INTRODUCTION
Soil Parameters
The global population is expected to increase to 9.7 billion in 2050 and there are concerns about the capacity
of agriculture to produce enough food for the growing population. By some estimates, food production will
need to go up by about 60 percent either through increase in crop yields per unit area or expansion in the
arable land by 2050 to meet the demand (World Population Prospects-the 2008 Revision, UN, 2009).
Furthermore, several regions already suffering from malnutrition, water scarcity and soil degradation have
been forecast to have a large population growth which raises serious concerns about whether traditional
agricultural methods and crops species will have the capacity to sustain global food production targets.
This experiment was conducted in Agricultural research center, California, USA. Salinity treatment began.
Salt treatment was given in 40 mM/day increments until the final concentration (400 mM) was reached.
Samples and measurements were taken 8 weeks after start of the treatment
MATERIALS AND METHODS
This experiment was conducted in Agricultural research center, California, USA. Salinity treatment began.
Salt treatment was given in 40 mM/day increments until the final concentration (400 mM) was reached.
Samples and measurements were taken 8 weeks after start of the treatment. Leaf imprints were taken from
abaxial leaf surface using nail polish. These imprints were later examined under a high magnification (200×)
microscope, and stomatal density (number of cells per surface area) was counted.
