Abstract

Trichoderma harzianum multiplied in farm yard manure and applied with neem cake to coconut palm affected by basal stem rot disease reduced the severity of the disease. T harzianum applied in coconut basins survived for more than one year, though the population gradually declined after four months. Application of Azotobacter or phosphobacterium (200 g peat based inoculurn) to basal stern rot disease affected coconut gave lesser increase in disease index than control and increased the nut yield. Tapping for neera production in mild and moderately diseased palms showed lesser disease index than untapped palms of corresponding disease severity.

Abstract

The biology and mass rearing of Eucanthecona furcellata Wolf, a polyphagous predator, was studied under laboratory conditions. The predator has a total life cycle (egg to adult) of 46.25 days. The egg hatched 6 days after laying. The nymphs undergo seven instars with each stage ranging from 2.0 ‑ 2.35 days. Mass‑rearing techniques, effect of field releases and other ecological factors on pest population as well as other biological informations are also described.

Abstract

Biomass production, nitrogen yield and nodulation by ten species of green manure legumes were compared in coconut basins in a root (wilt) affected garden under laterite soil type. Pueraria phaseoloides, Calopogonium mucunoides and Mimosa invisa were superior to others and yielded 28.45, 27.21 and 24.97 kg of biomass and 196.2, 186.5 and 187.6 g of nitrogen basin-1, respectively. The performance of Mucuna bracteata Crotalaria juncea and Macroptilium atropurpureum were also better with a biomass production of 16‑21 Kg basin-1 and nitrogen yield of 108‑140 g basin-1. Incorporation of green manures obtained from C. mucunoides, P. phaseoloides and M. invisa resulted in an increase in the level of major nutrients viz. N, P and K in coconut basin soils. Mineralisation of carbon was also greater in green manured coconut basin soils when compared to that in control. The increase in nutrient levels and mineralisation of carbon was more in treated basins at 30 days of incorporation of green manures when compared to the levels before the harvest of the legumes and at 60 days of incorporation.

Abstract

Coconut farmers in the Philippines use different types of copra dryer in copra processing. Copra quality and income are very much affected by the type of dryer used. In the country, there are indirect, direct, and semi‑direct type dryers. The common types of dryer used by the coconut farmers especially in the Visayas are direct and semi‑direct ones. There is high probability of the direct dryer together with the copra in getting burned because the firing place is directly under the drying platform where the coconut meat is placed. Especially if the meat is reaching 10% or lower moisture content where oil is coming out and the fire is immediately under it. Semi‑direct type dryer is quite comfortable to use having the less probability of burning the copra and the dryer because the firing place is away from the drying platform. The firing place is only linked to the drying platform by a tunnel.

Abstract

Severe nitrogen‑deficiency in unfertilized plots resulted in low bearing percentage (19.62%) of the palms. Highest bearing percentage of 68.82% was observed on palms applied with 1.5 kg ammonium sulfate per palm per year. Application of 2 kg ammonium sulfate/palm/year resulted in most number of harvested nuts. The yields of palms applied with 1.5 kg ammonium sulfate or 0.66 kg/urea/palm/year were, however, not statistically different from the former. Similar trends in fresh meat and copra yields were observed. Copra yields were significantly higher in plots applied with inorganic N fertilizers.

Abstract

Three methods for coconut oil extration using acetic acid, baker's yeast, and mixed enzymes were investigated. Coconut milk was allowed to settle for two hours; for cream separation. When the cream reacted with 25 % acetic acid at 0.l % ‑ 0.4 % levels or baker's yeast at 0.5 ‑ 2 g levels for 10 ‑ 14 hours, the oil was separated into two phases; the upper phase containing coconut oil‑rich fraction and the lower phase consisting of water. The oil phase was finally boiled for 20 minutes to remove moisture. The other extraction method was based on the combined action of cellulase, a ‑amylase, protease, and poly‑galacturonase at 0.1 % to 1 % on grated coconut meat at pH 4 to 8, 400C to 600C for 30 minutes. Oil recovely, moisture content, FFA, peroxide value, saponification value, anisidine value, iodine value and colour of the oil were studied. Up to 60 % recovery of high quality oil was obtained by acetic acid or baker's yeast treatment whilst that of mixed enzymes treatment was 73 %. These three alternatives wet processing showed significant improvement as compared to the traditional process.
