Relationship between Phosphorus and Nitrogen Concentrations in Spring Wheat
Efficient management of P in crop production requires the development of tools to quantify the P status of plants. Our objectives were to establish the relationship between P and N concentrations of spring milling wheat (Triticum aestivum L.) during the growing season and, in particular, to determine the critical P concentration required to diagnose P deficiency. Shoot biomass and P and N ...

Evaluation of the AquaCrop model for simulating yield response of winter wheat to water on the southern Loess Plateau of China
The objective of this study was to evaluate the performance of the FAO-AquaCrop model in winter wheat in the southern Loess Plateau of China. Multi-year field experimental data from 2004 and 2011 were used to calibrate and validate the model for simulating biomass, canopy cover (CC), soil water content, and grain yield under rainfed conditions. The model performance was evaluated using root ...

Measuring grain protein concentration with in-line near infrared reflectance spectroscopy
The advent of near infrared (NIR) on-combine sensors gives growers the opportunity to measure the grain protein concentration of wheat (Triticum aestivum L.) during harvest. A study consisting of three sequential experiments (laboratory bench, combine test stand, and field) was conducted to evaluate the performance of an in-line, NIR reflectance spectrometer, referred to as the ProSpectra Grain ...

Selecting Zinc-efficient wheat genotypes with high grain yield using a stress tolerance index
There is no reliable indicator for identifying Zn-deficiency tolerant genotypes with high grain yield. The aim of this investigation was to compare the grain yield response of 30 spring and 20 winter bread wheat (Triticum aestivum L.) genotypes to Zn fertilization under field condition and to select high grain yield Zn-deficiency tolerant genotypes using a stress tolerance indicator. The stress ...
