Impact of atmospheric precipitation on forage yield of alfalfa in droughty conditions of the Volga region

For 22 years (1989–2010), the productivity of alfalfa cultivars Eruslanka and Artemida were studied in terms of irrigation on chestnut soil. During fluctuation of the green mass yield of three cuttings of second year alfalfa from 16.5 and 18.4 to 74.0 and 74.8 t/ha, its nonlinear dependence on preci...

Description
Summary:For 22 years (1989–2010), the productivity of alfalfa cultivars Eruslanka and Artemida were studied in terms of irrigation on chestnut soil. During fluctuation of the green mass yield of three cuttings of second year alfalfa from 16.5 and 18.4 to 74.0 and 74.8 t/ha, its nonlinear dependence on precipitation was established. The relation between winter precipitation (November-March) and the yield was not revealed.
