From 2003-2006, 34 research projects were carried out at CelAgrid with the financial support from Swedish International Development Authority (Sida)/Swedish Agency for Research Cooperation (SAREC) through MEKARN for Research Cooperation for Livestock-based Sustainable Agriculture in the Lower Mekong Basin, Cambodian Agricultural Research Fund (CARF), International Foundation for Sciences and Centro International para Agricultura Tropical and articles were published in various local and international journals (see publications). However, 24 main topics with 40 experiments are going and need to be carried during 2007-2009. The topics of these experiments are listed below:

1. Effect of different levels of mixture of water spinach and fresh water hyacinth leaves on pigs growth  performance

2. Effect of different fiber sources as feed supplements to based diets of water spinach (Ipomea aquatica) on growing rabbits

3. Evaluation of different ratios of manure and water plants on the production of earthworms, and the  effect of management system and supplementation of earthworms and water spinach on the survival rate, growth performance and productivity of local chicks and hens.
        a. Experiment 1: Effect of mixing cow manure and water plants on earthworm yield and humus production
        b. Experiment 2: Effect of management system and supplementation of earthworms and water spinach on the survival rate, growth performance  and productivity of local chicks and hens.

            esculenta) leaves as replacement for fish meal
        b. Experiment 2: Effect of ensiled taro (Colocasia esculenta) leaves as replacement for fish meal on growing pig

12. Effect of chopping and wilting fresh cassava leaves on their value as protein sources for growing pigs
        a. Experiment 1: Effect of chopping and wilting cassava leaves on HCN content
        b. Experiment 2: Effect of chopping and wilting cassava leaves on intake, digestibility and N
            retention by growing pigs

        d. Experiment 4: Adoption by farmers of the use of cassava leaves to improve the protein mineral and vitamin status of rice byproducts traditionally used for feeding pigs

13. Effect of nitrogen fertilization on Taro (Colocasia esculenta) yield and the use of Taro forage for pigs.
        a. Experiment 1: Effect of N levels of effluent from biodigester loaded pig or cow manures on the
            biomass yield of Taro
        b. Experiment 2: Effect of taro (Colocasia esculenta) leaves sun-wilted or silage fed with three sources of carbohydrate on nutrients digestibility of crossbred pigs

14. Effect of harvest interval on biomass yield of mulberry
