Researchers studied how different combinations of nutrients affect the growth and yield of garlic. They tested ten nutrient combinations on garlic plants and found that using 125% of the recommended NPK + Zn dose resulted in the best outcomes. This led to taller plants, more leaves, heavier bulbs, larger bulb diameter, and higher yields per plot and per hectare. The cloves were also larger and there were more cloves per bulb when this nutrient combination was used.
