Abstract: The present investigation entitled “Study on the performance of China aster [Callistephus chinensis (L.) Nees] CV. Kamini under integrated nutrient management” was undertaken to evaluate the growth and yield of China aster cv. Kamini under different combinations of water soluble fertilizers through fertigation, vermicompost and Arka microbial Consortium during October 2017- April 2018 at Floricultural Research Station, Rajendranagar, Hyderabad. The study was carried out in two experiments, a field and a laboratory experiment. The experiment conducted to study the effect of different treatments of water soluble fertilizers, vermicompost and Arka microbial consortium concluded that the treatment 75% WSF + AMC + VC (T9) recorded significantly increased vegetative parameters like highest plant height at 30 days (9.56 cm), 45 days (16.58 cm), 60 days (37.54cm), 75 days (46.96 cm) and 90 days (57.55 cm) after planting, maximum stem girth at 30 days (3.86 mm), 45 days (6.51 mm), 60 days (10.53 mm), 75 days (11.44 mm) and 90 days (13.12 mm) after planting, highest number of primary branches at 30 Title of the thesis :: days (3.48), 45 days (7.60), 60 days (10.29), 75 days (17.48) and 90 days (26.42) after planting, highest total fresh weight (123.16 g) and total dry weight (41.44 g), plant spread in E-W (28.41) and N-S (26.75) directions at 50% flowering, while the lowest plant height, stem girth, number of branches, total fresh weight, total dry weight and plant spread in E-W and N-S directions at 50% flowering were recorded in the treatment T1 (50% WSF). Based on the results on flower parameters the treatment T9 (75% WSF + AMC + VC) has recorded minimum number of days to first flower bud initiation (61.91days) and 50% flowering (80.67days) while maximum days were recorded in the treatment T1. The treatment T9 has recorded highest values on flower quality parameters like flower diameter (6.36 cm) and stalk length (30.75 cm) while lowest were recorded in T1. Yield parameters like number of flowers per plant (51.40), number of harvestings (5.70), flowering duration (60.56 days), flower field life (18.75 days), weight of hundred flowers (338.54g), flower weight per plot (4.92 kg) and flower yield per hectare (18.80 t/ha) was recorded highest in T9 followed by T8 while the lowest were recorded in T1. In case of physiological parameters like leaf chlorophyll content at 50% flowering and leaf nutrient composition (NPK) at harvest maximum values were recorded in the treatment T9 followed by T8 and minimum in T1. The available nutrients in soil did not differ significantly with respect to nitrogen, phosphorous and potassium at the time of planting. Based on the results obtained from evaluation of post harvest life of cut flowers, flowers collected from the treatment 75% WSF + AMC + VC held in 4% sucrose + 200 ppm Al2(SO4)3 was recorded significantly maximum vase life as evidenced by significantly highest water uptake, TSS, fresh weight, fresh weight change, flower diameter and significantly lowest transpirational loss of water, microbial count and electrolyte leakage over control. As far as the economics is concerned the treatment 75% WSF + AMC + VC recorded maximum net returns and B:C ratio (2.23) followed by T8 (2.01) while minimum net returns and B:C ratio (0.81) was recorded in T1. Among the treatments T9 has shown significant increase in growth, flowering, yield parameters and vase life due to better uptake and utilization of nutrients as well as better translocation of photosynthates as influenced by synergistic effects of fertigation, AMC and vermicompost. Hence this can be recommended to the farmers as it is a cost effective method for the commercial cultivation of China aster.
