CORD https://journal.coconutcommunity.org/index.php/journalicc <p>Cord is a semi-annual Journal of the International Coconut Community (ICC) devoted to coconut research and development (R &amp; D). The ICC is the first commodity based organization established under the auspices of United Nations-Economic and Social Commission for Asia and the Pacific (UN-ESCAP) in 1969. It is an independent intergovernmental organization, currently consisting of nineteen member countries, namely: Federated States of Micronesia, Fiji, India, Indonesia, Jamaica, Kenya, Kiribati, Malaysia, Marshall Islands, Papua New Guinea, Philippines, Samoa, Solomon Islands, Sri Lanka, Thailand, Timor Leste, Tonga, Vanuatu, and Vietnam. The objectives of the ICC are to promote, coordinate and harmonize all activities of the coconut industry to achieve the maximum socio-economic development of the industry. In addition to Cord, the ICC publishes The Cocommunity (monthly newsletter), Coconut Statistical Yearbook (yearly) and Cocoinfo International (semi-annual popular Journal on the coconut industry) and other ad-hoc publications. Cord welcomes original research articles on any aspect of the coconut industry. The views expressed in Cord do not necessarily represent those of the editors or the ICC. Although the editors are responsible for the selection and acceptance of articles, the responsibility for the opinions expressed and for the accuracy of statements rests with the authors.</p> en-US jelfina@coconutcommunity.org (Dr. Jelfina C.

If it spreads to the major coconut growing area, it might severely damage the coconut industry in Sri Lanka. Government commenced a disease control program to eradicate the disease and, more importantly to prevent spreading of the disease to major coconut growing areas. The major constraint in this program is the lack of an accurate and reliable method for identifying affected palms. Visual symptoms are used to identify the affected palms for removal, yet growers are not always convinced of the method of resisting palm removal. This poses a serious threat to the implementation of the disease control program. Although a Nested-PCR-based disease diagnosis was established earlier, the detection rate and reliability need further improvements. Therefore, an urgent necessity for a more reliable disease detection method has arisen. In the current study, a Real-Time Polymerase Chain Reaction (qPCR) powered by a pair of primers and a probe designed from the published partial sequences of the WCLWD phytoplasma was validated with 202 coconut samples and a detection rate of above 95% was achieved. This newly established detection system was highly reliable and a way forward for controlling the WCLWD disease in Sri Lanka.</p> H.T.R. Wijesekara, S.A.C.N. Perera, D. Bandupriya, M.K.

However, similar to the other agricultural industries, coconut has confronted by fluctuation in prices and accords the importance of reliable price modelling and forecasting techniques to ease the burden on the value chain actors. Therefore, the objective of this paper is to review the main approaches used in modelling and forecasting coconut prices, with an assessment of the strengths and weaknesses of each approach. The modelling techniques used in coconut price forecasting were mainly time series models dominated by univariate time series models. This type of models excessively confines the analysis to a single variable, despite the many interactions affected in a system of coconut pricing. The major drawback in existing price modelling studies is the absence of interacting factors such as prices, production, climatic variables and their interactions as a system. Therefore, it is important to extend the existing studies of coconut price modelling and forecasting with a system’s approach by including other influencing variables to generate more realistic forecast values, allowing the industry to adopt its changing circumstances.</p> <p>Keywords: Coconut, modelling, price forecasting, time series models, system’s approach</p> M.

This dryer was designed to provide farmers an alternative to traditional and existing dryers particularly the semi-direct and indirect dryers. The components of the dryer were drying bed, plenum chamber, tunnel and firing chamber. It has a capacity of 2,000 nuts and the husks from the nuts were used as fuel for the dryer. The means of the average drying temperature on the front, middle and rear portions of the drying platform were 56.5 <sup>o</sup>C, 58.2 <sup>o</sup>C, and 58.4 <sup>o</sup>C, respectively. The average time of drying in bringing down the moisture content of the copra from 50% to 12% wet basis was 24 hours using only 66.30% of the husks. As of January 2017, the total cost of the dryer with shed was P 61,100.00 and the computed break-even cost was P 1.82/kg. The performance of the dryer is comparable to the existing dryers.</p> Mencius Lesidan Copyright (c) 2020 CORD https://journal.coconutcommunity.org/index.php/journalicc/article/view/419 Sat, 21 Nov 2020 17:30:44 +0000
