The soil and tissue nutrient survey was carried out in 12 blocks representing all the major sugarcane growing soils of the Nizamabad and Kamareddy Districts. As per the critical levels suggested for sugarcane, nearly 80.3, 9.45, 10.02, 25.9, 18.9 and 62.2 per cent of the plant tissue samples are deficient in N, P, K, Cu, Fe and Zn, respectively. Adequate amounts of Mn was noticed in all the sugarcane plant tissues. The data regarding fertility parameters of the sugarcane growing soils nearly 47.24, 91.33, 13.38 and 34.64 per cent of soils are deficient in organic carbon, N, P₂O₅ and Zn respectively. Adequate amounts of K, Cu, Fe and Mn was noticed in all the sugarcane growing soils. Results on nutrient content of soils and plants, it can be confirmed that the nitrogen deficiency in plants is a reflection of its deficiency in soils. But even though, there is no deficiency of potassium in soils its deficiency in plants is up to 10 per cent. Phosphorus is high in soils and the same is also reflected in plants. Regarding micronutrients, the deficiencies of Zn in soils is also reflected in plants also. But copper deficiency was observed in plants, in spite of the soils were sufficient.
