2. Why mechanized transplanting??
โข To benefit from the potential of younger seedlings.
โข To utilize available space (wider space healthier crop higher yield).
โข To maximize nutrient use efficiency (by mechanical weeding).
โข To produce more crop per drop (increase water use efficiency).
โข To sustain soil quality and fertility for more sustainable production
