Abstract :Alternative crops like chickpea could become of interest under Pannonian climate conditions in Central Europe due to forecasted changes in climate. Therefore a two-year trial was conducted to evaluate concentrations, uptake and yields of nitrogen insert ignore into journalissuearticles values(N); during crop growth of chickpea insert ignore into journalissuearticles values(Cicer arietinum L.); compared to pea insert ignore into journalissuearticles values(Pisum sativum L.);, barley insert ignore into journalissuearticles values(Hordeum vulgare L.); and oat insert ignore into journalissuearticles values(Avena sativa L.); as affected by N fertilization with either calcium ammonium nitrate insert ignore into journalissuearticles values(CAN); or the depot fertilizer Basacote® Plus 6M insert ignore into journalissuearticles values(DF); in eastern Austria. Chickpea had the lowest above-ground dry matter insert ignore into journalissuearticles values(AGDM); and N yields among the four crops in 2006; however, it could gain higher AGDM and N yields than those of barley and oat under drought conditions in 2007. N concentrations and N yields throughout crop growth were increased by increasing rates of N fertilization insert ignore into journalissuearticles values(with CAN showing generally higher values than DF);. Chickpea had a high crop N uptake rate and a high relative N uptake rate even under drought conditions. Thus, results indicated that chickpea could be an alternative crop in dry environments for achieving reasonably N yields in Central European growing conditions
