha of sesame seeds were released using multi-functioned plan

1) Establishment of labour saving integrated mechanization culture system in seasme (1) Integrated mechanization culture system utilizing multi-functioned planter under non-mulching condition To investigate optimum seeding rate, 3, 5, 7 kg/ha of sesame seeds were released using multi-functioned planter, rotary cultivator, binder, thresher, seed grader and automatic packer unde rnon-PE film mulching condition. Mechanization culture system could save 78 percent labour hours and 7 kg/ha seeding was optimum to get the highest yield. (2) Establishment of integrated mechanization culture system under PE film mulching and non-mulching condition Nine kg/ha seeding showed highest yield of 1,157 kg/ha under non-mulching dense standings system compared to the other seeding rate. Labour saving effects were 62 percent in black PE film mulching and 76 percent in non-mulch under the mechanization system culture. Three times of tractor rotary cultivating was recommendable for good sesame growth especially in vegetative growing stage compared to that of non-cultivating plots showing worse standings and plenty of weeds. (3) Establishment of integrated mechanization culture system utilizing multi-functioned seed planter Mechanization culture under non-mulch showed dense plant population but shorter in plant height with lesser number or branches and capsules per plant compared to those of conventional PE film mulch. Phytophthora blight and lodging of non-mulch was much slighter than PE film mulch. Tractor row planter of barley utilized until 1997. But it was difficult to adopt for the reason of poor standings and germination. Because the most of arable upland of Korea are composed sloped hilly area, the machine can not cultivate even soil depth for seeding. Newly developed multi-functioned seed planter in the spring of 1998 showed not only satifactory condition of standings and germination of seeds in sloped upland field but also was well adopted to larger or smaller sized crops of seeds. Six kg/ha amount of seed planting under non-PE film mulch was appeared 10 percent higher yield than that of conventional PE film mulch with 684 kg/ha. 2) Development of seed pellet technology (1) Investigation priming methods To avoid planting under the condition of lower soil moisture and air temperature in sesame planting season, priming and infusion treatments were released and investigated. Priming at 150 mM KCl and 0.5 M NaCl showed higher and faster germination rate than non treatment. Germination was feasible under 5 percent soil moisture content in sandy loam soil but was not germinated under lower than 7.5 percent soil moisture in clay loam soil. High germination percent were recorded under PEG -1.1Mpa in lower temperature, in dried and higher moisture contented soil of sandy and clay loam. Under optimum temperature, seed priming with potassium chloride 150㎛ in dried clay loam soil, potassium phosphate monobasic 150㎛ or calcium nitrate 250㎛m in dried sandy loam, and PEG -0.5Mpa in higher moisture content of both sandy and clay could improve significantly germinability. Under high temperature, potassium phosphate tribasic 50㎛ of clay loam or potassium phosphate monobasic 150㎛ of sandy loam soil was appeared efficient priming methods however the seed priming was not effective in high moisture content soil condition. (2) Investigation pelleting methods To save labouring hours of thining, materials of solid bodies and their mixture for pellet seeds and optimum condition for polymer were investigated. Vermiculite, talcum and peatmoss were appeared excellent in seed surface formation and it is hardness. The smaller and lighter particle of solid bodies were the better for pellet formation. Angle of revolving drum and speed of revolution were important for successful formation of pellet seed. Mixture combination of solid bodies of clay, peatmoss and talcum or vermiculite and talcum were superior in shape and hardness. (3) Searching microorganism for control soil born diseases 3,197 microorganisms were collected from 66 locations and selected 35 bacteria of Bacillus spp. which equiped good colonizing root zone ability under the seed pelleting system. Ten bacteria including E681 and E606 were appeared as surpassed bacterium among them with their wide spectrum of antibiosis. (4) Development of microorganism pelleting techniques Pelletized with M45, E681, E681 without chemicals but seed sterilized and priming with KCl showed good growth and higher yield in general. Pelletized with microorganisms were not appeared significant growth increase compared to control in newly reclaimed field but it was significantly in seedling stage in continuous seasme cropping field with lesser infection by diseases where the pathogens were not heavily accumulated. Pelletized with M45 showed 135 % yield increase in spite of non spraying chemicals through whole growing period in the experimental field. Population of E681 in pelleted seed was not reduced up to one year but population of M45 drastically decreased with increase of storing dates of pellet seeds. (5) Commercialization pellet seeds Optimum storing condition of pellet seeds were lower than 15℃ with lesser than 60 air moisture percent. Ninety percent germinability could be kept on least three months in those storage condition. Pelletized seeds were not only convenient in seeding but also saved seeds. Birds were not interested in pellet but interested in normal seeds. It was not necessary to cover soils on the pellet where optimum soil moisture. Pellet seeds were good for it would not easily move the position when heavy rainfalling but it was bad because the pellet seed were not well germinated in dried soil in period for it preservated for three months long. Optimum condition for pelleting sesame seeds is pelleting 400㎖ seasme seeds with 2,800㎖ crushed vermiculite at 60 mesh temporarily pouring into drum mixing slowly slowly 500㎖ of 0.5% PVA however this condition might be recommended to slightly modify when adopting to other crops.
