    Soil and Leaf Analyses in Relation to the Nutrition of High Yielding Coconut Genotypes
    (1976) Kamala Devi, C.B.; Velayutham, M.; Haridasan, M.
    Seasonal changes in the nutrient composition of index- leaf and available nutrien status of a ten year old coconut planatation on acid sandy loam soil were evaluated in three high yielding coconut genotypes (West Coast Tall, Tall x Dwarf, and Dwarf x Tall) growing under three fertilizer levels. Seasonal changes in leaf nutrients status confirmed that the fourteenth leaf could be taken as the index leaf under the local conditions. Available K was a limiting nutrient which was reflected in deficient K concentration in leaf of control plots. An inverse relationship between K and Mg content of leaf was observed. Leaf concentration of N was not significantly influenced by fertilization. Even at the highest level of fertilizer application was below the critical limit proposed by IRHO. However, yield data indicated that the critical limit could possibly be lowered to suit the West Coast of India conditions. No significant variation was observed in P content of leaves due to fertilisers or genotypes. Fixation of P in the soil, appeared to be accentuated during monsoont months. NPK fertilization increased the concentrations of Mn, Zn, Fe, and Cu in the leaf while that of Ca, S, Fe, B, and Mo were unaffected.

    Soil Water Characteristic Curves And Hydraulic Conductivity Of Some Laterite And Red Sandy Loam Soils Of Kasaragod Area
    (1979) Haridasan, M.
    The soil water characteristic curves of three Iaterite profiles from Kasaragod, Muttathody and Sullia indicate that the amount of water that may be stored between 0.1 bar and 15 bars in these profiles is 4 to 8% by weight. The amount of water that can be stored in red sandy loam soils of Kasaragod between 0.1 bar and 15 bars is less than 4%. The hydraulic conductivity of the Iaterite soils ranged from 11.9 to 30.8 cm/h and that of red sandy loam soil from 40 to 114 cm/hr.
