Effect of cyanopith and cyanospray biofertilizer on Amaranthus Dubius

A study was conducted in the Model Organic Form, Department of Marine Biotechnology, National Facility for Marine Cyanobacteria, Bharathidasan University, Trichirappalli-620024, Tamilnadu, India, during 2010. Agriculture in India has been a major component of the Indian economy. Biofertilizers are microbial inoculants containing live or latent cells of efficient nitrogen fixing or nutrient mobilizing microorganisms from the environment. Biofertilizers can provide to the small and marginal farmers economically viable weapon to attain the ultimate goal of increasing crop productivity. This study was carried out to utilize the available lignocellulosic waste of coir pith for it's conversion into biofertilizer by cyanobacteria and to analyze the growth promoting ability of cyanopith as basal and cyanospray as foliar fertilizer on Amaranthus dubius.
