A field experiment was conducted during 2014-15 to study the impact of continuous application of organic manures and inorganic fertilizers on cane yield, jaggery yield, quality of sugarcane and soil fertility status after harvest at Agricultural Research Station, Perumallapalle, ANGRAU. The experiment consisted of two treatments i.e. organic and inorganic treatments. FYM and vermi compost were applied to organic treated plot based on N equivalent and recommended dose of fertilizers (224:112:112 kg NPK ha-1) were applied to inorganic treated plot. Yield and juice quality parameters were recorded at harvest. Soil samples were collected to determine available nutrient status at harvest. Results revealed that cane yield, cane length, Commercial Cane Sugar (CCS) % and CCS yield were significantly affected by organic manures and inorganic fertilizers. The inorganic treated plot recorded higher cane yield (97.4 t ha-1), cane length (264 cm), CCS% (12.37%) and CCS yield (11.03 t ha-1) compared with organic treated plot (92.6 t ha-1 of cane yield, 251 cm of cane length, 12.10% of CCS and 10.09 t ha-1 of CCS yield). However Sucrose (16.17%) was higher with application of organic manures than inorganic treated plot (15.92%). Higher jaggery yield (11.05 t ha-1) was recorded with inorganic treated plot than organic plot (10.09 t ha-1). Regarding soil properties available nitrogen and potassium were significantly higher with organic treated plot (244 and 265 kg ha-1 of available nitrogen and potassium respectively) than inorganic plot (239 and 258 kg ha-1 of available nitrogen and potassium respectively).
