Irrigation Regimes on Utilization of Nutrients, Yield and Quality of Sugarcane (Saccharum officinarum L.)

With a view to study the influence of irrigation regimes at critical stages of sugarcane an investigation was carried out at Agricultural Research Station, Tamil Nadu Agricultural University, Bhavanisagar, India during Mid-late season (March–April) using Co 6304 as test variety. Treatments consisted of eight irrigation regimes created by imposing two levels of irrigation 0.75 and 0.5 IW/CPE ratio at critical stages (tillering, grand growth and maturity). The results revealed that irrigating sugarcane at 0.75 IW/CPE ratio at tillering and growth and 0.5 IW/CPE at maturity phase recorded highest nutrient uptake, cane yield (139 t/ha) with 10.6 % CCS consuming 1791 mm of water the highest water use efficiency of 77.3 kg/ha mm.
