Effect of Irrigation Intervals on Soil Salinity and Cotton Yield

Abstract

The effect of irrigation intervals on seed cotton yield at 14 days interval resulted significantly greater cotton yield as compared to 7 and 21 days intervals. The increase in yield was associated to significant increase in branches, total number of productive bolls and yield per plant. The chemical analysis of soil showed little increase in soil pH values, however, decreasing trend in ECe, ESP and SAR was noted in the samples collected after harvest as compared to those collected before sowing.
