Response of two flax cultivars to chemical and nano-fertilizers and their influence on growth and yield parameters

الملخص EN

This study was done during (11th of November to 8th of June ,2020) at two locations (Grdarasha and Grdmala) in Erbil governorate to test the influence of seven fertilizer treatments [Control, Nano-NPK, Super Nano, Triple super phosphate, Urea, KCl and agricultural sulphate], two flax cultivars (Libra and Brazowe) and their interactions on growth, yield and oil content.

The results indicated to significant effect of the studied factors and their interactions on growth, yield and oil % of the two flax seeds.

The maximum seed yield 4.65 and 6.27 g plant-1 was recorded from plots sprayed with Nano-NPK, while the lowest values 2.58 and 4.45 g plant-1 was recorded from control in both locations respectively.

While the highest seed yield value 4.42 and 5.86 g plant-1 were obtained from Brazowe cultivar.

On the other hand, the interaction treatment of (Super Nano* Brazowe cultivar) and (TSP * Brazowe) were recorded the highest seed yield per plant which were 5.97 and 6.99 g plant-1 respectively.

The highest oil values 32.96, 30.73 and 33.42% was observed from treatments Nano-NPK, Brazowe cultivar and treatment combination of (Nano-NPK* Brazowe cultivar) respectively.
