Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Evaluation of CERES‐Maize Model for Predicting Yield, Evapotranspiration, Water Productivity and Drought Stress Indices Under Center Pivot, Subsurface Drip and Furrow Irrigation Systems With Different Irrigation Levels Simultaneously

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Yield, Evapotranspiration, Production Functions, Crop Coefficients, Water Productivity and Soil‐Water Extraction of Three Watermelon Varieties

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT While watermelon is an important commodity in the United States and worldwide, some of the fundamental watermelon productivity indices (crop evapotranspiration [ETc], transpiration [Tr], evaporation [E], ET‐yield production functions [ETYPF], basal crop coefficients [Kcb], crop water productivity [CWP], soil‐water extraction [SWE]) have not ...
