In this experiment the VAM fungi viz., GlomusGlomus fasciculatum, fasciculatum, G. mosseae, G. intraradices with an un-inoculated control was maintainedG. mosseae,G. intraradices. and three P levels viz., 60, 90, 120 kg ha-1 were tried. The results brought out that xanthophyll yield was positively and significantly correlated with plant height (r =Article Info +0.964), number of secondary branches (r = +0.949), total dry matter production (r = +0.958), leaf area (r = +0.958), LAD (r = +0.958), NAR (r = +0.957), CGR (r = +0.872),Accepted: flower size (r = +0.839), number of flowers per plant (r = +0.954), flower yield per hectare26 April 2017 (r = +0.952), petal meal yield per hectare (r = +0.982), N uptake per hectare (r = +0.908),Available Online: P-uptake per hectare (r = +0.919) and xanthophyll content per kg of petal meal (r =10 May 2017 +0.964). Introduction Marigold (Tagetes erecta L.) belongs to contain high quality of essential oil that can Asteraceae family and is a herbaceous plant be used for scenting soaps, perfumery, with aromatic, pinnately divided leaves and is cosmetic, and pharmaceutical industries. usually used as a bedding plant, cut flower, or Considering its importance as commercial as a coloring agent in poultry feed to obtain flower crop, the study on effect of VAM fungi yellow egg yolks (Dole and Wilkins, 2005). on the growth, yield and xanthophyll content T. erecta L. has smaller flowers and leaves of marigold, at different phosphorus levels than those of most other marigolds. The was initiated. plants brighten up any sunny area in the landscape and attract attention.
