Abstract

Water availability is one of the major physiological factors influencing plant growth and development. An assessment study has been done at the Szent István University, Gödöllő to evaluate and identify the water footprint of protein yield of field crop species. Twelve field crop species (Sugar beet Beta vulgaris, spring and winter barley Hordeum vulgare, winter wheat Triticum aestivum, maize Zea mays, sunflower Helianthus annuus, peas Pisum sativum, potato Solanum tuberosum, alfalfa Medicago sativa, oilseed rape Brassica napus, rye Secale cereale and oats Avena sativa) were involved in the study. Evapotranspiration patterns of the crops studied have been identified by the regular agroclimatology methodology and physiologically reliable protein ranges within crop yields were evaluated. The results obtained suggest, that water footprint of cereals proved to be the lowest, however maize values were highly affected by the high variability of protein yield. Oilseed crops had considerably high protein yield with medium water efficiency. Alfalfa, potato and sugar beet water footprints were in accordance with their evapotranspiration patterns. Protein based water footprint assessment seems to be more applicable in crop species evaluations than that of yield based methodologies.

匈牙利农田12种作物产量蛋白质含量的水足迹
水分有效性是影响植物生长发育的主要生理因素之一。在森特István大学(Gödöllő)进行了一项评估研究,以评估和确定大田作物品种蛋白质产量的水足迹。12种大田作物(甜菜Beta vulgaris、春小麦和冬大麦Hordeum vulgare、冬小麦Triticum aestivum、玉米Zea mays、向日葵Helianthus annuus、豌豆Pisum sativum、马铃薯Solanum tuberosum、苜蓿Medicago sativa、油菜Brassica napus、黑麦Secale cereale和燕麦Avena sativa)参与了研究。通过常规农业气候学方法确定了所研究作物的蒸散模式,并评估了作物产量内生理上可靠的蛋白质范围。结果表明,谷物的水足迹是最低的,但玉米的价值受到蛋白质产量的高变异性的高度影响。油籽作物蛋白质产量较高,水分利用效率中等。苜蓿、马铃薯和甜菜的水分足迹与它们的蒸散规律一致。以蛋白质为基础的水足迹评价似乎比以产量为基础的方法更适用于作物品种评价。
