Allelopathic Effect of Residues Medicago sativa L. in Mineral Content and Antioxidant Enzymes of Trigonella foenum-graecum L. on Growing under Different Levels of Field Capacity

This study was conducted inside the wire house of Department Biology/ College Education for Pure Science/ Mosul University agricultural season 2018- 2019 to test effect vegetative and root residues Medicago satival on chemical content antioxidant enzyme fenugreek plant Trigonella foenum- graecum L. (Iraq Indian) growth under three different levels field capacity (25, 50 75%). The experiment designed as a factorial randomized complete block design (RCBD). result showed that addition caused an increase concentration enzymes peroxidase, catalase, nitrogen, phosphorus, potassium, calcium magnesium compared control treatment (without residues) while filed 75%, exceeded 25 50% in with exception nitrogen concentration, peroxidase catalase. On other hand, Indian cultivar superior most studied traits. Antioxidant enzyme.
