Effects of Reduced Early Post-Sprigging Nitrogen Application on Bermudagrass Sprig Establishment
… week period. We hypothesize that the quantity of nitrogen applied is in excess and that similar 8 to 10 week grow-in can be achieved with less nitrogen especially during the first 4 weeks when there are few plants per unit area. Three interrelated studies were conducted. A "field trial", consists …

Yield and nitrogen uptake of broccoli (Brassica oleracea L. var italica) and soil nitrate status as influenced by rate and timing of nitrogen application
… this study were to amend the current recommended nitrogen rates for broccoli production, and to measure plant N uptake and soil nitrate status throughout the growing season in order to develop an efficient N fertilization program for this emerging industry. A preliminary study in 1985 indicated no …

Sustainable Agronomic Approaches for Reclaimed Wastewater Utilization: A Focus on Phosphorus Removal, Plant Tissue and Soil Nutrients Retention and Leachate Quality using Biochar and Nitrogen Application Rates under Different Forage Systems
… soil pH, cation exchange capacity (CEC), carbon-nitrogen (C:N) ratio, and soil bulk density that can mitigate these limitations for agricultural production in arid and semiarid environments. Improvement of crop productivity has been linked to improved nutrient uptake and efficiency as a result of …

The effect of nitrogen fertilization on protein content and bread baking properties of wheat flour
The effects of variation in nitrogen application during two growing seasons to Coker 916, a soft red winter wheat, on wheat grain and flour protein content and bread baking properties were examined. Nitrogen fertilization regimens tested included the single spring application of 168 kg/ha in growth …

Intensive spring nitrogen management of winter barley: silage and grain yield and composition
The impact of rate and timing of spring nitrogen application on yield and composition of barley forage and grain and the fermentation and utilization of barley silage was investigated in a 3-yr study. The use of a growth regulator, ethephon, was also investigated. Nitrogen application at a rate of …

Strategic applications of nitrogen fertiliser to increase the yield and nitrogen use efficiency of wheat.
In southern Australia a large proportion of crop nitrogen requirements are usually applied early in the season, either just before or at sowing, or during the first 6-8 weeks after sowing. However, the time of greatest demand for nitrogen by wheat crops is during the stem-elongation phase when the …
