Potato growth in humid climate regions is facing increasing challenges due to short period stresses in water deficit and excess. However, there is a lack of quantitative information on the effects of short period of water stress on potato plant growth and its implications on potato yield and tuber quality. In this study, we conducted a pot experiment to test the effects of short period (2 weeks) of

In the agricultural water resources system, the regional yield is hard to be simulated accurately under the impacts of spatial heterogeneities of soil, weather, and crop types. The optimal water allocation schemes may be not in accordance with actual conditions due to neglecting the actual crop growth process. Meanwhile, the uncertainties in the simulation-optimization models are not easy to be addressed

Achieving rice self-sufficiency in West Africa will require an expansion of the irrigated rice area under water-scarce conditions. However, little is known about how much area can be irrigated and where and when water-saving practices could be used. The objective of this study was to assess potentially irrigable lands for irrigated rice cultivation under water-saving technology in Burkina Faso. A two-step

The structural deficit of water resources in Mediterranean areas forces us to search for new sources of water for irrigation as a mandatory requirement for a sustainable agriculture. However, given their critical role in soil fertility, the impacts of irrigation in soil microbial communities must be carefully considered alongside the crop responses. Here, we evaluate the impacts of irrigation with

Faba bean (Vicia faba L.), a major legume crop, helps in maintaining soil health by fixing atmospheric nitrogen (N2) and thus mostly used as a rotational crop. However, faba bean is sensitive to water stress, which limits its yield potential in water-limited environments. The objectives of the present study were to (i) characterize the agro-physiological performance of 14 faba bean genotypes with different

Impacts of soil conservation measures on runoff and soil loss have not been fully considered in the regions where soil erosion control and water resource are both important.
