Abstract EN

A field experiment was carried out during the autumn season of 2016 in one of the Agricultural fields in the area of Abu- Guelana, which is 13 km from the center of Muthanna province, To find out the effect of potassium and boron spraying in the yield and quality characteristics, for sunflower crop - variety Luleo.

Used in this study completely randomized block design Arrangement factorial experiment, The study included two factors: The first factors of four concentrations of potassium spray (0, 2500, 5000, 7500) mg K L-1, and the second factor four concentrations of boron spray (0, 50, 100, 150) mg B L-1.

The mean of the treatments was compared with the least significant difference (L.

S.

D) at a probability level of 0.05% .

Results showed that the potassium spray treatment 7500 mg k L-1 was significantly higher in all studied traits, (number of seeds/head, weight of thousand seed, fertility percentage, seed yield, total seed yield and total oil yield), The results showed that the treatment of boron spray with 100 mg B L-1 concentration was significantly higher in all studied traits.

The overlap treatment showed significant superiority in all the traits.
