Yield of some wheat varieties depending on fertilization with a combination of mineral fertilizers and zeolites

Abstract

Zeolite improves the structure of the soil and reduces acidity, which is of great significance for agricultural production that happens on soils with low pH values. It has shown exceptional results in improving soil characteristics, thus increasing the yield and quality of cultivated plants. The aim of our study was to determine the yield and some qualitative properties of numerous wheat varieties, depending on the mineral fertilizers and zeolites application. The experiments were performed in 2018/19 and 2019/20, in the area of Southern Serbia (Bojnik). The research involved 4 wheat varieties and 4 variants of fertilization, including mineral fertilizers and zeolite. The combination of mineral fertilizers and zeolites did not show noteworthy differences in the mass of 1000 grains when it comes to both varieties and fertilization variants. Hectolitre weight of grain was significantly higher on the variant with a combination of mineral fertilizers and zeolites than on the control variant. All fertilization variants had a significantly higher grain yield compared to the control variant. The variant on which the combination of mineral fertilizers and a higher dose of zeolite were applied achieved a significantly higher grain yield compared to the variant with mineral fertilizers. Varieties Pobeda and Nikol, with the application of mineral fertilizers and zeolite combination, achieved the highest yields. On acid soils, it is necessary to apply fertilizers and soil improvers so that the yields of cultivated plants will be satisfactory.
