Yield and lodging response of tef [Eragrostis tef (Zucc) trotter] varieties to nitrogen and silicon application rates.

ABSTRACT: Lodging, poor crop varieties and nitrogen management are among the main tef cultivation problems in acidic soils of northwestern Ethiopia. Though Si has been shown to improve crop yield and lodging resistance, knowledge of its effect on tef, along genotypes and nitrogen, is yet to be uncovered. Therefore, a 4 × 2 × 2 factorial field experiment was conducted on fixed experimental plot at the Koga irrigation scheme to assess yield and lodging responses of tef varieties to nitrogen and silicon fertilizer rates during two consecutive years of 2021 and 2022. The experiment comprised four nitrogen levels: 0 (N1), 23 (N2), 46 (N3), and 92 kg N ha^-1(N4), two Si levels: 0 (Si1) and 485 (Si2) kg ha^-1, and two improved varieties: Hiber-1 (V1) and Quncho (V2) treatment combinatio
