Abstract The increasing frequency of dry periods in many regions the world and problems associated with salinity irrigated areas frequently result consecutive occurrence drought on cultivated land. Currently, 50% all irrigation schemes are affected by salinity. Nutrient disturbances under both reduce plant growth affecting availability, transport, partitioning nutrients. However, can differentially affect mineral nutrition plants. Salinity may cause nutrient deficiencies or imbalances, due...
Abstract Knowledge on short‐term and long‐term availability of nitrogen (N) after application organic fertilizers ( e.g. , farmyard manure, slurry, sewage sludge, composts) provides an important basis to optimize fertilizer use with benefits for the farmer environment. Nitrogen from many often shows little effect crop growth in year application, because slow‐release characteristics organically bound N. Furthermore, N immobilization can occur, leading enrichment soil pool. However, this...
Abstract: Arbuscular mycorrhizal fungi alleviate drought stress in their host plants via the direct uptake and transfer of water nutrients through fungal hyphae to plants. To quantify contribution plant uptake, a new split-root system was designed employed on barley grown loamy soil inoculated with Glomus intraradices under well-watered conditions growth chamber 14-h light period constant temperature (15 °C; day/night). Drought were initiated 21 days after sowing, total eight 7-day drying...
Although the mechanisms of salt tolerance in plants have received much attention for many years, genotypic differences influencing still remain uncertain. To investigate key physiological factors associated with wheat and their relationship to stress, 13 genotypes from Egypt, Australia, India, Germany, that differ tolerances, were grown a greenhouse soils 4 different salinity levels (control, 50, 100, 150 mm NaCl). Relative growth rate (RGR), net assimilation (NAR), leaf area ratio (LAR),...
Precision phenotyping, especially the use of image analysis, allows researchers to gain information on plant properties and health. Aerial detection with unmanned aerial vehicles (UAVs) provides new opportunities in precision farming phenotyping. has created a critical need for spatial data density. The number reflects not only final field emergence but also more precise assessment yield parameters. aim this work is advance UAV analysis as possible high-throughput phenotyping technique. In...
The depletion of fresh water resources leads to the utilisation various alternative sources water, such as seawater. In this regard, foliar application proline is one shotgun approaches increase plant stress tolerance. A pot experiment was conducted in wire house National Research Centre, Dokki, Cairo, Egypt, during winter season 2010–2011. consisted three concentrations (0, 25 and 50 mM) two diluted seawater (3.13 6.25 dS m− 1), whereas control plants were irrigated with tap (0.23 1)....
Salinity decreases yield in arid and semi-arid areas. With increasing demand for irrigation water, alternative sources are being sought. Seawater salinity was previously considered unusable irrigation. However, this water can be used successfully to grow crops under certain conditions. Amino acids is well known biostimulant which has positive effects on plant growth yield, significantly mitigates the injuries caused by abiotic stresses Therefore, present study, effect of exogenously...
Phosphorus (P), a plant macronutrient, must be adequately supplied for crop growth. In Germany, many soils are high in plant-available P; specifically arable farming, P fertilizer application has been reduced or even omitted the last decade. Therefore, it is important to understand how long these can support sustainable production, and what concentrations of soil required it. We analyzed 36-year long-term field experiment regarding effects different liming rates on growth with rotation sugar...
Abstract Legumes' sensitivity to salt is exacerbated under growth conditions requiring nitrogen fixation by the plant. Phosphorus (P) deficiency widespread in legumes, especially common bean ( Phaseolus vulgaris L). To examine performance of P. stress conditions, a field experiment was conducted using two recombinants inbred lines (RILs) 115 (P‐deficiency tolerant) and 147 susceptible), grown different salinity levels (L) (1.56, 4.78, 8.83 dS m −1 as LI, L2, L3, respectively) supplied with...
