Yield and Forage Quality of the New Forage Perennial Legume Bituminaria bituminosa var. albomarginata cv. Lanza in Response to Rainfall Reduction and Competition J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-21 Jesús Fernández‐Habas, Daniel Real, Tom Vanwalleghem, José Ramón Leal‐Murillo, Pilar Fernández‐Rebollo
Bituminaria bituminosa is a promising drought‐tolerant perennial legume which could reduce the vulnerability of Mediterranean livestock systems to drought. A 3‐year field split‐plot experiment was carried out in southern Spain to test the response of Bituminaria bituminosa cv. Lanza (tedera) to a 24% annual rainfall reduction and competition in terms of yield and forage quality. The experiment included

Waterlogging Effects on Root Morphology, Yield, and Stress Tolerance in Cowpea (Vigna unguiculata L. Walp) Grown on Semi‐Arid Vertisols J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-19 E. Senthamil, Hanamant M. Halli, P. S. Basavaraj, S. S. Angadi, Vinay M. Gangana Gowdra, C. B. Harisha, K. M. Boraiah, B. Sandeep Adavi, S. R. Salakinkoppa, Ganesh Mohite, K. Sammi Reddy
Waterlogging, a global environmental stress, jeopardises food security, causing an economic loss of US$ 74 billion. This could intensify by 14%–35% due to climate change, particularly affecting leguminous crops by altering root morphology and yields. Therefore, studies on the crops root systems and yield reduction to waterlogging stress are required to ensure global food security (sustainable development

Root Lodging Resistance in Maize (Zea mays L.) Under Conservative Strip‐Till Cultivation System J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-17 Ye Sha, Siyu Zhao, Zhanhong Hao, Zheng Liu, Wenlang Hu, Guozhong Feng, Fanjun Chen, Guohua Mi
Root lodging significantly affects maize yield and is influenced by both genotypes and soil characteristics. Strip‐till (ST) is a conservative cultivation method that disturbs only the planting strip, leaving the remaining soil undisturbed and covered with maize residues. Less is known about the effect of ST on root lodging. Here, a field experiment was conducted in Northeast China in 2020 and 2021

Exogenous Melatonin Enhances Pollen Fertility of Drought‐Stressed Cotton (Gossypium hirsutum L.) by Improving Antioxidant Metabolism J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-14 Huilian Yu, Kaiyang Zhao, Ke Yan, Yizheng Wen, Zicheng Gao, Shijie Xue, Wenqing Zhao, Shanshan Wang, Zhiguo Zhou, Wei Hu
Exogenous melatonin (MT) can aid crops in mitigating drought stress, yet its impacts on cotton pollen fertility under drought remain understudied. To address this, a study on the effects of exogenous MT on cotton pollen sterility and internal physiological metabolism under drought stress was conducted. Results showed that although antioxidant enzymes catalase (CAT), peroxidase (POD) and superoxide

The Architecture of Adaptive Lignin Biosynthesis Navigating Environmental Stresses in Plants J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-13 Abdul Jalal, Yongli Wang, Chenyang Cai, Aliya Ayaz, Khulood Fahad Alabbosh, Khalid Ali Khan, Song Han, Daochen Zhu
In natural ecosystems, plants are under continuous environmental stresses, compromising plants' survival and propagation. Being sessile in nature, plants evolved various signalling pathways to cope with adverse changing environments, and to optimise their adaptation to terrestrial conditions. The plant cell wall, rich in polymers, is actively engaged in the signalling process. In this context, the

Leaf and Crown Cuticular Wax Responses in Annual Bluegrass (Poa annua L.) Plants Exposed to Ice Encasement J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-13 Devendra Prasad Chalise, Emily Merewitz
The plant cuticle, the outermost protective layer of most aboveground plant parts, serves as the first line of defence. While its role in various stress responses has been well‐studied, its role in ice encasement stress tolerance is unknown. This research aimed to investigate changes in cuticular wax on the leaves and crowns of annual bluegrass after different ice encasement durations (0, 40, and 60

Late Harvest: Freezing Temperatures Reduce the Root Yield and Sugar Content of Beta vulgaris L. J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-12-04 Lihua Wang, Jingjie Chen, Guokai Fan, Rui Chen, Gui Geng, Yao Xu, Yuguang Wang
Sugar beet (Beta vulgaris L.) is the main source of white sugar in northern China, and an optimal harvesting time is key for maximising its yield and sugar content. The goal of this study was to investigate the effect of gradually extending harvest times on the growth, physiological characteristics, yield and sucrose accumulation in sugar beet and identify the optimal harvesting time. We conducted

Deciphering Rice Genotypes Under Submergence Stress and Optimum Condition for Yield Stability Analysis J. Agron. Crop Sci. (IF 3.7) Pub Date : 2024-11-28 Prajjwal Pradhan, Bimal Das, Deepak Kumar, Victor Phani, Surajit Kundu
In the flood‐prone area, the improved high‐yielding variety of rice declines its vegetative growth and suffers substantial yield losses due to water stagnation. To address the issue measurement, the present work implemented 45 rice genotypes in a randomized complete block design with three replicates over three consecutive years (2018–2021) across submergence (E1, E3, E5) and optimum environments (E2
