in order to evaluate the yield and yield components of rice (oryza sativa l. cv. tarom hashemi) in integrated rice, duck and azolla, an experiment was conducted at the research farm of sari university of agricultural sciences and natural resources during 2012. experiment was arranged in split plot based on a randomized complete block design with three replications. the number of ducks as main p...

the genus azolla forms a group of small-leafed, floating aquatic ferns native to the tropics, subtropics, and warm temperate regions of africa, asia, and america. for several decades, these ferns have been utilized for various purposes: e.g. as green manure, feed for animals, but also for the removal of different metals (e.g. hg, pb, cr and cd) through wastewater treatment or for elimination of...

Background & Aims of the Study: The 2, 4, 6-Trichlorophenol (TCP) is a phenolic compound which it can produce adverse effects on human and environment. Therefore, the removal of these compounds is necessary. The aim of this study is the investigation of TCP removal by using Azolla filiculoides biomass. Materials & Methods: The Azolla biomass was dried in the sunlight, and...

Zinnia is an annual plant with the long flowering period from late spring to mid-autumn. It is a popular plant for landscape. In the present study, the effect of two types of growth promoting bacteria and Azolla compost on some ornamental characteristics of Zinnia were evaluated in pot cultivation and greenhouse conditions. The factorial experiment was conducted in three replications based on a...

This study was focused on removal of various parameters in paper mill effluent using a method called bioremediation by Azolla caroliniana.  The experimental investigations have been carried out using Azolla caroliniana for conducting the sorption study with various dilution ratios (2, 4, 6, 8, and 10), pH (3, 4, 5, 6, 7, 8 and 9) and biomass (200, 400, 600, 800 and 1000 g). Th...

Sustainable agriculture demands reduced input of man-made nitrogen (N) fertilizer, yet N2 fixation limits the productivity of crops with heterotrophic diazotrophic bacterial symbionts. We investigated floating ferns from the genus Azolla that host phototrophic diazotrophic Nostoc azollae in leaf pockets and belong to the fastest growing plants. Experimental production reported here demonstrated...

AIM The present study was conducted to see the effect of feeding different levels of Azolla meal on blood biochemicals, hematology and immunocompetence traits of Chabro chicken. MATERIALS AND METHODS The study was conducted on 160 Chabro chicks, which were randomly divided into four treatment groups each with four replicates of 10 birds. The first treatment (T1) served as a control in which b...

background: one of the most important environmental pollutants is industrial wastewaters. discharging of colorful industrial effluents to receptive waters can lead to eutrification and it has the carcinogenic and mutagenic properties. therefore, the aim of this study is evaluation of acid blue 15 dye removal by dried azolla from aqueous solution. material and methods: the azolla biomass was dri...

A study was undertaken to evaluate the nutritive value and digestibility of Azolla in ruminants by in vitro techniques. The crude protein, crude fibre and ether extract contents were at a level of 21.37%, 12.5% and 2.3%, respectively. The neutral and acid detergent fibre levels were about 35.4 and 23.9%, respectively. The average in vitro dry matter digestibility, in vitro organic matter digest...
