Abstract
A field experiment was conducted in one of the fields in Babylon province to study the effect of adding different levels of yungrin leaf fertilizer on the growth and yield of three cultivars of maize (IPA 5012, Buhooth 106 and Fajer). It was obtained from the Public Authority for Agricultural Research. Use randomized complete block design (RCBD) with a system of factorial experiments and three replicates (Al-Rawi and Khalaf Allah, 2000). The experiment included two factors, the first factor concentrations of spraying yungrin fertilizer (25,12.5,0) g per 20 Liter water and symbolized with the symbol (T1, T2, T3) As for the second factor, it includes three cultivars: (IPA 5012, Buhooth 106 and Fajer), and it has a symbol (V1, V2, V3). The results showed are Buhooth cultivars 106 V1) outperformed all studied plant height traits. Cm, leaf area. Cm2, the number leaves.Plant-1, Number of cob. Plant -1 and the length of the cob. Cm , it reached (194.42 cm, 6418.33 cm 2, 14.61 leaf.Plant-1, 1.61 cob. Plant -1 and 19.83 cm). Concentrations (T) showed the spray of yungrin leaf fertilizer significantly superior, as the concentration gave 25 (T3) g. L-1 the highest mean of all studied traits (plant height. Cm, leaf area. Cm2, number of leaves. Cm) amounted to (197.33 cm, 6000.66 cm2, 14.80 leaf. Plant -1 ,1.56 cob. Plant -1and 19.31 cm). The results of the bilateral interaction between the cultivars and the concentrations (V, T) showed a significant effect, as the combination V1 and T3 gave the highest mean in the traits: plant height. cm, leaf area. cm2 and the number of cob. Plant-1, it reached (198.93 cm, 6485.33 cm 2 and 1.90 cob. Plant -1) while the combination gave V3 with the control treatment (T1) the lowest average in all traits: plant height. cm, leaf area. cm2, the number of leaves. Plant-1, Number of cob. Plant-1 and the length of the cob. Cm as it reached (179.00 cm, 4822.00 cm2, 12.03 leaf. Plant-1, 0.77 cob. Plant -1 and 18.00 cm).
