dc.description.abstract | Certain sugarcane cultivars have been shown to exhibit resistance against
some parasitic nematode species. A field study was conducted to assess
potential of integrating this property into nematode control packages to
enhance sugarcane productivity. Three sugarcane cultivars were evaluated
in a split-plot design under three rates of nematicide aldicarb and replicated
thrice. Significant differences (P ≤ 0.05; P ≤ 0.01) were observed in girth,
plant height, millable stalks number and yield among the different cultivars
and nematicide rates. KEN83-737, N14 and Co 421 reduced nematode
populations in treated plots by 67, 49 and 32% while supporting nematode
population growth in untreated plots by 24, 33 and 92% respectively at 9
months after planting. Reduction in nematode numbers resulted in a mean
increase in yield, girth, plant height, millable stalks number and pol % cane
by 34, 18, 37, 53 and 6% respectively. This reduction was highest for
resistant and lowest for susceptible cultivars, hence indicating the reduction
was partly due to host-plant resistance status of the cultivars. This study
established that use of resistant/ tolerant cultivars with aldicarb has an
additive effect in reducing nematode numbers resulting in improvement of
yield and quality of sugarcane. | en_US |
