Abstract
A field Experiment was Conducted on Fenugreek Crop in University of Tikrit Agricultural Farms, in a factorial Randomized Complete Block Design with Two factors. The first was Inoculation with rhizobium bacterial [with and without inoculation ]and the second was addition of Cobalt [0,2 mg / l sprayed on the Plants 2 mgl added with irrigated water ,2+2 mixed spray and irrigate]The Important results obtained in this study were summarized below:- 1-Inoculated plants which received 2+2 mgL of mixed Cobalt consist on a highest concentration of macro and micro elements compared with lowest concentration of these elements in a control plant . 2-Inoculated plants with 2+2 mgL of mixed cobalt gave a highest significant values in all vegetative characteristics [plant high, number of leaves- number of branch- %vegetative dw, %root dw ,leaf area, number and weight of total and active nodules]Compared with a control plants which gave the lowest values in all of these characteristics . 3-Inoculated plants with 2+2 mgL of mixed cobalt gave a long pod-long number of pod plant- long number of seed pod- long 100 seed weight- long dry mater in the seeds and yield compared with lowest values in a control plants. 4-Inoculated plants with2+2 mgl of mixed cobalt gave a highest significant ant values in gelatinous substances [30.8 gm100 gm seed] a highest oils[9.3 gm seeds]- a highest VB12[in the leaves 0.285 mgkg-0.321 mgkg in the root and 0.480 mgkg in the nodules]Compared with 20.3 gm100gm seeds of gelatinous substances – 7.1gm100gm seeds of oils- o.o8 mgkg of VB12 in the leaves- 0.087 mgkg VB12in th roots- 0.165 mgkg VB12 in the nodules in the control plants.
