Abstract

Conventional chemical bleaching of coir generates a considerable amount of effluent which is discharged into the local water bodies thereby affecting the water quality there. The possibility of bio-bleaching and bio-softening of coir yarn in order to reduce the requirement of softening and bleaching chemicals in wet processing of coir was studied. Treatment of coir yarn for 72 hrs using Trametes versicolor (NCIM 993) and Coirret, a bacterial consortium was carried out. The bio-treatment could impart an appreciable degree of softness to the yarn which was confirmed by the Flexural Rigidity Test. An improvement in softness of the yarn to the extent of 38% using bacterial treatment and 46% using fungal treatment was achieved. A noticeable change was observed in surface morphology of the fibre through SEM analysis. The lignin content of the fungal treated yarn was also reduced to some extent. An increase of 10% in Brightness Index of the fungi treated yarn was observed and a reduction in the requirement of bleaching chemicals could also be achieved. The physico-chemical parameters of the residual bleach liquor were also studied and a considerable decrease in BOD, COD and phenol content was observed.

Abstract

Novel uses of Makapuno mutant coconut were explored. The focus was on the endosperm, which is rich in galactomannan as compared with that of the normal coconut. Galactomannan, also referred to as gum, is a non-starch polysaccharide that can vary in physicochemical properties depending on the plant source. The galactomannans available in the market are imported and sourced mostly from temperate leguminous plants. An inexpensive, large-scale method of isolating galactomannan from waste Makapuno liquid endosperm was developed. The powder produced could be classified into different grades according to purity, fineness, color and whether it is food-grade or not. It has the functional properties of a thickener, binder, extender, gelling agent, emulsifier and stabilizer. To showcase the use of Makapuno galactomannan as a plant-based biopolymer and a hydrocolloid material, several formulations were tried and tested to come up with products such as biodegradable or edible film, jelly, hand and body lotion, and even electrophoresis gel. However, they have to be further improved in terms of quality, shelf life and safety for commercialization to be considered. Other prospective applications of Makapuno galactomannan are discussed.

Abstract

A study was conducted to evaluate Sri Lanka’s dikiri coconut for toffees, Dikiri spread and ice cream. The prepared products were tested for their physico-chemical and sensory properties. Initial trials were done in Sri Lanka to identify the best Dikiri kernel/sugar ratio for toffees, showing that a 1:1 ratio gave acceptable quality. Prepared Dikiri spread was compared with margarine-based bread spread. Results revealed that the product was more acceptable in terms of taste and overall acceptability compared with the margarine-spread. The Dikiri spread comprised 7.95% minerals, 11.35% crude fat, 2.68% crude protein, 4.95% crude fiber and 73.07% carbohydrate on dry weight basis. Dikiri-added ice cream was acceptable and comparable with regular dairy ice cream. Composition of the Dikiri-added ice cream conforms to Sri Lanka Standards.

Abstract

Recent advances in the spread of the Cape St Paul Wilt disease (CSPWD) necessitate a more rapid development of tolerant coconut types. Control pollination is the main method for producing legitimate coconut seeds for such breeding purposes. However, the process of bagging causes severe nut drop or abscission. Many scientists have implicated hormones as the primary regulators of organ abscission; with ethylene being particularly implicated. Unlike other plant hormones, which are mainly produced in other parts and transported to influence target organs, the production of ethylene could be initiated within the same organ, such as the fruit. This study was therefore undertaken to investigate the possible involvement of ethylene in abscission after control pollination. Pollen from Vanuatu Tall (VTT) variety was used to cross emasculated Malayan Yellow Dwarf (MYD) inflorescence after isolation with bags. Trials were laid out in Completely Randomised and Split Plot designs, with specified replications. Two ethylene inhibitors, namely aminoethoxyvinylglycine (AVG) and silver thiosulphate (STS) were used. Five concentrations of AVG ranging from 2mg/l to 30mg/l were applied to inflorescences during and after bagging. AVG concentrations higher than 2 mg/l resulted in significant reduction in abscission. Fruit yields up to five times that of ordinarily bagged treatments without AVG were recorded. Four concentrations of STS ranging between 0.5mM – 10mM applied in similar manner, however, did not result in any significant reduction in abscission. The results from AVG application strongly suggest the involvement of ethylene in the abscission of control pollinated coconut fruits.

Abstract

Dipha (Conobathra) aphidivora Meyrick (Pyralidae: Lepidoptera) is recorded for the first time as a predator of coconut mealybug, Sangicoccus sp. (Eriococcidae: Homoptera)) in the Philippines. Some aspects of its biology and ecology were studied to determine its suitability as a biological control agent against Sangicoccus sp. The life history of D. aphidivora was investigated following the establishment of a rearing procedure. The incubation period of the egg was 4.64±0.70 days. The four larval instars larva were completed in 5.52±0.92, 3.40±0.91, 2.83±0.72 and 3.40±1.04 days, respectively. Adults emerged from pupae after 7.68± 0.99 days. Adult longevity was 6.83 ± 2.30 days. The life cycle of D. aphidivora lasted for 32.42±3.63 days. Voracity tests showed that the four larval instars of the predator consumed an average of 150 mealybugs.

Abstract

Coconut (Cocos nucifera) is one of the important tropical oilseed crops grown in more than 80 countries. It is called the ‘Tree of Life’ because every part of the palm finds one or other use in everyday life. India is one of the leading coconut producing countries in the world and many millions of Indians are dependent on this crop for their livelihood. Many research experiments are in progress to increase the yield of this crop as well as develop post-harvest products that will improve the socio-economic status of the farmers who cultivate it. The coconut cropping system, being unique, offers a wide range of ecosystem services which has not been studied in much detail. A recent paper from Philippines, however, throws some light on the importance of ecosystem services offered by coconut types. In this article we attempt to enunciate the ecosystem services provided by coconut in Indian scenario and the possibility of sustaining it through the recycling of coconut leaf litter as vermicompost.

Abstract

The farm level technology of processing coconut sap sugar from toddy is a social enterprise which created a significant change in the livelihood of the people dependent on the coconut trees in Aroman, Carmen, North Cotabato. Technical skills acquired through training, appropriate facilities, capital and access to market are the key factors in developing a farm-level technology were used to emerge a commercially viable social enterprise. Indicators of change were gauged through change in income, equality of income distribution and preference in household expenditure. The increased income was disposed of by an increase in the cost of living and altered purchasing preferences. Significantly, the highest change of expenditure was on food and less in education notably 25.81 and 20.44 percent. In the case of income distribution, even with 2.39 percent increase on the percent share of the lowest 20% income group, there was an improvement in the income of the farmer-processor “after” the project implementation. But still, the community remains within the inequitable income distribution status group. It is expected that another year of business will have further favourable impact on income distribution among the respondents.
