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

الملخص EN

A field experiment was carried out during the autumn season of 2017 in one of the farmers' fields in Qurna / Al-Ghamiej (65 km north of Basra city center) in silty clay soil at 47.27 degrees east and 30.56 degrees north latitude.

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

Main plots involved the cultivars (Kafair, Al-khair and Anqath).

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

, respectively.

thereby, the number of experimental units is 36 units and the area (3 × 4) m 2 for each the experimental unit.

The aim of study is evaluating effect of spray varieties of nano fertilizer on three varieties of Sorghum bicolor (L.

) moench The variable studied were number of grains in the head, weight of 1000 grains (g) and the grain yield ton.

ha -1 The results of the analysis showed there were significant differences among varieties in most of the studied parameters.

Variety AL-Khair showed the highest values for yield components in final yield 5.74 ton ha-1.

The results showed foliar application treatment F3 gave the highest number of grains in the head (1713 seed head-1), weight of 1000 grains (30.95 g ) and Grain Yield (5.9 ton ha-1) compared with nano fertilizer treatment by using each element alone and the non-additive treatment.

The interaction between varieties and the addition of nano fertilizer had a significant effect on yield components.

Whereas treatment of Variety AL-Khair and addition two elements together had the highest grain reached 6.77 ton.

ha-1 because of its superiority in yield component compared to other combinations.
