Effect of foliar spraying with micronutrients and salicylic acid on growth, yield and quality of garlic plants

الملخص EN

Two field experiments were carried out during the two seasons of 2011/ 2012 and 2012/2013 at the Experimental Farm of South Tahrir, Horticulture Research Station, Ali Moubarak Village, El-Bostan area, Behiera Governorate to investigate the effect of micronutrients mixture concentrations (Cont., 10, 15 and 20%) and three foliar application of salicylic acid (0,150, 300 ppm)as well as their interactions on growth, chemical constituents and bulb yield and its components of garlic plants (Balady cv.)grown in sandy soil under drip irrigation system.

The obtained results showed that the foliar spraying with 20 % micronutrient or 300 ppm salicylic acid were the best treatment for increasing plant height, number of leavesplant-1,plant fresh weight, both bulb weight, diameter and total yield fed-1 of garlic plants.

Results ,also, showed that foliar application of micronutrients improved the total chlorophyll, bulb dry matter, N and K contents in bulbs and as well as total soluble solids in bulbs, in both seasons.

The best results of vegetative growth, yield potential and chemical constituents were achieved when garlic plants were sprayed of 20 % micronutrient and 300 ppm salicylic acid.
