Summary: The combined application of biochar and compost significantly increases maize yield and water productivity, saving 40% of water at 60% irrigation level. Cost-benefit analysis shows the highest net benefit with soil organic amendments, indicating the potential of biochar and compost to enhance crop growth and yield even at low irrigation levels.

Summary: This study investigated the eco-physiological and productive response of potatoes to deficit irrigation. It found that, while there were some impacts on the plant's physiology and yield traits, there was no significant decrease in yield compared to normal irrigation. In fact, deficit irrigation improved irrigation water use efficiency.

Summary: This study compares conventional and drought-tolerant hybrids in terms of yield and water-use efficiency under drought conditions in the Texas High Plains region. The results show that drought-tolerant hybrids exhibit lower yield penalties and achieve greater yield gains and water savings through improved water productivity. These findings highlight the potential of drought-tolerant hybrids for increasing yield and conserving water resources.

Summary: Water deficit can reduce maize yield, and it is important to choose appropriate irrigation schemes or strategies to maximize water use efficiency (WUE) for sustainable agriculture. This study evaluated and compared the effects of regulated deficit irrigation (RDI) and partial root-zone drying irrigation (PRDI) on maize plants, and explored the potential of foliar application of glycine betaine (B) and soil-treated chitin (C) for sustainable maize production. The results showed that RDI with 75% field capacity (FC) condition and PRDI treatment improved maize yield and WUE, while PRDI at 50% FC saved water resources.

Summary: Corteva AgriscienceTM conducted a discovery research program to identify biotech leads for improving maize Agronomic Traits, resulting in a diverse set of DNA cassette constructs involving approximately 1671 genes. Field testing of these transformed maize events from 2000 to 2018 demonstrated improved yield in elite maize breeding germplasm. At least 22 validated gene leads with diverse molecular and physiological functions were identified, providing insights for crop improvement in maize and potentially other crops.

Summary: A study in Romania's Transylvanian Plain assessed the agronomic performance of maize under different fertilization gradients. Results showed that fertilization significantly influenced yield, quality, and crop health. Different fertilizer regimes could be used for desired outcomes, but achieving top performance across all agronomic components remains a challenge.

Summary: Currently, maize yields as high as 15.0 Mg ha-1 can be achieved under fully irrigated conditions in China. However, due to water restrictions, exploring appropriate water-saving irrigation methods is crucial. This study tested the effectiveness of deficit irrigation (DI) and regulated deficit irrigation (RDI) in maintaining high grain yield and increasing water productivity (WPc). The experiments were carried out in a maize-producing area in Xinjiang, China, with mulched drip irrigation and dense planting adopted. The results showed that optimized DI and RDI reduced soil water content (SWC) and crop evapotranspiration (ETc), while maintaining high maize yield and increasing WPc and irrigation water productivity (WPI).

Summary: Maize yield in China is significant for global food security, but it faces challenges from extreme weather and increasing demand. Traditional vegetation indexes have limitations in monitoring crop growth. This study proposes a novel method that integrates multiple spectral indexes and temporal aggregation data to estimate maize yield. Results show that the normalized moisture difference index (NMDI) is the most sensitive index, and the integration of multiple indexes improves yield estimation accuracy. The study provides valuable knowledge for yield estimation research.

Summary: Climate variability and land use/land cover change in the northern Ethiopian highlands have been observed to contribute to changes in hydrological extremes. Results show that land use/land cover change has a significant impact on high and low-flow extremes, while climate change has a minor role. The increase in rock area is a major contributor to increased high flow.
