dc.description.abstract | An educational variable‐rate application (VRA) sprayer was developed and laboratory tested at the University
of Seville (Spain). It was designed and built during 2009 by the undergraduate engineering students in a Precision Agriculture
course and used as a teaching model in an Agricultural Machinery course during 2010. The first stage involved mounting
all the instrumentation, sensors, and the hydraulic system on a metal platform. The second stage involved mounting a DGPS
receiver, flowmeter, automated application control system, and all necessary electrical connections to the platform.
Preliminary calibration tests of the equipment at a constant speed of 0.375 m s‐1 (1.35 km h‐1) showed good performance for
pressure (kPa) and application rate (L ha‐1) (R2 = 0.998, p < 0.001). To evaluate the teaching method based on the prototype,
a short‐answer assessment test was conducted consisting of ten multiple‐choice questions, each with one possible correct
answer. Data were analyzed using analysis of variance (ANOVA). The factors were the teaching method (TM), repeated course
(R), and attended theory (AT). In addition, the effect of a covariate (number of times a student repeated the course) in the
factors was controlled with an analysis of covariance (ANCOVA). The effect of teaching method was significant for the score
on the VRA sprayer questions (SPS) variable and the score on the conventional sprayer questions (SCS) variable (p < 0.001
for both). The average success for students using the prototype sprayer was 86%, compared to 60% for those using a
conventional sprayer. The total cost of the VRA prototype sprayer was 40% less than the cost of retrofitting a conventional
sprayer with precision agriculture equipment. Since the students were engaged in their own learning, they maintained a high
level of enthusiasm throughout the course when utilizing the VRA prototype sprayer. It has proved to be a complementary and
beneficial alternative for improving the students' education in the Agricultural Machinery course. | es |
