  • Agronomic performance of eggplant on different rates of vermicast, inorganic fertilizer and cover crop
    Mercado, Agustin R. Jr.; Arcinal, Gil A.; Gabitano, Bensive Mahinay; Gonzaga, N.; Dorahy, C. (2012)
    The conventional use inorganic fertilizers is expensive and growers are looking towards alternative inputs such as compost, manure, 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.

    Developing conservation agriculture production systems for sloping acid upland in the Philippines
    Mercado, Agustin R. Jr.; Arcinal, Gil A.; Edralin, Don Immanuel A.; Ella, Victor B.; Reyes, Manuel R. (2012)
    Degraded landscapes are expanding rapidly in the Philippines. Agricultural productivity is decreased which in turn heightens food insecurity and exacerbates poverty particularly on the sloping acid uplands which soils are inherently poor. Through conservation agriculture (CA) principles and practices of minimal soil disturbance, continuous mulching and diverse species rotations, constitute the best ‘tool box’ to create sustainable permanent cropping systems for annual crop production for sloping tropical uplands. These practices reverse soil degradation, increase crop yield and profits and reduce the labor burden on women. Researchers-managed and farmer-managed conservation agriculture production systems (CAPS) were evaluated across the landscape of Claveria, Philippines including crops and soil fertility management component researches. We found out that cassava (Manihot esculenta) + Stylosanthes guianensis yielded the highest biomass and total sales followed by maize-maize system which yielded better compared with other maize based CAPS. Interplanting maize either with cowpea or ricebean did not give better total grain and biomass yield, but provided higher sales due to relatively better price of beans. Interplanting of maize with cowpea and relayed with upland rice insured food and nutritional security to smallholders by shortening harvest periods to 60 days and increasing harvest cycles. Stylosanthes grown with cassava and maize yielded significantly better than Arachis pintoi than grown with maize. We found out the limiting nutrients were nitrogen (N) > phosphorus (P) > Potassium (K). Omitting N application reduced maize yield by 67%, P by 59% and 21% without K application. Optimum rate of NPK application for maize was 120-20-0, but maintenance K of 17 kg/ha was necessary. Promising varieties of maize, upland rice, cowpea, forage grasses, forage legumes, sweet potato, cassava, sorghum including “adlai” (Job’s tears) were identified out-yielding locally grown varieties in economic and biomass yield which are suitable for CAPS. Our research results can be extrapolated to other upland areas in the Philippines as well as other areas in Southeast Asia as Claveria represents the bio-physical and socio-economic environment of these areas

    Developing Conservation Agriculture Production Systems in the Philippines
    Mercado, Agustin R. Jr.; Arcinal, Gil A.; Edralin, Don Immanuel A.; Ella, Victor B.; Reyes, Manuel R. (2014)
    Conservation agriculture with trees (CAT) offers solution to this pressing problem through following 5 key principles: Minimum soil disturbance, continuous mulch, maintaining diverse crop species, integrated pests and nutrient management. CAT is very important in soil and water conservation, enhancing agri-diversity, improving farm carbon sequestration potential, maximization of land area usage in the Philippines as well as the reversal of soil degradation thus improving food and nutritional security of the upland dwellers.

  • Developing optimum level of soil nutrient management for maize in conservation agriculture production system (CAPS)
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Reyes, Manuel R. (2014)
    Maie is the main staple crop in the conservation agriculture production system in this acid upland soil where it is traditionally grown twice a year. Appropriate fertility management is important so that optimum yield and profit can be achieved particularly for smallholder upland farmers cultivating acid soils in the Philippines as well as in Southeast Asia in which environment dominates most of the non-irrigated areas. Identifying the most limiting nutrients and the optimum rates of their application are important for fertility management particularly in conservation agriculture production systems. In order to achieve this objective, we conducted an NPK omission experiment in two different planting spacing and this was followed by experiments on the different rates of NPK.
  • Evergreen Agriculture on Slopes
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Reyes, Manuel R. (2014)

    Forage herbaceous legumes evaluation for Conservation Agriculture Production Systems
    Mercado, Agustin R. Jr.; Arcinal, Gil A.; Gabitano, Bensive Mahinay; Reyes, Manuel R. (2014)
    This poster provides a brief description of a study on the use of forage herbaceous legumes in conservation agriculture production systems.
  • Forage herbaceous legumes evaluation for Conservation Agriculture Production Systems (CAPS)
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Reyes, Manuel R. (2014)
    Forage Legumes are characterized by having seeds in pods with compound leaves and their roots have symbiotic relationship with bacteria which allow nitrogen fixation in the atmosphere. legumes are rich in protein which contain desirable amino acid in their foliage and seeds. Forage legumes were integrated as component in conservation agriculture throughout the wold which provide feed for livestock, as green manure and used as soil conservation measure providing soil cover. Thus, selecting and appropriate forage legume is essential to maximize the benefit of Conservation Production System (CAPS).

  • Varietal trial of Adlai (Coix lacryma-jobi L.) for Conservation Agriculture Production Systems (CAPS)
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Reyes, Manuel R. (2014)
    Conservation Agriculture Production Systems (CAPS) promotes food security while improving input efficiency, protect and improve soil, and its diversity, and sustain crop yields. Adlai is a tropical crop valued for its many uses, cereal for food, feed for animals and beads for making rosaries, necklace and other objects. It also has many medicinal uses, although some claims need scientific evidences. Thus, adlai can be a potential crop to achieve full benefits in CAPS.
  • Varietal trial of cassava (Manihot esculenta Crantz)for Conservation Agriculture Production System
    Mercado, Agustin R. Jr.; Edralin, Don Immanuel A.; Arcinal, Gil A.; Reyes, Manuel R. (Claveria, Misamis Oriental, Philippines, World Agroforestry Center-ICRAF, 2014)
    Cassava (Manihot esculenta Crantz) is considered one of the most important economic crops in the Philippines. However,cassava is no longer a staple food for Filipinos as it is used to be, but it is an important cash crop for upland small and large farmers. It is widely cultivated in many areas in the Philippines thus it is important crop to be integrated into the conservation agriculture production system (CAPS). Nearly all the harvested roots are now processed into dry chips and pellets for export as animal feed, as well as into starch, both for domestic and international use. Major production problems are declining soil fertility,soil erosion and the strong fluctuation of the cassava root prices. Identification of suitable high yielding cassava varieties is equally important in our on CAPS. In the context of CAPS,total above ground biomass is one of the important parameters in selecting appropriate variety. Thus we are evaluating cassava varieties that have high both in root and above ground biomass that can be used as mulch for the subsequent crops.
