The processing of natural and nutritious coconut sap juice and coconut sap concentrate for commercial production was conducted by the members of the Samahang Magniniyugan ng Tawan-tawan (SMT) at Barangay Tawan-tawan, Baguio District, Davao City, Southern Mindanao, Philippines from February to May, 2007. The processing of coconut sap juice and concentrate involves simple, easy to follow procedures and few equipment are required. Results of the chemical analysis revealed that coconut sap juice, an oyster-white liquid and coconut sap concentrate, a sticky, golden orange syrup has 84.3% and 25% moisture content; 0.24% and 0.94% crude protein; 18.99 and 63.79 mg/100 mg sodium (Na); 0.85 and 1.51 mg/100 g calcium (Ca) and 0.05 and 0.33 mg/100g iron (Fe), respectively indicating that these coconut sap food products are nutritious and good for one’s body. While physical (color) analysis showed that these products are pure and natural since no food coloring was detected. A partial budgeting analysis on the profitability of producing coconut sap juice and coconut sap concentrate over the traditional fermented toddy indicated an additional profit or net income of Php19,728.00 and Php21,402.00 per month, respectively (Php41= $). The benefits derived from the commercialization of the technology on coconut sap food products by the adaptors were discussed. Factors for successful adoption and commercialization of coconut sap juice and concentrate were likewise recommended.

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.

The processing of coconut sap produced from the sequential coconut toddy and nut production (SCTNP) scheme was conducted at the Philippine Coconut Authority - Zamboanga Research Center, San Ramon, Zamboanga City from 1997 and 1999-2001 to determine their acceptability to local community members and evaluate their economic profitability. The processing of coconut sap into food products such as fresh sap beverage, coconut syrup, sugar and vinegar involves simple procedures at the farmer’s level. These sap-based food products proved to be highly acceptable in terms of their nutritional and economic values. They are rich in total solids, sugar (sucrose), protein, carbohydrates, phosphorus and amino acids. Coconut-sap sugar contains high amounts of essential elements such as N, P, K, Mg, Cl and S and micronutrients (B, Zn, Fe, Cu) compared to brown cane sugar and refined white sugar(almost without micronutrient). The production of sap beverage, syrup and vinegar showed higher farmer’s net income (PhP14,800 - 9,100/month) and return on investment-ROI (465%-380%) compared to sugar making (PhP 5,900/month, 278% ROI). On-farm production and processing of coconut sap-based food products have both social and economic advantages. This technology offers bigger opportunity for farmers to increase their income and generate employment especially to family members. Likewise, this product diversification scheme can promote multi-uses and competitiveness of the coconut palm.

The feasibility and viability of producing edible vegetative coconut pith or 'ubod' from young coconuts planted with double plants per hill under adult coconut bearing palms was studied at the Philippine Coconut Authority - Davao Research Center, Bago Oshiro Davao City. The average weight of 'ubod' from double planting scheme was 5.9 kg/palm (range 2.8 -9.4 kg) on the first year of 'ubod' harvest. There was a very slight increase (average of 0.2 kg/palm) in 'ubod' weight on the second year of harvest. The total ubod yield for two years harvesting schedule was 8.9 t/ha. Under the Davao growing condition, cost and return analysis of 'ubod' production in double plants per hill scheme indicated a total net income of P129,030 per ha in 4 years with a return on investment (ROI) of 180%. While copra production from adult bearing palms realized a total of P 114,675 for 4 years with an average ROI of 242%. Considering copra plus 'ubod' yield from this production scheme, the cumulative net income and ROI obtained were: P 242,389.6 and 203% respectively. Based on the results of this study with modest fertilizer application of ammonium sulfate plus common salt (NaCl), underplanting of two young coconuts per hill (spaced at two feet away from each other) at 3 x 3 m distance between spaces of bearing coconut palms harvested at three years from field-planting is a profitable and viable production scheme to increase farm productivity. The farm income with this coconut-based production is increased by 200% compared to coconut monocropping.

A 15- year (1993-2007) long-term integrated soil fertility management (ISFM) study on coconut (‘Laguna’ tall variety) + lanzones fruit tree (‘Paete’ variety) agro-ecosystem was conducted using five fertilizer combinations (FCs) in a dominantly tropical wet climate growing zone (Koppen-Geiger Climate Classification, Kottek et al 2006) of Davao, Southern Mindanao, Philippines (07o05’N 125o37’E. One of the objectives of the study was to determine the response of this agro-ecosystem to the combined application of inorganic multinutrient fertilizer (MNF): N+P+K+Cl+S+B (14% N-5% P2O5-20% K2O, with 15.5% Cl, 4.5% S and 0.02% B) and organic fertilizer sources at different ratios by weight by tree (IF+OF at 1+0; 1+2; 2+4; 4+2 and 4+4) on: crop productivity; soil properties, and leaf nutrient levels of the agro-ecosystem. The influence of ISFM and MNF on yields and profitability of the agro-ecoystem coconut and lanzones fruit tree crop (Part I) had been presented earlier in the CORD J. (Magat et al 2009) Results as presented in the first part of the work report showed that the application of the multi-nutrient inorganic fertilizer even at its lowest rate for coconut (1 kg/tree/yr) produced a significant increase in annual nut and copra yield per ha from an average of 8,890 nuts or 1.6 tons to 3 - 4 tons after 2 years of fertilizer applications. The non-significant difference in nut and copra yields of fertilizer combinations (FCs) in almost all years showed that even with the application of FC-1 (1 kg of inorganic fertilizer), the lowest rate of the multi-nutrient fertilizer, even without organic fertilizer, an annual yield over 4 tons copra per ha (or over 17, 000 nuts per ha) was produced in most of years of production, seldom achieved in coconut farms in the country. The improvement of coconut yield and very productive lanzones fruiting stage in this cropping system may be attributed to the significant influence of fertilizer combinations on the crops’ leaf nutrient contents as N, P, K, Cl and B. The long term effect of organic fertilization contributed much to the improved or enhanced soil physical conditions as the soil bulk density. Soil chemical properties as soil acidity, organic carbon (C), organic matter, available phosphorus (P) and exchangeable potassium (K) were generally enhanced during the 15 years of coconut and lanzones cropping under ISFM with multi-nutrient fertilizer application. This long-term coconut + lanzones cropping agro-ecosystem proved to be a sustainable farming system. The proper integrated soil fertility management (ISFM) as a major component of the integrated crop management (ICM) using the PCA-formulated crop-specific-fertilizer multi-nutrient 14(N)-5(P2O5)-20(K2O)-15.5(Cl)-4.5(S)-0.02(B) even at the lowest rate of fertilization contributed to stable soils resulting to the total productivity of the coconut + lanzones fruit tree agro-ecosystem.
