THE EFFECTIVENESS OF PADDY FIELD MUD ON CULTIVATION OF AZOLLA PINNATA AS A HIGH PROTEIN FORAGE

Abstract

Aquatic macrophytes, such as Azolla pinnata has a wide range of adaptation in growth and fast yield time. This plant has high nitrogen fixation ability and potency as high protein forage. The aim of this research was to measure production potency and protein content on several media. This research was designed using factorial completely randomized design with two factors. Factor A was paddy field mud 10% andfactor B was media (control, hoagland, andhyponex 0.1%). The measured parameter were dissolved N absorption, doubling time cover area, biomass production, and protein content. Data were analyzed using ANOVA and the results showed that Azolla pinnata has high dissolved N absorption (≥ 97.51%). Additional ofpaddy field mud and kinds of media treatments significantly shortened doubling time cover area, biomass production, and protein content compared with control (without paddy field mud) (p< 0.05).
