From 2016 to 2017, an experiment was conducted at Razi University Organic Farming to identify the best organic fertilizers for organic sesame production. The research was carried out in the split-plot design based on a randomized complete block design with three replications. Comparison of soil nitrate in the post-planting stage of sesame with soil before the experiment shows that organic nitrate storage with an application of treatments of 10 and 20 t ha-1 of animal manure is 36 and 63% and green manure of fenugreek, berseem clover, and hairy vetch is 63, 54, and 23%, respectively. The reason for improving grain yield is the positive role of animal manure and green manure in the fertility and balance of soil elements. The plant doesn’t face a lack of nutrients and increases the concentration of essential growth elements in the leaves, which increases grain yield. Fenugreek and berseem clover were higher than hairy vetch due to higher nitrogen yield. In the post-harvesting stage of sesame, soil experiments revealed that approximately 24% organic carbon, 58% phosphorus, 16% nitrogen, 63% nitrate, and 50% ammonium were stored in the soil. Potassium content was 13% lower than in soil before the experiment. In general, this study showed that the application of animal and green manure by providing physical and chemical properties of soil in organic field conditions leads to improved traits associated with sesame growth and, ultimately, grain yield.
