Abstract:
In plant and ratoon crop ploughsole method along with vermicompost recorded significantly higher cane yield (113.06 and 99.75 t ha-1 respectively), organic carbon (0.43 and 0.41 %), nitrogen uptake (258.15 and 197.99 kg ha-1 respectively), phosphorus uptake (27.25 and 22.75.72 kg ha-1 respectively) and potassium uptake (216.69 and 180.48 kg ha-1 respectively) compared to farmers practice of surface broadcasting. Application of 100 % RDF higher cane yield in plant and ratoon crop (122.60 and 109.21 t ha-1 respectively), organic carbon (0.47 and 0.44 % respectively), nitrogen uptake (313.22 and 212.17 kg ha-1 respectively), phosphorus uptake (33.12 and 24.88 kg ha-1 respectively) and potassium uptake (284.93 and 214.15 kg ha-1 respectively) than applying 75 and 50 % RDF in plant and ratoon crop. Split application of potassium 50 % as basal and 50 % at earthing up recorded significantly higher cane yield (109.51 and 95.79 t ha-1 respectively), organic carbon (0.43 and 0.46 % respectively), nitrogen uptake (232.54 and 167.89 kg ha-1 respectively), phosphorus uptake (24.44 and 19.59 kg ha-1 respectively) and potassium uptake (207.32 and 165.73 kg ha-1 respectively) than entire potassium as basal. Among all treatment combinations, application of 100 % RDF along with vermicompost in plough sole method and potassium 50 % as basal and 50 % at earthing up recorded the higher cane yield (142.84 and 117.40 t ha-1 respectively), organic carbon (0.51 and 0.48 % respectively), nitrogen uptake (434.72 and 282.15 kg ha-1 respectively), phosphorus uptake (48.26 and 34.27 kg ha-1 respectively) and potassium uptake (382.20 and 272.09 kg ha-1 respectively).
