| Abstract | ||
| The experiment was carried out at private farms in Al-Hassar area /Altun Kupri district / Kirkuk governorate during the autumn growing season (2021-2022). The experiment included two factors, the first Factor is six concentrations of nano fertilizer (20:20:20 NPK) vizcontrol(without addition), 1.5,2.5,3.5,4.5,5.5 gL_1 . The second factor is two varaieties of potato namely ,Rivira and marfona. The experiment was carried out according to Randomized Complete Block Design (RCBD) with three replicates The results showed that the spraying with nano _fertilizer at a concentration of 4.5gL_1 gave significantly increment in the plant height,number of aerial stems ,chlorophyll content of leaves, marketing yield per plant and total yield 78.515 cm and 2.854 stems _1 and 16.700 and 485.900gm plant_1and 28.435 tons ha_1,respectively .whereas,the spraying with a concentration of 5.5gL_1gave significantly increment leaf area . The study also showed a Rivera variety had highest values in as all the Studied characteristics . On the other hand, the interaction treatment Rivera variety increased significantly in the plant height and leaf area , while the interaction treatment between the concentration 4.5gm L_1 and Rivera variety gave a significant improvemant in the other of the studied characteristics. | ||
