Various environmental stresses viz. extreme temperatures, problem soils including soil salinity, drought and flood have affected the production and cultivation of agricultural crops. Among these, problem soils (acidic, alkaline, sodic, and saline) is one of the most devastating environmental stresses, which causes major reductions in cultivated land area, crop productivity and quality caused by variable concentration of ions in the soil. Soil reaction (pH), in particular, is an important variable, perhaps due to its influence on many other soil properties and processes affecting plant growth. Many plant characteristics (i.e., traits) such as height, lateral spread, grains yield, biomass, flower size and number, pollen production, etc., are influenced by the pH of the soil . In this study, we investigated the effects of soil pH on the germination and growth (shoot and root height, yield, dry weight, etc.) of Triticum aestivum (bread wheat)  and Zea mays (corn) . Highly acidic soil (pH 4.0) was collected from a site (hot-spot) in Sonipat district of Haryana. Simultaneously, problem soils, both acidic and alkaline soils were prepared by fortifying garden soil (pH 7.0) with weak acidic and basic solutions using aluminium sulphate and calcium hydroxide, respectively. Experiments were conducted with replicates, to counter experimental errors. A set of control pots having seeds of wheat and maize grown in garden soil was also set up.
