The effects of P rate (0, 25, 50, and
75 kg/ha as superphosphates) and application method (band and broadcast)
on the yield and quality of garlic were studied in Jordan during
1999/2000 and 2000/2001. P at 75 kg/ha resulted in the greatest plant
height at 120 days after planting (66.0 cm), bulb length (3.45 cm),
bulb diameter (3.55 cm), clove breadth (3.30 cm), clove length (3.55
cm), number of cloves per bulb (13.5), and dry weight (740.5 g/m-2).
Plants treated with 0 and 25 kg P/ha exhibited P deficiency symptoms
such as dwarfing and purpling of leaves. Broadcasting gave greater
plant height (61.3 cm), bulb length (3.42 cm), bulb diameter (3.35 cm),
clove breadth (3.15 cm), number of cloves per bulb (13.25), and dry
weight (661.3 g/m-2) than band placement.
