Item Marketing of coconut - a case study of Adat farmers service cooperative bank ltd, Thrissur(Department of Cooperation, Gandhigram, 1998) Veerakumaran, G; Philip, SabuItem Mother palm and seedling selection in coconut(Kerala Agricultural University, 1979) Kannan, K; Narayanan Nambiar, P KStudies were undertaken at the Coconut Research Station, Pilicode to find out influence of mother palm and seedling selection on the performance of the progenies. Palms yielding more than 80 nuts per annum and palms selected at random (bulk mother palms) are found to produce high yielding progenies. Palms giving an yield of less than 20 nuts are defenitely unsuitable for seednut selection. Seedling selection though necessary need not be as stringent as is advocated at present since the yield difference between vigorous and intermediate seedlings is not significant. However, for ensuring better establishment, early flowering and higher yield, poor seedlings should be rejected.Item Use of chilean natural potassium nitrate for manuring coconut(Kerala Agricultural University, 1975) Ramanandan, P LItem Studies on the open pollinated progenies of tall X dwarf coconut hybrids(Kerala Agricultural University, 1976) Kannan, KA study of the performance of the open pollinated progenies of T x D palms was conducted at the Coconut Research Station, Pilicode. Considerable reduction in the expression of hybrid vigour was observed from the iiisi generation T x D to the second generation open pollinated progenies. In respect of age at first flowering growth rate and leaf production they were more equal to the West Coast Tall than to T x D. About half the population gave higher yield of nut and copra than the parents while the other half was low yielders. A few of the parent palms produced high percentage of high yielders which may be due to prepotency.Item Study of the knowledge and attitude of farmers towards selected pest control measures for coconut(Kerala Agricultural University, 1977) George, T GRhinoceros beetle and red palm weevil were known to all respondents. Only 65,7 per cent were aware of the recommendations for pest control^ made fay the Government. Attitude of the farmers towards the ten statements were favourable. However, the intensity of the attitude varied from statement to statement. Attitude towards some statements like "It is possible to increase the number of nuts if control measures are adopted", "Every farmer must control pests for getting higher yield of coconut", was more favourable whereas statement like "The use of insecticides repeatedly upset balance of life in nature" was less favoured.Item Relationship between yield of coconut and rainfall pattern in the back-water region of Kerala(Kerala Agricultural University, 1978) Mathai, G; Panicker, K SItem Toxicity of newer insecticides to the coconut caterpillar Nephantis Serinopa Meyr and its parasite Bracon Brevicornis Wesmeal(Kerala Agricultural University, 1978) Kunjamma P Mathew; Nair, M R G K; Abraham, C CThe LD 50 levels of toxicity of phosalone, endosulfan, malathion, quinalphos, fenthion, phosphamidon. monocrotophos, fenitrothion, dichlorvos, BHC and carbaryl to 4th instar larvae of the coconut caterpillar Nephantis seringa were 0.02428, 0,02925, 0.05288, 0.05614, 0.08416, 0.09477, 0.09833, 01013, 0.1639, 0.2920and 0.4990 respectrvely. Toxicity of residues of dichlorvos 0.05%, fenitrothion, 0.05%, malathion 0.05% on coconut leaves to 1st instar larvae of N. serhwpa had become negligible on the 8th day of their application and that of residues of quinaiphos 0.05%, phoslone 0.05% and BHC 0.2% on the 16th day of application; residues of carbaryl 0.2%, and monocrotophos 0.02% showed toxicity beyond 16 days. Toxicity of residues of the same concentrations of dichlorvos, fenitrothion, fenthion, endosulfan and phosphamidon on coconut leaves to adults of Bracon brevicomis had become negligible in 8 days of application and that of residues of malathion, quinaiphos, phosalone and BHC in 16 days of application; residues of monocrotophos and crabaryl remained toxic to parasites beyond 16 days.Item Varietal reaction to coconut stem bleeding disease(Kerala Agricultural University, 1980) Radhakrishnan, T C; Neelakantan Potti, NItem Quality of copra and oil of coconut as influenced by sodium chloride nutrition(Kerala Agricultural University, 1987) Prema, D; Jose, A I; Narayanan Nambiar, P KItem Biology of myllocerus curvicornis (F), a pest of coconut(Kerala Agricultural University, 1984) Ponnamma, K N; Chandy Kurian; Abraham, V AMyllocerus curvicornis (F.) is a peston the foliage of coconut palm. The life history is completed within a period of 45 days. It has four larval instars and one pupal instar. The description of various stages, life history and habits are presented in this paper.
