Abstract

A field study was done in two locations, Grdarasha and Qlyasan. The experiment included three factors, the first factor was Nano-NPK spraying with 4 concentrations (0, 150, 300, and 450) µg cm-3, the second factor was two periods of spraying according to Zadoks scale Z-21 and Z-43 and the third factor was two bread wheat cultivars (C1 = Adana-99 and C2= Aras). Numerous quantitative and qualitative parameters were studied. The mentioned factors showed a positive role, the fertilization treatments of 450 µg cm-3 recorded the highest values of plant height (96.17 and 73.24) cm, flag leaf area (33.19 and 33.04) cm2, number of grain spike-1 (48.76 and 41.78), weight of grain spike-1 (1.95 and 1.54) g, seed index (38.54 and 39.35) g, grain yield (4.93 and 4.84) t ha-1 and protein yield (707.28 and 609.46) kg ha-1 for both locations respectively. Spraying the Nano - fertilizer at the second stage had significant impact on some traits, the highest values in flag leaf area, no spikelet spike -1, seed index, grain yield and protein yield was (30.83 and 32.17) cm2, (17.57 and 17.60), (37.10 and 39.16) g, (4.49 and 4.34) t ha-1and (621.86 and 533.70) kg ha-1. In contrast, the second cultivar Aras surprised Adana in most of the traits. The interaction treatments (450 mg L-1x Booting stage x Ara's cultivars) recorded the highest seed and protein production (5.29 and 5.71) t ha-1 seed yield and (763.29 and 717.27) kg ha-1 protein yield for both locations respectively. It is appeared from the three studied factors and their combination significant influences on most of the studied traits.
