Abstract

ABSTRACT Marginal land exploitation devoted to versatile crops, such as giant reed, is related to the degree of land marginality. Two experiments were conducted in two sites of Sardinia (Italy) to investigate the effects of management on dry matter yield and water productivity (WP). Experiment 1 compared four crop evapotranspiration restoring treatments (100%, 75%, 50%, 25%, and a rainfed control) over 5 years. Experiment 2 lasted 7 years and investigated zero-input supply on crop response. Experiment 1, notwithstanding well-watered conditions (Irr100), showed a higher value of biomass production during the last year monitored, but yielding only 13.5 Mg DM ha−1 and with no significant difference from Irr75. Moreover, being equal the average dry matter yield, in the Irr100, we would save 3630 m3 of irrigation water by achieving the same WP recorded in the Irr25 (25% ETc restoring). Experiment 2, being equal rainfall amount, raised WP values that picked 8.2 kg m−3 during 2018. Results indicate that in less favourable soils as the Experiment 1, well-watered conditions do not ensure better crop growth and productivity, whereas in deep soils (Experiment 2) promising productive results, as well as ecosystem services, could be obtained without any input supply.

中期试验结果表明，两种不同环境下黄竹的潜在生产力

用于种植多功能作物(如巨芦苇)的边际土地开发与土地边际程度有关。在意大利撒丁岛的两个地点进行了两个试验，研究了管理对干物质产量和水分生产力(WP)的影响。试验1比较了4种作物蒸散恢复处理(100%、75%、50%、25%和雨养对照)5年的差异。试验2为期7年，研究零投入供给对作物响应的影响。试验1在水分充足的条件下(Irr100)在监测的最后一年显示出较高的生物质产量，但产量仅为13.5 Mg DM ha - 1，与Irr75没有显著差异。此外，在平均干物质产量相等的情况下，在Irr100中，通过实现Irr25中记录的相同WP (25% ETc恢复)，我们将节省3630 m3灌溉水。试验2在降雨量相同的情况下，提高了2018年的WP值，收获了8.2 kg m−3。结果表明，在条件较差的土壤(如试验1)中，水分充足的条件并不能确保更好的作物生长和生产力，而在深层土壤(试验2)中，没有任何投入供应就可以获得有希望的生产结果和生态系统服务。

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
