Abstract: Soil salinity and sodicity has become a severe threat to ensure food security in the developing world. Increasing salinity had significant impact on food production and more agricultural lands are expected to become salt affected due to climate change. Cereals contribute mainly to food production and growing grain crops on saline and sodic soils require adoption of different strategies for sustainable crop production. Based on the above view an experiment were undertaken at Anbil Dharmalingam Agricultural College and Research Institute, Navalurkuttapattu, Trichy to study the effect of seed priming on alleviating sodicity stress. The following two rice varieties TNAU Rice TRY 3 and I.W. Ponni seeds were primed with 1% KCl, 1% mixture of CaSO4+ZnSO4+FeSO4, GA3 20 ppm, +Azophos 1 % + Pseudomonas fluorescens 1.0 %, 1% mixture of KCl+ CaSO4+ZnSO4+FeSO4 +GA320 ppm +Azophos 1.0 % + Pseudomonas fluorescens 1.0 % individually as well as combinations followed by foliar spray of 0.5% ZnSO4, 2 % DAP and 2% cowpea pulse sprout extract at active tillering stage. Among the different combinations of priming tried, the seeds primed with 1% mixture of CaSO4 + ZnSO4 + FeSO4 + GA3 20 ppm + Azophos 1% followed by 0.5 % foliar spray of ZnSO4 at active tillering stage recorded the improved biochemical and physiological constituents such as proline content (744.5 µ g-1), soluble protein content (8.63 mg g-1).Nitrate reductase (21.3 µ moles NO-2 g-1 h-1)chlorophyll (1.800 mg g-1) and chlorophyll stability index (60.3).
