Agronomy Journal, Volume 118, Issue 1, January/February 2026.Abstract Phosphorus (P) is essential for maize (Zea mays L.) growth but is a limited and non‐renewable resource. Studies using DSSAT CSM‐CERES‐Maize remain scarce for low‐P soils. This study assessed maize yield response to P fertilization in P‐deficient soils using an adapted version of the DSSAT CSM‐CERES‐Maize model with minor code modifications to ...

Impact of calibration strategy and data on wheat simulation with the DSSAT‐Nwheat model
Agronomy Journal, Volume 117, Issue 4, July/August 2025.Abstract Cropping system models (CSMs) are valuable tools for analyzing genotype, environment, and management (G × E × M) interactions in crop production. To apply a CSM in a new region with specific soils, climate, and cultivars, proper calibration and evaluation are required.

Genetic dissection of maize phenology using an intraspecific introgression library [PDF]
, 2011 Background: Collections of nearly isogenic lines where each line carries a delimited portion of a donor source genome into a common recipient genetic background are known as introgression libraries and have already shown to be instrumental for the ...

Plant Pathology, Volume 74, Issue 4, Page 1152-1167, May 2025.Epidemiological model shows that dose splitting increases selection for fungicide resistance, especially for partial resistance mechanisms that only affect efficacy at lower fungicide concentrations. ABSTRACT Fungicide resistance management principles recommend that farmers avoid splitting the total dose applied of a fungicidal mode of action (MoA ...

Variability of Phyllochron, Plastochron and Rate of Increase in Height in Photoperiod-sensitive Sorghum Varieties [PDF]
Annals of Botany, 2008 West African sorghum (Sorghum bicolor) varieties are generally highly photoperiod-sensitive, which is a necessary adaptation to the variable onset date of the rainy season and the variable dates of sowing in the savannah zone. Depending on sowing date, plants can produce from 12 to >40 leaves on the main culm, with height varying from 1 m to more than ...

Soybean seed yield distribution within the canopy as affected by nitrogen supply
Crop Science, Volume 65, Issue 2, March/April 2025.Abstract Soybean (Glycine max [L.] Merr.) seed yield is influenced by the seasonal availability of resources (i.e., nutrients, light, and water). While nitrogen (N) supply is becoming a soybean yield‐limiting factor, the N‐induced effect in seed yield components is still unclear.
