| Abstract | ||
| This study was conducted in the fields of Nineveh Research Department (animal wealth) in the fall season to study the effect of different levels of potassium fertilization on the growth of maize plant Zea myas class 106, a completely randomized design was used with three replications. Each of the treatments included three levels of potassium sulfate fertilizer (K0, 0, K1, 20, K2, 30, K3 50) kg/D. The results of adding potassium fertilizer at its levels showed a significant effect on the studied traits (potassium K3 concentration showed a significant effect on the length of (the plant, leaf, ear, number of ears, the weight of ear leaves, number of ear rows, weight of (calcareous, and whole plant), which amounted to 195.5, 78.3, 10.5, 32.7, 2.50, 0.030, 16.8, 0.177, 0.30, compared with other concentrations of fertilizer and comparison treatment, which amounted to 176.6, 70.9, 9.5, 30.0, 1.75, 0.02, 14.7, 0.08, 0.29, gm/kg soil on The addition of potassium K3 level gave the highest value in terms of ash and water absorption of maize grains, which amounted to 0.420 and 61.23, respectively, compared with other concentrations and treatment, which amounted to 0.416 and 60.23 gm/kg soil, as well as an increase in the value of both dissolved and available potassium and phosphorous percentage. Which amounted to 22.0, 422.7, 26.67, gm/kg soil compared with other concentrations of fertilizer and control treatment, which amounted to 332.3, 14.07, and 23.91 gm/kg soil respectively compared to other concentrations of potassium fertilizer, and give significant effect to Both available-made ammonium, Ph. , electric conductivity but no significant nitrate content in the soil. | ||
