Abstract
In field trials at Brawley, California, sorghum cv. Asgrow Double TX and Northrup King NK-265 were sown on silty clay in mid-May 1982, given adequate N and P fertilizer and irrigated with saline water (1:1 NaCl and CaCl2) of electrical conductivity 1.5-12.1 dS/m. Grain yield was unaffected by soil salinity up to 6.8 dS/m, but each subsequent increase in salinity of 1 dS/m reduced yield by 16%. Yield reduction was due primarily to a decrease in grain weight/ear rather than to a reduction in ear formation. Grain yield of Double TX was significantly higher than that of NK-265. Vegetative growth was less affected by soil salinity than was grain yield. Salinity up to 8.2 dS/m did not affect germination. Higher salt levels delayed germination but did not affect the final germination percentage. Sorghum was more salt tolerant at germination than at later growth stages
