Abstract
The present work was conducted at Shandaweel Agricultural
Research Station, Sohag Governorate during 2009/2010 (plant cane)
and 2010/2011 (first ratoon) to investigate the effect of three row
spacing (80, 100 and 120 cm), three nitrogen levels (170, 200 and 230
kg N/fed in plant cane and 185, 215 and 245 kg N/fed in the 1st ratoon)
on yield and quality of two sugarcane varieties viz. G.99-160 and
G.T.54-9 (the commercial variety) in a split-split plot design with three
replications.
The results showed that planting sugarcane varieties in rows
spaced at 80-cm apart attained a significant increases in cane stalk
height, number of millable canes, cane yield/fed, brix, sucrose,
sugar recovery percentages and sugar yield/fed compared with
those planted at 100 and 120 cm. Significant increase in stalk
diameter was recorded at 120 cm row spacing.
The results indicated that the two sugarcane varieties differed
significantly in cane stalk height, stalk diameter, number of
millable canes, cane and sugar yields, whether they were grown as
plant cane or 1st ratoon crop, as well as brix, sucrose percentages in
the 1st ratoon. Insignificant variance was detected between the
tested varieties in sugar recovery %, in the plant and 1st ratoon
crops.
Raising N fertilization level from 170 to 200 kg N/fed for the
plant cane and from 185 to 215 kg N/fed for the 1st ratoon crop < br />resulted in a significant increase in cane stalk height, stalk
diameter, number of millable canes, cane and sugar yields /fed.
Under conditions of the present work, growing G.T.54-9 and/or
G.99-160 sugarcane varieties in rows of 80-cm apart and fertilized
with 200 and 215 kg N/fed for the plant cane or 1st ratoon,
respectively, can be recommended to get the maximum cane and
sugar yields/fed.
