MACRO AND MICRO ELEMENT CONTENTS OF THE HERBAGE OF SIX DIFFERENT FENNEL (Foeniculum vulgare Mill. var. dulce) POPULATIONS USED AS FEED ADDITIVE SUBSTANCES
This study was carried out to determine the mineral element contents of the fennel herbage which can be used as an additive in animal feeds. The research was investigated in the experimental area of Kahramanmaraş Sütçü İmam University, Faculty of Agriculture and Department of Field Crops in 2017-2018 winter season and established according to the completely randomized block design (CRD) as three replications. Six fennel populations collected from different regions in Turkey Tokat1, Tokat2, Tokat3, Urfa, Burdur and Konya were used in the study. According to the research results; It was determined the mean nitrogen (2.11-2.78%), phosphorus (0.31-0.39%), calcium (1.39-1.68%), potassium (2.30-2.92%), sodium (1392-8328 mg kg-1), magnesium (0.54-0.61%), iron (215–623 mg kg-1), copper (16.83-19.87 mg kg-1). zinc (44.22- 53.68 mg kg-1), manganese (35.77-58.53 mg kg-1) content of fennel plant. Ca/P, K/Ca+Mg, Ca/Na, and K/Na ranged from 3.99-4.59, 1.20-1.38, 1.83-2.38, and 3.44-3.86, respectively. The macro elements for growth in the fennel plants as N, K, and P content had founded positively significant with all elements except Ca and Na content. The micro elements which are Fe, Cu, Zn, and Cu contents were also positively correlated with each other.
