A field experiment was conducted during kharif season of 2013 to evaluate yield, yield attributes, productivity and nutrient uptake by maize varieties as influenced by dates of sowing. Treatments consisted of five maize varieties (HQPM-1, PEHM-2, Pratap Makka-5, Pratap QPM-1 and BIO- 9637) with three dates of sowing (June 15. June 30 and July 15). The results revealed that except cob girth crop sown on June 30 recorded significantly higher yield attributes, yield, N, P and K uptake by grain and total uptake than June 15 and July 15 sown . crops. June 30 sown crop recorded grain yield (50.87 q ha super(-1)) and biological yield (134.3 q ha super(-1)) significantly higher then June 15 and July 15 sown crops. Among the varieties, BIO-9637 recorded grain yield (51.78 q ha super(-1)), stover yield (85.39 q ha super(-1)) and biological yield (137.18 q h a super(-1)) significantly higher over HQPM-1, PEHM-2, Pratap QPM-1 and Pratap Makka-5. Variety BIO-9637 recorded maximum uptake by grain and total uptake of N. P and K which was significantly superior to PEHM-2 and Pratap Makka-5.
