Abstract
Pot experiments were done at Nursery of University of Gujrat, Pakistan in 2011 for the study of Na2SO4 effect on maize (Zea mays L.) at growth stage. 32-B-33 Pioneer variety of maize was used. The pot experiment was arranged in a completely randomized design with four salt concentrations and four replicates under the greenhouse condition. Sulfate treatments were applied to maize by dissolving Ammunion sulphate salts in distilled water. There were four levels of Na2SO4 (0, 50 mM, 100 mM and 150mM) used on growth of plant. The experimental soil was salinized with Na2SO4 at the rates of 0, 50, 100 and 150mM Na2SO4. Growth of the maize plants was inhibited by salinity. Enhancements of growth were observed at 50mM Na2SO4 in maize. The strongest inhibition of growth occurred at the high salt concentration (150mM). Applied Na2SO4 significantly decreased dry mass of maize plants. All the growth attributes such as root and shoots lengths and plant fresh weight decreased with increase in salinity levels. It was observed that salinity had adverse effect on growth of maize. It was concluded that water potential changes caused reduction of root length and leaf area in maize under salt stress. Water potential changes caused by salt concentrations in growth medium and salinity had adverse effect in growth.
