A field experiment was conducted at the MARS, UAS, Dharwad to study the integrated nutrient management in popcorn (Zea mays var. everata) during kharif 2018. The experiment was laid out in split -plot design with three replications consisting of four organic levels as main plot ( O1: FYM @ 5 t ha-1, O2: FYM @ 7.5 t ha-1, O3 : VC @ 1.25 t ha-1 and O4 : VC @ 2.5 t ha-1) and three fertilizer levels as sub plot (F1: 75 % RDF, F2: 100 % RDF and F3: 125 % RDF) along with one absolute control. The experimental results revealed that, application of VC @ 2.5 t ha-1 recorded significantly higher total dry matter accumulation (205.91 g plant-1) at harvest and grain yield (3,541kg ha-1)and found at par with application of FYM @ 7.5 t ha-1 (205.91 g plant-1 and 3,494 kg ha-1, respectively) compared to other organic levels. Among fertilizer levels, application of 125 % RDF recorded significantly higher total dry matter accumulation (207.20 g plant-1) at harvest and grain yield (3,619 ha-1)over other levels. Interaction effect indicated that application of VC @ 2.5 t ha-1 + 125 % RDF recorded significantly higher total dry matter accumulation (219.20 g plant-1) at harvest and grain yield (4,003 kg ha-1) and found at par with application of FYM @ 7.5 t ha-1 + 125 % RDF (216.63 g plant-1 and3,983 kg ha-1, respectively). Absolute control recorded significantly lowest total dry matter accumulation ( 144 g plant-1) and grain yield ( 1,378 kg ha-1) compared to rest of the treatment combinations.
