Effects of drought and salinity on maize phenology, morphology and productivity in a semi-arid environment

in rainfall patterns and temperature dynamics can seriously affect field crops and compromise productivity, due to increased drought and salinisation of agricultural land (Sarr et al., 2011). According to scenarios for climate change (IPCC, 2007), all these perturbations are predicted to become more accentuated in semi-arid areas, where competition for water resources for other human activities is also expected.
