Abstract

Today India stands at the third position as far as the world situation of coconut production is concerned. Coconut occupies 1.1. million hectares of land producing 6,887 million nuts in this country. In the southern part of the country viz. Kerala, Kamata­ka, Tamilnadu and Andhra Pradesh, coconut is a very good source of income and these states account for most of the production of coconut. In spite of the importance it has in India's economy, the productivity of the crop is low. Although many factors are res­ponsible for the poor yields, the most important of these are the diseases that attack these palms and affect their productivity. Among these diseases, a few are killers while others are slow and debilitating in nature. For some of them the cause is known while the aetiology of some others is still elusive. This review envisages in discussing some of the recent research trends in the major diseases of coconut in India.

Abstract

High cost of transport and the short storage fife of recalcitrant seednuts are two major obstacles to the effective field collection and exchange of coconut germplasm. An in vitro method invol­ving the culture of zygotic embryos of coconut was developed to overcome these problems. The excised embryos were initially subjected to a slow growth phase by culturing in an agar based medium containing nutrients barely sufficient for their survival. After 2, 3 and 5 months in this medium, the embryos were trans­ferred to the gerinination or the development medium for resumption of growth and plant development. 53% of the zygotic embryos preserved in this manner for a period of 2 months produced nor­mal plants when transferred to the gennination medium. The percentage germination dropped to 32 after 5 months storage in the survival medium. The prolonged low temperature storage of cultures (100 and 40C for three months), caused irreversible damage to the coconut embryos and no plants were formed when transferred to the germination medium. The advantages of the technique are that a large number of 'seednuts' can be transported free of pests in a small container and requires no change in the culture medium during the preser­vation period. Unlike the germination medium, the survival me­dium is agar based and hence the risk of containination is low. The non gerridnators can be identified and rejected prior to the germination phase.

Abstract

Study of the variations in the yield of coconuts in the West Coast of India, in relation to the pattern of rainfall and duration of dryspell revealed that the yield obtained in any year is not directly related with the total rainfall received in the same year or in the preceeding years. Summer rains were having positive correlation with the yield in the succeeding year. About 60% of the variations in the annual yield were due to the changes in the duration of dryspell in the preceeding two years.

Abstract

Coconut stem has been utilized in every coconut producing country in some form or other. Its utiliza­tion varies widely from small bridges to houses, furnitures and works of art. In Indonesia it is used mainly in Java, the most densely populated island. In other islands it is rarely used except for foot bridges because of two reasons. First, the farmers are reluctant to fell their coconut trees for its yield, however, small it is. Second, there is still enough supply of forest wood.

Abstract

In the plantation agriculture in Sri Lanka, coconut occupies the highest area of nearly 420,000 ha. It is distributed in all 24 districts. The estate sector (8 ha or more) comprises 104,000 ha (24.7%) of the area while the balance, 316,000 ha (75.3%) is categorized as small holdings

Abstract

Tapered roof shingles from coconut wood were fabricated and treated separately with four preservatives, namely: copper‑chromearsenate, pentachlorophenol, copper sulfate and copper sulfate + potassium dichromate. Untreated and treated shingles were installed side in roof framed structures and exposed outdoor in the FPRDI "graveyard" area for weather and durability tests. Fabrication, treatment and installation costs of shingles were evaluated. Performance ratings on the different degradations such as splitting/checking and twisting of shingles, retention of original colour/appearance, and protection from weathering and fungal infection in relation to thickness, nailing patterns and treatments of coconut wood roof shingles after 11 months of weather exposure tests were evaluated and statistically analysed. Cost comparison between coconut wood roof shingles and G.I. corrugated sheet gauge #26 are also presented in this report.

Abstract

An investigation was made to determine the relative performance of some chemicals against growth of blue stain fungus and attack of pinhole borer on freshly‑sawn coconut timber during the drying process. The fungicides used were Farmay Plus, Azaconazole and the standard chemical combination of Sodium Pentachlorophenate, BHC and Borax Pentahydrate. Cislin, an insecticide, was mixed with either Farmay Plus or Azaconazole solution. Results after 12 weeks of air drying showed that all fungicides failed to give the desired protection against blue staining. Performance ratings of planed wood samples were within the range of heavy to severe stain infection. Although none of the fungicides was able to effectively control the blue stain fungus, their respective performance have been to some extent ascertained. On the other hand, Cislin showed an acceptable level of protection from pinhole borer infestation on coconut lumber.

Abstract

An investigation was made to determine the relative performance of three readily available inorganic chemicals containing either copper or chromium when applied singly or in combination to sawn coconut timber surfaces. The treating solutions, consisting of chromic acid (H2CrO4) sodium chromate (Na2CrO4) and copper sulphate (CuSO4), were applied by trush to wood surfaces with one coating at the rate of approximately 155 grams per square meter. The specimens were exposed outdoors on racks inclined at 450 angle and facing south. Results after 3 years of test showed that treatments with mixture of H2CrO4 and CuSO4 or combination of Na2CrO4 and CO4 performed better than single application of either H2Cr4 or Na2CrO4. The former treatments still showed uniform and pleasing appearance after the exposure period.

Abstract

A programme of experimentation and training on the production of charcoal from coconut stems in transportable metal k.ilns was carried out. Comparisons were made between different timber densities, preparation methods and kiln loading systems. Other timber sources and traditional kilns were used. The highest density coconut wood produced the best charcoal and extensive preparation was found to be necessary. Local clay kilns produced excellent charcoal, but were slow and needed considerable fuel. Coconut stem charcoal. production was markedly different from carbonisation of wood from dicotyledonous trees. The charcoal produced was found to have similar calorific value to that from other woods, but was faster‑burning and easier to ignite. Content of volatile matter was low and little ash was produced. The charcoal was often rather wet. A sample of consurners found that the charcoal was better than they had expected. The main complaint was the speed of burning.
