Effective use of various forms of nitrogen fertilizers in barley cultivation

Abstract The paper aims to assess the use of various forms nitrogen fertilizers (seedbed dressing and foliar dressing) in barley cultivation steppe forest-steppe zones Omsk region. research objects were barley, fertilizers, ordinary chernozem, meadow chernozem. Variety – Sasha. most agronomic efficiency zone, 5.52 kg grain derived from 1 fertilizer nitrogen, was yielded response N 30 form ammonium nitrate urea during sowing. 60 + fertilizing) resulted a reimbursement active agent maximum amount 4.44 (ammonium urea, UAN). greatest 11.11 UAN urea). richest harvest taken following seedbed supplementary fertilizing applied together growing season total dose kg/ha. In this case, yield did not reliably depend on used; greater effect zone.
