تأثير نوع الوسط والرش الورقي بتراكيز من نانو الزنك والحديد المخلبي والعادي في المحتوى المعدني

Abstract EN

The study was conducted in a greenhouse at the department of Horticulture and Landscape Gardening, College of Agriculture, University of Anbar for the growing season 2019-2020 and 2020-2021 to study the effect type of the growth media and spraying with nano and normal zinc and iron on mineral content of Strawberry leaves.

First factor (M) included three of agricultural media : (River soil and Peat moss 3 : 1), (River soil and *50% Coantail +50% Alfalfa 3 : 1) and (River soil and poultry waste 3 : 1).

The second factor (S) consisted of spraying with zinc and iron nano and normal with the following concentrations (0 mg L" spraying with distilled water, normal-Zn 50 mg L', nano-Zn 10 and 20 mg L', normal-Iron 150 mg L', and nano-iron 20 and 40 mg L') in addition to the control treatment (distilled water) at dates (1/12, 20/12, 10/1 and 1/2).The test media culture showed a significant influence of mineral content of Strawberry leaves for both seasons except for the content of the leaves of zinc for first season.

The medium (M3) has contributed to achieving the best results for leaves content of N, P, K and Fe) for the two seasons and zinc for the second season.

On the other hand, the treatments of spraying with Nano and ordinary zinc and iron showed a significant effects, while the treatments (S6 and S4) for two seasons achieved the highest values of Nitrogen, the treatments (S6 and S4) for first season and the treatment (55) for second season achieved the highest values of Phosphor, the treatments (S2, S6, S1, S3 and S5) for first season and the treatments (S6 and S3) for second season achieved the highest values of potassium, the treatment (S3) for first season and the treatments (S3, S1 and $2) for second season achieved the highest values of Zink, while the treatments (S6 and S4) for two seasons achieved the highest values of Iron.
