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

Abstract

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.
