    Seedling progeny analysis in coconut types
    (Kerala Agricultural University, 1995) Manju, P; Gopimony, R; Nampoothiri, K U K; Saraswathy, P
    The study was undertaken to identity prepotent palms from among five coconut types vi/.., three Komadan generations. West Coast Tall and Natural Cross Dwarf based on growth rate of seedlings at the 9th month of germination. For most of the seedling characters, Komadan generations (Manju, 1992) showed significant superiority over WCT and they behaved as a distinct group with regard to total leaf area over both WCT and NCD. They were also found to be significantly superior to WCT for seedling vigour index and number of seedlings with split leaves. The three Komadan generations were on par regarding recovery ot quality seedlings and were significantly superior to WCT. Based on this character, 20 per cent of the palms in Komadan were identified to be prepotent.

    Irrigation management on yield stabilization and annual productivity of coconut
    (Kerala Agricultural University, 1996) Jose Mathew; Piilai, G R; Santhakumari, G; Kuruvilla Varughese
    The impact of irrigation water management, with the treatments linked to climatic parameters, in coconut on inter-harvest yield variation and annual productivity was studied in a five-year field experiment.Yields got stabilized with adequate irrigation showing minimum fluctuation among harvests during different periods of the year.The data on per cent contribution of individual harvests, standard deviation, yield range between harvests and coefficient of variation clearly supported this argument. Based on yield trends and irrigation water consumption, irrigation at 50 mm CPE with 50 mm water was suggested as the best schedule for irrigating coconut during dry spell.

    Varietal preference, growth and development of pests necrobia Rufipes de geer and oryzaephilus surinamensis linn, in stored copra
    (Kerala Agricultural University, 1998) Nalinakumari, T; Mammen, K V
    Copra is subjected to the attack of various insect pests during storage. Necrobia rufipes De Geer and Oryzaephilus surinamensis Linn, were found to be the most important. The varieties / cultivars tested were Chavakkad Dwarf Orange x West Coast Tall, Laccadive Micro, Gangaboridam, West Coast Tall x Chavakkad Dwarf Orange, Chavakkad Dwarf Orange, West Coast Tall, Laccadive Ordinary, West Coast Tall x Chavakkad Dwarf Green and Chavakkad Dwarf Green. Data on larval period, larval mortality, Chavakkad Dwarf Green. Data on larval period, larval mortality, pupal period, pupal mortality, percentage of adult emergence, adult longevity and the fecundity of the beetles and incubation period of the eggs were recorded daily after releasing one day old larvae of the insects in these varieties. The growth index of the insects in each treatment was calculated by dividing the percentage of adult emerged with the mean number of days for adult formation. Studies conducted revealed that the severity of infestation varied with varieties and the growth index varied with respect to larval period, larval mortality, pupal period, pupal mortality, adult emergence, adult longevity and fecundity. In overall assessment of the study, CDO x WCT, LM and LO were identified as less desirable for keeping the population build up low, while CDG and WCT x CDG were better and the remaining varieties were found to be intermediate.

    Genetic variability in nine cultivars of coconut (Cocos nucifera L.)
    (Kerala Agricultural University, 2000) Sindhumole, P; Ibrahim, K K
    An experiment conducted at the Instructional Farm, College of Horticulture, Vellanikkara, Thrissur on nine coconut cultivars during 1995-96 in RED with three replications and three palms per plot revealed the absence of significant variation among most of the characters. Economic characters showed higher genotypic coefficients of variation (16 to 22 %) compared to vegetative and reproductive characters. Among all the characters, hcritability was maximum for petiole length (52 %) followed by the economic characters, per cent oil content and nut yield (45% each).
