Reducing the Dimension of Growth and Yield Characters of Sweet Potato (Ipomoea batatas L.) Varieties as Affected by Varying Rates of Organic and Inorganic Fertilizer

I.S. Salawu and A.A. Mukhtar

Abstract:
Bivariate correlation was carried out on the growth and yield characters of sweet potato (Ipomoea batatas L.) and was observed that number of branch of sweet potato at harvest is positive and highly correlated with vine length of sweet potato. Vine length of sweet potato is positive and highly correlated with number of leaves of sweet potato at harvest. No. of tuber/hill of sweet potato is negative and highly correlated with number of branch of sweet potato. Tuber fresh weight is positive and highly correlated with total dry matter of sweet potato at harvest. Tuber dry matter of sweet potato is positive and highly correlated with tuber fresh weight. Of the growth characters consider in the study, the Principal component analysis shows the reduction of the dimension of the variates from p = 4 to p = 2 component of m < p i.e., total dry matter explains most of the variation followed by vine length. Likewise, tuber fresh weight explain the variation in the yield character.
