Abstract

The pink discoloration in coconut water is a result of the initial enzymatic action of polyphenol oxidase (PPO) on the phenolic substrates which are naturally present in the product. Activity of the enzyme is further enhanced by metal contamination such as copper and exposure of the product to high temperature during its processing and storage. The optimum copper concentration to initiate pinking in coconut water was established at 3.96 x 10-04 mM. The PPO level was also shown to vary among coconut varieties and ages. When subjected to optimum conditions for enzymatic activity, the water from younger nuts (7-8 months old) went pink while mature nuts (9-10 months old) showed no discoloration. Application of food-grade resins to remove the phenolic substrates in coconut water was deemed as a possible solution to prevent the discoloration. Further testing in this area needs to be done.

Abstract

The production of handicrafts, wares and novelty items utilizing small and short pieces of coconut wood, fronds and shell is a highly feasible and viable option to derive income from coconut residues and other cellulosic materials found in coconut plantation. Handicrafts and novelty items from coconut fronds, wood and other residues are potential export commodities that can compete with other indigenous products because of their unique appearance and quality. Given the tremendous amount of readily available raw materials from coconut farms, a manufacturer is assured of a sustainable operation. Property tests conducted on coconut frond’s structure have shown its fitness to be used as alternative material to some light wood species. It has an average specific gravity (sg) value of 0.20 and mean volumetric shrinkage of 63%. Effectual use investigations of coconut fronds and coconut fruit residues on machining, treatment, gluing properties and finishing requirements are all satisfactory. With the use of a technique, “mix and match”, they can be skillfully combined with coconut wood to make good finished products. Skills, creativity and craftsmanship on the part of the people involved in the job were crucial aspects of the production. Some of the crafts and novelty items produced were; all-purpose trays, trophies, flower vases and candle holders, chairs, dividers, plant boxes, table and dresser to name a few. The production cost estimates was at minimum with about 50-60 percent cheaper than the traditional materials such as wood.

Abstract

The apparent objectives of the govemment intervention measures in the coconut industry are identified and ranked. The inadequacy of data prevents estimation of basic coefficients re­quired for the analysis. The partial equilibrium‑analysis based on “a prior' expectations shows that the opportunities available to im­prove the tenns of trade in desiccated coconut and edible copra exports justify government intervention in these two products in the foriu of export duties. There may also be some justification for expanding extension services and public investment on coco­nut researeh, which enables to realise the production objective of government. The implications of the study crucially depend on the assumptions and the partial equilibrium technique used.

Abstract

SCDP is a World Bank and Government of Indonesia fundect project managed by the Directorate General of Estates of the Mi­nistry of Agriculture. This project is responsbile for the planting of coconut hybrids as well as local talls, but mostly hybrids. Since 1981 to date, some 22,000 ha have already been planted to hybrids in 70 coconut working centers (CWC) widely scattered in 6 provinces such as Aceh, Lampung, South Sulawesi, Central Su­lawesi, North Sulawesi, and Maluku (Fig.1).

Abstract

The genetic improvement of coconut is clifficult and costly for numerous reasons of which the chief ones are re­lated to its biology the length of the unproductive phase and the interval between generations, the low multiplication rate and the lack of an asexual mode of reproduction, the size and weight of its seed and the absence of dormancy, the bulk of the tree and low planting density. In most coun­tries, the means provided to researchers were and still are very limited, partly perhaps because coconut has remained essentially a smallholding tree and the private plantation sec­tor has taken relatively little interest in it.

Abstract

Before 1939, Indonesia was the largest copra exporter in the world (FAO 1983). But since then until 1970 it was only the se­cond largest copra exporter after the Philippines (Heesch & Kuhl­mann 1982). Between 1970 and 1980 the exports of copra from Indonesia declined drastically from 184,000 tons in 1970 to only 36,000 tons in 1980, on average a decrease of about 37.6 per cent per annum for the period (Asnawi & Darwis 1984). Since 1983 Indonesia has had to stop exports of copra due to a deficit in na­tional coconut production relative to domestic needs. For example, in 1983 the total production of coconut in Indonesia was only about 2.4 million tons copra equivalent while the total consump­tion of coconut in the country in that year was about 2.48 million tons. Thus, there was a deficit in coconut production of about 80,000 tons copra equivalent in the country in that year (Asna­wi & Darwis 1984).

