A field experiment was conducted during 2019 to 2020 at Dehradun, to study the effect of integrated nutrient management on productivity of maize (Zea mays L.) in doon valley region. The experiment was laid out in a randomized block design (RBD) in successive crop with 3 replications, consisting of 9 different treatments and the variety K-25. The results revealed that 50% RDF + 50% organic manure + zinc sulphate noticed significantly higher grain yield (3280.67 kg/ha) over control and 100% recommended dose of fertilizer through chemical fertilizers (150:60:40 kg/ha) alone was found on par with rest of the treatments. Next best treatment was 75% RDF + 25% organic manure which recorded significantly higher grain yield (3110 kg/ha) over treatment with control. The combined application of 50% recommended dose of fertilizer + 50% organic manure + zinc sulphate showed higher significance in harvest index (23.88).
