The experiment was carried out on a farmer's field in the province of Babylon during the 2020–2021 growing season. to investigate how three different genotypes of corn (Zea mays L.) react when sprayed with varying Nahrain liquid fertilizer quantities. the General Authority for Agricultural Research, obtained. Three replicates of a system of two-factor trials was used, and the randomized complete block design (R.C.B.D.) was employed (Al-Rawi and Khalafallah, 2000). There were two variables in the experiment. The first factor was the Al-Nahrain liquid (0,2,4) ml foliar fertilizer concentrations. L-1, represented by the sign (K0, K1, K2). For the second element, it was represented by the symbol and comprised three corn varieties (Rabea, Bohuth 106, and Sarah) (S1, S2, S3). Results were evident. The cultivar Bohuth 106 (S1) performed exceptionally well in the majority of the attributes examined, including cob length (cm), number of rows (cob-1), number of grains per row, and number of grains per cob, and it produced an average of (20.3 cm, 14.50 row.cob-1, 37.76 grains.row-1 and 465.77 grain.cob-1).The analysis's findings revealed that the concentration was more than 4 ml. Cob length, cm, number of rows, cob-1, number of grains per row, number of grains per cob, and weight of 500 grains are all considered to be L-1 (K2) features in all traits that have been researched. (20.37 cm, 14.67 rows, 34.76 pieces, 424.77 grains, and 95.77 g in a cob-1 matrix). Despite the binary interaction findings showing a significant effect on majority of the features, the combination S3, K2 excelled in the attributes of cob length (cm) and weight (g-1), giving it the highest mean (20.67 cm and 110.00 g) Although the highest average in terms of grains was produced by the interaction between S1 and K2in terms of the quantity of grains per row and the number of grains per cob, offered the highest average (39.03 grains in row and 468.00 grains .cob).
