The present study was conducted to establish the suppression condition of lateral root development for producing high-quality peanut sprouts. The result of Chamsiru or 6BA treatment on peanut sprouts 'Jopyeong' and 'Vietnam' showed that the higher concentration of the solutions showed the better effect for suppressing lateral root development, regardless of the kinds of lateral root inhibitor. Compared to Chamsiru, 6BA showed better effect for suppressing lateral root development, and the effect was more obvious for 'Jopyeong' than 'Vietnam'. The alternant irrigation of Chamsiru and 6BA solution could produce high-quality peanut sprouts by inhibiting bacteria activity in solution and promoting of hypocotyl and root growth, while suppressing the lateral root development. The treatment of mixture solution of $GA_3$ and Chamsiru improved the overall growth of peanut sprouts, and the effect was the highest in the treatment of '$GA_3\;50mg{\cdot}L^{-1}$ + Chamsiru $8.40mg{\cdot}L^{-1}$'.
