It was observed that trailing the vines on dead wood posts to a vertical height of ;• and then trailing them horizontally on wooden trellies was better than trailing the vines on Plumeria standards to a height of A' and then trailing or looping horizontally on wooden trellies.Item Note on germinating seeds of pineapple (Ananas comosus merr.)(Kerala Agricultural University, 1976) Gopimony, R; Balakrishnan, S; Kannan, KItem Herbicidal control of weeds in pineapple variety kew(Kerala Agricultural University, 1976) Balakrishnan, S; Pillai, G R; Kannan, K; Gopalakrishnan, RA herbicidal trial on pineapple variety 'Kew' was undertaken at the Pineapple Research Centre, Kerala Agricultural University Vellanikkara during the years 1974-76 to test the efficacy of diuron and bromacil at different doses- The herbicides in general effectively controlled a broad spectrum of weeds. Among different dosages tried, diuron 3 kg per hectare was more effective and the treatment gave significantly increased yield without producing any harmful effects to fruit quality. From the point of economics also, diuron 3 kg per hectare was more economical.Item Pollination studies in pineapple varieties(Kerala Agricultural University, 1976) Gopimony, R; Balakrishnan, S; Kannan, K; Gopalakrishnan, Rstudy was undertaken using four varieties of pineapple to find out the time of anther debiscence and flower opening, time interval between various stages of flower development and best time of hand pollination for maximum seed production, i !u- time of flower opening and anther dehiscence in 'Kew* pineapple was found to be between 4 . 1 5 am and S a m The time interval between various stages of flower development was studied and found to be much shorter than those observed under Hawaii conditions. The results from the pollination trialshave shown that hand pollination in 'K.ew' variety of pineapple using pollen from three other compatible varieties can be successfully done at any time between 4.15 and 10.45 am.Item Control of banana rhizome weevil (Cosmopolites Sordidus Germ) and banana aphid (Pentalonia Nigronervosa) (coq.) by the use of granular systemic insecticide(Kerala Agricultural University, 1977) Nair, K K R; Joseph, D; Balakrishnan, SItem Response of nendran banana to different levels of N, P and K(Kerala Agricultural University, 1977) Pillai, G R; Balakrishnan, S; Veeraraghavan, P G; Santhakumari, G; Gopalakrishnan, RExperiments were conducted to study the response of nendran banana to different levels of N, P and K at the Banana & Pineapple Research Station, Kannara for five consecutive seasons from 1963 — 64. The results revealed that the nutrients N and K exerted a significant positive influence on fruit number and bunch weight. The optimum dose of N and K2O corresponding to maximum yield of fruit has been worked out as 191, and 301 g per plant respectively. The economic optimum dose according to to the prevailing market rate has been worked out as 133 and 260 g of N and KSO respectively per plant per year.
