EFFECTIVENESS OF SPRING BARLEY IN THE FOREST-STEPPE OF NOVOSIBIRSK OB

Abstract

The authors speak about the barley, which is the main forage crop therefore selection of crops which conform biologically to zone conditions is of great importance and urgency. Novosibirsk region produces great amount of grain but due to geographical position (far distance up to 5 000 km) its sales isn’t efficient. At the same time the region imports great amount of meat and spends high costs for transporting which results in less income of goods producers. The article analyzes new selection varieties and their response to different weather conditions; it demonstrates significant stock in grain production. Omskiy 95 variety mostly contributed to grain production during 3 years (5.5 dt/ha in comparison with the standard); Zolotnik variety contributed to grain production (5.0 dt/ha) and Zhan variety did (3.3 dt/ha). Two years data certify that Britney variety contributes greatly to grain production (9.4 dt/ha) and Omskiy 99 variety contributes on 4.1 dt/ha. The average profitability level for 3 years assumes 121.6 % of Zhan variety, 124.7 % of Zolotnik variety and the highest level 127.1 % of Omskiy 95 variety. On average 3 years data on crop yield represent high crop capacity of Omskiy 95 (34.6 dt/ha), Zolotnik variety (34.2 dt/ha), Vorsinskiy 2 variety (33.9 dt/ha) and Zhan (33.7 dt/ha). The other varieties didn’t contribute to the over standard rate. The article declares that applying barley of Odesskiy 95, Zolotnik, Vorsinskiy 2 responding differently to the climate conditions results in high sustainable crop yield and high economic efficiency.
