Description A field experiment was conducted at Agricultural Research Station, Sankeshwar,
University of Agricultural Sciences, Dharwad on medium black soil to study the effect of
sugarcane genotypes and different flooding duration on growth and yield of sugarcane under
simulated condition during kharif 2007. There were 8 treatment combinations consisting of
two sugarcane genotypes viz., Co 94102 and Co 86032 and four flooding durations at 7, 14
and 21 days with one control (non-flooded) treatments were laid out in RCBD in three
replications.
There was no significant difference in cane yield and quality parameters of sugarcane
genotypes due to various flooding durations. Both the genotypes are found to be susceptible
to the flood. This was indicated by reduced number of millable canes. Significantly higher
cane yield and better quality parameters are recorded in control treatment and were on par
with 7 days flood treatment. The cane yield and quality parameters are found to decrease, as
the flood duration increase from 7 to 21 days. Physico-chemical properties were significantly
deteriorated in all flooding duration compared to control. Nutrient status of the soil viz.,
nitrogen, phosphorus, potassium and calcium carbonate also significantly reduced in all
flooding durations. Bacterial, fungal, actinomycetes population significantly reduced in 21
days flooding duration compared to 7 and 14 days flooding duration.
