BACKGROUND The need for reoperation or wound infection treatments between pulsatile and gravity irrigation are statistically equivalent, however, it is unclear which method maximizes operative efficiency and expeditious irrigation. In this study we set out to determine the differences in irrigation rate between these various treatment methods. METHODS This was an ex-vivo experimental laborato...

Irrigation application in cotton crops is traditionally discharged at a constant rate for an entire field. However, not all plants in a crop may require the same amount of water due to the stochastic nature of the crop response and the spatial variability of environmental factors within the field. Control strategies are required to effectively manage spatially and temporally varied irrigation a...

Water deficit stress, permanent or temporary, limits the growth and the distribution of natural vegetation and the performance of cultivated plants more than any other environmental factors. Mechanism involved is still not clear. In order to investigate the effect of different irrigation intervals and anti-transpirants compoundson yield and yield components of Black Cumin (Nigella sativa</e...
