After over 20 years of practicing shallow rotary tillage combined with straw direct return in the middle and lower Yangtze regions of China, the yield potential has gradually disappeared, and new alternative tillage practices are required to continuously increase rice yield. This paper investigates the yield effect and mechanism of deep tillage combined with straw return through two consecutive years

Coordinating lodging incidence and grain yield through wheat genetic diversity Field Crops Res. (IF 5.6) Pub Date : 2024-06-28 Xiang Kong, Guishen Zhao, Xinran Sun, Yuhui Fu
Lodging is a complex phenomenon that affects wheat grain yield worldwide. There is a contradiction between lodging incidence and continuous increase in grain yield in a single-cultivar pattern. However, few studies have explored the coordination between lodging incidence and grain yield with an increase in genetic diversity. This study tested the hypothesis that positive intra-population interactions

Optimizing bioenergy sorghum productivity and nutrient removal in Illinois: Impact of nitrogen fertilization under diverse marginal conditions Field Crops Res. (IF 5.6) Pub Date : 2024-06-25 Chunhwa Jang, Jung Woo Lee, Nictor Namoi, Jinwook Kim, Moon-Sub Lee, Daniel Crozier, Wendy Yang, William Rooney, D.K. Lee
Bioenergy sorghum ( L. Moench) is a promising crop for contributing to the United States bioenergy supply. However, the varying limitations of the marginal lands targeted for its cultivation present a management challenge. This two-year study aimed to investigate how the limitations associated with marginal cropland impact the effects of nitrogen fertilization on the yield of bioenergy sorghum and

Defoliation level and timing affect popcorn yield traits in the Midwestern United States Field Crops Res. (IF 5.6) Pub Date : 2024-06-25 Victor Emmanuel de Vasconcelos Gomes, Corinne Lee, Alexander Lindsey, Wanderson Novais, Nasib Koirala, Mark Zarnstorff, James Houx, Justin McMechan, Osler Ortez, Elliot Knoell
Popcorn [ (L.) var. Everta] is an important field crop in the Midwestern United States. However, hailstorms are a major threat to ensuring high yield because of their effects on leaf photosynthesis, pollination, and stalk lodging. A multi-state study spanning six site-years (2020–2023) was conducted in two locations (Ohio and Nebraska) to determine how defoliation intensity at different stages affects

Post-heading accumulation of nonstructural carbohydrates and nitrogen in rice (Oryza sativa L.) roots Field Crops Res. (IF 5.6) Pub Date : 2024-06-20 Kazuaki Onoda, Reina Ohta, Mchuno Alfred Peter, Raphael Edifor, Masaru Hamajima, Ayaka Mae, Asaka Murai, Makoto Kondo, Nobuhito Sekiya
Roots are plant organs that absorb nutrients and water. While roots serve as sink organs for nutrients in perennial and woody plant species, the dynamics of nutrient accumulation in roots for annual plant species, particularly in crop species like L. (rice), are not well understood. Japanese rice cultivars bred for whole-crop silage exhibit large aboveground biomass and a notably small number of spikelets

Establishing a water-use boundary function for potato through crop modeling Field Crops Res. (IF 5.6) Pub Date : 2024-06-20 Funian Zhao, Qiang Zhang, Jun Lei, Kai Zhang, Heling Wang, Runan Jiao, Huiyan Wu
The yield to water-use boundary function is a valuable method for estimating attainable yield and yield gap (the difference between attainable yield and actual yield) in water-limited regions. However, the water-use boundary function for potato has not been clearly defined yet. In current research, we established a water-use boundary function for fresh potato tubers in a climatic transition zone (Longzhong
