Effect of Plant Density and Nitrogen Management for Realizing Higher Cane Yield under Bud Chip Method of Planting in Sugarcane (Saccharum officinarum)

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.
