Item Analysis of yield and its components in sweet potato (Ipomoea batatas L.)(Kerala Agricultural University, 1976) Pushkaran, K; Sukumaran Nair, P; Gopakumar, KAnalysis was carried out for studying the yield-component inter-relationship in seventeen varieties of sweet potato. Determination of the coefficients of simple and mutual correlations and path at the levels of the first and second order components reveals that an increase in the length of vine causes significant increase in tuber yield. But at the same time, the overall area of leaf should not be allowed to increase, because this character bears a negative relationship with yield. An ideal plant type with longer vines, w i i i i small, narrow and deeply lobed leaves with appropriate orientation on the viue for effecting better photosynthetic efficiency, should be aimed at for selecting potentially high yielders.Item Comparison of three methods of measurement of leaf area in soybean(Kerala Agricultural University, 1979) Geetha krishnan Nair, P; Vikraman Nair, R; Sukumaran Nair, PItem Estimation of leaf area in pineapple(Kerala Agricultural University, 1978) Balakrishnan, S; Sukumaran Nair, P; Nair, K K R; Nambiar, I P SItem Occurrence of localised partial earhead sterility in a rtce mutant(Kerala Agricultural University, 1969) Gopakumar, K; Sukumaran Nair, P
