Abstract
Experiments were conducted to find out the optimum amount of compost and tillage depths in pepper cultivation. Red pepper was grown in different plots with 10 cm, 30 cm, and 50 cm in tillage depth, and was applied with 1 ton, 3 ton, and 5 ton $10a^{-1}$, respectively. The pH value in soil showed lower level after experiment than before experiment, however, the contents of the EC, Av. $P_2O_5$, K, Ca, Mg, and Na were increased after experiment. The chemical contents in soil after experiment showed higher level in compost 5 ton $10a^{-1}$. The growth of red pepper in field was enhanced in the compost treatment of 3 ton, 5 ton $10a^{-1}$, and tillage 50 cm plot. In tillage 10 cm plot, yields of red pepper showed the highest amount as 5,880 kg $ha^{-1}$ with compost 3 ton $10a^{-1}$. In tillage 30 cm plot, the yields of red pepper showed the highest as 5,610 kg $ha^{-1}$ with compost 5 ton $10a^{-1}$. The T-N contents and uptake in the red pepper plant increased in the compost in 3 ton $10a^{-1}$ and 5 ton $10a^{-1}$ compared to 1 ton $10a^{-1}$. These results suggest that different amounts of compost should be applied when we cultivate crops with different tillage depth.
