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