Rice is the most important cereal crop; provide 40% daily calories for half of the world population. To ensure food security in near future, productivity must be increased double to maintain balance between population growth and food security. Unfortunately, rice production is not further increasing due to facing problem of various abiotic stresses in field. Multiple stress drastically affect on the plant photosynthesis, mineral nutrition, water relation, growth and development and major cause for reduction in production and productivity in major crop including rice. However, Plant adopts various mechanism or strategy to cope these unfavorable situations but there were yield penalty always associated with these stresses. To maintain yield stability under unfavorable situations plant physiologist and breeder start selection and improvement of physiological, morphological genetical trait. Effects of various abiotic stresses are complex in nature to sustain yield stability selection and improvement in complex trait can achieve the food security in near future. Therefore, consideration of all these in this review we summarized the effect of abiotic stresses and their tolerance mechanism in rice.

Key words: Multiple abiotic stresses, yield penalty, Physiological trait, Food security.
