The field experiment was conducted at the Organic Farming Unit, MPUAT, Udaipur, India to study response of different types of maize varieties grown under organic farming during kharif seasons of 2015 and 2016. The experiment comprises twelve varieties of different types of maize viz., grain maize, sweet corn, baby corn, popcorn and local maize. Results reveal that variety Misthy of sweet corn recorded significantly higher nitrogen, zinc, iron and protein content in grain at harvest on pooled basis of the both years (1.85 %, 45.19 mg/kg, 49.07 mg/kg and 11.57 %, respectively) as compared to other maize varieties. Variety Madhula of sweet corn recorded significantly highest phosphorus content in grain at harvest on pooled basis (0.37%).Potassium content in grain at harvest on pooled basis was not-significant. Variety PHM-3 of hybrid maize recorded significantly higher total NPK uptake during 2015 and2016 (318.30 kg/ha and 338.12 kg/ha, respectively) as compared to other varieties. Variety Farmer Selection recorded significantly higher available nitrogen in soil during both the years as compared to other maize varieties. Grain variety PM-9 recorded significantly higher available phosphorus, zinc and iron in soil as compared to other varieties. Available potassium and organic carbon of different varieties of maize was found non-significant.
