Titre de série : Transactions of the ASAE Titre : Irrigation corn grain sorghum with a deficient water suplly Type de document : texte imprimé Auteurs : Stewart, R. D. ; Pruitt, W. O. ; Hagan, R. M. Année de publication : 1975 ISBN/ISSN/EAN : CI-03610 Note générale : "Maximizing crop production with limited irrigation water requires quantitative information about differential yield responses to give levels of water deficit in each major growth period. The pollination period of corn is widely thought of as a ""critical period"" in this regard. Our fondings support the idea that corn grain yield is especially vulnerable to water deficits during the pollination perod, provided the crop has experienced little or no ET deficit in the late vegetative period, ending at first tassel. However we find the susceptibility of corn yield to deficits in the pollination period to be greatly lessened if there has been prior deficits. Crop yield prediction when water is limiting requires a quantitative expression of the ET deficit impact on yield."
