An experiment was conducted during kharif season of two consecutive years 2013 and 2014 at the Instructional Farm, Rajasthan College of Agriculture, MPUAT, Udaipur to evaluate the effect of sowing dates and foliar spray of urea on yield attributes and yield of maize cultivars. The experiment was conducted with two sowing dates with four cultivar (Pratap HQPM – 1, Bio – 9637, Pratap Makka – 3 and Pratap Makka – 5) and three foliar spray (2 % urea, 4 % urea and water spray). The experiment conducted in Split Plot Design (SPD) with three replications. The results showed that 25th June sown maize recorded significantly higher yield attributing characters viz. cobs plant-1, grains cob-1 and 1000 grains weight as compared to 15th July sown maize. 25th June sown maize also gave significantly higher grain yield (4819 kg ha-1), stover yield (8733 kg ha-1), biological yield (13552 kg ha-1) as compared to 15th July sown maize. Amongst the cultivars of maize, Pratap HQPM–1 gave highest cob length, cob girth, grains cob-1, grains row cob-1, 1000 grains weight, grain yield (5098 kg ha-1) and harvest index (39.86 %). Whereas, Pratap Makka – 3 gave maximum stover yield (9009 kg ha-1) as compared to other maize cultivars. Foliar spray of 4 % urea gave significantly higher 1000 grains weight and grain yield (4739 kg ha-1) as compared to 2 % foliar spray of urea and water spray. Application of 4 % urea also gave significantly grains cob-1, stover yield (8668 kg ha-1) and biological yield (13407 kg ha-1) as compared to water spray but found at par with 2 % foliar spray of urea.
