Resin extractable Mo explained 72% of the variation in yield of wheat (Triticum aestivum) grown on ten acid soils as measured by the relative yield of the tops or by the uptake of Mo by the youngest emerged blade.

Abstract Large distribution of roots in topsoil layers allow more uptake soil water and nutrients during the vegetative growth, but it may be disadvantageous if deficit develops reproductive stage. The relationship between (0–0.4 m) use, dry matter nitrogen (N) accumulations, grain yield was examined winter wheat (Triticum aestivum L.) with contrasting root size topsoil. Two old landraces (CW13...

High variability due to soil heterogeneity and climatic conditions challenge measurement of greenhouse gas (GHG) emissions as influenced by management practices in the field. To reduce this variability, we examined the effect of management practices on CO2, N2O, and CH4 fluxes and soil temperature and water content from July to November, 2011 in a greenhouse. Treatments were incomplete combinat...

Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plantsgenerally suffer from water stress during heading and reproductive stages. This research wascarried out at the experimental farm of the faculty of agriculture, Kafrelsheikh University usingtwo water treatments (water stress and well-watered), four N levels (0, 80, 160 and 240 kg ha-1)and two ascorbic acid le...

Abstract Soil P testing has been widely used to predict crop yields, uptake, and fertilizer demands in agriculture. Diffusive gradients thin films (DGT) provides a zero-sink soil test which mimics diffusion-controlled plant uptake previously found availability crops better than conventional quantity-based tests highly weathered Australian, though not European soils. Here we tested the performan...

the objective of this study was to estimate genetic parameters and to investigate the type of gene action in controlling androgenesis in wheat. two wheat cultivars of grebe and houtman were reciprocally crossed with two synthetic genotypes of do1 and pol and then a complete set of the parents, f1, reciprocal f1 (rf1), f2 and back-cross generations (bc1 and bc2) of each cross were used for anthe...

Quantitative and Qualitative Evaluation of Spring Bread Wheat (Triticum aestivum L.) Cultivars under Different Planting Dates

Aim. The goal of this work was to study the effect drought in critical phase ontogenesis on growth and productivity breed winter wheat plants (Triticum aestivum L.). Methods. Wheat cultivars Darunok Podillya Podolyanka were grown under optimal nutrition well-water conditions until earing-flowering phase, after that experimental transferred regime for 8 days, water supply restored end vegetation...
