    Comparative physiological studies on the drought tolerance of three hybrids of coconut
    (2007-02-08) Shivashankar, S.; George, K.M.; Rajagopal, V.; Voleti, S.R.
    Drought tolerance of three hybrid crosses developed at CPCRI, Kasaragod were compared using physiological and morphological indices. Leaf water potential, stomatal resistance and specific leaf weight measured during stress and pre-stress periods indicated that MYD x WCT possessed better ability to conserve moisture. Morphological parameters also gave similar results. Based on the data, the three hybrids could be ranked for drought tolerance in the order, MYD x WCT > MOD x WCT > COD x WCT

    Effect of long term coconut-grass system on certain nutrients in the soil
    (2007-02-08) Biddappa, C.C.; Bopaiah, M.G.; Kailasam, C.; Shanavas, M.; George, K.M.
    Nutrient profile, balance and input-output of nutrients over three block periods in an existing coconut fodder system under high rainfall condition of Kasaragod have been computed. Coconut-grass system enriched over control plot in organic carbon, nitrogen, manganese and copper in the surface soil while the nutrients in lower profile was low. While these elements were of net gain in the system over control, potassium, calqum, phosphorus and magnesium were on net loss. Over a period of fourteen years, guinea grass legume mixture gained NPK over other grass treatments. The input-output balance for the control plot (without grass) was negative for all the nutrients studied except phosphorus and potassium.

    Seedling Characters Related To Precocity Of Flowering And Early Yield In Coconut Hybrids
    (1993) Shivashankar, S.; George, K.M.
    An experimental trial to compare the growth and yield performance of three coconut hybrids was established during 1985. Preliminary results suggest that Malayan Yellow Dwarf x West Coast Tall (MYDXWCT) is the most precocious and has the highest yield, with the Malayan Orange Dwarf x West Coast Tall (MODxWCT) and Chowghat Orange Dwarf x West Coast Tall (CODxWCT) hybrids ranking second and third respectively. MYDxWCT is also relatively more tolerant to drought. The results establish the close relationship between seedling characters and the yield of young palms during the first two years of bearing indicating the potential of utilizing seedling growth data to predict the future yield performance of coconut hybrids.
