A field experiment was conducted during kharif 2006 and 2007 at G. B. Pant University of Agriculture and Technology, Pantnagar to study the effect of nitrogen stress on productivity and profitability of pop, composite and hybrid corns in Mollisols of Uttarakhand. Significantly higher productivity and profitability was observed at 80 kg than 60 and 40 kg nitrogen application mainly because of better plant growth and yield attributes. Among the maize cultivars, ‘Him- 129’ (hybrid) proved more productive and profitable than pop corn ‘VL Amber’ and composites ‘Pragati’ and ‘Vivek-11’.
