African marigold is one of the medical plants which was native to South America especially Mexico and belongs to the family Asteraceae (Compositae). Like other crops the flowering plant also has different response to different rate organic manures and inorganic fertilizers as well as bio fertilizers, N12 P80 K40/ha has an effect on early flowering of marigold and the flowering stem height was affected significantly by the application of NPK fertilization, poultry manure give better yield as compared to other organic manures. Physiological parameters of marigold were greatly increased by the use of NPK fertilizer and bacterial inoculation (Table 1 and 2). Application of bio-fertilizer significantly improved quality and quantity features in marigold, both NPK and bio fertilizers have a significant effect on morphological traits and effect NPK on P & K traits of marigold (Table 3 and 4), the yield and economics of marigold as influenced by various treatments of treatments of organic fertilizers (Table 5). Azotobacter is the free living nitrogen fixing bacteria which fix the nitrogen equivalent to 30-40 kg ha-1. Organic manure has a role in improving the soil chemical as well as physical properties of soil. The role of bio-fertilizers containing symbiotic or non-symbiotic nitrogen-fixing bacteria in augmenting vegetative growth characters, yield and yield components, essential oil productivity and/or chemical composition (including chlorophyll a, b and carotenoids and/or N, P and K leaf percent and content.
