“…Prova64, detailed in Triberti et al (2016), started in the autumn 1966 and aimed at studying the combined effects of mineral fertilisers on maize and wheat yield, grown in various rotations. Continuous crops are as follows: Wcont, continuous winter wheat (Triticum aestivum L.); Ccont, continuous maize (Zea mays L.); 2-year rotation (Rot2): maize -wheat; 9-year rotation (Rot9):…”

Yield averages and variability from three long-term agronomic experiments (LTAEs) have been used in a preference scheme for cropping system options by means of a dominance approach. Preference maps are obtained and include both parametric and stochastic dominance based on yield level and risk for wheat and maize crops grown in the Mediterranean area. Dominance method could add to classic ANOVA the direction of the effect of a treatment and a comparative approach. It allowed comparing technical options and practices on the basis of treatments explored in 3 still running LTAEs: rotation, tillage, mineral fertilisation level and organic amendment. IntroductionIn the last decades, agricultural risks have been mainly related to environmental hazards that are linked to the use of fertilisers and pesticides. In this instance, risk has been expressed as the amount of polluted soils and ground-water concentration levels. Agricultural activity also induces risk in terms of hydrological land instability (landslides), soil conservation (erosion), and air pollution (e.g. spreading of slurries near urban areas). All of these risks deal with environmental and human health. But risk is an important issue also from an economic standpoint: farm income depends on crop yields, which can be highly variable over the years, mainly influenced by market, weather (Uzea et al., 2014), and cultural practices.A cropped land is an ecosystem that farmer maintains in a plagioclimax, controlling the effects of weather uncertainties and the other species competition. Recently climate is changing the rules of the game, adding fluctuations that farmers are not ready to cope with: longer drought spells, rainfalls of huge intensity and duration, temperature fluctuations are some relevant features of the changing climate. Mavi and Tupper (2004) identified in weed germination and survival of insect and pests the main processes that severe weather brings about on crop yields. Mugo (1999) claimed that intensification of extreme events will increase seedling sufferance to frost and water stress.Several options have been studied to reduce risk, including the choice of a proper variety and timing of cultural operations (e.g. sowing, fertilising, tillage; Sivakumar and Iotha, 2008). Farmers know that a full prevention is hardly attainable: an adverse event happening at a critical phenological stage can be sufficient to cancel out a year's yield.Net incomes from arable crop productions are decreasing and a common way to address risk is the adoption of insurance: a way to get around the problem that allows continuing following traditional cultural protocols. Nevertheless, farmers are eager to know which cropping system can better ensure the economic sustainability in a context of high weather fluctuation.To this scope, long-term data are required, and long-term agronomic experiments (LTAEs) can offer an unexploited resource of knowledge.Nowadays many LTAEs are available all over the world. The first ones were established in middle 19 th century and we...

“…Crop rotation has been recaptured the global attention to solve the increasing agroecological problems such as declining soil quality and climate change resulting from short rotation and monocropping . Crop rotation is an effective approach for carbon sequestration as compared to growing same type of crop continuously (Triberti et al 2016). It is a potential practice to reduce the emissions of CH 4 and other GHGs in irrigated-rice fields (Theisen et al 2017).…”

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.

Thus, to identify whether conservation tillage practices (MT/NT and crop rotation) can mitigate both soil GHG emissions and net GWP is still unclear, particularly in semi-arid areas where the weight of direct N 2 0 losses is expected to be lower.…”

Conservation tillage and crop rotations improve soil quality. However, the impact of these practices on greenhouse gas (GHG) emissions and crop yields is not well defined, particularly in dry climates. A rainfed 2-year field-experiment was conducted to evaluate the effect of three long-term (17-18 years) tillage systems (Conventional Tillage (CT), Minimum Tillage (MT) and No Tillage (NT)) and two cropping systems (rotational wheat (Triticum aestivum L.) preceded by fallow, and wheat in monoculture), on nitrous oxide (N2 0) and methane (CH4) emissions, during two field campaigns. Soil mineral N, water-filled pore space, dissolved organic carbon (C) and grain yield were measured and yield-scaled N 2 0 emissions, N surplus and Global Warming Potentials (GWP) were calculated. No tillage only decreased cumulative N 2 0 losses (compared to MT/CT) during campaign 1 (the driest campaign with least fertilizer N input), while tillage did not affect CH4 oxidation. The GWP demonstrated that the enhancement of C stocks under NT caused this tillage management to decrease overall CO2 equivalent emissions. Monoculture increased N2O fluxes during campaign 2 (normal year and conventional N input) and decreased CH4 uptake, as opposed to rotational wheat. Conversely, wheat in monoculture tended to increase soil organic C stocks and therefore resulted in a lower GWP, but differences were not statistically significant. Grain yields were strongly influenced by climatic variability. The NT and CT treatments yielded most during the dry and the normal campaign, and the yield-scaled N 2 0 emissions followed the same tendency. Minimum tillage was not an adequate tillage management considering the GWP and the yield-scaled N 2 0 emissions (which were 39% lower in NT with respect to MT). Regarding the crop effect, wheat in rotation resulted in a 32% increase in grain yield and 31% mitigation of yield-scaled N2O emissions. Low cumulative N2O fluxes (<250gN 2 O-Nha _1 campaign -1 ) highlighted the relevance of soil organic C and C0 2 emissions from inputs and operations in rainfed semi-arid cropping systems. This study suggests that NT and crop rotation can be recommended as good agricultural practices in order to establish an optimal balance between GHGs fluxes, GWP, yield-scaled N 2 0 emissions and N surpluses.
