Hot pepper growth in no-tillage cultivation on recycled ridge was increased by 22% compared with tillage cultivation. At 3 years after no-tillage cultivation, hot pepper growth was increased by 12% compared with tillage cultivation. Dry weight of unripe hot pepper at 2 years of no-tillage cultivation was 348.4 kg/10a increasing 16% compared with tillage cultivation while dry weight of unripe hot pepper was decreased at 3 years of no-tillage cultivation. Bacteria flora at 2 years of no-tillage cultivation was significantly increased compared with tillage cultivation. Bacteria flora was not significantly different at 3 years of no-tillage cultivation. Actinomyces flora at 2 years of no-tillage cultivation was significantly increased compared with tillage cultivation. Actinomyces flora was decreased at 3 years of no-tillage cultivation. Fungi flora at 2 and 3 years of no-tillage cultivation was increased by 1.3 and 1.7 times respectively, compared with tillage cultivation. Generation amount of carbon dioxide at no-tillage cultivation soil was remarkably decreased by 41% compared with tillage cultivation. Population of animalcule in early stage of hot pepper soil was 2 species and 6 individuals on Collembola and Acari at tillage cultivation. Population of animalcule in hot pepper soil was 5 species and 11 individuals including Chilopode at one year of no-tillage cultivation. Population of animalcule in hot pepper soil was 3 species and 5 individuals including Coleoptera and Chilopode at 2 years of no-tillage cultivation. Population of animalcule was 4 species and 40 individuals including Hypogastrurigae and 8 species and 97 individuals including Earwig (Labidura japornica) at 46 days after transplanting on tillage cultivation. Population of animalcule was 9~10 species and 101~107 individuals on no-tillage cultivation. Nature status for environmental change as index organism was 19 points and 33 points, at tillage and no-tillage cultivation, respectively. These results indicate that no-tillage agriculture of korean-style on recycled ridge plays a very important roles on pepper growth, biodiversity of animalcule, and greenhouse gases at plastic film greenhouse soil in no-tillage systems.

This study was carried out to investigate the hot pepper yield, chemical properties of soil and distribution of animalcule with split irrigation and input of organic matter under no-tillage hot pepper green house condition. After experiment, soil pH maintained range of 5.6~6.2 in whole treatments. Organic matter content of soil was range of $32{\sim}42g{\cdot}kg^{-1}$. Soil salinity (EC) content of soil was range of $1.0{\sim}2.7dS{\cdot}m^{-1}$. Exchangeable cations in soil were range of $0.08{\sim}0.24cmol^+{\cdot}kg^{-1}$ in K, $9.5{\sim}12.8cmol^+{\cdot}kg^{-1}$ in Ca, and $2.7{\sim}3.2cmol^+{\cdot}kg^{-1}$ in Mg. Avaliable phosphorus ($P_2O_4$) content in soil was range of $1,011{\sim}1,137mg{\cdot}kg^{-1}$. Yield of pepper was more decreased in treatment of soybean cake fertilizer than no-treatment of soybean cake fertilizer. Yield of pepper in treatment of soybean cake fertilizer was increased at 33% of standard fertilizer application. Yield of pepper in no-treatment of soybean cake fertilizer was increased at 33% and 66% of standard fertilizer application. Number of fruits was increased range of 12.5~34.9% at half division irrigation compared with whole quantity irrigation. Yield of pepper was increased range of 13.5~34.4% at half division irrigation compared with whole quantity irrigation. Nine index of nature status and 271 Individual were captured in treatment of soybean cake fertilizer. Five index of nature status and 54 Individual were captured in treatment of soybean cake fertilizer. Nature status for environmental change as index organism was 11 points and 5 points, at treatment of soybean cake fertilizer and no-treatment of soybean cake fertilizer, respectively.
