The Faculty of Agriculture discussed the master’s thesis tagged (the role of adding potassium humate and foliar spraying with marine algae on growth characteristics, forage yield and quality in Moringa) by Sarbaz Faki Jaafar Omar, and supervised by Prof. ) at five levels (0, 4, 8, 12 and 16 kg.ha at planting, before the first irrigation and after each mowing process, and spraying with seaweed extract Alga600 Trally and at three levels: 9, 1, and 2 ml per liter (2 and 4 ml per liter of total spray) and at two intervals after (20 and 30). A day of planting and after 19 and 25 days of mowing, which took place after 60 days of planting and after 45 days of each mowing, at a height of 20 cm from the surface of the ground, and the experiment was carried out by designing randomized complete sectors and with three replications.The study concluded that the ground addition of potassium humate at a rate of 16 kg. ha-1 and spraying at a concentration of 2 ml. L-1 and twice at each mowing stage, led to a significant superiority in the studied traits.
