Abstract

Selected sample farms (79) under the Small Coconut Farms Development Project (SCFDP, Philippines) representing five (5) regions and nine (9) provinces were evaluated. The yield trends: (1) initial or benchmark; (2) during rehabilitation period (3-4 years); and (3) post-rehabilitation period (2) years were examined using the nut and copra yield estimation method of the PCA (MAGAT, 1995). On nut yield, the benchmark average annual yield of 35 nuts/tree increased to 91 nuts/tree during the rehabilitation (rehab) period but dropped to 70 nuts/tree during the post-rehabilitation (post-rehab) period or two (2) years without fertilizer application. This 160% increase in nut production (1995) followed by a reduction of 23% at the post-rehab period is indicative of a moderate to strong residual fertilizer effect after the significant rehabilitation of palms by fertilizer application (supplying mainly N, K, Cl and S fertilizer nutrients). On copra yield, the pre-rehabilitation annual copra yield of 0.94 t ha reached 3.01 t/ha during the rehab period, followed by a drop to 2.21 t/ha at post-rehab. The copra yield increase of 220% during the rehab (1995) is mainly due to the increase in nut yield and nut size or copra weight per nut. An average reduction of 27% during the post- rehab period was observed but in some areas the yield of palms dropped close to pre-rehabilitation nut and copra levels, suggesting lower degree of fertilizer residual effects compared to other coconut regions. Implications of findings in relation to the rehabilitation by judicious fertilization of low-yielding, nutritionally-deficient non­-senile palms are discussed.

Abstract

A bacterial consortium developed on coconut husk leachates could ret coconut husk steeped for retting in rap water in a period of three months. The quality of the coir fibre obtained was comparable to traditionally retted fibre. The consortia could also bestow a greater degree of softness to the mechanically extracted coir fibre. Coir extraction can therefore be practiced by supplying the consortia for retting of husk for production of fibre and enhance the commercial utilization of the husk in coconut growing regions of Asia.

Abstract

Occurrence of leaf rot disease (LRDC) of coconut is related to increased incidence of root wilt disease (RWD). The palms with RWD irrespective of age are susceptible, young ones are more susceptible to LRDC. Tender leaves especially the spindle play a critical role in LRDC incidence and the disease attributed to fungal complex. Among the 14 species of LRDC Angi, several were proved to be pathogenic; Colletotrichum gloeosporioides (Penzig) Penzig and Sacc and Exserohilum rostratum (Drechsler) Leonard and Suggs are discerned as the main pathogens. C. gloesporoides was aggressive during monsoons and positively correlated with rainfall and relative humidity (11% RH, whereas Erostratum less strongly correlated Fusarium spp. predominated in dry seasons. Importance of microclimate, survival and quiescence of the pathogens are to be determined. Diagnosis of RWD by techniques such as PCR and understanding the molecular basis of vulnerability of palms to LRDC would help to initiate early control measures. Planting of RWD cum LRDC resistantl tolerant varieties after eradicating the RWD infected palms is desirable. Protection ofyoung leaves by chemical or biocontrol agents or a combination of both with phytosanitation is important. 4 system approach with integrated measures needs to be utilizedfor sound management of LRDC.

Abstract

It is well known that copra manufactured from sub­standard nuts are invariably of poor quality. The reasons that lead to or poor quality are varied, depending on the nature of the defect of the raw material. However, a better understanding of the parameters that cause poor quality can lead to attainment of considerable advantages, through minimization of losses arising from deterioration of quality of the product. Though the copra manufactured out of substandard raw material may not strictly meet with the standards of up-market grades such as "Edible " or the "Milling Superior" (See Sri Lankan Standards for Copra) the losses associated with the conventionally practiced systems are evidently possible to be reduced by using appropriate drying techniques. The trials carried out indicate some variations in preparation of raw material and the drying regimes, suitable for substandard nuts depending on the defect of raw material.
