Effect of Organic and Inorganic Fertilizer Applications on Buckwheat Yield and Micro Element Nutrition

Abstract

The aim of this study is to investigate; the effects of organic and inorganic fertilizer applications on dry matter yield of different plant parts and microelement content of grain in two different buckwheat varieties. While main plots were formed by Aktaş and Güneş buckwheat varieties, sub plots were formed by 5 different fertilizer types (Control, Urea and Worm, Chicken, Cattle manure used as an organic fertilizers) in the experiment. Buckwheat cultivar were cultivated in April 2019 and harvested in July 2019. After harvesting, different buckwheat parts (root, shoot and grain) were determined for micro element content (Cu, Mn, Fe and Zn) with the Atomic Absorption Spectroscopy. Findings results shown that there are statistically significant differences in terms of grain yield as fertilizer applications, cultivars and cultivar fertilizer interactions. While the best results for the Cukurova region were obtained from Güneş cultivar (102.20 kg da-1) as a cultivar, the best results were obtained from the application of Urea (138.1 kg da-1) as a fertilizer application. Although there is no statistically significant difference between the cultivars in terms of grain microelement content, it was determined that there is a statistical difference between the average values of fertilizer applications as Cu, Fe and Mn content. The best results were obtained from urea application on micronutrients in Cu (35.38 mg kg-1), Fe (207.30 mg kg-1) and Mn (37.22 mg kg-1). As a result, the best type of fertilizer in the Cukurova Region is the Güneş cultivar, while the best fertilizer application is urea, which is an inorganic fertilizer. Organic fertilizer applications are not important, but the best results were obtained from cattle manure as organic fertilizer.
