International Coconut Community Journal Vol 28 No 1 (2012): CORD
Publisher : International Coconut Community

King coconut (Cocos nucifera var. aurantiaca) water is a natural, nutritious and healthy beverage. However, it is underutilized in terms of value addition with extended shelf life. Therefore, an attempt was made to develop the physico-chemical and processing parameters for the value addition of King coconut water with extended shelf life. King coconut water was analyzed for sugar, minerals and vitamin C content based on reviewed methods. Studies were conducted to identify the optimum pH, total soluble solid (TSS), type of acidulant and pasteurization conditions based on sensory properties of the product using semi trained panelists. Processed King coconut water was packed in three different packages and stored at refrigerated (4°C) condition for two months. Changes in pH, TSS and titratable acidity were evaluated in two weeks intervals throughout the storage period. The results showed that optimum pH, TSS, type of acidulant and pasteurization conditions were 4.4, 9, malic acid and 70˚C/15 sec., respectively. The product was microbiologically (less than 50 CFU/ml) safe for consumption even after 8 weeks of storage. These storage studies revealed that the changes in pH, TSS and titratble acidity of King coconut water packed in three packaging materials had no significant difference (p<0.05) during refrigerated storage.

A study was carried out to distinguish coconut oil from coconut pairing oil by the application of principal component analysis (PCA) to fatty acid compositional and iodine value data. Five samples of ordinary coconut oil extracted from five different batches of copra and five samples of coconut pairing oil obtained from five batches of dried coconut pairings were employed. Fatty acid composition and iodine values of oil samples were determined individually and the data were analyzed statistically. PCA analysis showed that lauric and oleic acid contents and iodine value data are the most influencing parameters to discriminate coconut oil from coconut pairing oil. Hence, the application of PCA to fatty acid compositional and iodine value data was successful in distinguishing coconut oil from coconut pairing oil.

Publisher : International Coconut Community

Coir pith is lignocellulosic in nature and abundantly available by-product of the coir industry. It is a pollutant as it is resistant to biodegradation in the environment. It is mainly composed of cellulose (28%), hemi cellulose (9.5%) and lignin (31%). In this study, cellulose was extracted from the coir pith, and treated generally for the production of nanocellulose. Cellulose is proved to be a versatile material due to its unique chemical structure, which provides a superior platform for several new biomaterials. Nanophase materials are prepared from inorganic materials and hardly any are reported from natural products. When particles are made up to nano size their reactivity increases. FT-IR, TGA, XRD and SEM characterized the extracted cellulose and nanocellulose. The hydrolyzed nanocellulose was found to be the mixed crystalline forms of cellulose I and II. Conversion of this lignocelluloscic biomass to nanocellulose will lead to the preparation of new-nano composites materials for biomedical applications.

Coir is the natural hard fruit fibre extracted from the exocarp of the coconut. The fibre has over 40 percent lignin and is spun into yarn and rope. Coir is used globally for manufacturing floor coverings as home furnishing. The Coir Industry enjoys the status as the largest cottage industry in Kerala giving employment to over a million people, of which 80 percent constitute women. Coir pith is a biomass residue generated during the extraction of coir fibre from coconut husk. Coir pith produced during coir fibre extraction is of environmental concern as its dumping on shore line and leaching of its constituents alter water quality and aquatic life. Management of coir pith is a major problem with all coir industrialists. Hillocks of coir pith accumulate in the vicinities of coir fibre extraction units in Kerala, Tamil Nadu, Andhra Pradesh, Karnataka, and Orissa. These agricultural wastes have traditionally been disposed by burning which resulted in various environmental problems. Therefore, composting is an alternate way to dispose coir pith and is of critical importance. Ligninolytic enzyme production during coir pith composting by Pleurotus sajor caju has been studied in detail. Pleurotus sajor caju produces oxidative enzymes which degrade lignin in the presence of urea as nitrogen source. Substitution of urea with vegetative sources has resulted in the vigorous growth of the mushroom which leads to decreased lignin content and C: N ratio in the biodegraded coir pith. Combination of Azolla and Soya hulls as biological supplements was observed to be the best substitute for lignin peroxidase and manganese peroxidase production. Activity of manganese peroxidase and lignin peroxidase was maximum on the twentieth day of fermentation of coir pith. The level of enzyme activity during biological composting using vegetative sources was compared with the conventional process using urea. The enzyme profile exhibited variation with change in substrate and duration of decomposition. The colonization of Pleurotus sajor caju by its utilization leads to biochemical changes in coir pith converting it into an ideal plant nutrient.

