Lunuwila, 1986) Liyanage, M.De.S.; Tejwani, K.G.; Nair, P.K.R.Item Nutrient content of some locally available organic materials and their potential as alternative sources of nutrients for coconut(CRI. Lunuwila, 2003) Tennakoon, N.A.; Bandara, S.D.H.Item Effect of monocrotophos on the leaf eating Caterpillar opisina arenosella walk , when injected into the trunk of the coconut palm(CRI. Lunuwila, 1985) Kanagaratnam, P.; Pinto, J.L.J.G.Item Irrigation in small holder coconut cultivation in Kerala , India - a financial analysis(Coconut Research Institute. Lunuwila, 1998/1999) Bastine, C.L.; Palanisami, K.Financial analysis of irrigation investments in existing as well as new plantations of coconut was conducted. The annualized capital costs and variable costs were included in the cost of irrigation. The levelised annual cost approach was used to compute the pumping cost. The study was conducted in a mixed cropping system. The effective area under each crop was computed and the allocation of irrgation costs was done accordingly. In all the land types the investments in irrigation was found to be highly feasible financially. The financial ratios were found to be higher in midland categories indicating that compated to the other regions, the midland region had higher potential for investment in irrigation.Item Alternative methods to determine plot sizes for tree crops. a case study from coconut data(Coconut Research Institute of Sri Lanka. Lunuwila, 1997) Peiris, T.S.G.; Thattil, R.O.Two methodologies are pooposed to determine the most efficient plot size for tree crops using data from experiments based on randomized complete block designs. Both methods can be generalized for data from any balanced design. The merits and demerits of these methods are discussed. The methods are illustrated using the data sets of long-term field ecperiments at the Coconut Research Institute, Sri Lanka. The results show that efficient plot size in field experiments for coconut for a wide range of agroecological regions is four or six palms.
