Abstract:
Sugarcane production was affected by numerous factors, which subsequently reduce cane and
sugar yield. Among those constraints, planting geometry is the most important one. To solve
the problem, regarding intra-row setts spacing, research findings should be taken. However,
research outputs concerning this aspect are not available at Tana Beles Sugar Estate. The
experiment was conducted using randomized complete block design within a factorial
arrangement; three sugarcane varieties (N14, NCo334, and C86/56) and four intra-row setts
spacing (5 cm overlap, end to end, 5cm, and 10cm space between setts) replicated three times
in each block at Tana Beles Sugar Estate (Jawi) from March 05,2022 –June 27,2023. All data
were collected as per the plan. The analysis of variance was performed by SAS 9.4 and means
were compared by Least Significance Difference (LSD) t Test at 5% level of probability for
interpretation of results. Analysis of variance revealed that variety was a significantly
(P<0.001) influenced the sprout percentage, tillering, stalk height, stalk diameter, numbers of
mille able cane, cane yield, sugar yield, percent pole and recoverable sugar and also
significant influenced (P<0.01) on percent brix. The study also revealed that the setts spacing
was a significant (P<0.05) difference on apparent purity and spacing also significant
(P<0.01) influenced on stalk diameter, numbers of mallable cane, estimated recoverable
sucrose and pole percent. It was also showed significant (P< 0.001) difference in, sprout
percentage, cane weight, cane yield and sugar yield. The interaction between varieties and
setts spacing for most parameters were showed significantly difference except stalk height,
percent pole and recoverable sucrose. Finally, there were significant(P<0.05) difference
among the setts spacing’s used in cane yield and sugar yield, the highest cane yield and sugar
yield was obtained from N14 variety 5 cm overlapping at Tana Beles. In this study showed
that variety N14 on 5cm overlapping intra-row sett spacing would recommended on Tana
Beles Sugar Estate
