Agro-physiological traits in soybean (Glycine max L.) during salinity

Plant performance and productivity is influenced by epigenetic variables, i.e. salinity, drought, heat, cold and flooding characteristics etc. of any agro-climatic zone. The economic development of any nation gets co-related with the suitability of available natural variables. The world agriculture is passing through a lot of challenges for planning to produce nearly 70% more food for an additional 2.3 billion people by 2050 (FAO,2009; Hasanuzzaman et al.,2013). The in-vivo quality control of photosynthetic apparatus may induce attributes for improving crop productivity (Singh et al., 2008). As, the major abiotic stresses such as salinity, drought, heat, cold and flooding etc. negatively influence plant growth, biomass production and yield of staple food crops up to 70% which threatens the food security worldwide. More than 45 mha irrigated land which accounts to 20% of the total land found to be affected by the salinity, and 1.5 mha becomes out of production each year due to high level of salinity (Munns and Tester 2008)across the globe. Soybean (Glycine max L.) is a species of legume native to Eastern Asia. An attempt has been made to revel influence of salinity on soybean.
