The Response of Spring Barley (Hordeum vulgare L.) to Climate Change in Northern Serbia

Abstract

The present study assessed the effect of projected climate change on the sowing time, onset, and duration of flowering, the duration of the growing season, and the grain yield of spring barley in Northern Serbia. An AquaCrop simulation covered two climate model integration periods (2001–2030 and 2071–2100) using a dual-step approach (with and without irrigation). After considering the effect of climate change on barley production, the economic benefit of future supplemental irrigation was assessed. The model was calibrated and validated using observed field data (2006–2014), and the simulation’s outcomes for future scenarios were compared to those of the baseline period (1971–2000) that was used for the expected climate analysis. The results showed that the projected features of barley production for the 2001–2030 period did not differ much from current practice in this region. On the contrary, for the 2071–2100 period, barley was expected to be sown earlier, to prolong its vegetation, and to shorten flowering’s duration. Nevertheless, its yield was expected to remain stable. An economic feasibility assessment of irrigation in the future indicated a negative income, which is why spring barley will most likely remain rain-fed under future conditions.

Genetic Diversity and Population Structure of Serbian Barley (Hordeum vulgare L.) Collection during a 40-Year Long Breeding Period

“…The observed effect of the season on plant height is in accordance with [3,62] who demonstrated a large influence of environmental factors on the expression of stem height. The shift from later heading and flowering varieties from the first and the second breeding periods towards earlier heading and flowering genotypes from the third period could be interpreted as a strategy to avoid drought [63], which is in the Pannonian Basin and other European countries one of the main limiting factors for agriculture production [64]. The increase in thousand grain weight of both two-and six-rowed types during the breeding periods was in accordance with the findings of Schwarz et al [65] who detected consistent, although not significant, improvement of thousand grain weight from 1910 to 1990.…”

Impacts of Climate Change and Adaptation Strategies for Rainfed Barley Production in the Almería Province, Spain

“…When interested in the applications of AquaCrop for climate change impact assessment on barley, we have to move outside the Mediterranean. In a study on Northern Serbia, Daničić et al [20] found that while the flowering time and the overall phenology of the crop changed, yields were largely unimpacted in the mid-and end-century time periods. Dubey and Sharma [21] focused on the basin of the Banas River in India and showed how in the mid-century (2021-2050) time period and under RCP4.5 yields were projected to increase.…”

Influence of Variety and Nitrogen Fertilization on the Technological Parameters of Special Malts Prepared from Naked and Hulled Oat Varieties

“…Current changes in the climate show that barley, with proper malting properties, might be far harder to cultivate in the future, which is why it is important to find various cereal alternatives [16][17][18]. Furthermore, currently, in Poland and the world, there are tremendous amounts of cereal monocultures being grown, which have an impact on the depletion of soil [19,20].…”
