Summary: Water-saving through deficit irrigation management is an effective approach to improve water productivity in sustainable agriculture. Crop modeling can be used to evaluate the impact of different irrigation scenarios on yield and water productivity. This study assessed the effects of surface and sprinkler irrigation under different climatic scenarios and irrigation strategies. The results showed that reducing irrigation water by 30% improved water productivity in different growing seasons. Additionally, sprinkler irrigation can increase water productivity and sustain crop production in normal and wet years, but may have negative effects in other conditions. It is important to synchronize irrigation strategies with rainfall characteristics in areas with erratic rainfalls to enhance water productivity and maintain crop production.

Summary: A two-year field experiment in Iran explored the use of wheat cultivar mixtures with different ripening patterns to mitigate post-anthesis water stress. Results showed that under stressful conditions, heterogeneity in ripening pattern of mixtures diminished, leading to reduced differences in grain yields and agronomic characteristics. While some casual beneficial effects were observed, they were not consistent across all conditions.

Summary: Irrigation water scarcity is a main constraint affecting global crop production. The study showed that raised bed planting under deficit irrigation can compensate for the negative effects of water stress on wheat plants. Combining raised beds with 80% crop evapotranspiration significantly increased growth characteristics, photosynthetic efficiency, yield, and irrigation crop water productivity of wheat plants.

Summary: Plant water deficit index (PWDI) is a critical index for irrigation scheduling that reflects the extent of abiotic stresses. Smart irrigation scheduling based on PWDI thresholds has been suggested to maximize yields and minimize negative environmental effects. A two-year experiment on drip-irrigated cotton under film mulch was conducted to investigate the effects of PWDI-driven irrigation under saline conditions. Results showed that higher PWDI thresholds led to increased irrigation depth but decreased irrigation frequency and total volume, resulting in a deteriorated soil water and salt environment, slower growth, and lower yield and net profit. Guidelines for smart irrigation scheduling were provided based on quantitative results, taking into account water management measures and cotton market prices. An optimal PWDI threshold of 0.49 was found to maximize economic benefits and water productivity. Lower thresholds should be considered when cotton prices are low, while higher thresholds can be used to improve water efficiency. Further research is needed to consider crop sensitivity to water and salinity stresses at different growth stages and optimize irrigation depth per event.

Summary: Recycling phosphorus from wastewater to crop-soil systems using microalgae and HTC technology is a sustainable strategy to improve plant PUE. Charring microalgae biomass into hydrochars promotes the transformation of soluble and exchangeable P into Fe/Al-bound P, enhancing soil P availability and improving PUE. Application of hydrochars from microalgae-derived biomass resulted in slow and persistent release of P, leading to improved wheat PUE and yield compared to chemical fertilizer.

Summary: One alternative for adapting viticulture to high temperatures and the scarcity of water is the development of new grape varieties adapted to such conditions. This study describes the evaluation of six new genotypes derived from different crosses under deficit irrigation and rainfed conditions. The results show significant variation in productivity, phenolic content, and other parameters among the different genotypes, with two genotypes showing noteworthy performance under rainfed conditions and potential for sustainable high-quality viticulture in dry and hot areas.

Summary: This study evaluates the impact of two deficit irrigation strategies on the agronomic and productive parameters of the Menara olive cultivar. The results show that moderate and controlled water stress does not significantly affect the yield of the Menara olive cultivar. By reducing plant water requirement during sensitive and normal periods, it is possible to save irrigation water and increase water productivity with a slight decrease in fruit yield. However, sustained deficit irrigation leads to slower shoot growth and reduced fruit volume.

Summary: The impacts of climate change on food security and the adaptations needed are of global concern. This study focused on arid and semi-arid regions and examined the effects of climate change on maize yield in the Nile Delta. Different maize cultivars were tested and calibrated using crop models, and various adaptation options were considered. The results showed significant reductions in yield for both long- and short-growing cultivars, but the use of stress-resistant genotypes and adjustments in planting date and density could help minimize the potential reduction in yield by the end of the century.

Summary: Novel spatial models for appraising arable land resources using data processing techniques were developed in this study to increase understanding of agroecosystem services. Various methods, including PCA, HCA, AHP, fuzzy logic, and GIS, were integrated to zone and map agricultural land quality in an arid desert area in Egypt. Through satellite imageries, field surveys, and soil analyses, eighteen indicators were defined and reduced to a minimum data set (MDS) using PCA. The original and MDS were weighted by AHP, and eight land quality index maps were generated using GIS. The proposed approach showed good performance in estimating land performance and could provide guidelines for sustainable land-use planning.

Summary: Tropical fruit wastes are important sources of food and nutrition in tropical countries. With the modernization of agriculture, there has been an increase in tropical fruit production, resulting in a higher abundance of fruit waste. Typically, this waste is considered without economic value and ends up in landfills. However, recent observations have shown that tropical fruit waste can be utilized to produce value-added products such as compost, phytochemicals, food products, and biofuels. This review aims to understand the composition of major tropical fruit wastes and their potential for conversion and valorization, including the role of microbes and future perspectives in waste utilization.

Summary: This study examines the effects of shallow groundwater and soil salinity on crop water use in the Nile Delta region of Egypt. Satellite-based evapotranspiration estimation, combined with groundwater and soil salinity data, provides valuable insights in data-scarce areas. The study finds that groundwater depth has a significant impact on evapotranspiration, with shallow groundwater contributing more to crop water requirements. Remote sensing and GIS techniques are important tools for assessing the impact of shallow groundwater and soil salinity on evapotranspiration over large geographic areas.

Summary: Climate change is negatively affecting crop productivity and food security. This study aims to quantify the response of maize yield to projected climate change and suggests adaptation options to counterbalance the impact. The results show that without adaptation, grain yield will be reduced in both spring and autumn seasons, but adopting adaptation strategies can increase grain yield. Therefore, farmers should adopt these strategies to reduce the negative impact of climate change on maize yield.
