Abstract

The effects o f the quality qfwater, pH and state qf the medium on growth and development of coconut embryos in vitro were evaluated. Germination of embryos in Y3 liquid medium was not affected by neither wau ,r quality nor pH adjustment. These sug­gest that tap water could replace glass distilled water and gelling agent could be eliminated in embryo culture qf coconut. However, pH qf the medium has to he adjusted.

Abstract

An evaluation of the irrigation investments in smallholder coconut crop in Kerala State in India showed that the share of irrigation costs to total costs was 25‑50 percent in small irrigated holdings. Yhe average variable cost of irrigation was Rs. 1,667.36 and the average capital cost was Rs. 1,031.49 per hect­are. The irrigation investments showed wide varia­tions among holdings of different land categories and also different sources qf irrigation.

Abstract

Export onented brownfibre industry of Sn Lanka has been sustained during the last two decades with periodic fluctuations in the annual voluntes, showing a nett decline towards later years. The level of export volume in the past years show a strong correlation with the number of drought days in the coconut area during the particular year. The increased exportscan be expected to result in withdrawal of husk available for ap­plication in moisture conservation of the culti­vated lands. Yhe effect would be aggravated by most exports being effected in the drought years. High incidence offibre expons, as it seenu when viewed against the annual crop pattern, lead to a drop in the harvests of thefollowing years. Means of avoiding the damage, thus caused while maintaining a satisfactory level of exports, maybe the primary factor to be concerned with, in planning future develop­ment programmes.

Abstract

In coconut the dried endosperin known os the copra is the most important econontic product os it is from the copra, oil is extracted by crushing. To increase the copra content in coconut Haldane (1958) had suggested that it should be possible to compare the size, oil content and other characteristics of the nut borne on the same tree after using pollen from two different pollen parents. The also indicated that the hybrid vigour may possibly show in nuts derivedfrom cross pollination since hybrid vigour in some species is largely due to increased seed weight. If so, it is possible that a mixed plantation may produce a better crop than either of the two breeds when grown alone. Studies on the nut and copra characteristics of Tall x Dwarf hybrids and their reciprocals with their parents in coconut have indicated the importance of selection of pollen parents for producing proinising hybrids which will give better yields and also nuts of better quality and quantity of copra. Hence in copra improvement progrannne by hybridization, selection of parents is of great importance for the production of hybrids which will not only give high yield of nuts and also yield higher outturn of good quality copra. Attempts have been made to identify the best combinersfor the production of high yielding hybrids. Restilts obtained are dis­cussed in this paper.

Abstract

Comparative investment analysis was done on the eight coconut hybridsl cultivars under the Zamboanga condition using the Mul­tiple Budget (MULBUD) program. The, study aims to ovaluate and com­pare the economic profitability qf coconut hybrids/cultivars under two planting schemes and determine the best genetic materials that will provide the highest economic returns to coconut farmers. Analysis of the recommended varieties was also done using different product groups and coco‑based enterprises. The economic performance of each coconut hybrids1cultivars was measured using investment indicators like SNPV, BCR, and IRR. With copra and shell as products under the new planting scheme, the use of PCA recommended local hybrids and BAY is a more profitable investment compared with MAWA and the other tall populations. In general, the profit‑ability of coconut hybrids and cultivars was enhanced under the replanting scheme. Break even point was attained at year one due to the value of coconut timber obtained from the old stand. Results further indicated that the use of local hybrids and BAY is the best starting point in increasing farm income. However, higher returns were obtained when product utilization are diversified and coco‑based enter‑ prises are incorporated.

Abstract

The occurrenee of a dikiri type endospenn the porapol and kamandala forms of the vatiety (Typica), has led to the advancement of the hypoth­esis that dikiri is not a form of coconut with in the Typica vadety, but merely a kernel type, which can occur in any tall form of coconut. The argumentis also made that from an evolutionary point of view, the daid kernel is the manifestation for an undesirable allele, which has been made use of by man for his advantage. A review of the literature examines the mechanism of occurrenee of the dikiri charader and the explanation offered on the aber­rant condition of the dikiri kernel.

Abstract

Chromolaena odorata (1.) K. & R. is a tropical peren­nial weed species qf the Asteraceae family that has be­come a serious problem in coconut plantations in Sri Lanka and in the tropics of Asia and Africa. The history of distribution, habitat and economic importance is summarized The botanical features and seed biology of this species are presented in this review Finally in­formation on the control measures such as mechanical, cultural, chemical and biological methods is discussed.

Abstract

Three macapuno-bearing dwarf x tall coconut hybrid trees were observed to exhibit some characteristics influenced by the dwarf female parents. Flowering started as early as 39 to 57 months after planting. Intraspadix overlapping of 43 to 100% was also recorded suggesting moderate to high degree of self pollination. Macapuno yield ranged from 0-50% per bunch. The nuts resemble the female parents in form but were generally heavier. They were all classified as type l macapuno. Binomial test showed goodness of fit to 3:1 ratio of normal to macapuno nuts.

Abstract

Individual interviews were conducted to 24 purposively selected coconut tappers from Leyte, Samar and Cebu, Philippines to determine their tapping practices and observations and knowledge on certain phenomena exhibited by the tapped palm, as well as, the problems which confront them. Specifically, inquiries were focused on tree selection, spadix/inflorescence age appropriate for tapping, spadix preparation and stimulation, spadix care and maintenance, climatic considerations and relations, and temporary cessation of inflorescence production. Data revealed certain enigmatic phenomena and some inconsistencies to long‑held physiological facts. Moreover, respondents' observations strongly point out the toddy yield's extreme sensitivity to climatic and weather change which could be best validated by further coconut physiology research.

Abstract

Coconut is grown in more than 90 countries in the world and India occupies the third position with an area of 1.63 million hectares and a production of 12355 million nuts [Anon(a)1993‑94]. The crop makes a significant contribution to the national economy to the extent of Rs. 4,000 crores with an annual export earning of Rs. 126 crores [Anon (b) 1993‑94] per year which is much below its potential of more than 100 nuts per palm per year. Lack of adequate and proper management of nutrients is one of the reasons for this low productivity.
