Impact of Bio-fertilizers and Inorganic Manures on Flower Yield Attributes of China Aster (Callistephus chinensis L. Nees) cv. Kamini

The impact of bio-fertilizers and inorganic manures on China aster was studied during 2019-2020 at Horticultural Research Farm, Department of floriculture and Landscape Architecture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G) in Rabi period. The China aster has become one of the most popular garden flowers. Among the colours present in all of the many variations are pure white, purple, dark blue, numerous shades of pink, pastel blue, and red.Treatments comprised of 50, 75 and 100% of the recommended dose in combination with bio-fertilizers Azotobacter, Vermicompost, PSB and FYM proved to be the most effective in increasing the weight of individual flower (g), flower yield per plant (g), flower yield per plot (kg) and flower yield per hectare (q). Flower yield per plant recorded significant variations among the different treatments, the maximum flower yield (39.36g) per plant was obtained in treatment T9 (75%RDF +25% Vermicompost +PSB + Azotobacter) which exhibited similar result with the treatment T8 (75% RDF + 25% FYM + PSB +Azotobacter).
