Abstract

The effect of rock phosphate on mature coconut was evaluated from 2004 to 2010 within the context of low nut yield due to phosphorus deficiency in the acidic soils of South-Western Ghana. A low reactive Togo rock phosphate containing 25.5% P205 was applied. Three application schedules based on 666 kg/ha rock phosphate and a control were evaluated in a Randomized Complete Block Design with five replications. The application schedules were: (a) Bulk application at 4.5 kg/tree (b) Two-equal-split application at 2.25 kg/tree in years 1and 3 (c) Three-equal-split application at 1.5 kg/ tree in years 1, 2 and 3. Muriate of potash fertilizer was applied at 2 kg/tree as basal treatment. Plot size was 0.2 ha comprising 30 trees. Nut load and leaf nutrient status of coconut palms were determined. Rock phosphate led to a significant (P<0.01) increase in leaf phosphorus and nut yield. It sustained a superior nut load for a 4-year period beginning from year 2 of application to year 5 with average nut gain of 19.0 per tree compared to 4.6 per tree in the control palms. There was no significant (P>0.05) difference in nut yield and nutrient status between bulk and split methods of rock phosphate application. A value-to-cost ratio of 1.5 was obtained thus indicating the profitability of rock phosphate application in the acidic soils of South-Western Ghana. Coir geotextiles find application in revegetation of slopes by stabilizing the soil through erosion control. It has been found that the longevity of coir geotextiles although highest among all the natural fibres, it is required to last for at least 5 years so as to sustain the vegetation on the slopes for a long term solution. Normally it is found that coir geotextiles lose their 50% strength in 6 months in contact with soil, therefore it is required to strengthen the coir geotextiles.

Abstract

Coir pith is a lignocellulosic biomass which is recalcitrant under ordinary conditions. Nitrogen fixation is commonly carried out in the soil and these soils acts as the medium for plant growth. This paper attempts to utilize coir pith as a substrate for two important nitrogen fixing organisms viz. Azotobacter vinelandii and Azospirillum brasilense. Coir pith was used as a source of carbon and energy by the bacteria and the ammonia produced during the process of nitrogen fixation was studied, the amount of ammonia produce indicates the fixation process by the bacteria. The present work succeeded in establishing the use of these two organisms to degrade the coir pith effectively and the resultant biodegraded material could be used as organic manure for plants.

Abstract

Coir geotextiles find application in revegetation of slopes by stabilizing the soil through erosion control. It has been found that the longevity of coir geotextiles although highest among all the natural fibres, it is required to last for at least 5 years so as to sustain the vegetation on the slopes for a long term solution. Normally it is found that coir geotextiles lose their 50% strength in 6 months in contact with soil, therefore it is required to strengthen the coir geotextiles. This work involves the coating of coir geotextiles with natural rubber latex which could enhance the longevity of coir geotextiles in various civil/bio engineering applications. The rubber latex coated coir geotextiles which are eco-friendly have superior mechanical properties and better durability compared to the conventional uncoated coir geotextiles. This paper reports the coating of coir geotextile using natural rubber latex and a comparative study of the physical and mechanical properties of the treated and untreated coir geotextiles.

Abstract

In the Gulf region, coconuts are almost exclusively produced from palms growing in the Sultanate of Oman, particularly in the extreme south-eastern coastal plain of the Dhofar Governorate, and specifically within the city limits of Salalah, between the Jebel and the sea. The importance of these coconuts is not only agricultural; historically, the Dhofar palms provided the basic materials to build boats for fishermen and traders on, around and eventually beyond the Indian Ocean. Coconut palms are now one of the main symbols of Salalah city and play a role in both the tourist industry and urban landscaping. In early 2009, twenty-nine sites, representing Oman coconuts on beaches and cultivated lands were chosen from the Dhofar region. COGENT descriptors and DNA analysis were used for the purpose of identifying coconut germplasm available in Oman. The presence was confirmed of varieties that were imported during the 1980s, such as Yellow Dwarf, Green Dwarf and King coconut from Sri Lanka, as well as Malayan Yellow Dwarf and F1 hybrids. The local Oman Tall has the same phenotypic characteristics as other coconuts of South Asia, East and West Africa, the Caribbean and the Atlantic coast of South America. Microsatellite markers, however, reveal a substantial genetic contribution of the South-East Asian coconuts, at levels that are comparable to those found in the Comoros and Madagascar coconuts. Hypotheses about the ancestry of the Oman Tall coconuts are discussed; two genepools are indicated, consecutively involving natural selection, dissemination by floating, domestic selection and dispersal by boat.

