Item Coconut breeding : A Comparative study of Tall x Dwarf, Tall x Gangabondam and tall x tall hybrid seedlings in the nursery for maximum expression of vigur(1964) Satyabalan, K.; George, M.V.; Radhakrishnan, V.Item Preliminary observations on the influence of pollen parent on copra content in coconuts (Cocos nucifera L.)(1963) Ninan, C.A.; Pankajakshan, A.S.; Radhakrishnan, V.Item Preliminary observations on the influence of pollen parent on copra content in coconuts (Cocos nucifera L.)(1963) Ninan, C.A.; Pankajakshan, A.S.; Radhakrishnan, V.Item Studies on Leaf Spiral in Coconut(1968-08) Satyabalan, K.; Krishna Marar, M.M.; Radhakrishnan, V.Studies on the leaf spiral in coconut have indicated that in a very large population of palms the occurrence of left-spiralled and right-spiralled palms may roughly be 50 : 50. Further studies made on a large number of palms have confirmed the previous findings that the direction of leaf spiral has no bearing on the yield of nuts and that there is no association between spiral character and other characters of economic significance like copra content per nut arid annual copra outturn in the palms of the local ‘Tall’ variety.Item Yield variation and its relationship with age and growth of under planted coconut palms(1972-05) Satyabalan, K.; Mathew, J.; Radhakrishnan, V.The tall variety (Var. typica) of the coconut palm, which lives even up to 80 or 90 years, is the one that is most extensively cultivated on a plantation scale in all the coconut tracts of the world. The age at which the palms come into bearing and their performance are highly variable and are dependent on the soil and climatic conditions and methods of management. In Kerala, the South-West Coast of India, since fresh area is not available for planting, new plantings taken up are all of underplanting nature with the result that the growth and performance of the seedlings under-planted are affected by the root and shade effects of the neighbouring palms. In this paper the results of a study made on the yield variation of under planted coconut palms of West Coast Tall variety, the time they had taken to attain their full bearing stage, the period taken to attain regularity in yield and the relationship of yield with the age and growth characters of the palms are presented and discussed.Item Yield Variation and its Relationship with Age and Growth of Underplanted Coconut Palms(1972) Satyabalan, K.; Mathew, J.; Radhakrishnan, V.
