Common Plant

Coconut (Cocos nucifera L.) is common plant for the Moluccan farmers to apply local wisdom in cultivation, called sasi. This study describes sasi implementation of coconut cultivation in South Buru and its effects on the quality of the coconut harvest. The research was conducted by field observation and interviews. Data were obtained from coconut trees aged 16–25 years and > 30 years. There are two common methods of cultivation through sasi, religion-based permission (local church) and traditional sasi. Both forms of sasi have different indications. On the basis of the sasi system, coconut plantations cannot be penetrated for six months (a spell prohibiting access to the crop) and harvesting only takes place after the end of the sasi period (avoiding any risk of theft of the fruit). Yields on the 16–25-years-old trees had a weight of endosperms of 243–378 g and a thickness of the coconut endosperm of 9.2–12.2 mm over the monitored 10–18 months fruit age period, each showing a bell-shaped variation with a maximum for about 13 months old fruits. Yields on > 30-years-old trees group showed the same pattern. Thus, although sasi is useful for protecting the coconut fruit before harvesting, the implementation of coconut sasi for six months ultimately decreases the quality of the crops and postpones the best harvest time. Therefore it is recommended that the implementation of coconut sasi in South Buru be adjusted with the biological timing of coconut ripening.

Background: Despite the health benefits of coconut oil and its potential for economic development, the availability remain scarce and the cost very high. This is mainly due to poor extraction methods that in turn affect the yield and quality. Aims: To produce coconut oil using different extraction protocols and to compare the quality of the different oil samples. Study Design: The experimental set-up was of a completely randomized design. Place and Duration of Study: Department of Food Science and Technology, Michael Okpara University of Agriculture, Umudike, Nigeria, between August and October 2018. Methodology: Coconut oils produced by natural fermentation, centrifugation, freeze-thaw and solvent extraction protocols were analyzed for physical, chemical, sensory, microbial sensory properties. Results: The solvent extracted oil had the highest oil yield (23.12%) whereas fermentation oil, the lowest (14.19%). The smoke and fire points had 173.75 -176.60°C and 262.45 - 266.65°C respectively. Solvent oil had the highest saponification (261.33 mgKOH/g) and acid values (0.77 mgKOH/g). The oils generally contained more lauric (46.22-48.16%) and myristic (18.03-19.83%) acids. They were also richer in vitamins A (6.22-18.65 ug/g) and E (2.92-4.28 mg/100 g) than D and K. Fermentation oil had the highest microbial count (12.93×02 cfu/ml) whereas solvent oil had the lowest (5.05×02 cfu/ml). Conclusion: The methods used for the coconut oil extraction had significant impact on the quality of the oils. The highest oil yield was the centrifugation oil obtained from Centrifugation Method. The physico-chemical properties and fatty acid compositions of the coconut oils were comparable to international standards. Coconut oil extracted by freezing and thawing was the most preferred in sensory attributes.

Abstract A comparison was made of Canadian sphagnum peat (SP) and Philippine coconut (Cocos nucifera L.) coir dust (CD) as growing media components for greenhouse production of Dracaena marginata Bak. and Spathiphyllum Schott ‘Petite’. Three soilless foliage plant growing mixes (Cornell, Hybrid, University of Florida #2 [UF-2]) were prepared using either SP or CD and pine bark (PB), vermiculite (V), and/or perlite (P) in the following ratios (% by vol): Cornell = 50 CD or SP:25 V:25 P, Hybrid = 40 CD or SP:30 V:30 PB, UF-2 = 50 CD or SP: 50 PB. Dracaena root growth was not affected by treatments but there were significant mix × media component interactions that affected plant top growth parameters. In general, the growth and quality of D. marginata were reduced by using CD in Cornell, had no effect in Hybrid, and increased in UF-2. S. ‘Petite’ grew equally well in all growing mixes regardless of whether CD or SP was used; however, plants grew more in Cornell and Hybrid than in UF-2. S. ‘Petite’ roots, which were infested with Cylindrocladium spathiphylli, had higher grades when grown in CD than when the media contained SP.
