Synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants The concept of synchronization energy and protein was first by Jhonson, Implying that maximum microbial protein synthesis could be achieved by matching the rate of Organic Matter and protein degradation. Synchronization of rumen available...

BACKGROUND Lack of accounting for proton uptake and secretion has confounded interpretation of the stoichiometry of photosynthetic growth of algae. This is also problematic for achieving growth of microalgae to high cell concentrations which is necessary to improve productivity and the economic feasibility of commercial-scale chemical production systems. Since microalgae are capable of consumin...

A field experiment was carried out at the Didactic and Experimental Farm in Swadzim near Poznań in 2004-07. Two maize cultivars were studied, six nitrogen doses and magnesium doses. The effects of the mentioned factors exerted on the utilization of nitrogen from the applied mineral fertilizer and on the nitrogen harvest index were studied. The impact of nitrogen fertilization on the mineral int...

A three-dimensional, process-based model of the ocean’s carbon and nitrogen cycles, including C and N isotopes, is used to explore effects of idealized changes in the soft-tissue biological pump. Results are presented from one preindustrial control run (piCtrl) and six simulations of the Last Glacial Maximum (LGM) with increasing values of the spatially constant maximum phytoplankton growth rat...

In the Mediterranean region, careful management of water and nitrogen utilization is required to achieve high crop yields in a sustainable and economic way. Prediction models are useful tools for deriving site/region–specific optimum management strategies for irrigation and nitrogen use. Yield-SAFE, a simple and robust model for growth and resource use in agroforestry systems, simulates crop yi...

Genetic improvement is the fundamental basis for improving nitrogen-use efficiency. A better understanding of genetic factors controlling nitrogen uptake and utilization is required for crop genetic improvement. In this study, we identified the quantitative trait loci (QTLs) associated with traits of nitrogen uptake and utilization by using the single-sequence repeat marker method and a recombi...

Twelve different tomato (Lycopersicum esculentum Mill.) genotypes were grown in a controlled greenhouse to determine the influence of genotype variation on the efficiency of nitrogen utilization and fruit yield. The results showed that the variation of genotype in tomatoes influences the utilization and assimilation of foliar NO3. The genotypes that proved highly efficient in this utilization w...
