Yield and economics of spring planted sugarcane (Saccharum officinarum) under different planting method and nitrogen level

A field experiment was conducted at Regional Research Station, Karnal, CCS Haryana Agricultural University during spring 2017 to study on effect of planting methods and nitrogen levels on cane yield and economics of sugarcane. The experiment was conducted in split plot design with three replications. The treatments comprises of four methods of planting viz. conventional planting at 75 cm (M1), Half ridge open furrow irrigation planting at 75 cm (M2), Wide bed and furrow paired row planting (M3) and Wider planting (M4) at 120 cm and six different nitrogen levels viz. control (N1), 75 (N2), 100 (N3), 125 (N4), 150 (N5), 175 kg N ha (N6). The results of finding reveals that planting the sugarcane with wide bed and furrow paired row planting significantly increased number of millable cane, cane length, single cane weight, cane yield over conventional planting. Significantly highest cane yield (93.6 t/ha) was recorded in wide bed and furrow paired row planting followed by wider planting (86.7 t/ha) and half ridge open furrow irrigation planting (86.1 t/ha) over conventional methods (76.0 t/ha) with higher increment of 23.2% in M3, 14.1% in M4 and 13.3% in M2 than M1 method, respectively was obtained. Moreover, the crop fertilized with 175 kg N ha recorded significantly higher number of millable cane as compared to lower dose of nitrogen 0, 75, 100, 125 kg N habut did not differ significantly with 150 kg N ha.The net return in wide bed and furrow paired row planting, wider planting, half ridge open furrow irrigation planting and conventional planting was Rs. 184039, Rs.164056, Rs.159692 ha and Rs.128035 ha, respectively. Simultaneously, B:C was higher in wide bed and furrow paired row planting (2.53), wider planting (2.40) and half ridge open furrow irrigation planting (2.33) than in conventional planting (2.07).
