Current State and Limiting Factors of Wheat Yield at the Farm Level in Hubei Province

Longitudinal wheat yields in China have declined recent times due to climate change, more frequent natural disasters, and suboptimal agronomic management. To date, it has been unclear which factors predominated yield penalties realised hitherto Hubei Province. This study aimed identify key limiting production across systems agroecological regions, provide a basis for increasing crop while engendering food security. Survey data from 791 households Province were analyzed using descriptive statistics logistic regression. Significant spatial heterogeneity average was observed, with the Jianghan Plain region having significantly lower compared northwest (yield gap: 1125 kg·hm−2). Dryland had higher than rice-rotation 134 575 Socioeconomic factors, cultivation management measures, environmental contributed differently differences. Input costs economic benefits social influencing production. Variation mainly attributed planting methods, soil fertility climatic limited some regions. In northwest, low susceptibility drought high temperatures greater influence on yields. Plain, waterlogging erosion challenges. Waterlogging increased probability of by 8.6 times, severe loss factor almost five. Low-yield farms 21% those northwest. Extreme weather events also Plain. We note significant potential farm-level Province, large existing differences agro-ecological regions modes. Differences practices major driving gaps between modes, meteorological disasters drive regional These results implications aspiring narrow gap increase cereal crops.
