| Abstract | ||
| The experiment was conducted in one of the agricultural fields in Rashidiya area in Mosul governorate in the fall season 2021-2022, and the process of planting seeds for the Arizona potato variety was conducted on 4/9/2021 in which the fertilization process with urea was used. The study included fertilizer injection systems (once and twice) and compared four injection rates Fertilizer (0, 240, 320 and 400) kg/ha, type of fertilizer (dry, liquid) and its effect on (leaf area, dry matter weight of vegetative mass, average tuber weight, net profit). ) and with three replications and the averages were compared using Duncan''s test for all limits at the 5% probability level. The results showed the highest leaf area at the injection rates of 400 kg/ha at 49.18 cm2, while it gave the lowest leaf area when the comparison treatment (Control) was 30.55 cm2, while it achieved the highest leaf area when dry manure when scattered (twice) an area of 37.59 cm2 and it gave the leaf area when scattered ( once) of 35.47 cm2. While the dry weight of the vegetative group achieved the highest weight of 58.67 g, and the control treatment gave the average injection rates 30 g. In the dry manure, the highest weight of the dry matter of the vegetative group was 51 g/plant when scattered (twice), while it gave the lowest dry weight of the vegetative group at ( once) 45.67 g/plant. The results showed that there were slight significant differences in the tuber weight rate, as the comparison treatment (Control) gave the average tuber weight injection rates of 0.14 kg / plant, while the average injection rates achieved the tuber weight rate of 0.15 kilograms / plant. As for the dry manure, there is no significant difference in The average tuber weight was 0.15 kg/plant for each sprouting (once and twice). The results achieved at average injection rates the highest net profit 28195256.67 d/ha, while the lowest net profit at the treatment (Control) gave 11330220.00 dinars/ha. As for the dry manure, there was no significant difference in the net profit characteristic, it gave the net profit 18451886.67 and 19398833.33 dinars/ ha for both scattering (once and twice) respectively | ||
