Effect of irrigation and potash levels on growth, yield and quality of spring sugarcane (Saccharum officinarum)

I1 plots had higher germination (5.61%), millable canes (9.09%), brix (5.19%), yield (0.6%) and CCS (t/ha) (2.35 4.37% at 10th 12th months), respectively. K3 reported significantly performance as compared to K1 K2 treatments while being par with the K4 treatment. Benefits were be highest treatment under water stressed conditions. Hence, 80 kg K2O/ha potash deficient soils prove a better option for cane growth, quality parameters.
