Abstract

                                Application of P in the form of Mussooriephos recorded higher Brix, Sucrose, Purity, Cane yield and Commercial cane sugar per cent (CCS %) than P in the form of DAP for sugarcane. NPK + Pyrite 100 kg (P as Mussooriephos) recorded significantly higher CCS %, brix, sucrose and purity. The highest cane yield (103.5 t/ha) was obtained with NPK (Mussooriephos)+ Pyrite at 300 kg/ha. Foliar application of FeSO4 was better than soil application of FeSO4 for all the above quality parameters. Pyrite upto 300 kg/ha with FYM at 10 t/ha and P as Mussooriephos recorded higher available micronutrients especially iron.
