Field experiment was conducted to study influence of row spacing and plant density on
growth and yield of sugarcane under dual row planting in plant ratoon system at Regional
Agricultural Research Station, Anakapalle, during the year 2023-24. The experimental soil was
sandy loam in texture. Row spacings of 150 cm, 165 cm and 180 cm were tried with sett and
seedling planting under three different plant densities of 100 %, 125% and 150%. Studies on
plant crop of sugarcane revealed that sugarcane yield under dual row planting of 150 cm (79.2 t
ha-1) and 165 cm (77.8 t ha-1) were found to be statistically similar but significantly higher over
180 cm row spacing (71.9 t ha-1).Higher cane yield of 78.2 t ha-1 recorded with seedling planting
which was found on par with sett planting (74.3 t ha-1). There is no significant difference in yield
with respect to plant densities of 100 % (75.6 t ha-1) 125% (76.5 t ha-1) and 150 % (76.7 t ha-1). In
ratoon crop indicated that dual row planting of 150 cm and 165 cm gave statistically on par cane
yield of 67.2 t ha-1 and 64.8 t ha-1 respectively and significantly superior over cane yield at 180
cm row spacing (62.8 t ha-1). Cane yield was not influenced either due to type of planting material
or plant densities in ratoon crop of sugarcane.
