Soybean response and ion accumulation under sprinkler irrigation with socium - rich saline water
The magnitude of crop growth and yield depends on the salinity level, the toxic ions present, and the irrigation system used. In order to study the effect of saline sprinkler irrigation on soybean growth and ionic accumulation in plant tissues a pot experiment was set up. There were three irrigation...

| 520 | |a The magnitude of crop growth and yield depends on the salinity level, the toxic ions present, and the irrigation system used. In order to study the effect of saline sprinkler irrigation on soybean growth and ionic accumulation in plant tissues a pot experiment was set up. There were three irrigation water quality treatments [electrical conductivity [EC] 0, 2, and 4 dS m-1]. Soybean aerial biomass was 25 percent lower than the Control when irrigation salinity was 4 dS m-1. Clearly salinity entering via leaves affected the grain filling stage and severely reduced soybean grain production [80 percent reduction] when salinity in irrigation water surpassed 2 dS m-1. Sprinkler irrigation aggravates soybean's low salinity tolerance and restricts its cropping in such conditions. For early stages two linear relationships between leaf chloride [Cl-] concentration [Y = 14.2-2x] or potassium [K+]/ sodium [Na+] ratio [Y = 5.3x-3.4] and soybean grain yield were found. Both relationships may be used as diagnostic tools for soybean growing under saline sprinkler irrigation. | ||
