  • Adoption of integrated vegetable agroforestry system among smallholder upland farmers in the Philippines
    Penaso, Anthony M.; Intong, Judith D.; Damag, Maria Emily S.; Marsh, Robin; Reyes, Manuel R. (2009)
    Preliminary results of a survey conducted among 50 smallholder upland farmers in the Philippines during the second crop period in 2007 showed early awareness (since 1960-1970) of the integrated vegetable agroforestry system technologies, particularly irrigation drainage, soil conservation and soil fertility management, and the vegetable agroforestry system, which 59-75% of them adopted in their farms. They however, just were aware of the existence of the drip irrigation technology in 2000 and it was adopted by only 25% of farmers. Problems encountered with the technologies included high costs of inputs, low and fluctuating costs of farm outputs and the dry spell during the period.
  • Adoption of integrated vegetable agroforestry systems (VAF) among smallholder upland farmers in the Philippines
    Penaso, Anthony M.; Intong, Judith D.; Damag, Maria Emily S.; Marsh, Robin R.; Reyes, Manuel R. (2008)
    This brief presentation offers an overview of LTRA-5 activities in the Philippines, with particular attention the TMPEGS framework of technology, markets, policy, environmental impacts, gender and scaling up. The particular location of Lapantan is also fleshed out in detail in terms of its potential for providing access to local and national markets for VAF products. The research affiliated with the presentation was recognized a 2008 Best Paper at Central Mindanao University.
  • Agroforestry and sustainable vegetable production in Southeast Asian watersheds
    Reyes, Manuel R. (2008)
    This presentation discusses the work and philosophy of TMPEGS, a partner organization for the SANREM CRSP LTRA (Long-term research activity) 5. A goal of LTRA-5's work with vegetable and agroforestry production in Vietnam, Indonesia, and the Philippines is to enhance vegetable-tree complementarity. Factors that can increase vegetable-tree complementarity include use of indigenous vegetables and drip irrigation. Also discussed are cover crops and reduced tillage, home gardens and commercial production, and termite control and weed management.

  • Agronomic response of eggplant on different rates of vermicast and inorganic fertilizer application
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Gonzaga, N.; Reyes, Manuel R. (2014)
    The conventional use inorganic fertilizers is expensive and growers are looking towards alternative inputs such as compost, manures, and crop residues to improve/maintain soil fertility. There is a need to improve nutrient management by eggplant growers to manage inputs more efficiently. The use of vermicompost and worm juice is becoming popular issue as part of integrated nutrient and pest management in vegetables particularly in Solanaceous Crops. Eggplant (Solanum melongena L.) is cultivated for the immature fruits which are either roasted, fried, stuffed, cooked pickled or processed. Young fruits are also eaten raw.
  • Analysis of TDR-measured soil moisture retention and soil organic matter variability under conservation agriculture production systems in Claveria, Misamis Oriental
    Ella, Victor B.; Reyes, Manuel R.; Mercado, Agustin R. Jr. (Philippine Society of Agricultural Engineers (PSEA), 2012)
    By utilizing the principles of minimum soil disturbance, continuous mulch cover and Diverse species rotations; conservation aims to revitalize soil properties sustainably. Conservation agriculture production systems have significantly higher residual moisture content when compared to the conventional plow-based systems. In addition soil organic matter at the upper soil layer (0-15 cm) in all CAPS treatments exhibited consistently higher values than the deeper layer (15-30 cm) regardless of fertility level. However the soil organic matter at the uppermost soil layer (0-5 cm) did not exhibit a well-defined pattern of temporal variation over time although the soil organic matter appears to increase under conservation agriculture and decrease under conventional plow-based system after 2 years of cropping.
  • Annual research activity report - TMPEGS INDONESIA: Indigenous vegetables
    Purwoko, Bambang S.; Susila, Anas D.; Syukur, M.; Palada, Manuel C.; Reyes, Manuel R. (Bogor, Indonesia: Bogor Agricultural University (IPB), 2008)
    Summary: The objective of this research was to determine the effect of different fertilizers and the effect of plant spacing (population) on growth and yield of several indigenous vegetables. Inorganic fertilization increased yield of beluntas, kenikir and kemangi. Fertilization did not give effect on katuk. Optimum population of katuk is 160,000 plant /ha, while for kemangi, the optimum population could not be determined. It could be increased to more than 200,000 plants/ha. There was no significant effect of plant spacing in kenikir. Three undergraduate students (all women) were involved. Two of them (Mega Ayu Lestari and Ratna Pambayun) graduated in September 2008. However, due to planting problem of terubuk, one of them (Nia Kurniatusholihat) will graduate later in December 2008. TMPEGS Indonesia had a meeting during preparation/proposal presentation at the early fiscal year and result presentation at mid fiscal year. Country coordinator invited researchers to discuss issues across fields. Result of the current research will be used as leaflet development and later be used for extension purpose in the next fiscal year.
  • Application of SWAT model to assess sub-watershed in Nghia Trung, Binh Phuoc Province, Vietnam

  • Assessment of environmental impacts of integrated vegetable-agroforestry (VAF) system in Nanggung, Bogor, Indonesia
    Raimadoya, M.; Reyes, Manuel R.; Srinivasan, R.; Heatwole, Conrad D. (Bogor, Indonesia: Bogor Agricultural University (IPB), 2008)
    Based on Proposal #9 of TMPEGS-Indonesia Year-3 (Y-3) Work Plan, the target in this period was the completion of the three main input components for SWAT analysis: Land Use, Soil and Slope Definition (WBS-300), and maintenance of ArcGIS 9.1 software license. These targets were almost completed except updated of ArcGIS 9.1 license which failed to be accomplished. Fortunately, the recent availability of open source package MapWindows-SWAT (MW-SWAT ver. 44SR), provided freely from www.waterbase.org by United Nations University (UNU), allowed the chance to complete early than expected all SWAT processing chain. Though it only used a low resolution global input data. SWAT-Indonesia now has the "advantage" to proceed with two options: Arc-SWAT or MW-SWAT. Accordingly, the scenario has been adapted to two-step approach: (1) a "quick yield" effort to complete SWAT chain process within Year-3 using MW-SWAT, and (2) an improved SWAT re-process in Year-4, to fine tuning the existing result with local input data (WBS-300) by applying MW-SWAT or Arc-SWAT option.

    Reyes, Manuel R.; The Natuculture Team (2012)
    Natuculture™ (pronounced nā-choo-culture) is any human made system that mimics nature in human disturbed landscapes. We have trained undergraduate students at NCA&T, high school students (Dudley, Page, Andrews, Smith, Southeast Guilford, Southern, Early STEM college at A&T), middle school (Neal) and Stoney Hill community to set up the systems, maintain and experimenting the system.

    Conservation Agriculture for Food Security in Cambodia and the Philippines

    Degraded landscapes are expanding annually in Southeast Asia. Rural poverty in upland communities increases pressure on natural resources like forest, soil and water . These are the last “capital” for the poor and they are rapidly diminishing due to non-sustainable management. Such practices reduce agricultural productivity, which in turn heightens food insecurity and exacerbates poverty.
