The present work was carried out at a private farm in sharnoob village, Damanhur city, Behira
governorate, Egypt, during successive seasons of 2015/2016 and 2016/2017. The present study aimed to
investigate the effect of some bio- stimulants (seaweed extract and mycorrhiza fungi) application on the
vegetative growth, yield and its component of two garlic cultivars (Balady and Sids 40). Eight treatments of
bio- stimulants were used; i.e., T1=Foliar application with tap water (control),T2=Foliar application with
seaweed extract at rate 3ml/L,T3=soaking with seaweed extract at rate3ml/L,T4= soaking and foliar
application with seaweed extract at rate 3ml/L,T5=Inoculums mycorrhizal in soil and covered in soil, T6=
Foliar application with seaweed extract at rate3ml/L + inoculums mycorrhizal in soil and covered in soil,
T7=soaking with seaweed extract at rate 3ml/L +inoculums mycorrhizal in soil and covered in soil and
T8=soaking and foliar application with seaweed extract at rate 3ml/L + inoculums mycorrhizal in soil and
covered in soil. The results indicated that significant difference between the two tested cultivars, where Sids
40 cultivar had thick nick diameter, bulb diameter cm, bulb fresh weight g/ plant, total yield / faddan, N%, P%
and K% contents of bulbs in both season. The best results also were given when T3, T5 and T7 treatments
application on the most tested characters. The interaction between two garlic cultivars and bio- stimulants
treatments show significant effect on all the studied garlic characters. In general,T3=soaking with seaweed
extract, T5= inoculums mycorrizal in soil and covered in soil and T7= soaking with seaweed extra at rate
3ml/L +inoculums mycorrhizal in soil and covered in soil can be recommended for achieving better
vegetative growth and higher bulb yield of the garlic plants, particularly, Sids 40 cultivar.
