Islam A.B.M.S. | Haque M.Z.
Six selected strains of azolla were studied in Bangladesh Rice Research Inst. field under shade and without shaded condition. For biomass production a single strain was studied with and without phosphate application at different water depths. Rate of biomass production of azolla varied among different strains and from one season to another. Under shaded condition biomass production was far better than without shade. Maximum biomass production of 43 kg dry matter/ha/day was recorded under shaded condition that corresponds to 1.16 kg N/ha/day.
