Salinity and crop productivity

Salinity has been reported as one of the major environmental factors playing a key role in soil degradation. Studies from various parts of the world indicated that the process of degradation is related to the dynamics of ground water, which is dependent on soil type, cropping systems and the condition of irrigation networks. Presently, research focus on crop productivity is propelled towards providing for today and future generations. Hence, the need to preserve arable land for agriculture becomes imperative. To this end, this paper reviews the effect of salinity on germination, seedling emergence; crop growth and crop yield. The paper also reviews the relationship between soil salinity and crop breeding.
