Azolla pinnata var. pinnata R. Brown, a heat tolerant (up to
41° C air and 42.5° C water temperature at 0.5 cm depth)
native aquatic fern was grown in ponds (by foliar spray of 10
kg TSP and 5 kg MP in a solution/ha/day) without nitrogen
input and harvested about 10% crop every day which was on
an average 1 ton/ha/day with full sun-shine) round a year in
tropical Bangladesh. Lowest yield (>800 kg/ha/day) obtained
during spring has been attributed to low humidity (50-67%) and
lower sun-shine, and highest (1200 kg/day/ha) in late summer
with high humidity (>70%). Cost of production was about 12
US$/ton fresh Azolla/ha/day which was sold at about 25 US$.
The net income over fish production was estimated to be about
1,800 US$. The low investment and good return every day was
lucrative and cost effective. The organism has symbiotic N2
fixer Anabaena azollae that fixes about 600 kg N/ha/year like
that of Rhizobia in legumes and contains about 3.5% N, rich in
anthocyanin pigment, etc. These features made the organism
an excellent feed for fish (production increased over 20%) and
poultry (2% sun-dried Azolla granules as food supplement
resultedbetterhealthandincreasedeggproductionby45%),use
as compost or as biofertilizer (Azolla as dual crop and pounding
in to the soil before tiller and flower initiations) and rawmaterial
forbiogasproduction.Integratedfarmingwith Azollapinnata var.
pinnata could increase productivity, keeping clean environment.
