In order to investigate the effect of liquid humic fertilizer on some micronutrients present in the stem of wheat genotypes, a study was conducted both on field and in vitro. Wheat genotypes being studied were sown as factorial split plot based on completely randomized blocks design, with three replications. Main Factor included two levels of irrigation and two levels of humate application as factorial to each other, whereas sub factor included wheat genotypes. Levels of main factor included: normal irrigation; normal irrigation + spraying by humic fertilizer; drought stress; drought stress+ humic fertilizer. Analysis was run on cations of elements such as iron, zinc and manganese present in the stems of genotypes being studied. Results showed that there was a significant difference between the genotypes in terms of all the elements other than iron. Likewise, the variation between interaction of irrigation levels and humic levels in terms of all the elements was significant. Terminal drought decreased contents of the elements, whereas application of humic fertilizer led to increased contents of mentioned elements. Interaction of “irrigation levels × humic levels” varied significantly in terms of all the elements, except for nitrogen, whereas the combination of irrigation and humic fertilizer application produced more value in terms of all the elements than other combinations. Interaction of “genotypes × humate levels” was significant only in terms of iron. Average water levels and average levels of Potassium humate showed that the amount of zinc, iron, manganese in drought conditions decreased than irrigation condition to the 37.95%, 27.69%, 25.75% respectively, the amount of zinc, iron, manganese on in terms of increased Potassium humate the situation without the use of Potassium humate to the 20.44%, 16.38%, 12.84%. Therefore, in order to produce high and qualitatively desirable yields on the wheat fields that are inherently deficient in any of these elements, application of the fertilizers containing these elements is inevitable.
