Summary: In the natural environment, plants are exposed to various abiotic and biotic stresses simultaneously or sequentially. However, little is known about the combined effects of these stresses on plants. This study investigated the effects of soil compaction and drought on maize hybrids through measurements of gas exchange, chlorophyll fluorescence parameters, leaf area, leaf greening, leaf water deficit, leaf water potential, and membrane injury. The results showed that high soil compaction led to a decrease in most measured traits, while drought had a greater impact, especially on sensitive hybrids. The study also revealed the genetically determined variability of tolerance to these stresses and suggested potential criteria for hybrid selection.

Summary: Improving maize performance in both well-watered and water-limiting conditions can benefit from enhancing the physiological trait networks governing water and carbon flux, rather than focusing on individual traits independently.

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: A study was conducted on two maize hybrids with similar growth but different physiological responses to investigate lipid remodeling strategies in response to repeated drought events. Differences in adaptability, especially in galactolipid metabolism and fatty acid saturation patterns, were observed during recovery, which may lead to membrane dysregulation in the sensitive hybrid. The more drought-tolerant hybrid showed more changes in metabolites and lipids, despite a lower physiological response, while the sensitive hybrid had higher responses but lower significance on the level of individual lipids and metabolites. This study highlights the importance of lipid remodeling during recovery in drought response.

Summary: The study aimed to identify maize hybrids with high and stable yields under different soil moisture regimes, conducting trials at seven test environments in two locations in India. Various methods including AMMI, GGE biplot, and MTSI were used to analyze the phenotypic stability of maize hybrids, with an emphasis on identifying genotypes with high stability and maximum yield potential. The methods employed were effective in identifying promising maize hybrids with high mean performance and greater phenotypic stability across different soil moisture conditions.

Summary: Pearl millet is a C-4 crop grown in the tropics and subtropics of the Indian subcontinent and sub-Saharan Africa for its grain and stover. The increasing intensity of drought due to climate change necessitates a greater focus on breeding for drought tolerance in pearl millet. Advances in genomics and molecular biology have provided tools to enhance the development and delivery of high-yielding and drought-tolerant cultivars.

Summary: The study addresses different physiological adaptive responses to drought stress among maize hybrids, revealing that hybrids with higher recovery potential may be more important than those investing more in tolerance mechanisms. Only one hybrid in the study was able to maintain biomass production under drought conditions, and in the scenario of a long drought intermitted by a water-pulse, strategies involving resistance mechanisms or high recovery potential were equally effective.

Summary: In the semiarid Texas High Plains, the grain yield of maize is greatly reduced when irrigation cannot meet water requirements. Drought-tolerant hybrids can mitigate yield losses resulting from water deficits. This study found that by concentrating irrigation on less land area and optimizing planting rates, yield reductions under limited irrigation capacities can be minimized.

Summary: In this study, the effects of irrigation capacity and planting density on maize water use were examined. The results showed that irrigation level significantly influenced the seasonal change in soil water storage, with a significant decrease in soil water under low irrigation capacity at harvest. Stored soil water within the examined depth increments were similar among different maize hybrids and planting densities, indicating a limited effect of drought-tolerant traits on transpiration.

Summary: This study demonstrates that diversifying crop rotations with small grain cereals and cover crops can alleviate maize water stress and reduce drought losses by 17.1%. Crop rotation diversification is an underappreciated drought management tool to adapt crop production to climate change through managing for soil organic matter.

Summary: This article highlights the importance of selecting appropriate hybrids, dosing macro- and micronutrients, and evaluating energy and economic efficiency in corn cultivation for biogas production. The study presents the results of a 3-year field research on different maize hybrids grown for silage, analyzing the impact of nutrient application on yield, composition, methane production, and economic efficiency. The findings demonstrate that the use of macro- and micro-fertilizers can significantly increase maize yield, and the application is economically viable at a certain biomethane price.

Summary: This study advances the cognitive framework in maize breeding by quantifying the impact of N availability on grain N demand and remobilization capacity in two hybrids, as well as formalizing the interaction between N and WSC remobilization. Additionally, it highlights the importance of maintaining a balance between N and WSC remobilization for optimal grain growth and yield improvements in maize.
