تأثير التسميد العضوي و المعدني في صفات الحاصل و نوعيته لتركيبين وراثيين من الذرة الصفراء zea mays

Abstract EN

Tow field experiment was carried out at Al-Jelawya village / Babel during the spring season (2015 and 2016) in order to study effect of organic and mineral fertilization: F0 (comparison treatment), F1(Nitrogen fertilization as ureia 320 kg/ha), F2 (original fertilization excrement domestics made in Holland 6 ton/ha) , F3 (added half of tow fertilization organic and mineral) on yield , quality two genotypes of mays : Baghdad class (Iraqi) and Sultan class (Holland).

In factorial experiments,Using RCBD design.

The result showed: the varieties : Baghdad variety was exceeded at all studied traits and for two seasons : ear length (20.12 , 21.07)cm, row/ear (14.23 , 14.33) row/ear, grain yield (164.33 , 169.53)g/plant, and protein ratio (10.47 , 10.362)% .

While Holland variety was exceeded at 500 kernels/weight(145.51, 145.91), oil ratio (4.733, 4.638)% for two seasons.

In ather side fertilization was superior F1(nitrogen fertilization) at all studied traits for both seasons except the oil ratio it was superior at (F0).

It gives :ear length (21.09 , 21.99)cm, row/ear (15.50 , 16.30), kernel/ear (44.66 , 45.95), 500 kernels/weight (146.83, 147.68)gm , grain yield (188.40 , 199.70)g/plant, and protein ratio (11.489 , 11.252)%.

While the interaction between verities and fertilization: Baghdad with F1 and for both seasons was superior for studied traits: ear length (21.96 , 23.02)cm, row/ear (16.17 , 16.41), kernel/ear (46.53 , 46.12), grain yield (205.66 , 217.85)g/plant and protein ratio (11.75 , 11.447)% .

While the Holland verity with F1 for both seasons was superiors at 500 kernels/weight (151.39 , 152.23)g, but the oil ratio was superior with F0 (5.243 , 4.895).
