Dryland wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor (L.) Moench) are often grown using a wheat–sorghum-fallow (WSF) crop rotation on the semiarid North American Great Plains. Precipitation stored during fallow as soil water is crucial to the success of the WSF rotation. Stubble mulch-tillage (SM) and no-tillage (NT) residue management practices reduce evaporation, but the sp...
Development of alternative livelihoods has become a popular policy to uplift the socioeconomic status of small-scale fishers and to reduce fishing pressure on overexploited fisheries. Seaweed farming has been incorporated into many community-based coastal resources management projects and fisheries management initiatives as an alternative livelihood option for fishers in tropical developing cou...
Salinisation is a major environmental problem affecting land and water systems in Australia. This paper outlines a study currently being undertaken to provide a new tool to manage salinity from environmental and socioeconomic perspectives. In this study, biophysical and socio-economic aspects of the Little River Catchment and their relevance to salinity management will be investigated using a B...
A supervised feature selection algorithm was applied to determine the most important features contributing to wheat grain yield. Four hundreds seventy two fields (as records) from different parts of Iran which were different in 21 characteristics (features) were selected for feature selection analysis. Selection of the wide range of features, including location, genotype, irrigation regime, fer...
Dryland farming in the Mediterranean climate of the Pacific Northwest, USA supports extremely low earthworm populations under conventional tillage. Increases in earthworm populations are being observed in fields under no-till cropping systems. A 30+ year experiment with four tillage levels in a pea (Pisum sativum L.)-winter wheat (Triticum aestivum L.) rotation was evaluated for earthworm popul...
Land-ownership patterns in rural areas are undergoing changes. To explore the critical question of how changing land ownership in a watershed potentially drives land use, we examined differences in individual landowners’ reasons for owning drylands. We conducted a mail survey of 767 landowners in three counties of central Texas, USA. Using exploratory factor analysis we reduced motivations into...
the west asia-north africa region, which is characterized by a typical mediterranean climate, is the center of origin of cereals, notably wheat (triticum spp.) and barley (hordeum spp). however, cereal production, which is primarily rainfed, is mainly constrained by drought due to the low rainfall accompanied by high temperatures. cereals have been tradi-tionally grown following a fallow period...
applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...
To evaluate the spatial and temporal soil water availability (SWA) and improve the soil water use efficiency in agriculture, this study established a new index system for SWA evaluation considering the soil storage capacity, the temporal and spatial matching degree between soil water supply and crop water demand, and the soil water transformation and utilization efficiency. To quantitatively ca...
Grain number is a major trait for wheat yield under dryland farming. An International Triticeae Mapping Initiative (ITMI) mapping population comprising 105 recombinant inbred lines (RIL) developed from a cross between a Synthetic hexaploid wheat (Triticum aestivum) 'W7984' and a spring wheat variety 'Opata M85' was used to identify quantitative trait loci (QTL) associated with grain number per ...
