Abstract:
The objective of this study was to select high performing sugarcane varieties under the
bioclimatic conditions of Cote d'Ivoire. Twelve varieties of sugarcane, including three controls,
were tested in randomized six-repetition complete block devices, under irrigation at the
beginning and end of the season, and also under severe rain conditions. Varieties were
characterized using 6 technological criteria and 7 agro-morphological criteria. The variety R579
with 115.2 tc/ha and 10.5 tse/ha was best than controls Nco376 (86.3 tc/ha and 8.0 tse/ha) and
Co449 (91.6 tc/ha and 8.3 tse/ha) in irrigated conditions at the beginning of the season. At the
end of the season, R579 (111.7 tc/ha and 10.7 tse/ha) is better than the controls Co449 (85.1
tc/ha and 8.2 tse/ha) and Co957 (95.6 tc/ha and 8.8 tse/ha). Under strict rainfall conditions, R579
(79.6 tc/ha and 9.5 tse/ha outperforms controls NCo376 (72.3 tc/ha and 8.0 tse/ha) and Co957
(70.6 tc/ha and 8, 3 tse/ha). These results show that the R579 variety can be developed both in
village plantations under strict rainfall conditions and in irrigated farms at the beginning and end
of the season. |
