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 S
