NUTRIENT STATUS AND EXTENT OF THEIR DEFICIENCIES IN MAIZE acceptable ranges as reported earlier by Escano et al. (1981). Iron (Fe) Leaf iron content in maize growing areas of three districts under study ranged from 14 to 250 mg kg –1 with a mean of 102 mg kg –1 . Out of leaf samples collected from 150 locations, the leaf samples in only one location was below the critical level 21 mg kg –1 as suggested by Jones (1990). In Nizamabad district the leaf Fe content ranged from 14 to 250 mg kg –1 with a mean of 98 mg kg –1 , recording highest mean Fe content of 168 mg kg –1 in Armoor mandal and lowest (66 mg kg –1 ) in Edapally mandal . The leaf Fe content in Karimnagar district ranged from 30 to 172 mg kg –1 with a mean of 95 mg kg –1 , having lowest mean Fe content of 56 mg kg –1 in Korutla mandal and highest in Dharmapuri mandal (149 mg kg –1 ). In Warangal district Fe content ranged from 39 to 200 mg kg –1 , with a mean Fe content of 113 mg kg –1 , having highest mean Fe content of 172 mg kg – 1 in Raghunathpally mandal and lowest (50 mg kg –1 )in Duggondi mandal. The reported values are within the acceptable ranges as reported earlier by Escano et al. (1981) and mean values are higher than as reported by Elwali and Gascho (1988), and Melsted et al. (1969). No mandal was noticed deficient in mean Fe content below the critical level out of total 30 mandals in three districts under study. Manganese (Mn) Leaf Mn content in maize growing areas of three districts under study ranged from 15 to 205 mg kg –1 with a mean of 130 mg kg – 1. Out of leaf samples collected from 150 locations, the leaf samples in one location was below the critical level of 20 mg kg –1 as suggested by Jones (1990). The leaf Mn content ranged from 30 to 205 mg kg –1 with a mean value of 135 mg kg –1 in Nizamabad district, recording lowest mean Mn content in Yellareddy mandal (62 mg kg –1 ) and highest in Balkonda mandal (161 mg kg –1 ). In Karimnagar district, the Mn content ranged from 110 to 186 mg kg –1 with a mean value of 149 mg kg –1 , recording highest mean value of 159 mg kg –1 in Jagitial mandal and lowest in Sarangapur mandal (135 mg kg –1 ). In Warangal district, the Mn content ranged from 15 to 189 mg kg –1 with a mean of 106 mg kg –1 . The lowest mean Mn content (38 mg kg –1 ) was noticed in Shayampeta mandal and higher content (149 mg kg –1 ) was recorded in Parvatagiri mandal. No mandal was deficient in mean Mn content out of total 30 mandals in three districts under study. The reported values are within the acceptable ranges as reported earlier by Escano et al. (1981) and are higher than values as reported by Elwali and Gascho (1988) and Melsted et al. (1969). REFERENCES: AOAC, 1980. Association of Official Agricultural Chemistry.
