Article
In the semiarid pampas region of Argentina, peanut (Arachis hypogaea L.) crop undergoes frequent and unpredictable drought stress periods, with high probability of occurrence under future climate change projections. However, the overall frequency of occurrence and timing of different drought stress patterns under current and future climates has not...
Article
Including winter canola (Brassica napus L.) crop into cereal-based crop rotations can diversify the current agricultural systems in the United States (US). In addition, canola can help to satisfy market demand for plant-based edible oil, thus better understanding of oil productivity of canola in the US production areas is relevant for further study...
Article
Understanding physiological changes in response to long‐term selection for yield can inform breeding decisions and hasten genetic gain. The objective of this study was to characterize changes over time in yield‐relevant physiological traits for hybrids with different years of release for grain sorghum (Sorghum bicolor L. Moench). Field trials were...

Pearl millet (Pennisetum glaucum R. Br.) water-limited yield gap in Senegal is estimated at 2.2 Mg ha⁻¹. Proper variety and management selection are critical to the sustainable intensification of millet systems. The objectives of this study were to assess the effect of two pearl millet varieties and different crop management (plant density-nutrient...
Article
The determination of critical nitrogen (N) dilution curves (CNDCs) has been the subject of intensive study for the last decades due to its relevance to diagnosing crop N status. However, to date, minimum steps, data requirements and robust science-based guidelines to estimate CNDCs based on experimental data have not been formalized in the literatu...

Full-text available
More than a half-century after the initial conceptualization of nitrogen use efficiency, crop improvement progress for direct nitrogen gains remains an elusive target. A more relevant conceptual framework bridging soil and plant processes is needed for crop improvement and environmental stewardship. In this Comment, Ciampitti et al. introduces a mo...
Article
One of the main challenges of using low plant densities in restrictive and variable environments is to maximize the use of resources in better‐than‐expected years. The adoption of prolific genotypes has addressed part of this problematic, through an increase in reproductive plasticity. However, tillering could be an alternative to increase reproduc...
Article
Full-text available
Livestock farming is a livelihood activity and is critically important for the food and nutritional security of the majority of the population in West African countries, including Senegal. Nevertheless, livestock farming operates far below the optimum production potential, mainly due to demographical, biophysical, economic, environmental, and socio...
Article
Symbiotic nitrogen (N) fixation (SNF) is critical to satisfying the nutritional need of soybean (Glycine max (L.) Merr.) and maintaining productivity and high seed protein concentration. Due to its low environmental impact, a key factor for increasing the sustainability of soybean systems is to enhance SNF. Seed inoculation with the free-living Azo...

Nitrogen management is central to the economic and environmental dimensions of agricultural sustainability. Yield response to nitrogen fertilisation results from multiple interacting factors. Theoretical frameworks are lagging for the interaction between nitrogen and air temperature, the focus of this study. We analyse the relation between yield re...
Article
The critical nitrogen (N) dilution curve (CNDC) (Nc = A1W-A2) and the N nutrition index (NNI) have shown to be a robust diagnostic tool to assess crop N status. Several CNDCs were established for potatoes (Solanum tuberosum L.) in various conditions. However, it is difficult to know if these different CNDCs reflect a true variability across genotyp...
Article
CONTEXT: Soil salinity is the main environmental limiting factor for current agricultural farming systems in the Bangladesh coastal zone. Targeting crop selection to ameliorate its impact in food production is a priority to ensure food security, diversifying crop outputs and reducing smallholders' vulnerabilities. In this context, crop growth model...
Article
Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction in the year-to-year yield variation. However, breeding efforts in this region have been focused on early sowing date environ...
Article
Legumes play a key role in the sustainable intensification of agricultural systems, improving biodiversity, ecosystem services, and reducing the dependency of food production on nitrogen (N) fertilizers. This review aims to: (i) quantify seed yield per kg of total aboveground N and fixed aboveground N, (ii) study the N derived from the atmosphere (...
Article
Studies at a regional scale suggest that although maize yield increased substantially, sensitivity to water deficit also increased concurrently with crop improvement. This study assessed changes in yield and yield stability after two decades of breeding by evaluating two cohorts of hybrids released by the AQUAmax(R) program, and comparing them to a...
Article
Owing to the high contents of oil and protein, soybean [Glycine max L. (Merr.)] seeds are energy-rich. Genetic improvement of soybean yield is linked to the dilution in seed protein; changes in low-energy compounds such as carbohydrates have received less attention. We tested the hypothesis that selection for yield in soybean has shifted seed compo...
Article
The soybean [Glycine max (L.) Merr.] compositional quality is mainly provided by the seed concentration of protein and oil. These traits are critical for sustaining global use, and although there is demand for high protein soybean, no mechanism to differentiate production is in place. At the opposite end of the supply chain, farmers are remunerated...
Article
Full-text available
Limited knowledge about how nitrogen (N) dynamics are affected by climate change, weather variability, and crop management is a major barrier to improving the productivity and environmental performance of soybean-based cropping systems. To fill this knowledge gap, we created a systems understanding of agroecosystem N dynamics and quantified the imp...
Article
With the growth of population, climate change is a threat to global food security. Understanding and identifying appropriate options of cropping systems and management practices at spatial (locations) and temporal (climate change) scale is important and required.

A simulation model Decision Support System for Agrotechnology–Cropping Systems Model (DSSAT–CSM) was used to identify optimum level of agronomic practices for growing wheat ( Triticum aestivum L.) in sandy loam soils in northern Ethiopia, and to assess impacts of climate change and management strategies on wheat yields. The model was calibrated for...
Preprint
Soybean ( Glycine max L. Merril) seed costs have steadily increased over the past decades and triggered a growing interest in reducing seeding rates, while improving profitability via seed savings and better yields. However, little is known on the implications of early-season spatial plant-to-plant uniformity on soybean yield under the current redu...
Article
Over the past century of maize (Zea mays L.) breeding, grain yield progress has been the result of improvements in several other intrinsic physiological and morphological traits. In this study, we describe (i) the contribution of kernel weight (KW) on yield genetic gain across multiple agronomic settings and breeding programs, and (ii) the physiolo...

We re-analyzed a dataset of biomass (W) and plant N concentration (%N) of tall fescue (Festuca arundinacea Schreb.) using a Bayesian statistical model for esti...
Article
The most widely used approach for prescribing fertilizer nitrogen (N) recommendations in maize (Zea Mays L.) in Argentina is based on the relationship between grain yield and the available N (kg N ha − 1), calculated as the sum of pre-plant soil NO 3-N at 0− 60 cm depth (PPNT) plus fertilizer N (N f). However, combining covariates related to crop N...

Nitrogen (N) metabolism is a major research target for increasing productivity in crop plants. In maize (Zea mays L.), yield gain over the last few decades has been associated with increased N absorption and utilization efficiency (i.e. grain biomass per unit of N absorbed).
