Quality improvement and seed yield of two garlic cultivars (allium sativam l.)‎ by seaweed extract and mycorrhizae

Abstract EN

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
