Abstract
Abstract. A commercial, manually fed vegetable transplanter was modified and adapted to work in no-till soils. Details of the modifications are described in this article. The aim of this research was to evaluate the performance of this transplanter under actual field conditions in both tilled and no-till soils. The draft force in the no-till soil was measured for different working tools mounted for tilling or loosening a narrow band of soil before passing with the furrower. The combination of a ripper shank opener with a straight nose point resulted in the lowest draft force values per unit of working depth. The transplanter accuracy and transplant success rate were evaluated in different vegetable crops. The accuracy parameters (multiple index, miss index, quality of feed index, and precision) were estimated and in general were similar in the tilled and no-till soils, indicating that the transplanter was able to operate in both soil conditions with the same accuracy. The transplant success rates were also similar in both soil conditions. The transplanter thus offers a satisfactory technical solution for transplanting vegetables in both tilled and no-till soils. Keywords: Conservation tillage, draft force, organic farming, transplanter accuracy, transplant success rate.
