Longitudinal distribution of corn seeds depending on horizontal disk with different technologies

Resumen

The seed dosing mechanisms play a fundamental role in sowing operation. because the uniformity longitudi­nal distribution of seeds is one of the features that contribute most to proper the stand and to crop productiv­ity. Thus, the aim of this work was to evaluate the accuracy and longitudinal distribution of seeds utilizing conventional horizontal disc dosimeter and and to horizontal the disc dosimeter RampFlow. The experiment was conducted at the Laboratory of plantability FCA / UNESP, Botucatu-SP, and plantability mat was used for the distribution of seeds. The treatments were: conventional horizontal disc dosimeter and and to hori­zontal the disc dosimeter RampFlow., both of 11.5 mm diameter of the alveoli. The results indicate that RampFlow disc has precision similar to conventional disc, however, not been verified better efficacy for Reduction of failures and with of acceptable increased technology.
