The field experiment was conducted at Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai Nagar, Tamil Nadu during July – October 2015 to study the effect of mycorrhizal inoculation (VAM) and different levels of phosphorus on yield, quality, nutrient uptake and post harvest nutrient status of hybrid sunflower cv. sunbred.The experiment was conducted by factorial randomized block design with two replications. The treatments consisted of 4 levels of P2O5 (0,25,50,75 and 100kg/ha) applied in the presence or absence of VAM inoculates. The results of experiment revealed that mycorhizal inoculated plants produced maximum seed and stalk yield, oil content, oil yield, protein content, nutrient uptake than non mycorhizal inoculation, nutrient availability were maximum in non mycorhizal inoculation. Among the various phosphorus levels tried, P2O5 at 100 kg ha-1 recorded maximum values for yield, quality, nutrient uptake while P2O5at 25kgha-1 registered maximum NPK availability over other levels. With regard to interaction effect, mycorrhizal inoculation with P2O5 @ 100 kg ha-1 recorded maximum values for yield, quality and nutrient uptake of sunflower but it was on par with mycorrhizal inoculation with P2O5 @ 75 kg ha-1. Non-mycorrhizal inoculation with P2O5 @ 25 kg ha-1 recorded maximum values for post harvest nutrient status of Sunflower. Lowest values of yield, quality and nutrient uptake were recorded by non-mycorrhizal inoculation with P2O5 @ 25 kg ha-1. Mycorrhizal inoculation with P2O5 @ 100 kg ha-1 recorded minimum values for post harvest nutrient status of Sunflower.
