Saline conditions affect rice lands in coastal areas due to tidal intrusion of seawater, and also in inland areas where bedrock is rich with sodium salts or soluble salts accumulated through the river streams or canal. In addition to high salt content, rice suffers from imbalances in nutrients such as phosphorous (P) and zinc (Zn). Compounding problems like acidic soils, drought and submergence in some areas, create multiple problems for farmers seeking out a viable livelihood. Two promising lines of inquiry involve, first, the introduction of salt-tolerant genes into popularly grown varieties, and, second, the development of optimum nursery and natural resource management practices that make seedlings more robust to withstand these stresses |
