Special Issue Information

Dear Colleagues,

Wheat (Triticum aestivum L.) is one of the most essential crops worldwide. Increasing wheat yields without increasing additional investment is a global challenge aimed at producing sufficient food for a growing human population. Mechanisms and approaches that aim to achieve the high yield and high efficiency of wheat have gradually become the focus of crop science research.

This Special Issue aims to gather new information on the mechanism of wheat growth and yield formation, the utilization law of water and fertilizer in wheat, and means of cultivating high-yield and -efficiency wheat cultivation.

Specifically, this Special Issue calls for original research, reviews, and small-scale reviews of the methods and mechanisms of wheat productivity and resource utilization, including, but not limited to, the mechanism of yield formation and resource utilization in wheat; the regulation effects of population distribution, water and fertilizer management, growth regulation, and other measures on wheat yield improvement and efficient resource utilization; the mechanism of stress restricting yield formation and resource utilization in wheat and its stress resistance measures; and intelligent production modes for achieving both high yield and efficiency in wheat cultivation.

Increased aboveground biomass is contingent on enhanced photosynthetically active radiation intercepted by the canopy (IPAR), improved radiation use efficiency (RUE), or both. We investigated whether and how optimized agronomic management practices promote IPAR and RUE. Four integrated agronomic management treatments, i.e., local traditional practice (LP), improved local traditional practice (ILP), high-yield agronomic management (HY), and improved high-yield agronomic management (IHY), were compared over two wheat (Triticum aestivum L.) growing seasons. The average grain yield obtained with IHY was 96% relative to that of HY and was 7% and 23% higher than that with ILP and LP, respectively. Both HY and IHY consistently supported large values of the leaf area index and IPAR fraction, thereby increasing total IPAR. Treatment HY showed increased pre-anthesis RUE, manifested as a higher specific leaf nitrogen content and whole-plant N nutrition index at anthesis. The highest pre-anthesis aboveground biomass was obtained with HY due to the highest pre-anthesis IPAR and RUE. Along with a higher canopy apparent photosynthetic rate, IHY produced higher post-anthesis aboveground biomass due to its higher post-anthesis IPAR and RUE. Treatment IHY had a slightly lower total IPAR but a similar total RUE and harvest index, thus producing a slightly lower grain yield relative to HY. These results demonstrate that the optimized agronomic management practice used under IHY effectively enhances radiation capture and improves radiation utilization. Additionally, the net profit for IHY was higher than that for HY, ILP, and LP by 8%, 11%, and 88%, respectively. Considering the high grain yield, high RUE and high economic benefits, we recommend IHY as the agronomic management practice in the target region, although further study of improvements in pre-anthesis RUE is required.
