Not only sprouting culture but plant growth condition has been decided in most cases by judging the desirable characteristics such as big growth and abundant harvest. However, the sprout is cultured under inhibitory condition which is shading culture. So it tends to breakdown and decay before long. The sprouting condition has been also accompanied with evaluations including the principle contradiction, that is, "The one which grows up early decays rapidly and the one which is late growth does not grow to be big. " Here, the optimization was conducted by parameter design considering weight change versus the culture time to be dynamic SN ratio on the growth curve as an evaluation to decide the sprouting condition.
