Resumo
Objetivou-se com este trabalho utilizar uma plantadora de batata para operar em solo cuja superfície não havia sido
revolvida (plantio direto) ou pouco revolvida (cultivo mínimo); avaliar o desempenho da cultura instalada por meio
de modificações da máquina e pelo plantio convencional. O experimento foi conduzido num delineamento em blocos
casualizados, com as parcelas subdivididas e quatro repetições. Pelos resultados obtidos, conclui-se que: a produção
de tubérculos comerciais não foi afetada pelos tratamentos e atingiu a média de 28.266 kg ha -1 ; sem amontoa o cultivo
mínimo propiciou maior número e massa de tubérculos não comerciais; e que a amontoa, operação considerada
imprescindível por alguns autores, se mostrou dispensável nas condições em que foi conduzido o experimento.
The objective of this study was to use a potato planter for operation in soils whose surface had not been plowed (no-tillage) or little plowed (minimum tillage), evaluating the performance of the installed culture by means of modifications to the machinery and conventional planting. An experiment was conducted in casual blocks was carried out with subdivided plots and four repetitions. The results showed that: the production of commercial tubers was not affected by the treatments and the average yield obtained was 28,266 kg ha -1 ; minimum tillage (MT) resulted in the greatest number and mass of non-commercial tubers; and tilling, an operation considered essential by some authors, showed to be dispensable for the conditions in which the experiment was performed.
