Abstract: 

Irrigation is a major factor in sugarcane growing. Unquestionably,
sugarcane is one of the most Water - demanding crops after rice. The
amount of water recorded from rainfall or irrigation systems in a given field
are always considered as uniform despite of heterogeneous condition within
the field. The application of water in the soil is one but the uptake by plant
is the most side of consign. Water uptake by plant which is among of the
root function, is mainly influenced by infiltration rate. Other side of these is
right to say, any hindrance factor to infiltration rate and its capacity is
primary killer for plant growth. Soil compaction is one of greatest factor
which hinder water percolation into the ground as it deform soil structure.
In infiltration test conducted at 6P4D shows the statistical difference
between infiltration rate in compacted and non-compacted portions. The
highest and lowest infiltration rate recorded was 383mm/hour to
116mm/hour and 220mm/hour to 35mm/hour in non-compacted and
compacted portions respectively. Once the data were subjected to ANOVA
using GenStat software was found to be statistically difference at 5% level
of confidence. Being in a side of quantifying its consequences will help to
make friendly decision in our farming system and irrigation scheduling in
order to avoid water loss through runoff and flooding as a result of poor
infiltration. The main purpose of this writings is to examine quantitatively
on how compaction influence infiltration rate and come-up with
recommendation such as Controlled Traffic system.
