Abstract: A field experiment was conducted during March 2012 to validate the balanced fertilization package to attain a factory average sugarcane yield of 150 t ha-1 from the present average of 95 t ha-1 at M/S. Rajshree Sugars and Chemicals Ltd. (RSCL) farm. The properties of experimental soil were neutral in pH, non-saline, low in organic carbon and available nitrogen, while high in available phosphorus and potassium status. The DTPA extractable Fe, Mn and Cu were sufficient while Zn was deficient. The effect of balanced fertilization on yield attributes and cane yields were significant. Among the treatments, STCR based fertilizer application (T6) recorded more number of millable cane and it was on par with T9 (RSCL package). The STCR based fertilizer application also recorded highest cane yield and sugar yield of 122.9 and15.91 t ha-1, respectively. The leaf nitrogen, phosphorus, potassium and sulphur nutrients content at different growth stages viz., 90th, 150th, 210th and 270th days after planting and at harvest indicated that the nutrients content were declined with advancement of growth stages. Considering B:C ratio, among the treatments T9 and T10 (TNAU package) which was on par with increase the yield from 102 t ha-1 to 128 t ha-1 could be recommended. But a revised balanced fertilization package with N at 275 to 300 kg, 112.5 kg P2O5 and 150 kg K2O along with 50 kg FeSO4 ha-1 and 5 t ha-1 bio-compost or any other organic manure with recommended bio-fertilizers such as phosphate solubilizing bacteria and arbuscular mycorrhizae has to be test verified to maximize sugarcane productivity.
