The interaction effects of irrigation amount and water salinity on yield, ETa and WUE were statistically insignificant in the experiments.
The attributes considered include salinity, water yield, nitrogen run-off, phosphorus run-off, stream sediment concentrations, soil erosion and carbon sequestration.
The effect of irrigation water salinity on yield was significant in the 2011/2012 growing season and non-significant in the 2012/2013 growing season (p < 0.05).
Because of the salinity, maximum yields of vegetable crops are not possible, but better yields could be obtained if proper attention were given to leaching and more frequent irrigation.
The assimilation of temperature and salinity fields yields a too vigorous ventilation of the thermocline and the deep ocean, whereas the inclusion of CFC-11 and radiocarbon improves the representation of physical and biogeochemical tracers and of ventilation time scales.
For example, when irrigation water exceeds 5 ppt salinity, crop yields decrease as much as 50% [8].
Among these variables, salinity alone yielded the highest coefficient with 100x ecoregional data (rho = 0.761, Table 4b).
The interaction effects of irrigation volume and water salinity on grain yield, TWU, WP, WPirrig and soil salinity were statistically non-significant.
Several lines showed desirable traits such as high yield, salinity tolerance, early maturity, good plant type, and resistance to pests and diseases.
However, long-term effects of brackish water irrigation and straw mulching on soil salinity and crop yield need to be further evaluated for sustainability of the system.
