| Abstract | ||
| In the fall of 2022, a factorial experiment was carried out in the Bani Magan area, which is connected to the General Directorate of Agriculture of Sulaymaniyah and part of the Directorate of Agriculture of Chamchamal. The purpose of the experiment was to determine how different concentrations of nano-NPK (0, 2, and 4) g.L-1 affected the responses of seven genotypes of maize crop to different growth traits and overall yield. The experiment's results were as follows: Plant height, total grain yield, and the amount of time between seeding and 50% of male flowering were all considerably greater at 4g L-1 NPK nano-compound fertilizer concentration. The two genotypes (DKC6664 and Yugoslavian) were greatly outperformed for the 42.52-day period from sowing to 50% male flowering, and the 46.52-day period from sowing to 50% female flowering for the genotype (DKC6664). The plant height of 204.66 and 202.77 cm was significantly exceeded by two genotypes (Babylon and Bahia). Additionally, the number of grains per ear (518.06 and 513.89) was significantly exceeded by both genotypes (Erbil 215481 and DKC6664). The genotype (Yugoslavian) was significantly exceeded for the weight of 100 grains, 34.55 (g), and the total grain yield was superior for both genotypes (DKC6664 and Erbil 215481) at 9.47 and 9.37 (ton ha-1). | ||
