Effects of plant density, nitrogen rate and supplemental irrigation on photosynthesis, root growth, seed yield and water-nitrogen use efficiency of soybean under ridge-furrow plastic mulching

Zhenqi Liao et al.

Summary: The ridge-furrow plastic mulching system can increase soybean yield and water-nitrogen use efficiency. This study reveals the effects of plant density, nitrogen rate, and supplemental irrigation on chlorophyll, photosynthesis, aboveground/root growth, and seed yield, and discovers the relationships among them.

Soybean yield variability per plant in subtropical climate: sample size definition and prediction models for precision statistics

Rafael Rodrigues de Souza et al.

Summary: This study analyzed the effect of the number of sampled plants per experimental unit on experimental precision statistics in soybean yield assessment. The optimal sample size per experimental unit and predictive models for estimating precision were determined. The results showed that as the number of plants measured per experimental unit increased, the confidence interval width of precision statistics decreased, leading to higher precision estimates. It was found that sampling 18 plants per experimental unit was sufficient to reliably estimate most precision indicators. Additionally, the mechanistic response of the confidence interval width could be easily modeled and used to predict experimental precision in highland and lowland cropping systems.

Assessing yield and economic impact of introducing soybean to the lowland rice system in southern Brazil

Giovana Ghisleni Ribas et al.

Summary: The introduction of soybean into the lowland continuous rice system in southern Brazil has shown an increase in rice yield and total income, despite a decrease in overall output due to the rotation. While the soybean-rice rotation has advantages such as lower labor requirements and higher benefit-to-cost ratio, economic risks and constraints from other factors need to be considered.

Soybean grain yield in highland and lowland cultivation systems: A genotype by environment interaction approach

Rafael Rodrigues de Souza et al.

Summary: The study focused on the genotype x environment interaction (GEI) in soybean grain yield, particularly in highland and lowland areas with subtropical climate. The results showed that the complex part of GEI accounted for the majority of variation, while specific genotype adaptability was observed in each environment. The GGE and BLUP techniques demonstrated consistent genotypic ranking.

Spatial frameworks for robust estimation of yield gaps

Juan I. Rattalino Edreira et al.

Summary: The study compared different methods for estimating crop production and enhancing production, finding that estimates from top-down frameworks are uncertain and could benefit from incorporating estimates from bottom-up approaches for more accurate predictions of food security.

Violating the normality assumption may be the lesser of two evils

Ulrich Knief et al.

Summary: The study finds that Gaussian models are robust to non-normal data, with p values remaining reliable in most conditions and showing good power. Parameter estimates are mostly unbiased and precise, except in cases of influential outliers or small sample sizes/highly skewed predictor distributions. Data transformation and visual inspection for outliers and heteroscedasticity are recommended before analysis.
