Abstract

Studies on growth, yield and N,B and K in Al-Hassawi andChinese garlic CVS were carried out during 1997/1998 and 1998/1999 season, Seedling were soaked for 30 minutes in gibbrellic acid (75and 150 ppm) indole acetic acid (500 and 1000 ppm) and boron (50 and 100 ppm) . Cloves methods culture was included for comparison with seedling planting methods. All treatments gave a significant increase in plant height, dry/fresh weight %, number of cloves/bulb, average bulb weight, total yield,and N,B and K content of leaves in both seasons .Cloves planting method gave 800.0 gm bulb weight /plant of Al-Hassawi cultivar and 1200 gm bulb weight/plant of Chinese cultivars, while seedling planting methods treatment with GA3 at 150 ppm gave 775.0 gm bulb weight/plant of Al-Hassawi cultivars and 1088.0 gm bulb weight/plant of Chinese cultivars.
Finally, cloves planting method and seedling methods after soaking with GA3 at 150 ppm (30minutes) coulde be useful for inhancing garlic bulb yield and it’s quality. Seedling methods might be recommended to decrease the period of the garlic growth in field by about two months which woulde decrease the area devoted for garlic production
