CO2 elevation and N fertilizer supply modulate leaf physiology, crop growth and water use efficiency of maize in response to progressive soil drought J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-02-19 Manyi Zhang, Guiyu Wei, Bingjing Cui, Chunshuo Liu, Heng Wan, Jingxiang Hou, Yiting Chen, Jiarui Zhang, Jie Liu, Zhenhua Wei
Elevated atmospheric CO2 concentration (e[CO2]) and varied nitrogen (N) fertilization levels may mediate the different responses of C4 crops to progressive soil drought. In this study, the effects of reduced N (N1, 0.8 g pot−1) and adequate N (N2, 1.6 g pot−1) supply on leaf physiology, plant growth and water use efficiency (WUE) of maize (C4 crop) exposed to progressive soil drought grown at ambient

Regional detection and assessment of chilling damage on maize considering land surface temperature, crop growth status and solar radiation changes J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-02-05 Jingxiao Zhang, Jiabing Cai, Di Xu, Hongfang Chang, Baozhong Zhang, Zheng Wei
Increased frequency and severity of chilling damage events pose potential risks to crop performance and productivity due to climate change. Accurate and real-time access to chilling damage is important for crop growth and yield stability based on field's actual environment. To precisely identify regional chilling events and evaluate the impacts on crops, this study presents a model to estimate field

Warm-season turfgrass species genotype-by-environment interaction for turfgrass quality under drought J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-01-18 Beatriz Tome Gouveia, Ambika Chandra, Kevin E. Kenworthy, Paul L. Raymer, Brian M. Schwartz, Yanqi Q. Wu, Susana R. Milla-Lewis
One of the biggest challenges the turfgrass industry is currently facing is limitations of available water for irrigation of turfgrass areas. Efforts on breeding for drought resistance have increased over the past several years across the United States. Thus, the objectives of this study were to evaluate the performance of bermudagrass (Cynodon spp. Rich.), St. Augustinegrass (Stenotaphrum secundatum

Tall fescue tiller survival over summer in a subtropical environment: The role of the size and depth of root systems J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-01-16 J. M. Jáuregui, D. F. Michelini, G. H. Sevilla, G. Berhongaray, G. D. Berone, J. Baudracco, P. Chilibroste, M. G. Agnusdei, F. A. Lattanzi
Pasture persistence is a key determinant of the economic and environmental performance of pastoral animal production systems. Large and deep root systems that help resist summer water stress have been proposed as a relevant trait for vegetative persistence of perennial temperate forage species growing in subtropical climates or under future climatically challenging scenarios. In a previous study [Jauregui

Enhancing wheat yield and nitrogen use efficiency in the Huang-Huai-Hai region of China: Insights from root biomass and nitrogen application responses J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-01-16 Tiantian Huang, Maoxue Zhang, Pengfei Dang, Wen Wang, Miaomiao Zhang, Yanyu Pan, Xiaoping Chen, Yuncheng Liao, Xiaoxia Wen, Xiaoliang Qin, Kadambot H. M. Siddique
Wheat yield and nitrogen use efficiency (NUE) have improved simultaneously with the genetic development of wheat varieties. However, wheat selection is carried out routinely in N-rich field conditions, with breeding progress limited under low soil available nitrogen. Thus, we performed a 2-year field investigation using eight milestone winter wheat varieties released between 1947 and 2017 in the Huang-Huai-Hai

Leaf photosynthetic performance is not a key factor affecting grain yield in spring wheat subjected to heat and combined heat and drought stresses J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-01-16 Søren Gjedde Sommer, Xiangnan Li, Eva Rosenqvist, Fulai Liu
The yield traits and physiological responses of three wheat genotypes were studied when subjected to heat and combined heat and drought stress at anthesis under either aCO2 (400 ppm) or eCO2 (800 ppm) in a greenhouse. The heat treatment was 7-days at day/night 35/28°C, and the combined heat and drought was withholding irrigation from the heat-stressed plants until the photosynthetic rate reached <5 μmol m−2 s−1

Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-01-16 Facundo Tabbita, Karim Ammar, María Itria Ibba, Francisco Andrade, Marco Maccaferri, Maria Corinna Sanguineti, Roberto Tuberosa, Carlos Guzmán
In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the effects of heat stress on quality traits and identifies which glutenins (Glu-1, Glu-2 and Glu-3 loci) alleles are the most important to obtain high gluten strength under optimal and
