Maize

Rainfed Maize Field Preparation To break hard pan in rainfed alfisols, chisel ploughing once in three years. Plough the field with disc or mould board plough once followed by cross ploughing with cultivator. Apply 12.5 t/ha of FYM or compost with 10 packets of Azospirillum (2000 g/ha) before last ploughing. Form ridges and furrows using bund former or ridge plough with 6 m long and 45 cm apart. Application of Fertilizer Fertilizer dose (Rainfed Alfisols): 60:30:30 kg N: P₂O₅: K₂O/ha. Apply half of N (65 kg urea/ha), full dose of P₂O (188 kg SSP/ha) and K₂O (50 kg MoP/ha) basally with enriched FYM before sowing. Place remaining half dose of N (65 kg urea/ha) at tasseling stage. Fertilizer dose (Rainfed Vertisols): 40:20:0 kg N: P₂O₅: K₂O/ha. Apply half of N (43 kg urea/ha) and full dose of P₂O (125 kg SSP/ha) basally with enriched FYM before sowing. Place remaining half dose of N (43 kg urea/ha) at tasseling stage. Soil test crop response – IPNS based fertilizer recommendation for hybrid maize (Rainfed) ---(Please Click Here) Seeds and Sowing Seed Rate: 20 kg/ha for Maize hybrids COH(M) 6, COH(M) 8 and COH(M) 11 . Spacing: 45 cm X 20 cm Intercropping Maize + cowpea/maize + blackgram is suitable for red lateritic soils of Southern districts. Vertisols (Black soil) of Southern district, maize + redgram intercropping systems is ideal. Weed management Application of atrazine @ 0.50 to 0.75 kg/ha as pre emergence on 3 DAS using Backpack/ Knapsack/ Rocker sprayer fitted with a flat fan nozzle using 500 litres of water/ha followed by one hand weeding on 30-35 DAS. Foliar nutrition: Foliar spray of TNAU Maize Maxim @ 3 kg/acre in 200 litres of water at tassel initiation and at grain filling stages improves grain filling, grain yield and drought tolerance. Water Stress: Foliar spray @ 500 ml/ha of PPFM (Pink Pigmented Facultative Methylotroph) during the critical stages of crop growth for mitigation of drought. Updated on May 2023
