Synopsis

Synopsis

Yields increased with increasing P fertilization but decreased with increasing salinity. At the highest saline level vine yields at the high P level were twice those of the no-P treatment, and pod yields were 21/2 times greater. Evapotranspiration per unit weight of leaves decreased with increasing salinity and increasing P fertilization. Decreases in pod yields with increasing N were attributable to the increased salinity caused by the nitrate fertilizer added. N had no effect on evapotranspiration. Salinity significantly affected both the N and P contents of the plant.
