Abstract

Records of disease occurrence in surveyed provinces show Davao del Sur having the highest disease incidence of stem bleeding caused by Thielaviopsis paradoxa (de Seynes) von Hohnel. Disease incidence in Malayan Yellow Dwarf x West African Tall (MYD x WAT) hybrid at the PCA’s Zamboanga Research Center was relatively lower than the other areas observed. Tall genotypes are less susceptible to the disease as shown in the province of Quezon where the cultivar Laguna Tall is predominantly grown. The incidence of stem bleeding was found to be related with palms age. More incidence of the disease was noted in palms between 11-15 years old. Study on the spatial distribution of the disease from l991 to l995 show that the disease initially occurred in random foci, and, subsequently infected adjacent palms. The disease progress curves suggest that stem bleeding follows a sigmoid curve. It follows that the progress of the disease at any given time is a function of the initial inoculums and the number of effective contact points between susceptible host and inoculums per unit time. Analysis of the infection rates using logistic growth model showed that the rate of disease increase ranged from 0.029 to 0.218 per unit per year and 0.227 per unit per year in all the six experimental areas. Increase in disease incidence is directly related to high amount of rainfall.

Abstract

The effects of chlorine and potassium on the leaf morphology of 6-year-old PB 121 hybrid coconut palms were studied in 1995 and 1996 in southern Lampung (South Sumatra, Indonesia). The parameters considered were frond and leaflet size (length, maximum width, area) and their number. Chlorine and potassium had an exclusive effect on leaflet size, increasing their area. Potassium primarily affected petiole length, hence total frond length. Synergy between these two ions only occurred for the number of leaflets. Chlorine and potassium acted independently on stem diameter and synergistically on height. Coconut palms receiving potassium or chlorine had significantly more voluminous leaf crowns. As time went by, this phenomenon increased despite constant monthly leaf emission. In a situation of equilibrium, the much larger mean crown area and leaf area index of coconuts receiving chlorine and potassium augured well for an earlier start to bearing and higher nut yields.

Abstract

In recent past the concept on the use of coconut oil (CNO) by the householders in Sri Lanka has been changing due to various reasons. The reasons were studied using the generalized linear models for the survey conducted during May/June 2001 for 366 householders representing three different population sectors (urban, rural and estate) and different income groups. The significant factors influencing the use of CNO are the type of oil used in past, monthly income, quality of CNO, misconception about CNO and the population sectors. The percentage of non-CNO users is considerably higher in the urban sector, whereas CNO still is the major edible oil in the rural and estate population sectors of Sri Lanka. The percentage of householders using CNO in the sample was 91.2. In 75% of the sample, the quantity of CNO consumption per person has reduced over the last five years. The main reason for dissatisfaction for CNO is adulteration. The proportion of CNO use was significantly higher in lower income groups than the higher income groups. The proportion of the CNO use decreased sharply when the income increases above Rs. 40,000 per month. The high-income earners have shifted their preferences towards other edible oil consumption. The findings of this study suggest that the growth of the per capita incomes and the rapid urbanization in the country further reduces the consumer demand for coconut oil, unless there are effective marketing strategies implemented to promote the CNO consumption in the long run. Both the proportion and rate of CNO use can be increased through an effective campaign via media. Improving the quality and dispelling the misconception among the householders would give better prospects to the coconut oil industry in Sri Lanka.

Abstract

An excellent way of producing a reliable mapping population for quantitative trait loci analysis and marker assisted selection was considered. A physical mapping method known as ‘Happy Mapping’ was discussed to make a framework map as an alternative to overcome the problems associated with meiotic mapping.

