다국어 초록 (Multilingual Abstract)

This study was conducted to investigate the effects of fertigation level such as 50%, 75% and 100% N of standard amount of chemical fertilizer, and fertigation interval such as every irrigation, intervals of 1 and 2 weeks of piggery waste water(PWW) on the growth, yield of red pepper plant and the chemical properties of soil used. In early stage, growth of red pepper plant fertigated with PWW and that of red pepper plant applicated standard chemical fertilezer was the same, while it were increased as increasing application amounts of PWW, and later growth and total yield of red pepper plant were much more at 75% N fertigation of PWW. Inorganic content such as nitrogen, phosphate and potassium and chlorophyll content of red pepper leaves were increased as increasing fertigation amount of PWW. 50% fertigation level showed the lowest rate of fruit setting of red peper plant. For soil chemical properties, pH was slightly decreased, but available P₂O₅，and exchangeable K content were increased as increasing fertigatiai amount of PWW.
Because there was not statistically significant difference in the growth, the yield of red pepper and chemicl properties of soil used according to various fertigation intervals, and no need to artificially supply PWW, therefore fertigation by single automatic system with tensiometer was thought to be better.
