dc.description.abstractThe present study entitled “Effect of NPK, Biofertilizers and Biostimulants on growth, flowering, seed yield and quality of China aster (Callistephus chinensis L.) Cv. Arka Kamini” was carried at Floricultural Research Station, (Agricultural Research Institute) Rajendranagar, Hyderabad during November to April 2020- 2021. The experiment was laid out in Completely Randomized Design with three replications and seven treatments viz., T1 - RDF 100 %, T2 - RDF 75 % + Azotobacter + PSB + KSB, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %), T4 - RDF 75 % + Azotobacter + PSB + KSB + Humic acid (0.5 %), T5 - RDF 50 % + Azotobacter + PSB + KSB, T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) and T7 - RDF 50 % + Azotobacter + PSB + KSB + Humic acid (0.5 %). The study revealed that significant differences were recorded in China aster. Among the growth parameters, maximum plant height (8.27, 23.56 and 32.27 cm) at 30, 60 and 90 DAT were noticed in T6 i.e., RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %). Maximum number of branches per plant (6.20 and 23.96) at 30 and 90 DAT was recorded in T7 i.e., RDF 50 % + Azotobacter + PSB + KSB + Humic acid (0.5 %) and (12.22) at 60 DAT was observed in T3- RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) Among different flowering parameters T3- RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded least number of days taken for flower bud initiation (50.64 days), minimum number of days taken for bud opening (18.33 days), minimum number of days for 50 % flowering (60.97 days) and maximum duration of flowering (48.37 days). Among different treatment combinations T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded maximum flower diameter (5.53 cm). Whereas, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded maximum flower longevity on plant (15.22 days), maximum number of flowers per plant (21.98) and maximum flower yield per plant (50.16 g). The application of RDF 75% + Azotobacter + PSB + KSB + Seaweed extract (0.5%) (T3) recorded highest seed yield per flower (0.30 g), seed yield per plant (6.59), number of seeds per gram (484.00 g) and test weight (1.72). Further, maximum germination percentage (90.00 %), seedling length (5.93 cm) and seedling vigour index (534.67) was recorded in T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %). The highest available nitrogen (208.33 kg/ha) phosphorus (57.91 kg/ha) and potassium (162.56 kg/ha) in soil was recorded by the application of RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) (T3) The data on the economics of effect of NPK, Biofertilizers and Biostimulants on China aster revealed that, T3 - RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) recorded the highest benefit cost ratio (2.37) over other treatments. It can be concluded that, T6 - RDF 50 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) proved to be the best treatment compared to other treatments to improve plant height, flower quality and yield parameters and seed quality parameters of China aster. While, T3 i.e., RDF 75 % + Azotobacter + PSB + KSB + Seaweed extract (0.5 %) was found to be the best treatment to improve flowering parameters, seed parameters and soil nutrient status of China asteren_US
