Solution
The correct option is C Salinity Salinity affects sprouting of seeds. Hence, during first irrigation, more quantity of water should be supplied to neutralize the effect of salts. Thereafter, even during subsequent irrigation, along with reducing the quantity of water, the duration between two irrigations should be reduced so that soil does not get dry and dissolution of salts continues in the humid soil.
