Title: ACHIEVING INSTITUTIONAL DEVELOPMENT THROUGH SEED PRODUCTION AND PROCESSING
Name: Elbert A. Sana, Ma. Cecilia. Salas, and Agustin B. Lunag
Abstract:

The NVSU Seed Foundation Project (NSFP) strengthened institutional linkage and expanded its seed production and processing operations. These two major activities contributed to institutional development through capacity building, facilities development, and inter-phasing research and development (R&D) with instruction and entrepreneurship.

NSFP’s collaboration with the Philippine Rice Research Institute (PhilRice), Institute of Plant Breeding (IPB), and the Bureau of Post-Harvest Research and Extension (BPRE) facilitated access to high quality seeds of improved rice and corn varieties, market of seeds, and a seed drying facility grant. Continuous inbred rice seed production and corn contract growing generated income for the project which financed training and monetary incentives for workers.

In addition, mature technologies on seed production (including seeds) as experienced and showcased in the project have been extended to NVSU’s own rice production in an inter-phasing scheme with the Business Affairs Program of the university. NSFP also started involving agriculture students in the project. Two (2) Bachelor of Agriculture Technology (BAT) students are currently preparing their microproject proposal involving a hectare for production of certified rice seeds based on NSFP’s production practices and management. The scheme is supportive of the present endeavor of PCARRD to motivate students of agriculture, forestry, and natural resources through enhancement of curriculum and entrepreneurial experiential learning.

Future activities of the project will include hybrid corn and vegetable seed production, consignment on seed market, and the up scaling of corn contract growing.

Title: RURAL ENTERPRISE DEVELOPMENT THROUGH INNOVATIVE GOAT PRODUCTION SYSTEMS (REGION II)
Name: Wilson A. Cerbito, Jonathan N. Nayga, Diosdado Canete, Manuel C. Galang, Ricardo Azarcon, Edsel Miguel
Abstract:

Rural-based enterprise development (RED) is a holistic approach to technology commercialization and enterprise building. A rural-based enterprise consists of three important components: (1) production system; (2) organization and management; and (3) linkages.

The RED project is implemented in four (4) regions of the country, Region 1,2,3 and 8. In Region 02, specifically in Isabela, the focal site is located in the municipality of Echague in Barangays Sto. Domingo, Anafunan and Malitao Alicia as the control site, in Barangays Aurora, Antonino and Del Pilar.

Comparative baseline data on goats’ technical performance indicate that major problems in goat production are high mortality rates, due to parasitism and diseases, slow growth of kids resulting to goats getting smaller, including marketing problems. All farmer-partners (100%) adopted the technology options, which addresse the mentioned problems. Other technology options preferred by farmers include strategic deworming, pasture/forage establishment for feeding of improved forage, upgrading and concentrate/vitamin supplementation with 90.0%, 80.0%, 80.0% and 70.8% adoption rate respectively by farmers-partners in the focal sites. Goat productivity in focal sites gave evidence of a 110% increase in the number of does from 114 does beginning inventory with 5.7 average doe-level to the current inventory of 240 does with 12.0 average doe-level from the total 20 farmer-partners.

Upgrading through the infusion of superior breeder bucks coupled with the adoption of complementary technology options significantly improved the quality of offspring and resulted in bigger size. Birth weights of goats are 2.35 kg, 12.95 kg for weaning weights, and the marketing weight is 26.55 kg. The total targeted adopters of the project is 80 farmer-partners including spill-over after two years. As of this report, there are 20 farmer-partners involved in the RED project and 60 farmers partners belongs to the spill-over category.

The study realized the Incremental Cost and Return of a 25-Doe Level Goat Enterprise using Partial Budgeting Analysis of 1-2 cycles (March 2008-March 2009) for PhP 92, 400, PhP 36,960 for 10 Doe Level and PhP 18,480 for the 5 Doe Level.

