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