Abstract
Abstract A field experiment was carried out at Al-Hamidhiya research station of the College of Agriculture - University of Anbar, located within 43.39 longitude, 33.44 latitude and 53 m heights above sea level during Winter seasons 2018-2019 and 2019-2020, with aim of studying the effect of levels of potassium fertilizer, nano and mineral zinc on the yield of three oat cultivars. The split-split-plot arrangement was used according to a randomized complete block design (RCBD) with three replications. The main plots included potassium concentrations (0, 6000, 3000 nm, and 6000 nm) mg K l -1 , while the subplot included zinc concentrations (0, 50 and 50 nm) mg Zn l -1 , while the cultivars were in the sub-sub plots (Hamel, Carrolup and Genzania). The results of the study indicate that the varieties differed significantly in all studied traits. Genzania cultivar outperformed in terms of grain yield (6.25 and 6.19 ton ha -1 ) and biological yield (16.37 and 16.26 ton ha -1 ) the two seasons, respectively. In addition, spraying zinc on the plant had a positive role in improving the yield and its components, as the treatment 50 mg Zn L -1 gave grain yield of 6.24 and 6.06 tons’ ha -1 for both seasons respectively, adding potassium improved the components of the yield, which was reflected in the yield in which the treatment 6000 nm mg K L -1 was superior with seed yield of 7.05 and 6.84 ton ha -1 for the two seasons respectively. Also, the two-way interaction between the concentrations of potassium and zinc, potassium and cultivars, and zinc and cultivars had a significant effect on most of the studied traits. The three-way interaction between the study factors had a significant effect on the studied traits, which was evident in seed yield, as the combination (Genzania sprayed with 3000nm K + 50 mg Zn L -1 ) gave the highest grain yield of 8.30 for the first season, while the plants of the variety Hamel sprayed with 6000nm K + 50 mg Zn L -1 gave the highest grain yield of 7.440 ton ha -1 for the second season.
