Abstract
A greenhouse experiment with sorghum variety CSH-1 over a period of 90 days was carried out to study the interactive effects of four salinity levels and three N levels on the growth and nutrient composition of sorghum. Chloride to sulphate ratios of 1:3 or 3:1 were maintained at each salinity level. Three levels of N (30, 60 and 90 ppm) as urea were applied at each salinity level. The dry matter production as well as N, P and K concentrations in plants decreased with increasing salinity level, particularly in soils of ECe 8.8 mmhos/cm or more. Increasing N level increased the dry matter production alleviating in part the adverse effect of salinity. Reduction in dry matter production and also in nutrient contents of the plants was more pronounced under chloride- than sulphate-dominant salinity. Higher levels of N application increased the content of N, P and K at all salinity levels
