تأثير الرش ببعض الأسمدة النانوية في حاصل ثلاثة تراكيب وراثية من الذرة البيضاء (Moench)‎ Sorghum Bicolor L

الملخص EN

Field experiment was conducted at Alqurna district province of Basrah South of Iraq to study the effect of foliar application of nano- fertilizer of zn, cu and their combination on growth parameters and yield of three varieties of sorghum plant (Kafair, Al-khair and Anqath) during autumn season of 2017.

Soil of the field was silty clay.

Experiment was conducted on split-plot factorial experiment with three replicate.

Main plots involved cultivars while sub-plots where nano - fertilizer (control (F0), 2 Kg ha-1 (F1), 1 Kg Cu ha-1 (F2) and 2 Zn ha-1 + 1 Kg Cu ha-1 (F3) ).

growth parameters no.

of day from planting to 50% flowering, no.

of day from planting to 50% flowering, plant hight (cm) leaf aea index, no.

of seed head, weight of 1000 seeds (g), grain yield (ton ha-1), biological yield (ton ha-1) harvest index (HI), % of protein in grain and protein yield (ton ha-1) wear measured.

Results of the study showed 1.

Significant differences a mong varieties in most of studded parameters.

Variety AL-khair showed highest values for growth parameters and yield components with final yield 5.74 ton ha-1 and protein yield 0.608 ton ha-1.

2.

Foliar application treatment f3 resulted in highest growth parameters (plant height, no.

of seeds head, LAI and 1000 seeds) Grain yield (5.9 ton ha-1), and protein yeild (0.680 ton ha-1).

Significant interaction between nano fertilizer And varieties was recorded for grain yield (6.77 ton ha-1) protein yield (0.753 ton ha-1).

Highest values were obtained At interaction between Al-khair and treatment f3.

superior in plant height (195.61cm), stem diameter (2.79cm), number of seeds per head (1856.46 seed head-1), while genotype Tarsan 1018 was superior in 1000 seed weight (39.27gm), seeds yield (3.219 ton ha-1).

As for Interaction the Combination of (2000 gauss× Tarsan 1018) gave the highest seeds yield (3.589 ton ha-1)
