yieldThe growth dynamics of the crop were divided into two differ-ent stages: vegetative and bulb forming. Crop growth dynamics wasassessed on three plots (one plot = one replicate) corresponding toeach treatment. Every 15 days, 5 plants per treatment were ran-domly selected for measuring different variables (a procedure thatdestroyed the sampled plants); this was performed over a period of70 days post-transplantation and therefore involved 75 plants. Dryweights (after drying in ventilated oven at 80◦C for 72 h) of roots,leaves, and bulbs were determined for growth analyses. The relativegrowth rates (RGR, g/g/day) of roots, leaves, and bulbs were deter-mined as slopes of the natural logarithms of dry weights versustime between the individual sampling dates
