At the Corn and Sorghum National Research Center in Sete Lagoas, Minas Gerais State, an evaluation was made of the performance of a low pressure central pivot equipped with drop sparay, operating at 100% of its displacement capacity. The tests carried out were the following: without drop spray; drop spray of 1.2m; 2.0m and 2.6m lenght. For each test, the uniformity coefficients of Christiansen (CUC) and distribution (CUD), the application efficiency, in potential (EPa), and the highest precipitation intensity were determined. It was concluded that: The lenght of drop spray did not affect distribution uniformity; The collected water plate at the end of the pivot line showed a large variation; Topographic characteristics influenced distribution uniformity; Drop spray increased application efficiency, in potential, reducing pressure at the diffusor exit. Proximity of the diffusor to the ground decreased the covering diameter and increase precipitation density. |
