The Behavior of Some Spring Barley Varieties in the Climatic Conditions of North East Baragan Plain

In this paper we analyzed the behavior of four varieties of spring barley, i n terms of productivity, based on multi-annual testing, in order to identify and recommend the most well adapted of them to be grown in the area. The research was conducted during 2008-2010 in the Vădeni area, Braila County, on four varieties of spring barley  ( Thuringia, Anabell, Cristalia and Tunika ) . The average production of the three crop years was 2362 kg/ha. In 2008, year considered normal in terms of climate, we obtained the highest yields in all four species studied, its value falling between 2350 kg/ha for Cristalia and 3025 kg/ha for Annabell. In terms of year 2009, the production of the studied varieties ranged from 1962 kg/ha for Tunika up to 2250 kg/ha for Annabell, this year being characterized as a dry year. In the third experimental year, 2010, yields ranged from 1937 kg/ha for Cristalia and 2462 kg/ha for Annabell, this year being characterized, in terms of rainfall, as a rainy year, but rainfall was not uniformly distributed. Following the evaluation of the stability of varieties’ performance using the superiority index  (Pi) , the Annabell variety proved best  ( 28% ) . Research has shown that genetic and climatic factors have influenced the yields obtained from the four varieties studied during three experimental years. In all three experimental years, Annabell variety was superior to all other studied varieties, obtaining productions between 2337 kg/ha and 3025 kg/ha. The production of spring barley in 2008 was significantly superior to other experimental years.
