COMPARISON OF BARLEY GROWTH IN NATURALLY AND ARTIFICIALLY SALINIZED SOILS

Open full text 3 citations

Abstract

An experiment was conducted under controlled conditions to compare the growth of barley in naturally and artificially salinized soils. In two Chernozem soils, a Whitney clay loam and a Cavendish sandy loam, the decline in barley yield per unit increase in salinity was the same in naturally and artificially salinized treatments. These findings suggest that artificially salinized soils accurately simulate the effects of naturally saline soils in their effect on barley growth. The results further substantiate previous findings that growth response to salinity appears to be related to the availability of calcium in the soil. Key words: Calcium, salinity, Chernozem
