Abstract :

There is a need to increase wheat productivity world wide, in particular in developing countries. There are different scientific reports about application of humic substances in crops. Humic preparations are increasingly applied as stimulators in plant breeding. Humates of brown coal, peat and soils are mostly studied while sapropel humates are much less known. Because this, we conducted an experiment for evaluation effect of a humic preparation derived from sapropel on different wheat genotypes. Yield and some of yield components measured. ANOVA showed that potassium humate had significantly effect on seeds number per spike, seed weight per spike, yield and biomass at probability level of 1 %. But it had not significantly effect on 1000 seed weight and plant height. So there were not differences between interactions (application of humate x genotypes) for all of characters. Potassium humate significantly increased grain yield. Totally, yield of wheat increased from 2.5 to 3.6 ton/ha by use of applied humic fertilizer. Key words: Wheat, Potassium Humate, Sapropel, Yield, Yield Components_