Abstract

Coconut leaf rot in association with root (wilt) is widespread in southern districts of Kerala, India. The disease complex has spread to northern districts of the state and also adjacent districts in Tamil Nadu. Where as the root (wilt) is a systemic infection (due to phytoplasma) the leaf rot is a foliar syndrome due to fungi (Colletotrichum gloeosporioides, Exserohilum rostratum, Fusarium spp.). Occurrence of leaf rot has been related to the incidence of root (wilt) and its appearance in young palms remained a matter of contention as to which disease precedes the other. Leaf rot lesions do occur on leaf petiole/mid-vein/mid-rib even as the disease lesions are known to be common on lamina (spindles). Investigations brought out that in majority of leaf rot affected young palms (2-5 years old) the flaccidity symptom of root (wilt) could be also discerned. In lesser number of affected palms, the other symptoms of root (wilt), yellowing and marginal necrosis, were also visible. As such, in 88.5% of leaf rot affected young palms one or the other symptom of root (wilt) has been recorded irrespective of season. C. gloeosporioides, E. rostratum and other fungi were found both in lamina and petiole lesions in different months. C. gloeosporioides was detected from petiole and lamina tissues in all the months, followed by E. rostratum, Fusarium spp. etc. C. gloeosporioides was isolated from these parts in more numbers and consistently during January-December. E. rostratum appeared erratically. Aggressiveness of C. gloeosporioides during months of wet season was confirmed. Fusarium spp. was isolated predominantly from these parts in dry months (January-May). Knowledge on occurrence of leaf rot in young palms in relation to root (wilt) and dynamics of leaf rot pathogens in leaf parts among months/seasons of year (in inoculums build-up, spread and dissemination) are important in the context of integrated management of root (wilt)-leaf rot complex.

Abstract

The variability of the nutrient contents and chemical properties of coir dust or coco peat derived from coconut husk in different locations was noted. Coir dust is a good supplementary source of N, P, K and Cl, including micronutrients (B, Cu, Fe, Zn, Mn). The coir dust acidity ranges from pH 5.2 - 7.0, and EC from 0.10-1.67 ms/cm based from: fresh (1 month), 3 – 5 months, and 1 year open-field piling (storage). Higher contents of nutrients K, Cl, and Fe of coir dust under coastal area was noted; but contents of N, P, Ca, Mg, S, B, Zn, Mn and Cu were found similar in coastal and inland areas. Under rainfall in open-field piling, Cl dropped to <0.25% at 3 – 5 months and <0.12% in a year’s time period. Moreover, a significant reduction of <0.30 and <0.15 EC (m/cm) in mentioned periods were indicated, respectively. Generally, as compared with other nut components, coco husk and the coir dust did not differ in nutrient contents and chemical properties. As composting material, either alone or in mixes, coco peat showed to be a supplementary source of P, K and Cl. NPK ratio was 2:1:2; and organic carbon content ranged from 6.34 - 12.07%

Abstract

Lethal yellowing disease has been rife in West Africa, especially Ghana, since 1932. In the 1990s, the first operations to fell diseased coconut palms at an early stage showed that this substantially slowed down the spread of the disease. Trial conducted in 1995 showed that early felling of diseased coconut palms, even without prior treatment, considerably slowed down the spread of the disease. Replications of this action in several other plots kept them healthy for many years. These positive results made it possible to obtain funding from Agence française de Développement (AFD) to maintain a "sanitary cordon" in the far West of the Western Region of Ghana, near the Ivorian border, where there is a wide area of coconut palms.

Abstract

The awareness, knowledge, attitude and adoption of the root (wilt) management practices were found to be very low among the farmers of root (wilt) affected area. This disease affects the socio economic conditions due to the reduction in coconut yield. Central Plantation Crops Research Institute, Kerala (India) has developed effective integrated management technology for improving the health and yield of disease affected palms. Due to the perennial nature, prevalence of the disease in the State for more than ten decades, attitude of the farming community and other social/economic constraints, the linear model of Transfer of Technology (TOT) could not create the desirable effect. Hence an innovative Participatory Technology Transfer (PTT) approach was implemented in severely root (wilt) affected district-Alappuzha during 1999-2003. The impact analysis indicated significant improvement in awareness (14 to 32.5), knowledge (19 to 59.5), attitude (22.5 to 36.5) and adoption (16 to 45.5) of practices as well as the scope for scaling up the TOT model in root (wilt) affected areas. The PTT enabled participation of major stakeholders in the TOT process. The categorization of the farmers indicated significant shift to the higher level of awareness from 63.00 to 92.00 %, higher level of knowledge from 14.00 to 74.50 % and higher adoption level from 27.50 to 57.00% after three years of PTT approach implementation.
