Abstract

The objective of the study was to (1) evaluate land suitability for coconut (cocos nucifera L.) production in relation to soil physical properties, (2) identify the soil physical constraints and (3) study their effect on the morphological adaptation of coconut roots. Soil physical properties were found to be significantly related to coconut yield (R2=81.37; p<0.01). Multiple regression with cluster analysis of soil physical properties vs coconut yield enabled classification of soil series into three major groups namely (a) highly (b) moderately and (c) less productive series. It was observed that the high soil compaction which limited the available water and aeration capacity of soils resulted in retardation of the activity of coconut roots. Water stress due to soil compaction was found to induce production of more inactive roots by suberization and dehydration processes. Scanning electron microscopic image showed that soil compaction and water stress, reduced the cell volume per unit area of the absorption zone and the number of pores in respiratory organs of coconut roots resulting in retardation of water and nutrient absorption, and air exchange processes. This in turn malfunctions of absorption cells and respiratory organs of roots resulted in retardation of growth of coconut seedlings. The practical importance of these findings in formulation of land suitability maps for coconuts is discussed.

Abstract

Recent developments in the world market such as the General Agreements on Tariff and Trade (GATT), quality management systems (ISO 9000), environmental management systems (ISO 14000), etc. force industries to re-evaluate their existing products and manufacturing systems and procedures. Suddenly, being ISO certified has become both the tool and the badge for the goal of global competitiveness. It is a well known fact that to be globally competitive and to be ISO certified, one must be able to produce quality products at the least cost and with the least waste of materials. This can be done by producing more value-added products from a single raw material with the least inputs.

Abstract

The AIDS pandemic has caused global concern what with its threat to man’s survival and the enormous cost to prevent and treat the illness. No effective cure is possible but for the last fifteen years, countless studies were made to improve survival, delay disease progression or just improve the quality of life. Various clinical trials were designed to inhibit specific processes that are necessary for the human immunodeficiency virus (HIV) to survive the internal milieu. As important as these discoveries, are the precise methods of measuring the impact of these treatments. Only in the last five years has there been a better understanding of these processes and methods.

Abstract

Despite the concerted efforts of successive governments in Sri Lanka to popularize coconut-based intercropping (CBI) systems, an intensive land use alternative to traditional less intensive coconut monocropping, its adoption by farmers is as low as 25% of the agronomically potential area of 100,000 ha. Although the adoption of an innovation is influenced by a range of determinants which can be broadly categorized as technical, economic, institutional and personal/social, economic profitability of the technology itself is one of the key determinants influencing its adoption. This study assesses the economics of widely practiced five different CBI systems vis-a-vis coconut monocropping, employing five economic indicators, namely Total Gross Margin (TGM), Net Present Value (NPV), Benefit-Cost Ratio (BCR), returns to labor and returns to capital. Data were collected by a field survey of 113 intercroppers and 37 monocroppers conducted from March to May 1995 in three main coconut growing districts in Sri Lanka, namely: Gampaha; Kurunegala; and, Puttalam. Results revealed that all the CBI systems give higher returns per hectare than coconut monocrops, though some of the indicators, namely BCR and returns to variable costs, are reasonably attractive for monocrop coconuts, albeit they are less than for some CBI systems. The study concluded that the low rate of adoption of CBI systems is not a problem of low profitability. Hence, it is worthwhile to explore the other factors typically influencing the adoption of production technologies to find out the reasons for low adoption of CBI

Abstract

A Tall x Tall coconut genotype resistant to basal stem rot (Ganoderma) disease has been developed for the first time in India. The resistant coconut genotype registered higher survival rate, growth characters and nut yield in disease endemic area. It contains more amount of phenolics, lignin, amino nitrogen and lesser amount of sugars which may be the factors responsible for the disease resistance.

