Abstract:
 

Local white garlic, Allium sativum L. cloves were planted during the first week of October for three seasons (1983/84, 1984/85 and 1985/86) in a heavy clay soil (pH 7-8) at Sennar Research Station experimental field. Cloves were planted in 80 cm ridges in one row per ridge at spacing of 20 cm between plants. Urea was added to provide 0, 95,190,286 and 381 kg N/ha and three irrigation intervals were applied 7,14 and 21 days. Frequent irrigation (7 days) significantly (P = 0.05) increased plant height, average bulb weight, number of cloves per bulb, percentage of dry weight and total bulb yield. The levels of added nitrogen significantly (P= 0.05) increased average bulb weight, the weight of 100 cloves and total bulb yield up to 286 kg N/ha after which the response was negative. The highest yield was obtained from the addition of 190 kg N/ha with 7-day irrigation interval.
