Root (wilt) is a major disease of coconut in Kerala and in certain parts of Tamil Nadu. The lasting solution for combating the disease is by evolving root (wilt) disease resistant/tolerant varieties through sustained breeding programmes. Development of visual symptoms of root (wilt) disease is very slow and there is a time lag between infection and symptom expression. Therefore, identification of root (wilt) disease-free palms using early diagnostic techniques (serological techniques) is a basic requirement for the production of quality seedlings. For the mass screening of coconut samples DAC-indirect ELISA has been standardized earlier using antibody raised against pathogen related protein found in diseased palms, but it take about 44 hrs for the completion of the test. In the present investigation using phytoplasma-specific antibodies, test could be refined to make it a more rapid and sensitive one. It has been found that the results could be obtained within 24 hrs with very high sensitivity of 98.4%. Similarly, efficiency of extracting antigen from coconut leaf samples was enhanced by using ART MICCRA D-8 tissue homogeniser. Highest difference in absorbance values between healthy and infected samples was obtained while using carbonate bicarbonate buffer pH 9.6 with additives followed by plain buffer. Thus test could be used to detect phytoplasmal infection in coconut palms even before the appearance of visual symptoms. The modified procedure is being used for identifying disease-free mother palms from disease endemic areas for producing quality seedlings either by crossing programmes or from open pollinated nuts.

Promotion of greater access to affordable choice of technologies and their prompt use for coconut productivity is necessary to sustainable development of coconut farming. The crux of the issue is; coconut growers who are aware and have the knowledge of the technologies, also seem to be reticent about adopting the package. The question therefore is; why does this happen? This research paper summons the identification of social and ecological elements that surround adoption of innovative technologies in improving coconut production and the kind of strategies for a best fit for a need-based programme of knowledge transfer, facilitating picking up a few technologies for possible adoption. A methodological prime-mover viz., Participatory Rural Appraisal, Planning and Action among coconut growers was used to walk the ‘reality-led’ and ‘technology-driven’ choices that are really acceptable and usable. Yet the farmers/neighbours appeared to be reluctant even to “talk” the “walk”. On the other hand, absence of dependable and sustainable model, lack of confidence, inadequate infrastructure and support systems, including sufficient and timely credit and constant exposure through IT seem to accelerate ‘vagaries’ on coconut for sustainable adoption. The need must, therefore be to polarize the two contrasting positions-appropriate tech-choice vs vagaries of adoption-by a suitable ‘model’ that would serve as a guide to coconut farmers.

Studies on the presence and involvement of proteases in the development and maturation of endosperm of Cocos nucifera L. revealed changes in concentration of proteases with the age of the nut, variety and season. More BAPNA (Na - Benzoyl DL - arginine p-nitroanilide) hydrolysing activity. Was observed at the immature stage and more gelatinolytic activity at the mature stage of the coconut endosperm development. There was apparent difference between seasons, the highest protease activity was during winter months.

The Tropical Development and Research Institute (TDRI) was formed on l April 1983 by the amalgamation of the Tropical Products Institute (TPI) and the Centre for Overseas Pest Research (COPR). The Institute has a long history of providing assistance and advice to developing countries in post‑harvest aspects of food and other agricultural commodities, which include the many products dexived from the coconut. This review covers the Institute's work over the last ten years and illustrates the wide range of interests concerning coconuts. These cover research and development on dehusking and processing projects, economic studies for the establishment of new coconut‑based industries, and technological improvements for the manufacture of charcoal from coconut shell.

The management practices recommended to increase coconut production in smallholdings are largely based on a seed‑fertilizeragrocide technology. The goal is to maximise production. HigI yielding varieties that need high inputs and management lavel, have been introduced. Application of chemical fertilizers pesticides and weedicides are advocated. The smallholders with limited funds at their disposal and faced with other constraints are unable to purchase the inputs. Thus an inappropriate technology is being passed on to them.

In the context of the fast reducing land‑to‑man ratio in the tropics, cropping systems which can integrate a variety of highly productive plant species and animals with human beings will have to be developed. Coconut having many favourable attributes is ideally suited for homestead farming under diverse situations. Its response to good management particularly fertilizer application and irrigation is indeed very good. Yield increases of the order of 84% due to manuring and 216% due to manuring and irrigation have been obtained in the native West Coast Tall. In coconut hybrids not only Wgher yields have been realised but better utilisation efficiency of native and applied nutrients observed, making them highly suited for improving the economic viability of small holdings. The potential that coconut offers for mixed cropping with a variety of crops, and mixed farming is very high. High density cropping in coconut plantations is also feasible. The cost benefit of some of the coconut based cropping systems have been presented, and the low productivity of coconut observed in majority of the coconut growing countries discussed keeping in view the remedial. measures that can be thought of for the existing maladies.

The importance of coconut stems primarily from its being an export crop. Coconut largely constitutes a crop of convenience in the basically agricultural, mainly subsistence, essentially rural-based economy of Fiji. It provides a basic dietary component and a source of cash income to meet social responsibilities, and employment opportunities in the various areas in which it is grown. Indeed, after sugar, coconut oil is Fiji's second most important agricultural export.

Major developments, have taken place in computer technology in the last decade and the rate of change is increasing. Reductions in the size and cost of microcomputers and the availability of vastly improved software can have, a beneficial impact on the speed with which agricultural research is analysed and its imphcations assessed. Examples of software of particular interest to agricultural economists dealing with coconut fanning systems are discussed in the paper.

The coconut industry is under pressure from low world oil‑seed prices and the increased availability of palm kernels. This paper reviews market conditions in the lauric sub‑sector, describes the marketing channels for copra and coconut oil, and sets out details of significant issues for the future. It concludes that the industry must take urgent steps to (a) improve the flow of market information, (b) develop cost saving means of production which lead to a range of items, and (c) investigate new markets for non-traditional products.
