Effect of Biogas Solid Waste on Mineral Content of Barley (Hordeum vulgare conv. distichon)

Abstract

In this study, it was aimed to determine the mineral contents and changes in barley (Hordeum vulgare conv. distichon) grain treated with different doses of biogas solid waste. The study was conducted for two years with 4 replications in a randomized complete block design. In the study, biogas solid waste was applied at doses of 0, 10, 20, 30 and 40 tons ha-1 and the macro (nitrogen, phosphorus, potassium, calcium and magnesium) and microelement (iron, manganese, zinc and copper) contents of the barley grains obtained were determined. Macro and microelement contents of barley grain increased with the increase in biogas solid waste application in both experimental years. It was determined that 40 tons ha-1 dose of biogas solid waste application was the most effective application on macro and micro nutrient contents of barley grain. Compared to the control treatment, 40 tons ha-1 biogas waste application increased the macroelement contents by 3.02% (maximum increase N, 7.87%) and microelement contents by 9.97% (maximum increase Cu, 22.84%). As a result, 40 tons ha-1 biogas waste application enriched the macro and micronutrient content of barley grain and biogas waste application can be used to increase the nutrient composition of barley grain, which has important areas of use in human and animal nutrition.
