چکیده
Soil salinization is more aggravating than ever before and techniques are needed to mitigate this problem; understanding salinity-fertilizer relationship of considerable economic importance for promoting crop growth productivity in saline soil. A pot experiment was done a greenhouse determine whether the N could alleviate negative effect different salts compositions on growth, physiological attributes two most used Sudan sorghum (Sorghum bicolor (L.) Moench) cultivars (Wadahmed Tabat). The plant subjected salt stress at 0, 0.3419 M NaCl, 0.1408 Na2SO4, four levels application 4, 8, 12 g kg-1 soil, designated as N0, N1, N2, N3, respectively. Results showed that Na2SO4 reduced height, leaf area index, number leaves, dry weight (DW), chlorophyll a, total content, increased soluble protein activities peroxidase (POD) catalase (CAT) by 16.4%, 29.7%, 61.5%, 28.7%, 39.6%, 12.7%, 99.7%, 34.3%, 51.8%, respectively, when compared with non-saline treatment. had harmful NaCl. This study revealed fertilizer successful alleviating adverse impacts both types salt. In study, soil effective measured parameters cultivars. These findings demonstrated amendment impact salinity. âWadahmedâ tolerant salinity âTabatâ during boot stage plant.

Soil salinity is the major abiotic stress in plant agriculture strongly influencing productivity worldwide and it delimit the crop yield. Several abiotic stresses are united by the fact that at least part of their detrimental effect on plant performance is caused by disruption of plant water status. This can occur through decreased availability of water in the environment during drought, altere...
