“…Quantitative analysis of biomass accumulation dynamics using model equations is an important method for investigating crop yield formation. Related studies have been reported in crops such as rice (Ji et al, 2012;Li et al, 2010), wheat (Villegas et al, 2001), cotton (Overman & Scholtz, 2013), maize (Meade et al, 2013), and soybean (Nakano et al, 2021;Van Roekel & Purcell, 2014). For example, Wei (Wei et al, 2021) quantitatively analyzed the biomass accumulation dynamics of different rice variety types after transplant based on the Gompertz equation.…”

Field experiments were performed in 2019 and 2020 to explore yield performance and biomass accumulation dynamics for different direct-seeded rice methods after wheat straw return. The experimental treatments included two direct-seeded rice methods (dry direct-seeded rice and wet direct-seeded rice) and two wheat straw return treatments (with and without wheat straw return). Wheat straw return had a negative impact on the yield and biomass of direct-seeded rice. Compared with wet direct-seeded rice, dry direct-seeded rice was more negatively affected, with yield and biomass reduced by 6.7%-7.6% and 5.4%-6.5%, respectively. The yield loss was mainly associated with insufficient total spikelet numbers caused by reduced panicle numbers. A lower maximum tiller number caused by the restricted seedling tillering capacity was partly responsible for the inadequate panicle numbers in direct-seeded rice after wheat straw return. Wheat straw return reduced the maximum and average rate of biomass accumulation, shortened the duration of effective biomass accumulation, and delayed the days to achieve the maximum rate of biomass accumulation for direct-seeded rice. The negative effect of wheat straw return on direct-seeded rice was concentrated mainly in the early stage; reduction in the average biomass accumulation rate in the early stage accounted for 61.1%-75.3% of the reduction in total average rate. Wet direct-seeded rice had a higher average rate and amount of biomass accumulation at the early stage, a greater maximum tiller number, as well as a stronger photosynthetic ability and grain filling ability after heading, which contributed to improving panicle number and total spikelet number, ultimately increasing yield and biomass compared with dry direct-seeded rice. These results demonstrate that wheat straw return reduced yield and biomass, mainly by inhibiting growth in the early stage of direct-seeded rice. However, the wet direct-seeding method decreased the losses in yield and biomass after wheat straw return.

Crop models have suggested high sensitivity of soybean [Glycine max (L.) Merr.] to day length and the resultant extension of the growth period as a concept to overcome yield loss due to climate warming. However, experimental validation of this concept is incomplete. The E3 and E4 loci encode phytochrome A isoforms and enhance sensitivity to day length. Our previous study showed that the dominant E4 allele can mitigate yield loss due to warming. In this study, we similarly tested the hypothesis that the dominant E3 allele can reduce yield loss caused by warming. One of the leading Japanese cultivars Enrei (e3/E4) and near‐isogenic lines (NIL‐e3e4, NIL‐E3e4, and NIL‐E3E4) in the Enrei genetic background were grown at near ambient temperature or either 2.0°C or 4.7°C above ambient temperature in temperature‐gradient chambers (TGCs) in a cool region in Japan. The number of days from sowing to beginning of flowering (R1) decreased with increasing temperature, regardless of genotype. However, increasing temperature extended the period from R1 to beginning of pod filling (R3) and increased pod number per plant and seed yield per plant in all genotypes except NIL‐e3e4. Combined data from the TGC experiment and from field trials across three different latitudes showed that the decreased developmental rate during the R1–R3 period can be attributed to longer days, rather than by supra‐optimal temperatures. We conclude that E3, in addition to E4, could potentially increase seed yield in cool regions under future warming.
