AbstractA field experiment was carried out at the Research Station of the College of Agriculture-University of Anbar in Hamidiyah area of Ramadi District-Anbar Governorate and located at 33º north latitude and 43º east longitude, during the winter season of 2020-2021, to study the effect of four levels of potassium fertilizer (0, 80, 160 and 240 kg K ha-1) In the form of potassium sulfateK2SO4(41.5% K)and four seeding rates(80, 100, 120 and 140 kg ha-1)on growth, yield and components of oats. The randomised complete block design (RCBD) was used according to the split-plot arrangement, with three replicates. The main plot was the seeding rates, and the subplots were potassium fertilizer levels. The results of the statistical analysis showed that the seeding rate exceeded 140kg ha-1 significantly in some studied traits: height of the plant, number of tiller m-2, number of panicles (297.4 paniclem-2), weight of 1000 grains (48.49 g) and grain yield (1,662 tons ha-1), while the seeding rate120 kg ha-1 was significantly superior to the number of grains of panicle (14.20 grains panicle-1). The results showed that fertilizer level of 160 kg K ha-1was significantly superior in most of the studied traits, such as area of flag leaf, number of panicles (310.2 paniclem-2), number of grains (14.72 grain panicle-1), the weight of 1000 grains (52.62 g) and grain yield(1.831 ton ha-1.The interaction between seeding rate and potassium fertilization significantly affected most of the studied traits. The seeding rate achieved 140 kg ha-1 with a potassium fertilizer level of 160 completed the highest values: number of tillers (398 tillers m-2) and weight of 1000 grains (55.00 g). The interaction between the seeding rate of 120 kg ha-1with level of fertilizer 160 kg K ha-1 had the highest significant overlap of the number of grains (17.07 grainspanicle-1).
