Grain yield and micronutrient concentrations of maize parental lines of new hybrid genotypes affected by the foliar application of micronutrients.

Unlabelled: It is important for the breeders to find how genetic differences may affect crop grain yield and nutrient uptake affected by micronutrient fertilization. Accordingly, with respect to our published research, the foliar application of the most deficient micronutrients (Fe, Zn and Mn) in the arid and semi-arid areas of the world affecting grain yield and nutrient concentration of maize parental lines of new hybrid genotypes was tested in a two-year experiment (2016-2017). A split plot experiment (randomized complete block design) with seven maize parental lines (G1-G7, sub-plots), and eight micronutrients treatments (main plots) including control (without spraying, M1), Zn (M2), Mn (M3), and Fe (M4) at 3 g L, Mn + Zn (M5), Fe + Zn (M6), Fe + Mn (M7), and Fe + Mn + Zn (M8) at 1.
