In Pakistan, about 70% people directly and indirectly depend on Agriculture for their lives. Agriculture provides 25% GDP of Pakistan have severely been affected by alkalinity and salinity. Effect of different pH on seed germination of three major crops (Wheat, Rice and Gram)varieties were studied. It was observed that Local White variety of wheat crop was more resistant to a wide rage of pH as compared to other two varities showed more tolerance than other crops (Wheat and Gram ) against high pH. It has also been observed that Local variety in Gram crop showed more seed germination than other two varities. The pH range for optimal seed germination in Gram crop shoed more seed germination than other two varities. The pH range for optimal seed germination in Gram crop was 7.5 to 8.5.
