Response of two bread wheat (Triticum aestivum L.) varieties to foliar application of Nano fertilizers at two growing stages and its effect on their qualitative characteristics

Abstract

      This study was conducted at Sulaimani Quality Control Laboratory, Bakrajo Agricultural Research during 2022 to determine the influence of interaction treatments between four levels of Nano NPK (20:20:20) using foliar application at rates of (0, 150, 300 and 450) mg L-1 , two growth stages tillering and booting at two locations Sulaimani  with at Qilyasan Agricultural Research Station, University of Sulaimani, located at (35° 34′ 307″ N, 45° 21′ 992″ E and elevation 765 m above sea level) and Grda-rasha, the College of Agricultural Engineering Sciences research farm, Salahaddin University of Erbil, located at (Latitude 36. 10116 N and Longitude 44.00925 E and elevation of 415 meters above sea level), during winter season of 2019-2020, on quality variation of two bread wheat varieties (Adana-99 and Aras) in terms of length (mm), width (mm), thickness (mm), protein% and hectoliter kg hl-1. The highest values of bread wheat quality according to the studied characteristics of hectoliter, thickness, width and length were (78.633 kg hl-1, 3.240 mm, 3.380 mm and 6.500 mm) were recorded from interaction treatments of (Aras x booting x300 mgl-1), (Aras x booting x300 mgl-1), (Aras x booting x150 mgl-1)    and (Aras x booting x control)   respectively from wheat samples that taken from Sulaimani location. On the other hand, the highest grain protein of 14.633 % was obtained from interaction treatment of (Aras x tillering x300 mgl-1) at Erbil location. The results indicated that the spraying x300 mgl-1 regarded as a best level of Nano-NPK fertilizer.
