a paper-pot transplanter was designed, developed and evaluated in the field by transplanting sugar beet seedlings grown in paper pots. a ground-driven counter wheel equipped with an infra-red sensor measures the traveled distance and sends the corresponding signals to a micro-controller. a step motor controlled by the micro-controller turns the driving shaft of the paper-pot metering mechanism ...

Precision planters are recently being adopted for seeding canola to improve crop establishment and seed yield. This study determined the effect of using precision (30.5 50.8 cm row width) conventional air drill seeders at different rates (20, 40, 60, 80, 160 seeds m −2 ) on plant density The was conducted 4 yr (2016 2019) three locations in southern Alberta. Plant increased with higher followin...
