New approach combining food value with nutrient budgeting provides insights into the value of alternative farming systems
The production of protein, fat, starch and sugar was combined with the balance of nitrogen (N), phosphorus (P) and potassium (K) into an overall measure of nutrient use efficiency of human macronutrient production in six different rotational farming systems. N use efficiency was lower than P or K, and combining synthetic fertiliser use with organic amendment applications raised food production significantly. Legume-supported rotations without livestock produced more protein, starch and sugar per unit area than those with livestock. AbstractSustainable farming systems provide food for humans while balancing nutrient managem...

Effects of a one ‐time application of controlled‐release nitrogen fertilizer on quality and yield of rice
This study find a suitable or optimal CRNF strategies to achieve improvements in both yield and quality of rice. Results from this study provides empirically supported recommendations for improving rice yield and quality through N fertilizer management. AbstractLimited information is available on the influence of a one-time application of controlled-release nitrogen fertilizer (CRNF) in improving both yield and quality of rice. In this study, two rice cultivars, Jia58 (J58) and Jia67(J67), were used to study the effects of six combinations of short-acting (40 –60-day release periods) and a long-acting (80–120-day relea...

A soybean GmDREB3 gene contributes to drought tolerance in wheat
GmDREB3 greatly increased drought tolerance in wheat plants along with improved physiological and agronomic traits and grain yield AbstractDREB transcription factor can significantly improve the plant resistance to drought, high salt, low temperature, high temperature, and other abiotic stress. A previous study showed that DREB transcription factor geneGmDREB3 from soybean can improve drought resistance in tobacco, however, whether it can improve drought resistance in wheat needs to be further investigated. In the present study,GmDREB3 was transferred to a wheat variety, Shi366 and two positive lines of the T5 generation w...

Differences in rice yield and biomass accumulation dynamics for different direct seeding methods after wheat straw return
We performed a 2-year field study to assess the effect of wheat straw return on dry and wet direct-seeded rice, and we modeled biomass accumulation using the Richards equation. Wheat straw return reduced the yield and biomass of direct-seeded rice, and this effect was greater for dry direct-seeded rice. Wet direct-seeded rice showed a higher rate and amount of biomass accumulation at the early growth stage, as well as higher tiller numbers, which improved panicle numbers and total spikelet numbers and thereby increased yield compared with dry direct-seeded rice. AbstractField experiments were performed in 2019 and 2020 to ...

A new convergent science framework for food system sustainability in an uncertain climate
Transforming food systems in ways that ensure healthy and sustainable diets for all requires bold novel actions that support evidence-based polices, investment, and decision making. New approaches that link different forms of science together and engage stakeholders as partners, while connecting those science multipliers with policy innovations in the real world, are required. Convergence science can meet this demand by addressing systemic interdependencies and synergies, as well as catalyzing actionable solutions for food systems transformation. AbstractThe complexity and interconnectivity of food systems and climate requ...

European consumer and societal stakeholders' response to crop improvements and new plant breeding techniques
In this study, we engaged with consumer experts and societal stakeholders to consider their perceptions, expectations, and acceptability of improving crops and NPBTs for f uture-proofing the agri-food systems. AbstractThe global demand for providing nutritious, sustainable, and safe diets for a 10 billion population by 2050 while preserving affordability, reducing environmental impacts, and adapting to climate change will require accelerating the transition to sustainable agri-food systems. A plausible way to help tackle these challenges is by developing new plant varieties that have impro ved crop yield, plant nutritio...

Transcriptome and metabolome integration in sugarcane through culm development
Sugarcane (Saccharum sp.) is a tropical and subtropical C4 plant with a high photosynthetic and carbon assimilation efficiency that stores sucrose. This high-yielding grass, high in sucrose and lignocellulosic biomass, is considered an optimal feedstock as an alternative to fossil fuels and to produce a broad range of high-value biomaterials. Multi-omics correlation analysis was used to generate a global view of the essential metabolic pathways identifying critical genes involved in carbon partitioning during different stages of development. AbstractSugarcane (Saccharum sp.) is a tropical and subtropical C4 plant with a hi...

Perspective on the present state and future usefulness of marama bean (Tylosema esculentum)
Marama bean has potential as a food security crop in arid regions. The steps needed for it to be domesticated to provide uniform individuals for farmers to grow are detailed. The possibility of a value-added chain for growers aside from the food product is also considered. AbstractRecent focus on indigenous knowledge of plant species that have long been consumed by mankind, but not having a prominent place in organized agriculture, has raised the profile of what steps are needed to bring such potentially useful plant species into formal agriculture practice. Many of these orphan plants have been cultivated, albeit usually ...

Productivity and global warming potential of direct seeding and transplanting in double ‐season rice of central China
Direct-seeded, double-season rice (DDR) using ultrashort-duration cultivars achieved 15.1 t ha-1 of annual yield within 188 days.Yield performance of DDR was comparable to that of transplanted double-season rice (TDR).Shifting from DDR to TDR significantly reduced GWP and GHG intensity by 28.9-53.2% and 20.7-63.8%, respectively. AbstractLabor and water scarcity requires crop establishment of double-season rice to be shifted from traditional transplanting to direct seeding. Owing to the limited thermal time, only ultrashort-duration cultivars of about 95 d can be used for direct-seeded, double-season rice (DDR) in central C...

Investigating how COVID ‐19 has challenged the Eurocentric concept of ‘development’: a case for sustainable food systems in the UK
The COVID-19 pandemic reinforced the reality that the UK's Food system is unsustainable The findings provide a unique insight on the UK food system from a Global development lens. Bridges the gap between pre-pandemic literature and emerging post-pandemic research. The research encourages new innovative ways to conceptualise and measure Development. AbstractThe COVID-19 health crisis has imposed extensive shocks to many global systems, particularly the UK food production chains, further challenging Eurocentric development discourses and stereotypes. Thus, this paper investigates how the pandemic has challenged the UK's deve...

Modelling the impact of improved photosynthetic properties on crop performance in Europe
Using the GECROS model, we simulated the effect of improvements in photosynthesis on a range of growth parameters. The responses were modelled using climate data collected over a 10-year period (1991 –2000) from 66 sites around Europe. Improvements in photosynthesis did result in increases in yield. The greatest increases were obtained for increases inJmax andκ2LL (up to an average 11% increase for total plant biomass), and these increases were found across all Europe. Increases in both these parameters have a predominant effect on the light-use efficiency for subsaturating irradiances. Improvements in other parameters ...
