| Abstract | ||
| A field experiment was conducted during winter season of 2021-2022 in two sites, in Field Crops Department - College of Agriculture and Forestry/ University of Mosul and other in Badoush Dam site, to assess response of three varieties of rapeseed to foliar spraying of zinc and its impact on the qualities of growth and yield. The experiment was applied in a split plot design. With three replications according to Randomized complete Block Design, as the main Plot contained three verities of rapeseed (Pactol, Srew, Rendy), while the secondary Plot contained three concentrations of zinc (0, 25, 50 mg L-1). The findings showed that the Pactol variety give the tallest mean height of plant. Conversely, the Srew variety gave the most branches on for plant, siliques number for plant, a thousand seeds' weight, plant yield, oil percentage, oil yield and for both sites. Findings indicated 25 mg L-1 concentration, which yielded the tallest mean plant height, branch number for plant and oil percentage. On the contrary, zinc concentration resulted in 50 mg L-1, which amounted to the maximum overall mean dry weight of plant, siliques number for plant, seed number for silique, a thousand seeds' weight, seed yield and oil yield for both sites. The findings also established that the cultivation of the Srew variety, complemented by zinc at 50 mg L-1 concentration, yielded the highest outcomes concerning the dry weight of the plant in the dam site, siliques number for plant, seed yield and oil yield in both sites. | ||
