The study of effect of two types of liquid Humic fertilizer on dry matter in maize SC variety

Humic acids (HA) are a major component of organic fertilizers. In order to study the response of maize genotype against the application of peat and leonardite based liquid humic fertilizers, an experiment was conducted at experimental field of Islamic Azad University, Ardabil Branch in 2009-2010 cropping year. The Experiment was conducted of randomized complete block design (RB) with three replications. Treatment used on the Single cross 704 genotype was at three Conditions (peat based humic fertilizer; leonardite based humic fertilizer; without the application of humic fertilizer). Results showed that there was significant difference between the experimental conditions (test solution) in terms of dry matter percentage of stem at 1% level and in terms of dry matter percentage of leaf at 5% level. The results of the comparison data on the experimental conditions (test solution) showed the liquid Humic fertilizer based on Leonardite, in terms of traits such as dry matter percentage of stem and dry matter percentage of leaf and respectively, with average of 48.94 and 54.58 had the greatest percentage.
