摘要：A field experiment was conducted at Regional Sugarcane and Rice Research Station, Rudrur, during 2018-19 to study the effect of plant density and nitrogen management for realizing higher cane yield under bud chip method of planting in sugarcane (Saccharum officinerum). The treatments were plant geometry and nitrogen doses with three and four splits of application in split plot design. The recommended dose of nitrogen was 250 kg N ha-1. Among the geometry, 150 x 60 cm spacing recorded significantly higher cane length which was statistically at par with 150 x 30 cm. 150% RDN (375 kg N ha-1) with four splits of application recorded significantly higher cane length. Among the split application of nitrogen, four splits with 150% RDN at basal, 60, 90 and 120 DAP recorded significantly higher number of tiller at 90 and 120 DAP. Significantly higher single cane weight was recorded in 150% RDN with four splits of application in 150 x 60 cm. Significantly higher cane yield was recorded in 150% RDN with four splits of application in 150 x 60 cm spacing and was statistically at par with 150 x 30 cm spacing. This was followed by 100% RDN with four splits of application in 150 x 60 cm spacing.
