Item Albinism in Coconut Seedlings(1959-10-10) Pandalai, K.M.; Pillai, R.V.Item THE COCONUT PALM - A MONOGRAPH(1958) Menon, K.P.V.; Pandalai, K.M.Item Coconut wastes can find many industrial applications(1966-06) Pandalai, K.M.; Krishna Marar, M.M.Item Coir dust and river silt as fillers in the reclamation of marshy lands('Kaipad' lands)(1966-04) Sankaranarayanan; Balakrishnan Nambiar, C.K.; Pandalai, K.M.Item Disease incidence and yield of coconut in relation to foliar spiral(2007-02-08) Radha, K.; Pandalai, K.M.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 Feeding of plants through leave(1959-08) Pandalai, K.M.Item Fertlizer Placement -A Better Farming Procedure(1963-08) Pandalai, K.M.Item Home of the Coconut(1956) Gangolly, S.R.; Nambiar, M.C.; Pandalai, K.M.Item The Influence Of Some Agricultural Practices On The Enzyme Activity Of Coconut Water(1965-12) Nagarajan, M.; Pandalai, K.M.Item Investigations on Diseases of the Coconut Palm in Travancore - Cochin State -Studies on Soil Conditions in Relation to Disease Incidence(2007-02) Sankarasubramony, H.; Menon, K.P.V.; Pandalai, K.M.1. The coconut palm appears to thrive fairly well in all the three main soil types found in the Tra-vancore-Cochin State. 2. Disease appears in trees growing in all these soil types and the disease symptoms are uniformly thesame irrespective of the locality and nature of the soil type. 3. Compared to healthy areas the results of analysis of soil samples from diseased areas show a highly depleted condition in the major plant food factors particularly in the content of available potash. 4. The soils from diseased areas have a very low clay content and consequently a very low water holding capacity. 5. The base exchange properties of the soils from diseased areas, the composition of the clay fraction etc. reveal that the soils are of a very poor type from point of view of fertility. 6. Various factors which appear to be individually or collectively responsible for the disease incidence are discussed and future lines of work briefly indicated. 7. Additional evidence has been presented with regard to the importance of soil conditions in relation to disease incidence.Item The Manganese Content of Soil and Plant Tissue in Relation to the Root and Leaf Diseases of the Coconut Palm(1951) Sankarasubramony, H.; Pandalai, K.M.; Menon, K.P.V.Item The Manganese Content of Soil and Plant Tissue in Relation to the Root and Leaf Diseases of the Coconut Palm(2007-02) Sankarasubramony, H.; Menon, K.P.V.; Pandalai, K.M.Data is given on the manganese contents of tissues collected from healthy and diseased coconut trees and of soils of the respective areas. The manganese contents vary between very wide ranges,from traces up to 435 p.p.m. in soils and from traces to 176.5 p.p.m. in tissue samples. These make it difficult to diagnose the disease as involving a manganese factor and there appears to be no correlation between disease incidence and manganese status of the soils and tissues of the ,coconut palm. Work to elucidate the problem further is in progress in these laboratories.Item Mass Production of Coconut Hybrids Calls for Cautious Approach(1965-09) Pandalai, K.M.; Satyabalan, K.Item Nutrient Enrichment of the Coconut Soils of the Humid Kerala Coast through Monsoon Precipitations(1962-04) Vijayalakshmi, K.; Pandalai, K.M.Item Observations On The Sudden Wilting Of Coconut Palms At Thottapally Spill Way Area In Travancore-Cochin(1954) Pandalai, K.M.; Menon, K.P.V.; Sankarasubramony, H.1. The cause of the sudden wilting of coconut palms in the Thottapally Spillway area, where, peaty subsoil has been dredged out and dumped on to the bases of healthy palms has been investigated and described. 2. The wilting of the palms appears to be due to their desiccation and root injury as a result of the change in the soil conditions caused among other factors viz. (a) the high acidity of ths dredged subsoil and subsoil water. (fc) the presence in it of readily oxidisable agents such as sulphides, ferrous iron etc. (c) the presence in it of toxic agents such as soluble ferrous iron and soluble aluminium (J) potential capacity of the subsoil for the formation of free mineral acids by hydrolytic changes as well and (e) complete anaerobic condition in the root rhizosphere causing intense root suffocation. 3. The cause of the wilting has been shown to be purely a physiological factor.Item Observations on the Sudden Wilting of Coconut Palms at Thottapally Spill Way Area in Travancore-Cochin(2007-02) Pandalai, K.M.; Menon, K.P.V.; Sankarasubramony, H.1.

Certain disorders, causing a sort of chlorosis and necrosis of the foliage of coconut palms in Travancore-Cochin have been investigated by foliar analysis, for potassium,calcium, magnesium, phosphorous and nitrogen. 2. Statistical examination of the data of chiemical analysis of the leaflets from different fronds, From healthy trees as well as trees in diifferent stages of the disease, showed an accumulation of the nutrient factors in the leaves from diseased trees. 3. Different aspects concerning how far possible impaired physiological processes due to disease,or inadequate translocation from the. leaf to the other parts of the plant are responsible for the observed accumulation of nutrients in the diseased leaf tissue have been briefly discussed. 4. Further work from the point of view of plant physiological aspects is now in progress.Item On the potash content and enzymic activity of coconut water in relation to the nutrient need assessment of the coconut palm(1972-06) Pandalai, K.M.; Nagarajan, M.