Title: STBF: A FAST-MOVING TECHNO-TRANSFER VEHICLE FOR ENHANCED PEANUT PRODUCTIVITY IN JONES, ISABELA
Name: Rose Mary G. Aquino, Florante Leano, Jr., Lanie Galla, Roger Salvador, Vanessa Joy Fortin
Abstract:

The Science and Technology- Based Farm (STBF) Project aims to address the need to increase peanut production and improve productivity in Jones, Isabela. The project started through the conduct of reconnaissance survey wherein farming situation and practices of the selected Magsasaka-Siyentista (MS) were gathered as reference in identifying best technology options (increase seeding rate and wider spacing of new varieties, seed inoculation, basal fertilization and gypsum side-dressing) for demonstration in the STBF. Important technology-showcasing events like conduct of field days/harvest festival, provision of trainings and IEC materials were also done to ensure technology transfer and adoption.

Results of the STBF in three (3) crop-cycles (2 wet season and 1 dry season trial) revealed significant increase on peanut yield and income. Obtained data during the 1st cycle 2007 wet season resulted to pod yield of 2,825 kgs/ha (using Asha variety) and 2,750 kgs/ha (Namnama-1 or NSIC Pn 11 variety) as compared to MS traditionally-managed farm yield of only 1,680 kgs/ha. Significant results were noted during the 2nd cycle (2008 dry season) and 3rd crop-cycle (2008 wet season) because obtained pod yield reached almost 3,240 kgs/ha using Asha variety.

The eventual adoption of science-based technology interventions had tremendously improved peanut income as shown in the partial budget analysis. Average added cost (across crop-cycles) of Php 7,084/ha due to adoption of S&T interventions gave an average added return of Php 20,903/ha. Convincing results during the field day were presented with the 30 farmer-students of Barangay Arubub and are now adopting the technology interventions. About 172 corn farmers in other Barangays are participating in peanut production.

Title: FERTILITY MAPPING, PROFILING AND DATABASE BUILDING OF CORN CLUSTERS IN CAGAYAN, NUEVA VIZCAYA AND QUIRINO
Name: Generoso M. Oli, Felipe S. Aguinaldo, Vernon C. Dabalos, Angelita B. Calubaquib, RamonP. Divina,Ma. Editha B. Guillermo, Eva V. Eslava, Jennelyn R. Binarao, Alejandria S. Dabalos,Isagani S.Cabalsi, Ed
Abstract:

The study aims to assess the fertility status of ten (10) corn cluster areas in the six (6) municipalities of Cagayan, two (2) in Nueva Vizcaya and two in (2) Quirino . Readily available fertilizer recommendation to individual corn farmers within the cluster was obtained, which serve as guide in fertilizer application. GIS software was used to develop thematic recommendation maps of Nitrogen (N), Phosphorous (P), Potassium (K) and soil pH for each cluster. Interpolation, geo-processing and other spatial analysis were used in obtaining individual farmer’s reference table for specific fertilizer application rate.

Developed maps and set of standard rate range for fertilizer application and soil pH, shows that Nitrogen (N) requirement for the whole cluster area of Villaverde, Quezon and Aglipay is at maximum rate (120 kg/ha), while majority (70-90%) of the areas of Lallo, Lasam, Pamplona, Penablanca, Tuguegarao City, Sta Teresita and Maddela are also requiring maximum rate of application. Phosphorous (P) requirement for these clusters are well distributed from minimum (20kg/ha) to maximum (60kg/ha) rate of application , with 40-50% of the areas in Sta Teresita, Villaverde, Quezon, Maddela and 30-60% in Lallo, Lasam, Penablanca, and Aglipay respectively. Lasam and Maddela are sufficient in Potassium (K), thus requiring minimum application at 30kg/ha. pH maps showed that majority of the areas of Pamplona, Sta Teresita, Aglipay and Maddela clusters range from strongly to extremely acidic thus requires application of lime. Soil acidity for other clusters are tolerable (neutral to moderately acidic) except for small portions where pH are under the range of strongly to extremely acidic.

The application of Geographic Information System (GIS) in determining the proper fertilizer requirements of the soil is a potential alternative strategy to address the issue of appropriate application of inorganic fertilizer to corn in view of soil laboratory facilities insufficiency and high cost of chemicals for soil analysis.