Abstract

A new product using farm wastes from coconut plantation is being developed as an alternative building material. The product, coir-wood-cement board (CWCB), is made from husk fiber of coir and shredded sapling or excelsior that are mixed separately with cement at a predetermined ratio of 70% cement to 15% coir excelsior by weight basis. Mixture of saturated coir/excelsior and cement is mat-formed and pressed to the desired thickness and then conditioned by air-drying to produce CWCB. Its dimension is 61 cm wide and 244 cm long with thickness ranging from 8 mm to 25 mm CWCB meets the strength requirements set by PHILSA standard specification for particleboard (PHILSA 106, 1975). It is being service-tested as an alternative material for expensive construction materials such as plywood, particleboard and cement hollow blocks. It has been found suitable for such uses as exterior/interior walls, partition panel and ceiling of building as well as furniture components such as table top and cabinet siding. Production of CWCB needs the major equipment/machinery such as decorticating machine, shredding machine, blending machine, hydraulic press, trimmer and lifter. Except for lifter, these machines can be designed and fabricated locally. Estimated total investment cost of PhP 3.76 million is needed to establish a CWCB plant that includes equipment, land rental, building and working capital. About 37,500 boards can be produced every year with internal rate of return of 35.20% and payback period of 2.68 years.

Abstract

The soil and external supply of micronutrient boron (B) clearly affect the coconut crop’s growth and development; and, thus, the yield and quality of produce, particularly during the dry season (< 75 mm rainfall/month). A clear deficiency of B in young palms of several farms ( 11 out of 37) was observed in a project site of a nationwide multi-location piloting (MULTILOC ACTPRO) of coconut varieties and hybrids located in an inland area of Linabu, Balingasag, Misamis Oriental, Northern Mindanao, Philippines. The deficiency in young coconut is characterized by the presence of deformed leaf fronds or “little leaf”, followed by non-splitting or delayed opening of leaflets that usually appear in zigzag-like pattern in advanced or severe deficiency stage. The apical shoot blackens, exhibiting growth failure and death of tissues and plant per se. Photographs of the boron deficiencies in sample farms, and recommended correcting measures are presented.

Abstract

The changes undergoing in the microorganism population due to the application of phorate 10G, carbofuran 3G (@ 10 g a.i./ palm) and neem oil cake (@ 1.5 kg / palm) in the basin region of coconut growing in root (wilt) affected area was studied. Generally, a high microbial population was observed in the control plot. Carbofuran proved to be more toxic as compared to phorate as it suppressed the bacterial, actinomycetal, and free-living N2 -fixer’s number significantly. Against Nitrosomonas and Nitrobacter (nitrifiers), the influence was inconsistent. Neem oil cake enhanced bacterial and free-living N2-fixer count; against actinomycetes and fungi there was an initial stimulatory, and then antagonistic impact, whereas, it proved detrimental to the nitrifiers. From the six soil samplings done, spread over a period of six months, the microbial load was recorded to be high whenever there was moderate rainfall and medium temperature. Application of neem oil cake produced positive effect on the beneficial microorganisms as compared to the systemic insecticides.

Abstract

An integrated soil fertility management or ISFM on-farm trial was conducted at Barangay Tawan-tawan, Baguio District, Davao City in 1993 to 1999 to know the effects of organic and inorganic fertilizers on the vegetative growth, nutrient status and yield performance of intercropped Catigan dwarf x Laguna tall (CATD x LAGT) coconut hybrid better known as PCA 15–1 or CATLAG. Vegetative growth of CATD x LAGT palms revealed that ammonium sulfate + NaCl and goat manure + NaCl produced significantly bigger girth size on the first year and more number of leaves and living fronds on the second and fourth year, respectively. These treatments also enhanced early flowering (>50% @ 4.5 years) and yield (51-53 nuts/tree/yr @) 5 years from field planting) in hybrid palms. The organic fertilizers, i.e. goat manure and coconut husk, become more effective in their effect on the vegetative and reproductive characters of palms when combined with a Cl source (NaCl). The application of Cl nutrient contributed to the better performance of palms during the drought condition. The application of goat manure resulted in improved levels of soil nutrients as K, Ca, Mg and P, increased percent base saturation and lower soil acidity. The use of local hybrid, PCA 15-1 and ISFM-based low cost production inputs such as ammonium sulfate, goat manure/coco waste (husk) and common table salt as well as intercropping suitable crops under young coconuts is a profitable package of technologies capable of improving and sustaining coconut farm productivity in the Philippines.
