Field experiments were conducted at Agricultural Research Station, Kovilpatti between February 2012 to March 2014 to evaluate the influence of sowing windows and fertilizer management practices on growth and yield of rainfed sorghum. The treatment consisted of four date of sowing (D1: 39 standard week, D2: 40th standard week, D3: 41st standard week and D4: 42nd standard week in main plots and six INM practices (S1: Control (no manure, fertilizers and Biofertilizers), S2: 100 % RDF (40: 20: 0 kg NPK /ha) + enriched FYM 750 kg/ha, S3: 75 % RDF + enriched FYM 750 kg/ha, S4: 75 % RDF + Biofertilizer + TNAU MN mixture 12.5 kg/ha as enriched FYM 750 kg/ha, S5: 50 % RDF + enriched FYM 750 kg/ha and S6: 50 % RDF + Biofertilizer + TNAU MN mixture 12.5 kg/ha as enriched FYM 750 kg/ha) in subplots. The results revealed that 39th standard week sown crop registered higher ear head length, ear head girth, grains per ear head, grain yield and stover yield of sorghum but was comparable with 40th standard week and 41st standard week sown crops. These treatments were significantly superior to crop sown during 42nd standard week. Among the INM practices, 75 % RDF + biofertilizer + TNAU MN mixture 12.5 kg/ha as enriched FYM 750 kg/ha gave higher ear head length, ear head girth, grains per ear head, grain yield and stover yield which was comparable with 100 % RDF (40: 20: 0 kg NPK /ha) + enriched FYM 750 kg/ha. Lower values of yield attributes and yield were obtained with control treatment (No manures, fertilizers and micronutrients application).
