Desenvolvimento de semeadora para plantio direto de experimentos : protótipo-III.

Abstract

This study aimed at developing a prototype of a no-till seeder for agricultural experiments involving research activities related to soil fertility of annual crops under no-till. The seeder is equipped with a variable number of metering devices for seeds, andsolid fertilizers, as well as furrow openers, which facilitate the study of different combinations between seeds, fertilizers, and limestone. The prototype performed outstandingly in preliminary field trials.
