Abstract

The productivity food barley is constrained by the competition of weed and agronomic practices. An experiment was conducted to evaluate the effect of weeding frequency on Relative Weed Density, Weed intensity, Relative yield loss and Yield of Food barley varieties at Amuru District of Horo Guduru Wollega Zone of Oromia National Regional State in 2016 main cropping season. The experiment was laid down in a Randomized Complete Block Design (RCBD) with three replications. The treatments were factorial combination of four weeding frequencies (weedy check, one time weeding, two times weeding and three times weeding) and five food barley varieties (HB 1307, CROSS 41/98, GOBE, EH1493 and Local). The major weed species identified in the study area were Setaria pumila with relative density (31.74%), population density (84 plants m^-2) and an intensity of 2.1; Snowdenia polystachya with relative density (16.6%), population density ( 44) with an intensity of 1.1; and Polygonum spp with relative density (10.57%), population density (28) and an intensity of 0.95. While others weed species constituted about 27.17% of a total weed population with a density of 72 plants m^-2. Weeding frequency and varieties significantly affected biological and grain yields, and relative yield loss of food barley. Three times weeded treatment gave significantly higher grain (1422 kgha¹) and biological (3877.78 kgha¹) yields. Moreover, HB 1307 variety gave significantly higher grain (1292 kgha¹) and biological (3513.9 kgha¹) yields. Therefore, three times weeding with HB 1307 variety is recommended to increase the production and productivity of food barley in the study area.
