Abstract
A field study was conducted in Ramadi (about 110 kilometers west of Baghdad), Iraq (33° 25’ 15” N, 043° 18’ 26” E, with the aim of finding local alternatives to commercial organic fertilizers by recycling household and city waste at the lowest cost and applying them to fenugreek plants with the aim of increasing their nutrient content. The experiment consisted of two factors. The first factor involved applying sheep manure at three levels: 0, 6, or 8 Mg ha-1. The second factor involved spraying commercial or manufactured organic acids at three concentrations: 0.5, 1, or 1.5 ml L-1. The control treatment has been only sprayed with distilled water. The results showed that the second level of sheep manure (6 Mg ha-1) gave the highest rate of micro and macro nutrient content in fenugreek seeds. The third level of commercial organic acid (1.5 ml L-1) gave the highest content of nitrogen, phosphorus and zinc in the seeds, reaching 41.74 (gN kg-1), (5.14gP kg-1) and 32.3 (mgZn kg-1), respectively. The commercial treatment of organic acids gave a value similar to the treatments of manufactured organic acids for potassium contents in seeds, which amounted to 10.42 (gK kg-1) at the spray level (1.5 ml L-1). The second level of commercial organic acid (1 ml/l) gave the highest magnesium content in seeds, reaching 2.41(gMg kg-1). The third level of manufactured organic acid (1.5 ml/l) gave the highest percentage of iron in fenugreek seeds, which amounted to 578.7 (mgFe kg-1). The highest manganese content was found in fenugreek seeds, which reached 33.0 (mg Mn kg-1) when sprayed with the second level of manufactured acid (1 ml/l). The interaction between the second level of sheep manure and the third level (1.5 ml/l) of spraying with commercial organic acids gave the highest content of micro- and macronutrients in fenugreek seeds. The results of this study indicated that using organic acids and sheep manure could be a good way to improve the nutritional content of fenugreek seeds.
