Maize (Zea mays L.) is an important grain as well as fodder crop. A study was conducted to assess the effect of planting date on different maize hybrid at College of Agriculture, University of Sargodha, Pakistan during the year 2014 and 2015. The experiment was designed with randomized complete block design (RCBD) with split plot arrangement keeping sowing dates (25th Feb, 6th Mar and 14th Mar) in main plots and maize hybrids i.e. (DK-6142, DK-6525 and DK-9108) hybrids in sub plots having three replications. The R×R and P×P distance was maintained 75 cm and 20 cm respectively. The crop was sown manually in ridges. The crop was sown with seed rate of 10 kg ha-1. Seed were treated with “Confidor”. All other management practices were kept normal. Recorded data was shown that all the maize hybrids differed significantly in case of yield components with mean values. i.e. plant height (145.86 cm), number of cobs per plant (1.45 cob), no. of grains per cob (425.67), grains rows per cob (31.67), 1000- grains weight (272.55 g), biological yield (12831 kg-1), grain yield (4069.4 kg ha-1) and Harvesting index (31.53%). It may be concluded from this study that sowing date (25th Feb) and Maize hybrid (DK-6142) is recommended for achieving high yield under semi-arid conditions of Sargodha.
