Solution cultures were used to study the importance of P absorption during various growth stages of spring wheat and intermediate wheatgrass. Phosphorus was not needed in the solution cultures during all growth phases of the two crops. A supply of P for the first 5 weeks (up to heading for ...

Understanding the availability of irrigation water at various growth stages is crucial for guiding agricultural scheduling in arid areas with limi
Data from a field experiment with 14C pulse-labelling of spring wheat at different development stages, were used to estimate rhizosphere carbon fluxes. Not only the flux of C to the roots was assessed but also the fluxes of organic and inorganic release of root-derived material. C fluxes were...

Canopy temperatures in differentially irrigated plots (36 3 m) were measured by infrared thermometry at midday from growth stages of heading to maturity. Net radiation, wind speed, humidity, and air temperature data were collected. Neutron meter measurements were used to calculate ET. Summations of...
Aerial (aboveground biomass) whole plant samples of irrigated HRS wheat were collected from the field at 16 growth stages and separated into leaves, stems, heads, and grain for dry matter determinations and analyzed for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (...
(NTech Industries, Ukiah, CA) for measuring in-season N status on spring wheat. Five N rates were applied pre-plant as ammonium nitrate. Sensor readings and plant biomass samples were collected at Feekes 6 and Feekes 10 growth stages. The sensor measures reflectance in the red and near ...
