Remote sensing bears the potential to provide quantitative information of agricultural crops instantaneously and of a certain regional extent. Estimates of crop growth which are used for crop yield prediction, and timing of forthcoming harvest are important in agricultural planning and policy making. For non-optimal growing conditions, estimates of crop growth may be inaccurate. Crop monitoring...

Population growth increases the threat to global food security. Kazakhstan, a major agricultural nation, has made significant contributions world security; however, wide gap exists between its yield and that of other crop-producing countries. Increasing productivity in Kazakhstan through enhancing utilization natural endowments under existing cropland conditions would help alleviate pressure. T...

introduction the global climate is changing and, despite efforts to reduce greenhouse gas emissions, weather variation is inevitable. meanwhile, agriculture as a major water consumer will require adaptation to these variations, along with other challenges, to guarantee its persistence and sustainability. given the arid and semi-arid climate of iran, water, as a main limiting factor for agricult...

Biomass of legumes grown as catch crops improves soil properties and thus soil conditions for following crops. The aim of this study was to evaluate the effect of field pea (Pisum sativum L.) grown as a catch crop and used for green manure on soil properties and yielding of spring barley (Hordeum vulgare L.). Field experiments were conducted in 2008-2011 in the randomized block design with ...

Ensuring stable crop yields in an era where climate change threatens traditional agricultural practices through altered rainfall patterns and increased urban consumption has become a vital concern in global food security. Projected freshwater availability for irrigation indicates that between 20 and 60 Mha of irrigated cropland may have to be reverted to rainfed management [57]. Formerly irriga...

Integrating cover crops (CC) in rotations provides multiple ecological services, but it must be ensured that management does not increase pre-emptive competition with the subsequent crop. This experiment was conducted to study the effect of kill date on: (i) CC growth and N content; (ii) the chemical composition of residues; (iii) soil inorganic N and potentially mineralizable N; and (iv) soil ...

Drought is one of the most severe stresses, endangering crop yields worldwide. In order to select drought tolerant genotypes, access to exotic germplasm and efficient phenotyping protocols are needed. In this study the high-throughput phenotyping platform "The Plant Accelerator", Adelaide, Australia, was used to screen a set of 47 juvenile (six week old) wild barley introgression lines (S42ILs)...

Barley, wheat, rice and maize provide the bulk of human nutrition and have extensive industrial use as agricultural products. The genomes of these crops each contains >40,000 genes encoding proteins; however, the major genome databases for these species lack annotation information of protein subcellular location for >80% of these gene products. We address this gap, by constructing the compendiu...

Drought is one of the most important factors worldwide, which limits crop production, especially in semi-arid areas. The use beneficial microorganisms such as arbuscular mycorrhizal fungi (AMF) may represent an eco-friendly and biological technique to increase crops yields ensure food security. purpose this paper was evaluate effect AMF inoculation on a promised variety hulless barley (Hordeum ...
