Abstract:The present investigation entitled “Standardization of different concentrations of plant growth regulators and levels of nitrogen, phosphorus on growth, flowering, yield and quality of China Aster (
Callistephus chinensis (L.) Nees) under Chhattisgarh conditions” was conducted at the Horticultural Research cum Instructional Farm, Department of Floriculture and Landscape Architecture, College of Agriculture, IGKV, Raipur (C.G.).The Experiment-II entitled “Effect on different levels of nitrogen and phosphorus on growth, flowering, yield and quality of China Aster” was conducted during winter season of 2018-19 and 2019-20. The experiment was conducted in Factorial Randomized Block Design with 24 treatments” comprising of two varieties
viz. Arka Shashank and Arka Archana as factor A and four levels of Nitrogen,
i.e, (120, 140, 160, 180 kg/ha), and three levels of Phosphorus (100, 120, 140 kg/ha) as factor B. The doses of Nitrogen and Phosphorus were applied in two splits with constant dose of potassium (60kg/ha) were applied in the field.
Plants have to be exposed to proper climatic factors in order to get optimum and economic flower yields. Therefore, under transitional Chhattisgarh plains, there is a need to standardize production technology involving systematic research to evaluate acceptable variety, standardize fertilizer levels on growth, flowering, yield and quality of China aster flower production under the Chhattisgarh plains.
