Management of the waste produced in the fisheries and dairy industries is important for the production of organic fertilizers. Because, excessive use of chemical fertilizers can have destructive effects on the environment . Accordingly, the effect of fish waste extract and yogurt water obtained from the dairy industry were investigated on the growth of Baran wheat cultivar. The experiment was conducted in the form of a randomized complete block design with three replications under field conditions. Fish waste extract (extracted by three methods including method 1: potassium hydroxide, method 2: nitric acid + sulfuric acid, method 3: potassium sulfate + sodium bicarbonate) and also 3 types of zinc, manganese, and iron lactate were used in the form of foliar application. The results showed that grain yield and dry weight of wheat straw increased by foliar application of fish extracts and lactates. The grain yield of extraction method 1, method 2 and method 3 was 1.3, 7.2 and 13.9%, respectively. Briefly, it was for method 1 > 3 > 2. Also, the results demonstrated that grain yield and dry weight of straw were in the order of manganese lactate > iron lactate > zinc lactate. The experimental treatments also increased the 1000 seed weight, but this difference was not statistically significant. Foliar spray of lactates and fish extract increased N and K concentration of wheat , but had no effect on P concentration. In general, spraying of extracts has a positive effect on the growth and yield of wheat .
