Effect of biofertilizers on growth and yield of China aster

The response of VAM and phosphobacterin on China aster was studied during 1999–2001. Treatments comprised of N and P at 25, 50, 75 and 100% of the recommended dose in combination with full K and/or VAM and/or phosphobacterin. Application of 3/4^th of the recommended dose of N and P in combination with full K+VAM+phosphobacterin proved to be the most effective in increasing the plant height, number of leaves, leaf area, number of branches, flower weight, flower diameter, number of flowers and flower yield.
