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...

Purpose: To assess the potential of Azolla filiculoides, total body collected from a rice farm in northern Iran as source for biodiesel production. Methods: Solvent extraction using Soxhlet apparatus with chloroform-methanol (2:1 v/v) solvent blend was used to obtain crude oil from freeze-dried the Azolla plant. Acid-catalyzed transesterification was used to convert fatty acids (FA), monoglycer...

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...

background and purpose: the 2-chlorophenol (2-cp) and 4-chlorophenol (4-cp) are phenolic compounds which may have adverse effects on human and environment. therefore, removing these compounds from water and wastewater is necessary. this study aims to analyze 2-cp and 4-cp removal by using azolla filiculoides biomass. materials & methods: azolla biomass was sun dried, crushed and sieved to parti...

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...

Attempts to increase food crop yields by intensifying agricultural systems using high inputs of nonrenewable resources and chemicals frequently lead to de-gradation of natural resources, whereas most technological innovations are not accessible for smallholders that represent the majority of farmers world wide. Alternatively, cocultures consisting of assemblages of plant and animal species can ...

The occurrence and ultrastructure of bacteria in leaf cavities of symbiotic Azolla caroliniana were examined by transmission electron microscopy. Bacteria were observed in all leaf cavities of Azolla cultures. Five ultrastructurally distinct types of bacteria were observed in each individual leaf cavity. Features used to characterize the bacteria included morphology, cell wall structure, and cy...

The use of constructed wetlands for purifying pre-treated wastewater is a cost effective technology that has been found to be more appropriate for many developing countries. The technology is also environmentally friendly with the wetlands being habitats for many water birds and other aquatic organisms. This study assessed nutrient removal efficiency of two floating macrophytes (Lemna minor...

Aquaculture is identified as the viable alternative source, for increasing fish production to meet out ever growing demand consumption. Due their high nutritive value, toxic-free, environment friendly and productivity Azolla Spirulina were considered promising feed. The knowledge of hematological growth characteristics an important tool that can be used a sensitive effective index monitor patho...
