Abstract:
Ploughsole method along with vermicompost recorded significantly higher cane yield in plant and ratoon crop (113.06 and 99.75 t ha-1respectively), available nitrogen (318.11 and 297.42 kg ha-1 respectively), phosphorus (36.79 and 32.72 kg ha-1 respectively) and fertilizer use efficiency (307.4 and 240.1 kg cane kg-1 NPK applied 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), available nitrogen (284.67 and 266.31 kg ha-1 respectively), phosphorus (31.92 and 27.59 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), available nitrogen (275.07 and 255.68 kg ha-1 respectively), phosphorus (30.21 and 25.86 kg ha-1 respectively) and fertilizer use efficiency (295.8 and 230.1 kg cane kg-1 NPK applied respectively) than100 % 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), available nitrogen (331.33 and 312.67 kg ha-1 respectively), phosphorus (38.81 and 34.71 kg ha-1 respectively).