Title: A GEOGRAPHIC INFORMATION SYSTEMS-BASED DECISION SUPPORT SYSTEM FOR SOLID WASTE RECOVERY AND UTILIZATION IN TUGUEGARAO CITY
Name: Junel B.Guzman
Abstract:

A Decision Support System (DSS) was developed to analyze and simulate the solid waste flow of Tuguegarao City using Geographic Information Systems and Stella modeling software. It was parameterized using data and information on population, per capita waste generation, average annual growth rates of population and solid waste composition in order to predict the volume of waste generated, compostable, recyclable, collected, uncollected waste and compost under three waste management system scenarios.

Tuguegarao City generated a total of 1,012 m3 of household solid waste weekly in 2007, equivalent to a rate of 0.5 kg/cap/day and 0.42 kg/cap/day for urban and rural barangay, respectively. The commercial establishments, institutions and market generated at a rate of 384 m3, 209 m3 and 122 m3 of solid waste weekly or an equivalent total waste generation at a rate of 1,745 m3/wk.

The weekly solid waste composition was: 279 m3 (16%) paper, 105 m3 (6%) plastic container, 70 m3 (4%) metal, 70 m3 (4%) and glass 279 m3 (16%) as recyclable waste; yard waste, 506 m3 (29%) food waste, 122 m3 (7%) other organics as compostable waste; 209 m3 (12%) other plastics, 70 m3 (4%) inert, 17 m3 (1%) hazardous waste and 17 m3 (1%) special waste as residual waste.

Simulation results revealed that a decision to compost market waste (Scenario A) could result to waste conversion from 92 m3/wk to 237 m3/wk by year 2015 and by recycling institutional waste (Scenario B) could result to waste recovery from 171 m3/wk to 225 m3/wk by year 2015. Processing all generated compostable and recyclable waste (Scenario C) could recover 92 m3/wk to 1002 m3/wk of compostables and 171 m3/wk to 617 m3/wk of recyclables by year 2015.

To maximize the recovery and utilization of solid waste generated and to address the environmentally unacceptable burning and disposal of voluminous waste, solid waste management option for the city, Scenario C is recommended, provided that generators in all sectors will cooperate and adequate composting facilities will be made available.

Title: DIVERSITY STUDIES AND UTILIZATION OF INDIGENOUS VESICULAR- ARBUSCULAR MYCORRHIZAL FUNGI ISOLATED FROM CITRUS PLANTATIONS1
Name: J I. Yago, JM Sison, SG Mateo, KB Rivera, MP Gonzales, EI Bustamante
Abstract:

The study was conducted to collect and taxonomically identify existing mycorrhizae in citrus plantations in Kongkong, Muta and Malabing Valley in Kasibu, Nueva Vizcaya. It aims to analyze the diversity of indigenous Vesicular Arbuscular Mycorrhizal (VAM) fungi, to investigate the in-vivo compatibility and colonization of each VAM species in citrus root system; to study the nutrient uptake of citrus seedlings inoculated with indigenous VAM; and to determine the growth characteristics of citrus seedlings inoculated with indigenous VAM.

The sieving pan method was used for the isolation process. Taxonomic identification revealed that four (4) genus of indigenous VAM fungi were isolated namely Gigaspora, Scutellospora, Acaulospora and Glomus. VAM fungi isolated from Kongkong Valley showed the most diverse population of mycorrhizal fungi revealing 11 known species and three (3) unknown species presumed to be of the genus Glomus, Gigaspora and Scutellospora. Five (5) known species and one (1) unknown species of the genus Gigaspora, were observed in Muta Valley. Four (4) known species were observed to be present in Malabing Valley and the most dominant was Gigaspora gigante.

Diversity analysis found that diversity index value in Kongkong Valley was the highest (0.92) compared to Muta (0.53) and Malabing Valley (0.26). Species richness value was higher in Kongkong (7.85) which is located in lower elevation/areas. S value in Muta Valley recorded with a value of 5.54 while in Malabing Valley was 2.53. Repetition index in Kongkong Valley recorded with a value of 0.56 followed by Muta Valley with a value of 0.69 and 0.63 for Malabing Valley. Macronutrients were significantly enhanced when citrus seedlings were inoculated with VAM fungi compared to non-inoculated citrus plants. Results show that mycorrhizal fungi’s penetration to the root system is evident for symbiotic association. Thus, citrus growth characteristics were significantly affected.
