Gartic bulblets were planted to investigate the effect of some different cultivating conditions on the growth and bulb formation of the garlic plants (Allium sativum L.) Two different conditions namely perfect and imperect aerobic condition, and 3 different fertilizer levels was made. The split plot design was adopted for this experiment. 1) For the growth rate, under the imperfect aerobic condition, the plant height was more increased than that of perfect aerobic condition no relation to the fertilizer levels. 2) With respect to the fresh weight of garlic, the similar tendency to the growth rate was observed, but dry weight was did not. 3) The uptake of phosphorus was found to be increased in the imperfect condition. It could there be concluded that imperfect aerobic condition seems to be much favorable condition than the perfect aerobic condition to the development of garlic bulbs.
