Objective: Yield traits are crucial for cotton breeding. Analyzing the yield of terrestrial and exploring their genetic mechanisms through a primary gene + multigene hybrid model provide theoretical basis selecting high-quality varieties identifying associated molecular markers.

Intensive and large-scale drip irrigation plays a crucial role in ensuring cotton production Northwest China. However, significant differences have occurred at times within systems, quantitative information on the importance interactions of factors related to growth constraints is scarce. In 2018–2019, we monitored six possible (irrigation depth, soil texture, salt, moisture, inorganic nitrogen organic matter) associated with management seed yields collective system (CDIS, composed several subsystems (DISs)) southern Xinjiang assess different identify main constraints. 2023, other more refined field trials were conducted further evaluate influencing mechanism crop one typical DIS selected CDIS. The results revealed large yield CDIS; although average was good (2018: 8051 kg ha−1, 2019: 6617 ha−1). Excessive depths (>500 mm) coarse texture (sand content > 70%) identified as constraints, affecting than 45% plant area CDIS based boundary line analysis (a method study responses between variables) from DISs that two directly affected moisture root zone, which reduced effectiveness fertilization under irrigation. Structural Equation Model (used causal relationships among multiple both depth indirectly affect by N uptake critical resisting decline caused An optimized schedule, improved uniformity network adjusted strategies could be used for site-specific address due improve water fertilizer use efficiency management.

Abstract Aims Water deficiency and low water use efficiency severely constrain wheat yield in dryland regions. This study aimed to identify suitable tillage straw management practices improve efficiency, grain of the winter wheat-summer bean double cropping system. Methods A long-term field experiment (onset October 2009) four treatments—plowing with no mulching (PTNS), plowing (PTSM), rotary (RTNS), (RTSM), was conducted at a typical China. The component, dry matter accumulation translocation characteristics, were investigated from 2014 2018. Results significantly increased spike number, grains per spike, 1000-grain weight, harvest index, ultimately resulting increases 10.5% under PT 20.5% RT. Tillage affected characteristics except for that had significant effect on pre-anthesis translocation. Straw respectively consumption by 7.4% 10.4%, 3.1% 9.6%, compared treatments RT without mulching. also enhanced pre-sowing storage capacity, water-saving unit yield. Conclusions TOPSIS confirmed RTSM's superiority through straw-induced improvements nutrient productivity. Rotary optimizes matter/water yield, recommended systems.
