Yield and Quality of Ratoon Sugarcane Are Improved by Applying Potassium under Irrigation to Potassium Deficient Soils

The current study was carried out at the experimental farm of Rana Sugars Ltd., Buttar Seviyan, Amritsar, Punjab, India, to identify methods improve yield and quality ratoon sugarcane in potassium-deficient soils. treatments comprised two levels irrigation, resulting plants which either received sufficient water (I1) or were water-stressed (I2), four rates potassium (K) application: 0 (K1), 40 (K2), 80 (K3) 120 (K4) kg K2O ha?1. results showed that irrigation did not influence crop parameters significantly, although all presented higher values for I1-treated plots. Compared K1 (i.e., ha?1 K fertiliser applied) treatment, K2, K3 K4 yielded 11.16, 37.9 40.7%, respectively, millable canes 1.25, 5.62 13.13% more nodes per plant, respectively. At 280 days after harvest first (plant) crop, I1 treatment provided ratoons up 15.58% than those obtained with I2 cane girths 7.69% wider yields 7.29% observed treatment. While number plant differ significantly between treatments, there significant differences other parameters. Quality (with exception extraction percentage) enhanced by benefit-to-cost ratio (B/C) I2, due a reduced productivity associated both levels, resulted highest K1-, K2- K4-treated plots instances insect infestations receiving Relative plots, infestation early shoot borer (Chilo infuscatellus) 18.2, 6.0 12.2% higher, underwent K1, K2 while top (Scirpophaga excerptalis) 21.2, 9.21 14.0% stalk auricilius) 10.7, 8.10% higher.
