In order to study the effect of different amounts of manure on yield of hybrid maize cultivars under climatic conditions of Kermanshah province, a split plot experiment based on randomized complete block design with three replications in 2011-2012. It was implemented at Mahidasht Agricultural Research Center in Kermanshah. The studied factors included maize cultivars (Single Cross 704, Simon, NS) as the main factor and different levels of livestock manure at four levels (0, 10, 20 and 30 ton / ha) in sub plots. The results of analysis of variance showed that the effect of manure on the studied traits was significant. Comparison of mean data showed that biological yield and grain yield of the studied hybrids increased significantly with increasing level of manure. The highest increase in yield was related to 30 ton / ha manure and Simon hybrid treatment.
