Optimal drip irrigation leaching amount and times enhance seed cotton yield and its stability by improving soil chemical environment and source-sink relationship Field Crops Res. (IF 5.6) Pub Date : 2024-08-08 Chao Xiao, Fucang Zhang, Yi Li, Junliang Fan, Xintong Xu, Xiaoqiang Liu
The arid and semi-arid regions of northwest China play a pivotal role in the national cotton production. However, soil salinization poses a severe constraint on seed cotton yield in this region. Salt leaching by drip irrigation has become increasingly popular for ameliorating saline-alkali soils. Yet, the most effective approach for utilizing drip irrigation leaching to maximize cotton productivity

Genotypic differences in the agronomic performance of ratoon rice in a cool-temperate environment in central Japan Field Crops Res. (IF 5.6) Pub Date : 2024-08-08 Weiyi Xie, Chika Furusawa, Haruna Miyata, Syed Tahir Ata-Ul-Karim, Yuji Yamasaki, Fumitaka Shiotsu, Yoichiro Kato
The major challenge for the rice–ratoon-rice system in cool-temperate environments is to ensure high ratooning ability from stubbles after harvesting of main rice crops. The choice of locally adapted cultivars with high ratooning ability is crucial for this system. We aimed at identifying modern ultrashort-duration cultivars with high ratoon rice yield in central Japan (35°N to 36°N), which represents

Effects of poly-γ-glutamic acid on soil pore structure, maize grain filling, yield and water use efficiency under mulched drip irrigation Field Crops Res. (IF 5.6) Pub Date : 2024-08-07 Zhongmin Zhai, Wenjuan Shi, Lu Liu, Bo Jing
Poly-γ-glutamic acid (γ-PGA) is a biodegradable and non-toxic and harmless water retention agent, contributing significantly to in the sustainable development of agriculture. This study focused that investigated effect of γ-PGA on soil pore structure, maize growth, grain filling characteristics, maize yield and water use efficiency under mulched drip irrigation, and the optimal application strategy

Farming shallow soils: Impacts of soil depth on crop growth in the Everglades Agricultural Area of Florida, USA Field Crops Res. (IF 5.6) Pub Date : 2024-08-05 Xue Bai, Samuel J. Smidt, Yuchuan Fan, Trista Brophy, Young Gu Her, Noel Manirakiza, Yuncong Li, Jehangir H. Bhadha
Over half of the US's sugarcane production comes from the Everglades Agricultural Area (EAA) in Florida (USA). However, the loss of organic soils due to oxidation, which results in the gradual reduction of soil depth, poses a significant concern for the future of agriculture throughout the EAA. Understanding the relationship between soil depth and crop production in the EAA is critical to developing

Improving rice yield and water productivity in dry climatic zones of West Africa: Season-specific strategies Field Crops Res. (IF 5.6) Pub Date : 2024-08-05 Jean-Martial Johnson, Mathias Becker, Elliott Ronald Dossou-Yovo, Kazuki Saito
Irrigated lowland systems contribute most to rice production in sub-Saharan Africa and play a critical role in meeting the increasing rice demand. However, in dry areas of West Africa, negative effects associated with climate change and widespread water scarcity hamper efforts to increase the productivity of irrigated rice. Quantifying rice yields and water productivity and identifying the drivers

Forage boost or grain blues? Legume choices shape Kernza intermediate wheatgrass dual-purpose crop performance Field Crops Res. (IF 5.6) Pub Date : 2024-08-01 Priscila Pinto, Stefania Cartoni-Casamitjana, David E. Stoltenberg, Valentin D. Picasso
Kernza intermediate wheatgrass is a new perennial grain crop with the potential to produce high nutritive value forage when intercropped with legumes. Understanding the potential benefits of intercropping systems requires considering the interaction between different legume species intercropped, intermediate wheatgrass row spacing, and environments encompassing spatial and temporal variation. We aimed

Crop nitrogen status and yield formation: A cross-species comparison for maize, rice, and wheat field crops Field Crops Res. (IF 5.6) Pub Date : 2024-07-31 Ignacio M. Rodriguez, Josefina Lacasa, Gilles Lemaire, Ben Zhao, Syed Tahir Ata-Ul-Karim, Ignacio A. Ciampitti
The utilization of crop nitrogen (N) status as an in-season diagnosis tool for predicting N needs to maximize grain yield (GY) is a well-established concept in agronomy. However, a cross-species comparison including the characterization of yield components, grain number (GN) and grain weight (GW), to understand the physiological basis behind the GY-crop N status relationship is still missing. The main

Maize breeding effects on grain yield genetic progress and its contribution to global yield gain in Argentina Field Crops Res. (IF 5.6) Pub Date : 2024-07-29 J.I. Amas, F. Curin, K.E. D' Andrea, S.F. Luque, M.E. Otegui
Maize production in Argentina has increased in recent years, following the global gain (GG) in grain yield (GY). The GG in GY depends on genetic progress (GP), which requires frequent quantification to detect potential plateaus and variations in its contribution to the GG. In this sense, hybrid adoption in Argentina shifted from double- and three-way to single cross (F1) hybrids in the 1990s, thereby

Managing interspecific competition to enhance productivity through selection of soybean varieties and sowing dates in a cotton-soybean intercropping system Field Crops Res. (IF 5.6) Pub Date : 2024-07-29 Qingqing Lv, Jianlong Dai, Kedong Ding, Ning He, Zhenhuai Li, Dongmei Zhang, Shizhen Xu, Cundong Li, Baojie Chi, Yongjiang Zhang, Hezhong Dong
Productivity and benefits in intercropping systems are influenced by the overlapping period and competitive dynamics between species, which are contingent upon variety selection and planting schedules. However, there is limited research on improving the productivity of intercropping systems by adjusting sowing dates for combinations with minimal plant height differences. A two-year field experiment
