Abstract:
China Aster (Callistephus chinensis (L.) NEES.) was a hardy winter annual, originated in China and belongs to plants family Asteraceae was one of the commercially cultivated flowering annual. China Aster can be used as cut flower, potted plant and as flowering borders in landscape gardening. Despite of its importance the productivity of the flowers was not upto the mark and to reach the needs very high doses of chemical fertilizers has to be used. Due to high usage of inorganic fertilizers the soil properties are deteriorated greatly and to mitigate this negative effect an experiment was conducted to know the best combination of Inorganic fertilizers with Biofertilizers which were known to have a positive effect on nutrient uptake when contacted with rhizosphere. Different combinations of Recommended Dose of (RDF) with Biofertilizers [Azospirillum, Potassium Mobilizing Bacteria (KMB) and Phosphate Solubilizing Bacteria (KMB)] were analysed in the Variety Arka Kamini at Coastal region of Andhra Pradesh. The experimental results revealed that all the vegetative parameters except plant height was superior in the plants those received 100% RDF with Azospirillum @ 4 kg acre^-1 + PSB @ 4 kg acre^-1 + KMB @ 4 kg acre^-1. The quality of the flowers was greater when the plants received 120% RDF with same dose of Biofertilizer but, the yield was more when 100% RDF was given with each biofertilizer @ @ 4 kg per acre.
