Monthly changes in net photosynthetic rate ( , (a)) and instantaneous water use efficiency (WUE, (b)) irrigated with canalwater and varying levels of municipal effluents during 1998-99 and 1999-00. Error bars are ±SE. , T2, , and are irrigation of seedlings with municipal effluent at PET, 1 PET, 2 PET, and canal water at 1 PET, respectively.
