In the following, you will find the different activities executed during the professional supervised
exercise (PSE) or internship for Agronomia Tropical from Centro Universitario de Sur Occidente
(CUNSUROC), the activities of the internship took place in the Tululá sugar mill, in the area of
Ingenieria Agricola.
The crop used for the activities of the internship was sugar cane (Saccharum officinarum), for
which the irrigation has always been an important need for the development of the crop, this is
why in Tululá sugar mill, there were two different testing areas (Finca El Minar and Finca
Santander) for the use of mini – sprinkler irrigation system. The general objective for this
document was: to evaluate the system of mini – sprinkler irrigation for sugarcane (Saccharum
officinarum) in Finca El Minar and Finca Santander of Tululá Sugar mill, in San Andres Villa
Seca, Retalhuleu. In order to reach the objective set there were two phases, a field area that is
where the tests were executed for the recollection of data, and the office phase which is where
all the data from the field was later analyzed to reach the conclusion about the mini – sprinkler
irrigation system.
The field activities realized are the following, basic infiltration test using the double cylinder
method in both test areas utilized for sugar cane. The results of those tests were later compared
with the set intensity utilized by the irrigation system to verify if the soil in the testing grounds had
the capacity of absorbing the amount of water being applied by the mini – sprinkler system.
Another test was also to set rain gauges in a squared pattern every three meters, with the
means to calculate the amount of water applied by the mini – sprinkler system used in the
testing areas, each test had a length of three hours nonstop. During those three hours, the
pressure of each sprinkler was determined. As a result in Finca El Minar the mini – sprinklers
have a pressure of 49 psi (3.45 kg/cm2) applying 1.27 m3/h (1270 l/h) meanwhile in Finca
Santander the results were 25 psi (1.76 kg/cm2) while applying 0.88 m3/h. These results were
analyzed and it was determined that in Finca El Minar the irrigation system was operating bellow
its capacity, in Finca Santander it was determined that the irrigation system was being operated
under inadequate conditions for the system.
Back at the office, the data recollected during all the different tests. It was determined that the
amount of water being applied in Finca El Minar should be of 41.0 mm, the amount of water
recollected by the rain gauges was an average of 59.4 mm. In Finca Santander, the amount of
4
water needed for the sugar cane is 47.92 mm, and the rain gauges only received 29.94 mm of
water. |
