Abstract Two pot culture experiments were conducted to study the effect of sub-surface placement of chlorosis resistant clay loam soil to the plants on periodical chlorophyll concentration, leaf composition and root growth of chlorosis susceptible (CO-7219) variety of sugarcane grown in chlorosis prone sandy clay loam soil under greenhouse conditions. Normally clay loam soil with Vertic properties would not induce symptoms of chlorosis in sugarcane. But the beneficial effect of such resistant soil was not observed at all in all the plants of the first experiment, suggesting that such a placement in the potted soil was not enough for interception of plant roots and thereby to alleviate the chlorotic conditions of the potted plants. But there was a strong positive correlation between leaf chlorophyll concentration and root growth of sugarcane. Similar relationship was found with dry matter of plants tops both at the 126th and 134th day of plant growth. The higher root growth probably met the iron requirement for chlorophyll synthesis in sugarcane. The limitations of the first experiment was over come by placing one kilogram of chlorosis resistant soil right at the bottom of the potted soil. The placement, of the chlorosis resistant soil at the bottom of the pots favoured maximum root interception and recovered the chlorotic conditions of the ploted plants. Chlorosis resistant soil could supply enough plant available iron for synthesis of chlorophyll in sugarcane leaves, but the placement of soil ten centimeter below soil surface was the below soil surface was not enough to correct the chlorotic conditions of the plants.
