The use of genome-wide association studies (GWAS) to detect quantitative trait loci (QTL) controlling complex traits has become a popular approach for studying key traits in crop plants. The goal of this study was to identify the genomic regions of barley (Hordeum vulgare L.) that impact five agronomic and one quality trait in U.S. elite barley breeding lines, as well as to identify markers tig...

Seasonal changes in the levels of soil microbial biomass C (MBC) and N (MBN), N-mineralization rate and available-N concentration were studied in rice±barley supporting tropical dryland (rainfed) agroecosystem under six combinations of tillage (conventional, minimum and zero tillage) and crop residue manipulation (retained or removed) conditions. Highest levels of soil MBC and MBN (368±503 and ...

Crop wild relatives (CWR) are a good source of useful alleles for climate change adaptation. Here, 19 durum wheat, 24 barley, and lentil elites incorporating CWR in their pedigrees were yield tested against commercial checks across environments located Morocco, Ethiopia, Lebanon, Senegal. For each crop, the combined analysis variance showed that genotype (G), environment (E), x (G×E) effects si...

Dryland cereals and legumes  are important crops in farming systems across the world.  Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and...

Conservation agriculture (CA) is becoming increasingly attractive to farmers due advantages such as lower production costs and less destruction of soil structures compared the conventional tillage. The cultivars introduced for systems may not be suitable under CA environments, newly adapted need developed. Accordingly, four separate field experiments were conducted over two cropping seasons (20...

Dryland forest resources have great socio-economic and ecological importance in countries of SSA by playing significant roles in livelihood diversification of both rural and urban households, wood and food security, providing animal feed, human health care and environmental conservation. Despite their great importance, these resources have been subjected to severe degradation, owing to several ...

in this research, geographical information system (gis) and analytical hierarchy process (ahp) were applied to agricultural land use suitability of aq-qala township for barley cropping in rainfed condition. for this purpose, 17 environmental layers of the study area collected, and thematic maps such as slope, elevation, precipitation, average, minimum and maximum temperatures and some of micro ...

a 2-years (2007-2009) field study was carried out at the college of agriculture, shiraz university, to evaluate the influence of crop residues management and nitrogen (n) rates on soil quality and barley grain protein under dryland conditions. the experiment was conducted as strip split plot with four replications. horizontal plots were three crop residues rates (0, 750 and 1500 kg ha-1), verti...

Clustering was used to divide dryland farming areas in western Iran into homogeneoussub-regions to identify dryland farming potential, considering drought impacts. Clusteringutilized eight algorithms/four indices to detect optimal number of clusters. Ward’s algorithmvalidated by Silhouette index, produced the best result by detecting 7 dryland farming clusters.Based on similar P/ETo values, fou...
