The widely distributed water fern Azolla was investigated for use as an amendment in the bioremediation of fuel-contaminated environments. In a field experiment Azolla pinnata as well as Pistia stratiotes and Salvinia molesta were applied to plots containing soil that had been surface-contaminated with diesel fuel (2.4 L m(-2)) and flooded with water. The plants quickly died and bacterial flocs...

The present study was carried out to examine 6 plants including aquatic and terrestrial plants on food preference and growth of grass carp. 7 experimental treatments with three replicates were considered. The experimental treatments were ponds containing T1: M. spicatum, T2: C. demersum, T3: A. filiculoides, T4: L. minor, T5: C. dactylon, T6: M. sativa and T7: M. Spicatum + C. demersum + A. fil...

The rapidly growing water fern Azolla, which contains a nitrogen-fixing blue-green algal symbiont, has been studied as a possible system for photoproduction of molecular hydrogen. When this plant is grown on a combined nitrogen supply, photochemically generated hydrogen can be diverted through the algal nitrogenase system, which serves as a source of molecular hydrogen generated from water. Thi...

As a staple in Indonesian diet, rice demand increase along with the population growth. Therefore, order to fulfill continuous increase, researches were conducted land productivity. The of growth and productivity upland application Azospirillum sp. Azotobacter compost, Azolla, bran carrier studied. Nitrogen fixer applied as biofertiliser mean supply available nitrogen for This research was Cipar...

A pot experiment was conducted on Satla soil series in Terokhada Upazilla, Khulna during the boro season (February to June) see whether Azolla (biofertilizer) could be grown together with BRRI dhan 28 and compare effect of recommended dose N (100 kg ha-1) that different combinations urea (all treatments having doses P, K, S Zn). The laid out a completely randomized design 5 4 replications. pinn...

Azolla mycrophylla, Cherry leaves and tea waste are organic materials that have potential as liquid fertilizers because they able to bind nitrogen from the air contain high potassium. In manufacture of fertilizers, bioactivators such bamboo shoots needed accelerate fermentation process. The purpose this study was determine content N, P, K elements sensory tests on fertilizer (POC) combining myc...

Azolla is an aquatic plant that has the potential to be used as animal feed due its high nutritive value and very productive plant. Thus, objectives of this study are determine compare nutrient mineral composition pinnata microphylla. A. microphylla plants have a introduced new alternative supplement ruminants. Samples were collected at Ladang Lembah Kaprima Hulu Seladang, Tenox Agribusiness (M...

Nitrogenase activity was measured in leaves along the main stem axes of Azolla pinnata R. Br. The activity was negligible in leaves of the apical region, rapidly increased to a maximum as leaves matured, and declined in aging leaves. In situ absorption and fluorescence emission spectra were obtained for individual vegetative cells and heterocysts in filaments of the A. pinnata and Azolla caroli...
