FIELD TEST OF TIPS AT DIFFERENT SPEEDS WITH HIGH PROPELLED SPRAYER.

Abstract

FIELD TEST OF TIPS AT DIFFERENT SPEEDS WITH HIGH PROPELLED SPRAYER. In the current conjuncture of modern and technified agriculture there is a growing concern about factors that may limit grain production per unit area and always seeking to exploit the maximum genetic potential of available cultivars. The technology of application with the choice of equipment, tips and spray nozzles has become an ally of the producer in the field. Which led us to the development of this work with the objective of testing 3 spray tips at 5 speeds in Morgan 580 off-season corn. The application occurred close to the corn tearing 80 days after planting, using a STARA Imperador sprayer set for a syrup distribution in the flow rate of 100 Liters per hectare. The experiment comes from a randomized block design with four replications with 3 sensitive roles distributed in the middle third of the plants totaling 16 sample units per treatment. , diameter and droplet area were thus six variables analyzed in total, the water-sensitive paper readings were taken through the R statistics program and the ANOVA was made and then following the Shapiro, Barlett tests and the appropriate test at 5% significance. Talk a little bit about the organization of the plots and the use of the sensitive paper, talk a little about what was evaluated, Number of drops, coverage area, the regression statistic in the R etc ... We conclude that the speed is a factor that decreases. efficiency very significantly, losing in pest and disease control efficiency and for coarse drop tips the best application range is at low speeds.
