    Agroforestry and sustainable vegetable production in South East Asia watershed project: Indonesian TMPEGS
    Susila, Anas D. (2008)
    In East and Southeast Asia (SEA) about 1.7 billion pesons are living on less than US$i/day. This project will seek to alleviate poverty, food scarcity,a nd reduce environmental degradation in SEA by combining economically viable and resource-conserving technologies, and gender friendly socio-economic policies that will benefit and reward stakeholders in a watershed, especially small-scale farmers both women and men (SSFWM). The hypothesis to be tested is integrating vegetable production in the agro-forestry system biodiversity in SEA watersheds and vice-versa. It has objectives on SANREM Technology, Marketing, Policy, Environmental and socio-economic impacts, Gender and Scaling-up (TMPEGS). A team of 28 scientists from several prestigious U.S. and SEA universities, including the world agro-forestry (ICRAF) and the world vegetable (AVRDC) centers, and MARS Incorporated have formed a robust partnership to serve the poor in SEA.

  • 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.

    Collection and characterization of indigenous vegetables obtained from Bogor and Pandeglang districts
    Laksana, A.; Purwoko, Bambang S.; Syukur, M.; Susila, Anas D.; Palada, Manuel C. (2008)
    Research was conducted to collect and characterize several indigenous vegetable species obtained from Bogor and Pandeglang districts. Differences among accessions and their lineage were also studied. A randomized block design with three replicates was used during planting of each species. Accessions were collected from Nanggung, Parung, Tamansari, Cibinong (Bogor District), and Pandeglang, Mandalawangi, Cadasari, and Cimanuk (Pandeglang District). They consisted of nine kemangi (Ocimum americanum L.) accessions, 11 katuk (Sauropus androgynus (L.) Merril) accessions, 10 honje (Etlingera giseke) accessions, and eight kucai (Allium tuberosum Rottler ex Sprengel) accessions.

    Drip irrigation: Will it increase yield in traditional vegetable production system?
    Susila, Anas D.; Prasetyo, Tisna P. (2008)
    In the rain-fed production system area, vegetables normally can be grown on wet season (>200 mm/month) between December - April. During dry season ( Drip irrigation systems have the highest potential water application efficiency of the irrigation system used in commercial vegetables production. Field studies have shown a significant decrease in irrigation requirements of tomatoes with the use of drip irrigation system and compared to sub-irrigation system. Marketable yield, fruit size, and fruit quality were comparable and some cases better with the use of drip irrigation than sub-irrigation (Pitts and Clark, 1991). Drip irrigation is a tool to reduce water use, increase fertilizer efficiency, and improve profit, while simultaneously reducing the potential risk to the environment due to enrichment of surface and ground water (Hochmuth, 1992). This research was conducted to evaluate the effect of Low Cost Drip Irrigation System on the yield of Amaranth (Amaranthus sp), Kangkong (Ipomoea reptans), Yard Long Bean (Vigna unguilata), Green Bean (Phaseolus vulgaris), and Katuk (Sauropus androgenous) growth and yield during wet season.

    Environmental friendliness fertilizer recommendation: Phosphorous calibration for yard long bean production in ultisol
    Susila, Anas D.; Kartika, Juang Gema; Prasetyo, Tisna P.; Palada, Manuel C. (2008)
    The basic purpose of soil fertility evaluation is to provide information on the nutrient status of the soil and predict the relative response to added nutrient. The Crop Nutrient Requirement (CNR) values are those amounts of nutrients needed to produce optimum, economic yields from a fertilization standpoint. It is important to remember that these nutrient amounts are supplied to the crop from both soil and fertilizer. The amounts are applied as fertilizer only when a properly calibrated soil test indicates very small extractable amounts of these nutrients to be present in the soil.

    Fertilizer Recommendation: Correlation and Calibration Study of Soil P Test for Yard Long Bean (Vigna unguilata L) on Ultisols in Nanggung-Bogor
    Susila, Anas D.; Kartika, Juang Gema; Prasetyo, Tisna P.; Palada, Manuel C. (2010)
    Proper fertilization of a crop is knowing the crop nutrient requirement for production of maximum yield and the potential level of nutrient availability from the soil. In addition to yield obtained, quality of the commodity is an important factor of profit and shelf-life for high-value crops. Nitrogen, phosphorous, and potassium availability are the most limiting factors for maximum growth and yield. Yard Long Bean (Vigna unguilata L.) were grown to evaluate optimum rate of N, P, and K fertilizer in Ultisol Jasinga soil with low pH (5.5), low C-Organic (1.54%), very low N-total (0.12 %), low K content (0.29 me/100 g), but very high soil P2O5 concentration (19.2 ppm) to evaluate the best crop management practices with starter solution.

    Findings and challenges: Can vegetables be productive under tree shade management in West Java?
    Manurung, Gerhard; Susila, Anas D.; Roshetko, James M.; Palada, Manuel C. (Blacksburg, VA: Office of International Research, Education, and Development, Virginia Tech, 2008)
    Farmers in Nanggung, West Java traditionally cultivate vegetables under full sunlight. There is opportunity to expand vegetable production in the understory of agroforestry system, but farmers have limited experience with such practices. An on-farm trial was implemented to evaluate the production of 11 commercial vegetable species under three levels of tree shading in a nested design, replicated 3 times. The species included in the trial were honje (Etlingera elatior), terubuk (Saccharum edule), katuk (Sauropus androgynus (L.) Merrill), kenikir (Cosmos caudatus Kunth), kangkong (Ipomoea aquatica Forsskal), amaranth (Amaranthus sp.), chili (Capsicum annuum L.), eggplant (Solanum melongena L.), long bean (Vigna unguiculata (L.) Walp.), green bean (Phaseolus vulgaris L.) and tomato (Lycopersicon esculentum Miller). Twenty-five independent variables were analyzed for their effect on vegetable survival, growth and yield. Average light levels for each treatment were 482-540 *1000 lux (open area, control), 43-540 *1000 lux (medium light) and 32-174 *1000 lux (low light). Preliminary results indicate that vegetable production under dudukuhan (agroforestry) systems shade is a viable option for smallholder farmers, however more intensive species-specific and site-specific management is required. A program of training and extension support would help smallholders develop such deliberate management practices.
