A study effects of organic humic fertilizers on yield and Some important features maize genotypes in Ardabil region

The aim of organic farming and produce a healthy product full of healthy food so that the use of pesticides and chemical fertilizers in place to minimize the use of pesticides, herbicides and pesticides used biological methods. In order to study the response of maize genotypes to use two types of liquid humic fertilizer based Peat and leonardite, were conducted a experiment split plot on the basis of completely randomized block design in three replicated in Agricultural Research Station of Islamic Azad University, Ardabil branch in 2010. In this experiment main-plots contain of two conditions (with the application of humic fertilizer; without the application of humic fertilizer) and the sub-plots were contain of three maize genotypes. Results showed that between experimental conditions view of the all character’s there are significant differences in 1 percent probability level. There was also a significant difference found between studied cultivars on the all character’s there are significant differences in 1 percent probability level. Results from mean comparison of data for experimental conditions (experimental solution) being studied showed that the all characteristics on the best conditions of leonardite based liquid humic fertilizer. Simple correlations between different traits showed that the yield per plant leonardite application with 1000 grain and hectoliter weight and there was a significant positive relationship. The relationship between 1000 grain weight and hectoliter weight was completely positive.
