Maximum soil pH of 4.38 was obtained at 3 months after the application of lime. Different varieties of cabbage matures at different time irrespective of liming levels. Highest yield was obtained from treatments with the highest lime application. At 2.5 m tons lime per hectare only 50% of the cabbage heads were properly formed. The liming level should not be less than 7.5 m tons per hectare in order to get a profitable yield. The optimum level obtained from differentiation of the regression equation was at 11.5 m tons per hectare. The best lowland cabbage varieties were K.K. Cross and U.S. Hybrid. The N, P, K and Ca contents of the leaf responded either linearly or quadratically to the different levels of lime
