Abstract

In order to study Kadostim fertilizer on maize cultivars, experimental form of split plot randomized based complete block design with three replications in agricultural land khanghah sofla was located in the Namin city in 2011. The main factor included two conditions (kadostim fertilizer; without the application of kadostim fertilizer) and the sub factor included 3 maize genotypes (ZP677, Golden west, OS499).  Considering the ANOVA results in studied traits, it was observed that there is a significant difference between harvest index and grain yield at probability level of 1% and between 1000 grain weight at probability level of 5% in experimental conditions. Results to data mean comparison on studied genotypes indicated that based on grain yield among the studied genotypes, Golden West with a mean of 6.77 ton per hectare was the best genotype and OS 499 genotype with a mean of 5.29 ton per hectare was the lowest studied genotype. Also Results to data mean comparison in experimental conditions suggested that applying kadostim fertilizer had good effects on studied traits.
