Abstract
Field experiments were carried out at the Regional Agricultural Research Station (RARS), Anakapalle, Andhra Pradesh, India, for 14 continuous years from 2011 to January 2025 to assess the yield, juice quality, soil properties and cost economics of sugarcane under organic vis-à-vis conventional farming systems. Organic farming recorded a higher number of millablecanes (75,142canesha-1), cane yield (72.38 t ha-1) and sugar yield (9.64 t ha-1) compared to conventional farming (73,202 ha-1, 71.68 t ha-1 and 9.27 t ha-1, respectively). Juice quality parameters including sucrose (18.75%), commercial cane sugar (13.05%) and purity (90.19%) were superior in organic management compared to conventional practices (18.29%, 12.71% and 88.48%, respectively). Soil organic carbon, available nitrogen and phosphorus showed slight improvement under organic farming, while potassium status was higher in conventional system. Cost of cultivation was slightly lower under organic management, resulting in a comparable B:C ratio (0.88 Vs 0.86). In conclusion, results suggest that organic farming in sugarcane can maintain yield levels while enhancing soil quality and juice quality parameters, with potential for long-term sustainability.
