Item Effect of manuring and intercultivation on the yield of coconut in relation to leaf rot and root (wilt) diseases(2007-02-08) Sahasranaman, K.N.; Radha, K.; Pandalai, K.M.The effect of (1) manuring with standard dose of NPK fertilizers at the rate of 0.55 lb. N, 0.56 1b. P2O5 and 1.0 Ib. K2O plus intercultivation, (2) heavy dose of NPK fertilizers 1.5 and 3.0 Ib. of N and P2OB, and 3.0, 4.5 and 6.0 lb. of K2O plus intercultivation and (3) no manuring and no cultivation, on the yield and foliar disease symptoms of four groups of palms affected by root (wilt) disease as well as leaf rot have been recorded. Manuring with standard dose of fertilizers plus intercultivation was found to be beneficial in maintaining an economic yield and the general health of the palms, although it has not been able to check the progress of the disease to any appreciable extent in the case of trees in an advanced stage of either of the diseases. A higher dose than the standard dose of manures is not advocated as it seemed, under the conditions of the experiment, to aggravate disease conditions and reduce yield. This probably arises due to the antagonists action of increased potassium on the magnesium.Item Effect of manuring and intercultivation on the yield of coconut in relation to leaf rot and root (wilt) diseases(2007) Sahasranaman, K.N.; Radha, K.; Pandalai, K.M.Item Insecticidal control of rhinoceros beetle helps to Increase yield of coconuts(1966) Sahasranaman, K.N.; Chandy Kurian; Lal, S.B.Item Insecticidal control of rhinoceros beetle helps to Increase yield of coconuts(1966) Sahasranaman, K.N.; Chandy Kurian; Lal, S.B.Item Mixed farming in coconut garden(2007-02) Sahasranaman, K.N.; Pillai, N.G.Item Mixed Farming in Coconut Gardens(2007-02) Sahasranaman, K.N.Item Mixed Farming in Coconut Gardens(2007-02) Sahasranaman, K.N.; Pillai, N.G.Item Mixed Farming in Coconut Gardens : Economics and its Effect on Root (wilt) Disease(2007-02) Sahasranaman, K.N.; Pillai, N.G.; Jayasankar, N.P.; Potti, V.P.; Thomas Varkey; Kamalakshi Amma, P.G.; Radha, K.A mixed farming programme, consisting of cultivation of fodder grasses and legumes in the interspaces of coconut, maintaining milch cows, and recycling of cattle wastes, is in progress at the Institutes at Kasaragod and Kayangulam. Increase in nut yield, improvement of soil nutrient status, and increased activity of beneficial microorganisms were observed in the experimental plots. At Kayangulam, where the palms are affected by root (wilt) disease, foliar yellowing was reduced but the treatment had no effect on the other symptoms like flaccidity and leaf necrosis. An evaluation of the economics of the practices, taking into account alt the inputs and income from coconut and milk, showed that mixed farming could increase per hectare income considerably. Employment potential also increased several fold due to introduction of this system in coconut gardens.Item Mixed Farming in Coconut Gardens Root (Wilt) Affected Tract(1979) Ramakrishnan Nayar, T.V.; Sahasranaman, K.N.Item Mixed Farming in Coconut Gardens Root (Wilt) Affected Tract(2007-02) Ramakrishnan Nayar, T.V.; Sahasranaman, K.N.Item A note on the yield of coconut in relation to rainfall and leaf rot and root (wilt) diseases(1962) Radha, K.; Sahasranaman, K.N.; Menon, K.P.V.Item Performance of four Fodder Crops in Coconut Garden Under Rainfed and Irrigated Conditions(2007-02) Ramakrishnan Nayar, T.V.; Sahasranaman, K.N.A field experiment was conducted at Central Plantation Crops Research Institute, Regional Station, Kayangulam, during 1975-77 to comp-pare the performance of four fodder crops—two genotypes of hybrid Napier, viz. Pusa Giant and NB 21, Guinea grass (Maekuenii) and legume Stylosanthes gracilis, in coconut gardens under rainfed as well as under irrigated conditions. The graminaceous fodders Pusa Giant, NB 21 and Guinea grass were on a par in herbage yield but gave significantly higher yield than the legume Stylosanthes, both under rainfed and irrigated conditions. The increase in yield of green fodder due to irrigation was highest in the case of NB 21 (55%) followed by Pusa Giant (44%). Under rainfed conditions and during dry season highest green fodder yields were obtained from Guinea grass.
