Abstract
The experiment was conducted to assess the effect of different type of fertilizers on growth, yield and yield components of maize plant, conducted at Qlyasan Agricultural Research Farm in Sulaimani governorate, Iraq. The study was conducted during the summer growing season in (2024). Experimental treatments have been organized and experiment was laid out in a randomized completely block design with three replicates. The treatments included seven levels of different fertilizers. 150 kg N ha-1, 150 kg P2O5 ha-1, 100 kg K ha-1, Organic fertilizer of cattle manure (10 Mg ha-1), Nano NPK (20:20:20) (0.4 g L-1) and NPK (20:20:20) chemical fertilizer (150 kg ha-1), and two genotypes of maize (Fajer and Medium). The results showed that the effect was significant at (P≤0.05) on the growth criteria of a maize plant. The experiment shows the effect of fertilizers in parameters, such as: Vegetative growth, Reproductive growth, Grain, and Yield parameters. Compared to Control, Urea is a very effective fertilizer for Vegetative and Reproductive growth, in plant height (183.01, leaf number (17.91), leaf area (446.32), spike length (22.37), row spike-1 (19.00), and spike diameter (5.02), compared to Control’s (159.98), (12.87), (356.00), (18.13), (13.67), and (4.22) respectively. Finally, in Grain and Yield parameters, Urea has a greater effect compared to control in Number of grain rows-1 (48.17), Number of grain spikes-1 (915.67), 100 grain weight g (29.43), Biological yield (Mg ha-1) (30.65), Grain yield (Mg ha-1) (14.20), and Harvest index % (46.74), compared to Control’s (32.67), (446.0), (22.98), (21.87), (5.38), and (24.94) respectively.
