Abstract

The purpose of research is to known type and exactly density fish to aquatic plant Azolla pinnata growth until to give the IR-64 rice result and the best fish, have done in fish nursery center, Wonocatur, Banguntapan, Bantul, Yogyakarta. Located at 112 m up sea level. Land type is Regosol, daily temperature average 28 ⁰C. The research is field experiment that consist two factors, arranged in Randomized Completely Block Design, with three replicates. The first factor is type of fish (1), of two levels: Tawes fish (1₁) and Nila fish (1₂). The second factor is fish density per meter field sided (K), of three levels: there are no fish (K_O), 1 fish (K ₁), and 2 fishs (K₂).

The result of the research indicated influence between type and density fish to rice result. The Tawes fish with density 1 and 2 fishs per m² field and Nila fish with density 2 fish per m² field lave given the highest rice result. Tawes fish with 2 fishs per m² field more impede Azolla pinnata L. Fish density 2 fishs per m² field have given fish result higer. Fish weight average of 1 fish per m² field  higher than 2 fish per m² field.
