The Effect Of Microbial Fertilizers on The Mineral Content Of Some Cowpea (Vigna unguiculuta L. Walp.) Varieties

Cowpea plant and other legumes are known as important protein sources, but their effect on mineral content in human nutrition is less known. Legumes are of great importance in developing countries where access to animal protein sources is difficult. Cowpea grains and leaves are a source of carbohydrates, proteins, fats, ß-carotene and vitamins B and C necessary for a healthy diet. This study was conducted to investigate the mineral matter contents of different foliar applications of microbial fertilizer to some cowpea (Vigna unguiculata L. Walp) cultivars (Akkız 86, Karagöz 86). The research was conducted in the experimental field of Erciyes University Agricultural Research and Application Center in the 2022 growing season. Grains obtained from Akkız 86 and Karagöz 86 cowpea varieties were used as plant material. In the study, the mineral matter contents of cowpea grains were examined and the mean values obtained from the cultivar*bacteria interaction were examined: boron 17.457-14.200 ppm, calcium 1127.27-859.86 ppm, copper 13.963-10. 330 ppm, iron 42.590-25.923 ppm, potassium 8104.8-6150.9 ppm, magnesium 1811.29-1260.25 ppm, manganese 18.493-12.520 ppm, phosphorus 5258.68-3621.19 ppm, sulfur 1091.97-3621.19 ppm and zinc 56.53-36.887 ppm.