Vermiwash, produced from actively vermicomposting substrates of coconut leaf + cowdung by the action of Eudrilus sp., has an alkaline pH, contains major and minor nutrients, growth hormones, humic acid and plant beneficial bacteria. Application of appropriately diluted coconut leaf vermiwash has shown to increase germination and seedling vigour index of cow pea and paddy seeds in laboratory bioassays. Field trials with cowpea, maize and bhendi (okra) in CPCRI farm showed its capacity to increase biomass and yield of the crops accompanied by enhanced soil microbial activities. Application of the vermiwash in red sandy loam soil produced an increase of 36% of fresh biomass weight, nodule numbers and 43% nodule fresh weight in cowpea at 1:10 dilution compared to control. In maize, increase in cob yield by 5-10%, fresh cob weight increase of 29-64% and in bhendi 22 to 33% increase in yield were recorded when vermiwash was applied at 1:5 dilution. To validate these results, field trials were taken up in farmers’ plots at Majal and Edneer area in Kasaragod. Bitter gourd and cowpea crops were taken up at Majal while amaranthus, cowpea and green chillies at Edneer. The soil type was sandy loam at Majal and lateritic at Edneer. Vermiwash produced at CPCRI was used as treatment along with farmers’ practice as control. The mode of application of vermiwash, dilution rates and intervals of application were carried out by the farmers as per recommendations. Observations on yield of the crops in vermiwash applied plots were recorded by the farmers. A yield of 75 kg cowpea and 200 kg bitter gourd at Majal; 55 kg amaranthus, 155 kg cowpea and 10kg dried chilli at Edneer plot were recorded from vermiwash applied plots. In both the places, observations indicated that application of vermiwash resulted in yield of crops on par or slightly lower than the plots that received regular fertilizer inputs as per farmers’ practice. However, in vermiwash treated plots, the farmers listed many other important points viz. healthy plant and root hair growth, lesser pest and disease damage, larger leaf size and deep leaf colour, longer ability of plants to stay without wilting in field as well as longer time of remaining fresh in case of amaranthus after harvesting, etc. The soil analysis also revealed that application of vermiwash in both types of soils increased the bacterial, fungal, actinomycetes, free-living nitrogen fixing, phosphate solubilzing and fluorescent pseudomonad population, and dehydrogenase, urease and phosphatase enzyme activities when compared to fertilizer treated plots. This clearly established the fact that vermiwash enhanced the soil fertility status for production of quality yield of agronomic and horticulture crops.

Structure and chemical composition of coconut shell carbon with polyvinyl alcohol (PVA) as the stimulant through the observation of TG-DTA, SEM-EDS, FTIR and XRD had been studied. The process was carried out by calcining coconut shell charcoal at the temperature of 873 and 1023 K under nitrogen flow, then mixed with polyvinyl alcohol (PVA) under composition of 2.5 to 7.5% wt. in water solvent. The development of carbon composite structure was observed by heating the samples in Argon gas of 1673 K, the rate of temperature was 10 K/min in 3 hours. The products were then analyzed by TG-DTA, SEM-EDS, FTIR and XRD. The result showed that the products were in uniform particle size of micrometer dimensions and spherical particles in shape, with average content of C element at 97.44% wt., aromatic character and semi-crystalline structure.

Do Belief Differences Lead to Change in Behavior? A Study of Sri Lankan Coconut Farmers Herath, C. S.
International Coconut Community Journal Vol 28 No 1 (2012): CORD
Publisher : International Coconut Community

Technology adoption by farmers is an important factor in agricultural development in both developing and developed countries that has not been achieved over the past years. The level of technology adoption is highly dependent on farmers’ beliefs and attitudes. Therefore, adoption studies are important to identify beliefs and attitudes of farmers that affect decision making. The present study tries to explain and identify the effect of motivation on farmers’ behavior to acquire knowledge and what are their beliefs and motives that underlie adoption of technology. The theory of planned behavior provides a structure to identify farmers’ behavioral intention with respect to attitudes, subjective norms and perceived behavioral control. The Self Determination Theory provides an explanatory system for the understanding of the motivation behind volitional behavior. These two theories serve as the key methodology for the study. The results revealed that, farmers’ participation in technology dissemination programmes and their willingness to gain information and skills have a significant relationship with intrinsic motivation. Further, those farmers hold positive beliefs towards new technology adoption and innovations. Therefore, two types of extension approaches are needed to enhance the technology adoption for intrinsically motivated and extrinsically motivated farmers.