Abstract

An embryo cultured Makapuno (ECM) production scheme which is simpler, faster and more low-cost than the current protocol has been developed. With improvements in the ex vitro establishment environment, the cut-off age for in vitro stage of seedlings before they can be transferred to soil has been lowered from 7 to 4 months resulting in a shorter ECM production cycle from 13 to 10 months. The improvements simplified the current ECM production technique by doing away with several complicated in vitro cultural practices and ex vitro establishment steps. Overall, the new ECM production scheme lowered the cost of production resulting in more affordable ECM seedlings for the farmers. Financial analysis of a 10 year ECM seedling production venture projected much higher Internal Rate of Return, Benefit Cost Ratio and Net Present Value as well as shorter Payback Period with the use of the new ECM production scheme. With the new scheme, the break-even prices using marginal and full-cost operations were approximately 4 to 8 times lower than the current selling price for ECM seedlings. With these results, it is expected that more entrepreneurs will take up the technology for commercial production with a consequent massive planting of ECM and greater production of Makapuno in the country.

Abstract

Attempts were made to develop an appropriate low cost vinegar making technique and evaluate the physico-chemical, microbial and sensory qualities of the product. Coconut water was adjusted to four different levels of sugar levels (12%, 15%, 17%, and 20%) and pasteurized sweetened coconut water was allowed for alcoholic fermentation for one week by addition of baker’s yeast and then for acetic fermentation by addition of raw vinegar at 10%. Changes in alcohol %, titratable acidity, pH and yeast and mold count were determined periodically. Best treatment was selected for evaluation of the vinegar generator. Vinegar generator consists of a feeding device, an acetifier and a receiving trough. The acetifier was filled up with maize cobs soaked with mother vinegar. The maximum alcohol content was observed in 17° TSS coconut water sample on 5th day (9%) of alcohol fermentation and the same sample achieved the highest acetic acid level during acetic fermentation period. Results indicated that vinegar generator accelerates the conversion of alcohol to acetic acid within 5 cycles or runs. It takes about 32 hours to obtain the 4% acetic level. Sensory evaluation was done to determine the acceptability of product using 30 untrained panelists. Sensory evaluation revealed that coconut toddy vinegar and coconut water vinegar were highly acceptable for aroma, taste, color, appearance and overall acceptability. Mature coconut water can be used to produce vinegar with the aid of vinegar generator for accelerating the production process.

Abstract

Coconut is an important social crop of livelihood concern for millions of small- medium farmers. Leaf rot disease (due to a fungal complex-Colletotrichum gloeosoprioides, Exserohilum rostratum and Fusarium solani as major pathogens), in association with root (wilt), is a major problem of coconut in southern districts of Kerala besides certain districts in Tamil Nadu etc. Central Plantation Crops Research Institute (CPCRI) has evolved biological control technology for integrated management of leaf rot to improve the health of disease affected palms. Application of biocontrol agents in the disease affected areas was aimed for creation of widespread awareness on eco-friendly disease management, crop sustenance and in realizing human resource potential. Effective strains of biocontrol agents-Bacillus subtilis, Pseudomonas fluorescens and Trichoderma viride-were evolved, their multiplications in media including coconut water standardized and the antagonists’ processed into bioformulations (totally 2000 Kg. talc formulations evolved distributed/utilized). Coconut gardens and rural groups in various districts of southern Kerala (Thiruvananthapuram, Kollam, Alappuzha, Pathanamthitta, Kottayam, Idukki, Ernakulam and Thrissur), various blocks in Theni district besides specified blocks in Dindigul district of Tamil Nadu could be selected. Through effective contacts with extension-developmental agencies, coconut Research & Development (R&D) meetings etc. reached out to rural people and implemented the technology of mass production-use of biological control agents, and knowledge imparted to rural people. Conducted trainings and allied programmes by on-campus trainings (396 beneficiaries), off-campus trainings (1854 beneficiaries), household/field contacts of rural people (689 beneficiaries) and other awareness programmes encompassing lectures, interfaces etc. (661 beneficiaries) and enlightened women, rural people, youths etc. representing various locations (totally 3600 beneficiaries in three years). Field demonstrations of disease management with biological control agents in coconut gardens (55 units) besides clusters-compact gardens (1850 coconut palms) were also done. Also, promotional materials were made available to various stakeholders. An innovative participatory programme implementation approach for technology transfer was the outcome of the work. Creation of widespread awareness, percolation of knowledge on biocontrol agents to women and other rural people could be visualized that would go a long way.

Abstract

Gradient outbreak of coconut slug caterpillar. Macroplectra nararia Moore (Limacodidae: Lepidoptera) in East Godavari district, Andhra Pradesh during April-May 2009 is closely interlinked with rise in ambient temperature and humidity along the water bodies. This favoured large scale explosion of pest population leading to widespread damage in coconut plantations ranging from 90-95% in severely affected gardens, indicating the sporadic nature of the pest. Exacerbation by grey leaf blight fungus, Pestalotiopsis palmarum accelerated the damage causing rampant scorching of coconut leaflets in pest affected gardens. In the field, some caterpillars were found infected by entomopathogens. Light trapping is suggested as an effective monitoring tool and a feasible mechanical control strategy of the pest.

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.
