Physiological variations of Peanut under salt stress

The Cultivated Peanut or Ground nut(Arachis hypogaea L.) is grown throughout the tropics.Being an important oil and food crop, the present day production and productivity needs to be enhanced to meet the demands.But in the arid and semiarid regions, the Groundnut farmers are witnessing the adverse yield reduction due to biotic factors and abiotic constraints such as Salinity and Drought.Moreover the declining natural resources and distancing of technology gap also leads to a complex situation of rural disenchantment.In order to increase the yield parameters, a better understanding of the plant physiological mechanisms to salinity/ sodicity stress is needed.The development of amelioration technology may pave the way for improving growth and yield of peanut crop growing under hostile conditions.Thus crop Physiologists can play a pivotal role in reaching the potential yield of peanut crop.
