Abstract:
The present study entitled “Effect of different dose of chemical fertilizer with different formulation of bio- fertilizer to the growth and flower yield of China aster(Callistephus chinensis (L.) Nees) var. Arka Archana” was carried out to study the effect of integrated nutrient management on growth parameters of China aster. The experiment comprises thirteen treatment combinations i.e. 100%, 75%, and 50% RDF along with vermicompost and different formulations of biofertilizer (Azotobecter + PSB). Observations on various growth, parameters viz., plant height at 45 DAT, 75 DAT, 105 DAT, plant spread at 45 DAT, 75 DAT, 105 DAT, number of primary branches plant ^-1 at 45 DAT, 75 DAT, 105 DAT and stem girth were recorded. In the present investigation the maximum value for plant height at 45 DAT, 75 DAT, 105 DAT, plant spread at 45 DAT, 75 DAT, 105 DAT, number of primary branches plant ^-1 at 45 DAT, 75 DAT, 105 DAT and stem girth were found in treatment T₄ (75% RDF +VC + Azotobacter +PSB) and the minimum value for plant height, plant spread, and stem girth was observed in treatment getting 50% RDF + VC + liquid PSB (T₁₁) moreover, in number of primary branches the lower value was observed in treatment T₁₂ (50% RDF + VC + liquid Azotobacter).
