Item Alternative uses of arecanut(2007-02-08) Nayar, N.M.; Annamalai, S.J.K.Item Anthesis and anther dehiscence of cashew flower(2007-02-08) Mohan, K.V.J.; Kumaran, P.M.; Murthy, K.N.; Nayar, N.M.Round the clock observations on anthesis were made for five consecutive days in three periods of flowering viz., early December, mid-February, and late April. The peak period of anthesis of male flower was around 6 b and the same for bisexual flower was around 11 h. The time taken for anther to dehisce with respect to flowers opened at different hours starting from 6 h was recorded. The time required for dehiscence reduced linearly as the day advanced.Item Coconut research & development(2007-02-08) Nayar, N.M.Item Coconut research and development(2007-02-08) Nayar, N.M.Item Coconut research and development(1978) Nayar, N.M.Item Coconut research and development(CPCRI, 1983-08) Nayar, N.M.Item The coconut root (wilt) disease - A state of the art report(2007-02-08) Nayar, N.M.; Jayasankar, N.P.Item Conservation of Plantation Crops Genetic Resources(1983) Nayar, N.M.Item Conservation of plantation crops genetic resources(1983) Nayar, N.M.Item Diamond jubilee celebrations of coconut research in India: Recommendations(2007-02-08) Iyer, R.D.; Nayar, N.M.; Bavappa, K.V.A.Item Diamond jubilee celebrations of coconut research in India: Recommendations(1977-06) Iyer, R.D.; Nayar, N.M.; Bavappa, K.V.A.Item Distribution, morphology and ecology of Piper species in Karnataka, India(2007-02-08) Rahiman, B.A.; Murthy, K.N.; Nair, M.K.; Nayar, N.M.Collections of the genus Piper occurring widely in the forests of Karnataka, India were made. These consisted of eight species, P. nigrum Linn., P. longum Linn.,P. attenuatum Buch--Ham., P. galeatum C. DC, P. trichostachyon C. DC, P. argyrophyllum Miq., P. hymenophyllum Miq., and P. brachystachyum Wall. The various species showed considerable variation in distribution habitat preference, ecology, and morphology. All these Piper species were unisexual and dioecious, though the cultivated varieties of P. nigrum are bisexual. The two morphologically similar taxa, P. galeatum and P. trichostachyon, showed adjacent distiibution. The genus showed senescence in distribution.Item Glue adhesive properties of arecanut leaf sheath boards(2007-02) Annamalai, S.J.K.; Menon, S.R.K.; Nayar, N.M.3-ply arecanut leaf sheath boards were made at the laboratory with two veneers of arecanut leaf sheath and one veneer of wood under various combinations and with different glues namely starch glue (cold pressing), animal glue (cold pressing) poly vinyl acetate (Fevicol-Pidilite -cold pressing), Epoxy resin adhesive (Araldite-Ciba Geigy-cold processing) and urea formaldehyde (hot pressing). The boards were tested for their glue shear strength and water resistance in accordance with the IS specifications for tea-chest grade plywood. Areca sheath boards made with UF resin adhesive and wood veneer as core were found to have 50% more wet glue shear strength than the other areca sheath boards. Use of extenders like tamarind seed powder and deoiled sal meal up to 15 % to the UF resin adhesive and the type of wood used were found to have no adverse effect on the glue shear strength of the boards. Though the areca sheath boards satisfied only 50% of the IS requirements for tea chest grade plywood, they were found to have better wet glue shear strength over the locally purchased non-ISI grade tea chest plywood.Item Increasing Fruit Set in Cashew by Hormone Spraying(2007-02) Murthy, K.N.; Kumaran, P.M.; Nayar, N.M.A study was conducted to determine the effectiveness of seven of the most common plant hormones on fruit set in cashew and also to determine the optimum dosages for each and appropriate time for spraying. All the hormones were able to increase fruit set considerably but 2, 4-D, NAA, and IBA were the best, giving more than 50% fruit set over the control. It was difficult to determine the optimum time for spraying because of the long flowering phase of each panicle and the completely overlapping flowering in the large number of panicles produced in each tree. The study showed also that the beneficial effects of hormone spraying were seriously upset by severe incidence of inflorescence blight.Item International Cashew Symposium, 12-15 March, 1979, Cochin (Kerala, India): Summary Report and Recommendations(2007-02) Hameed Khan, H.; Bhaskara Rao, E.V.V.; Nayar, N.M.This first International Symposium on Cashew was organised jointly by the Indian Council of Agricultural Research, New Delhi, International Society of Horticultural Sciences, The Hague, and the Indian Society for Plantation Crops, Kasaragod. In addition to the Symposium, the following programmes were also arranged: an exhibition with accent on cashew entitled "CASHEW 79"; release of a 12 min long colour film Cashew, which was specially produced for the and occasion; four special slogan cancellations; release of two books "Cashew" and "Bibliography on Cashew". In addition, seven technical and agricultural journals had also brought out special numbers to mark the occasion. In the Symposium, 75 papers were presented, 49 orally and 26 as poster demonstrations, covering all aspects of cultivation, management, technology, and marketing. The highlight of the Symposium was a special discussion on vegetative prop?gation. In this, the work done so far in the various centres was reviewed and suitable recommendations were made for developing the work further. The other recommendations include: setting up of an international cashew germplasm collection centre; developing methodology for enhancement of root growth through growth regulators, rhizobial cultures, etc., developing meristum culture technique for large scale multiplication of elite trees; standardisation of sampling technique for soil and tissue analysis; identifying natural enemies of Helopeltis; studying the pest complex infesting the inflorescence; introducing small devices for processing cashew; studying the possibility of using CNSL for developing unconventional products like plant protection chemicals, drugs and food additives; and using aluminised paper for packing cashew to reduce the cost of cashew.Item Introduction(2018) Nayar, N.M.Item Kerala Coconut Replanting Project(2007-02) Nayar, N.M.; Prafulla K.
