RESPONSE OF TWO FLAX CULTIVARS TO CHEMICAL AND NANO-FERTILIZERS AND THEIR INFLUENCE ON GROWTH AND YIELD PARAMETERS

Abstract

This study was done from (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 superphosphate, Urea, KCl, and agricultural sulfate], two flax cultivars (Libra and Brazowe) and their interactions on growth, yield and oil content. The results indicated the significant effect of the studied factors and their interactions on the 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 the Brazowe cultivar. On the other hand, the interaction treatment of Super Nano*Brazowe cultivar and TSP*Brazowe have 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%) were observed from treatments Nano-NPK, Brazowe cultivar, and treatment combination of (Nano-NPK* Brazowe cultivar,) respectively.
