Determination of the nutritional status of wheat (Tri̇ti̇cum aesti̇vum l.) grown in the Erci̇ş district of Van province

The aim of this study is to evaluate the nutritional status of Karasunai Odeska and Syrena Odeska varieties wheat (Triticum aestivum L.) grown in the Erciş district of Van province, based on plant and soil analyses. This survey was conducted using a Randomized Complete Block design. For this purpose, the locations of wheat fields were marked on a map using GPS. Analyses of macro- and micro-nutrients were performed on plant and soil samples collected from 15 wheat (Triticum aestivum L.) fields in the Erciş district of Van province. The macro and micronutrient contents of wheat plant and soil samples were compared with limit values. Additionally, the physicochemical properties of the soil were examined to reveal their effects on nutrient elements. According to the findings, when considering all analysis results from plant and soil samples taken from wheat-growing areas in the Erciş district of Van province, potassium deficiency was found in the wheat plant samples. A significant portion of the soil samples showed deficiencies in N, Zn, and Mn. The lack of organic matter content in the soil samples is noteworthy. Organic matter deficiency in these soils can be addressed using sources such as burnt barnyard manure, small ruminant manure, chicken manure, compost, or leonardite. Additionally, the application of organic fertiliser can lead to changes in the soil's physicochemical properties, particularly in texture, and an increase in organic matter content, which can alleviate nitrogen deficiency and potassium deficiency caused by potassium leaching in sandy textures. However, the decrease in soil reaction (pH) for micronutrients can also alleviate zinc and manganese deficiencies.
