A comparison of the isotope-dilution and the difference method for estimating fertilizer nitrogen recovery fractions in crops. III. Experimental
Fertilizer nitrogen (N) recovery fractions may be calculated by the difference or the isotope-dilution method. With the first method an apparent recovery fraction (ARF) and with the latter method a 15N recovery fraction ...
Parameterization and Evaluation of the AquaCrop Model for Full and Deficit Irrigated Cotton
Predicting yield is increasingly important to optimize irrigation under limited available water for enhanced sustainability and profitable production. Food and Agriculture Organization (FAO) of the United Nations addresses ...
Experiment-based prototyping to design and assess cotton management systems in West Africa
Designing innovative combinations of techniques to improve the sustainability of cropping systems in poor countries is a major
challenge. Here, we developed a prototyping methodology to design, assess and adapt a crop ...
Rainfall and temperature effects on lentil (Lens culinaris) seed yield in Mediterranean environments
Lentil (Lens culinaris Medikus) is a rain-fed crop in North Africa and West Asia whose yields are limited by the amount and distribution of rainfall and winter cold. This study aimed to quantify the effects of climatic ...
Analysis of Genotype x Environment Interactions for Grain Yield in Durum Wheat
Genotype x environment (GE) interactions are important sources of variation in crop breeding programs. The objectives of this study were (i) to analyze GE interactions on grain yield of one bread wheat (Triticum aestivum ...
Asymmetric allele-specific expression in relation to developmental variation and drought stress in barley hybrids
P>In the present study, we analysed allele-specific expression (ASE) in the selfing species barley to assess the frequency of cis-acting regulatory variation and the effects of genetic background, developmental differences ...
Correspondence between the Campbell and van Genuchten Soil-Water-Retention Models
Two methods are presented that allow converting the van Genuchten (VG) soil-water-retention (SWR) model parameters to equivalent parameters of the Campbell (C) model. The first method builds on an available solution to ...
Recovery and germination rates of seeds of Mediterranean medics and clovers offered to sheep at a single meal or continuously
Measurements were made of the recovery and germination rates of seed of eight species of annual medic (Medicago spp.) and three of clover (Trifolium spp.) after ingestion by sheep. Recovery of medic seed was measured as ...
Phosphorus Use Efficiency of Wheat Genotypes Grown in Calcareous Soils
Phosphorus (P) deficiency and low P-use efficiency are induced by soil properties, especially in calcareous soils, which are dominant in semi-arid regions of the world such as the Mediterranean region. Alternative approaches ...
Predicting the number of nymphal instars plus new-generation adults of the Sunn Pest from overwintered adult densities and parasitism rates
The present study evaluated the effect of overwintered adult density and egg and adult parasitism rates on the new-generation population densities of the Sunn Pest (Eurygaster integriceps Put.) under field conditions. We ...