Abstract

A two-year nursery study of embryo-cultured Laguna Tall (ECLAGT) and embryo-cultured Makapuno Tall (ECMAKT) coconut seedlings was conducted at the Philippine Coconut Authority - Albay Research Center, Guinobatan, Albay aimed to know the effects of applying different levels of sodium chloride (NaCl) (common table salt) and chicken manure (CM) on the vegetative growth and leaf nutrient status of the seedlings. The soil used in the study is a volcanic ash- rich Guinobatan silt loam, classified as Entic Dystrandept soil subgroup (U.S. Soil Taxonomy/Classification). EC seedlings with the application of NaCl at a total dose of 18-54 g/seedling and chicken manure at 250-750 g/seedling, applied within the 12-month nursery (at intervals of 2,4,6,8,10 months) significantly produced taller seedlings with bigger girth and more total living fronds than the unfertilized ECLAGT and ECMAKT seedlings. The levels of nutrient application (fertilization) on EC seedlings is clearly much lower than that of the average rates used in growing ordinary seedlings from seednuts, i.e. seedling with embryo attached to the whole nut in the nursery. The better growth of ECLAGT and ECMAKT seedlings in terms of their girth, plant height and total living fronds produced was significantly associated with higher or very satisfactory levels of leaf N, P, K, Cl, Ca, Na, Mg, S, B, and Fe (leaf #4 of 12-month old EC seedlings). The overall results clearly indicate the practical need to apply a combination of sodium chloride and dried chicken manure, even at moderate rates (total) of 18 g/seedling and 250 g/seedling respectively, divided equally during the 12-month nursery stage for normal growth and proper nutrition of EC seedlings. This recommended fertilization management practice should ensure healthy and good quality ECMAKT seedlings as planting materials.

Abstract

Value addition to coconut oil is highly desirable in order to increase the range of coconut products. A study was conducted to formulate palatable coconut oil (CNO) blends enriched with essential fatty acid (EFA) using sesame seed as the supplementary source of EFA. For this purpose, micro-expelling process was employed to extract oil blends out of the dried coconut grating mixed with varying proportion of sesame seed (w/w; 0, 1, 2, 3, 4, 5, 7 and 10%). A sensory evaluation by a 30-member semi-trained panel was conducted using a seven-point hedonic scale in order to determine the critical limit of CNO fortification with sesame. Similarly, changes in fatty acid composition were determined using Gas Liquid Chromatography (GLC). Statistical analysis of the sensory data showed that a mild odor of sesame started to appear in the oil blends at 4% level of sesame mixed with dried coconut gratings. According to fatty acid methyl ester (FAME) analysis, the relative increase in linoleic acid was only marginal although there was a substantial increase in unsaturated fatty acid component. At 5% level of fortification, the increment in linoleic acid was 9.2%.

Abstract

Lace bug, Stephanitis typica (D) and the leaf eating caterpillar, Opisina arenosella W. are two common pests in the coconut ecosystem. Lace bug is the vector of root (wilt) disease of coconut as it harbours and transmits the pathogenic “phytoplasma”. Leaf eating caterpillar is an outbreak defoliator pest. During field collection of these insects, it was observed that in some samples there was green colour sporolation on the cadavers of these insects. From such specimens a fungus was isolated and purified. It was identified as Aspergillus and then confirmed as A. flavus Link. In the laboratory, this fungus was tested for pathogenecity on hosts by different methods of spore application. It was observed that 80% S. typica nymphs died within 3 days and 80-90% of the O. arenosella larvae were mycosed within 3-4 days. In this paper, we discuss the above aspects in detail.

Abstract

Sangicoccus sp. nr. truncatispinus (Reyne) (Eriococcidae: Homoptera) is recorded for the first time as a major pest of coconut palms in the Philippines. It is also the first record among the coconut growing areas in the world. It sucks the plant sap resulting to chlorosis of leaves. Furthermore, honeydew droplets exuded by the pest accumulated on upper leaf surfaces become substrate for sootymolds. The severe infestation observed in late 1980’s already spread to 6 out of 8 municipalities of the southern second district of Palawan. Presently, crop losses are estimated to reach 53% of the nut yield. The prevailing easterly and westerly wind directions of 1-5 m/sec coupled with the dense manner of planting enabled first instar nymphs (crawlers) to spread to other palms. The long dry spell also favored the proliferation of Sangicoccus sp.bv. Controlling the spread and outbreak of this pest seems to be difficult as it thrives on eleven alternate hosts. Ant attendance contributed to dispersal and protection from natural enemies. Moreover, field population of ten predatory species remained minimal. Possible strategies for its control are presented.
