Crop models and their use in assessing crop production and food security: A review
Crop models allow a better understanding of crop production response to diverse conditions. They assess crop production and food availability, crucial parts of food security. Their outputs support farmer and shareholder responses to adaptation and mitigation. AbstractAgriculture is directly related to food security as it determines the global food supply. Research in agriculture to predict crop productivity and losses helps avoid high food demand with little supply and price spikes. Here, we review ten crop models and one intercomparison project used for simulating crop growth and productivity under various impacts from so...

Forecasting spring maize yield using vegetation indices and crop phenology metrics from UAV observations
In this study, we predicted maize yield using canopy vegetation indices (VIs) and crop phenology metrics obtained through UAV with ordinary least squares (OLS), stepwise multiple linear regression (SMLR) and gradient-boosted regression tree (GBRT). The results reveal that the VIs extracted from UAV imagery had a high correlation with yield (R = 0.92), facilitating crop yield estimation. Additionally, coupling crop phenology significantly improved the prediction accuracy of SMLR, with the highestR2 and lowest RMSE of 0.894, 1.238 × 103 kg ha−1, respectively. But, the enhancement of GBRT by this method was sl...

Intercropping medicinal plants is a new idea for forage production: A case study with ajowan and fenugreek
In this study, the impact of different cropping patterns and fertilizer sources on the forage yield and quality of ajowan (Carum copticum L.), fenugreek (Trigonella foenum-graecum L.), and pea (Pisum sativum L.) was investigated. The findings shed light on the importance of biofertilizer application as a sustainable solution for enhancing forage production and quality in agricultural systems. AbstractBiofertilizers has potential to improve crop productivity in a sustainable manner yet their impact on forage crops yields and forage quality indices have not been extensively explored. In this study, the impact of different cr...

Asparagine and nitric oxide jointly enhance antioxidant capacity and nitrogen metabolism to improve drought resistance in cotton: Evidence from long ‐term field trials
This study investigates the interaction between asparagine (Asn) and nitric oxide (NO) on cotton's drought tolerance. The combined treatment of Asn and sodium nitroprusside (SNP) improved plant growth, yield, and nitrogen content, while also increasing irrigation water productivity under water-limited conditions. These results suggest that Asn and SNP can be useful tools for sustaining cotton production under drought conditions and supporting the global supply of cotton for the textile industry. AbstractAsparagine (Asn) and nitric oxide (NO) can enhance plant tolerance to abiotic stress, but their interaction is not well u...

Phenotyping and identification of target traits for de novo domestication of wheat wild relatives
AbstractDe novo domestication —the modification of domestication genes in crop wild relatives via genome editing—is an approach for harnessing the beneficial genetic diversity of crop wild relatives. A prerequisite for de novo domestication is phenotyping to identify genetic materials suitable for cultivation in the respecti ve environment. Taxa from the wheat genepool (Triticum aestivum,Triticum durum,Triticum monococcum) are a staple food; these taxa comprise wild relatives of different ploidy levels. The diploidTriticum boeoticum andTriticum urartu and the tetraploidTriticum dicoccoides andTriticum araraticum harbor...

Reviving grain quality in wheat through non ‐destructive phenotyping techniques like hyperspectral imaging
AbstractA long-term goal of breeders and researchers is to develop crop varieties that can resist environmental stressors and produce high yields. However, prioritising yield often compromises improvement of other key traits, including grain quality, which is tedious and time-consuming to measure because of the frequent involvement of destructive phenotyping methods. Recently, non-destructive methods such as hyperspectral imaging (HSI) have gained attention in the food industry for studying wheat grain quality. HSI can quantify variations in individual grains, helping to differentiate high-quality grains from those of low ...

Analysis of the transcriptome and metabolome reveals phenylpropanoid mechanism in common bean (Phaseolus vulgaris) responding to salt stress at sprout stage
In this study, transcriptome and metabolome analyses were conducted on local common bean variety under salt stress at the sprout stage for a period of 0, 12, and 24 h. Results showed that phenylpropanoid pathways (including phenylpropanoid biosynthesis and phenylalanine metabolism) and flavonoid pathways (including flavonoid biosynthesis and flavone and flavonol biosynthesis) played an important role in controlling responses to salt stress as evidenced by an alysis of differentially expression genes, common expression patterns, WCGNA, and differentially altered metabolites (DAMs) analyses. In addition, exploration of th...

Optimal tree architecture for high ‐yield yellowhorn (Xanthoceras sorbifolium) management
AbstractTree architectural attributes demonstrate a significant association with fruit yield. Yellowhorn is the future bioenergy tree in China; however, the species suffers from high reproductive energy and exceedingly low reproductive output. To optimize yellowhorn management and pinpoint priority trees featuring optimal architecture, we employed machine learning modeling to develop high fruit yielding predictive models using five yield indicators (dependent variables: FrW, SeW, ShW, FrW, and SeN) and five tree characteristics (independent variables: CA, TH, DGL, HLC, and MBN) of yellowhorn. Results showed that trees char...

Long ‐term soybean–maize rotation experiments in cereal‐based farming systems at Bako, Western Ethiopia
AbstractMaize monoculture is one of the major restrictions limiting maize productivity in Western Ethiopia. Although the inclusion of legumes in cropping systems is an essential approach for the sustainable management of farming systems and for reducing the nitrogen (N) fertilizer requirement for maize production in the long term, the effects of soybean on the sustainability of maize productivity and soil fertility are unclear in Ethiopia. Continuous cropping of maize has led to extensive degradation of soil and a decrease in crop productivity in Western Ethiopia. Thus, the study was conducted to compare the long-term impa...

The role of genetic diversity and pre ‐breeding traits to improve drought and heat tolerance of bread wheat at the reproductive stage
We reported important marker-trait associations for sustainable grain production under drought and heat stress at anthesis. Likewise, the mechanisms of drought and heat resilience including gene expression and physiological traits (activities of carbohydrate metabolic and antioxidant enzymes, and endogenous hormonal responses) were explored. Moreover, identified pre-breeding traits and genotypes can be utilized in breeding new wheat cultivars resilient to future adverse environments. AbstractExtreme weather including heat waves and drought episodes are expected to increase in intensity and duration due to climate change. W...

Dual ‐purpose crops for grain and fodder to improve nutrition security in semi‐arid sub‐Saharan Africa: A review
This review synthesized published data on production systems, importance of DP varieties, the trade-off among grain and biomass uses, and the opportunities/challenges of growing DP varieties from cowpea, pearl millet, and sorghum. Findings showed that DP crops and varieties were largely grown by smallholder farmers in a variety of soil and climatic conditions with production systems characterized by large gaps between attainable and actual crop yields which varied significantly among regions. The DP varieties have greater potential to mitigate the land use competition between human food and animal feed and are a sustainabl...

Processing overwhelms biostimulant ‐induced vitamin E improvement in lentils
It was found that quality traits such as vitamin E composition and contents in raw lentils could be improved by caffeine applications used as a biostimulant, but positive effects were overwhelmed by lentil processing (cooking). AbstractAlthough biostimulants are used in crop cultivation to improve productivity and/or quality of fruit and vegetables, their effect is rarely investigated up to processed food. Here, we investigated whether vitamin E content in lentils can be influenced by caffeine used as a biostimulant in a greenhouse-controlled experiment, and how cooking influences its intake in our diet. Results showed tha...
