This research experiment was carried out in Bsaisin, Jableh region, during the agricultural season 2022-2023. It aimed to study the effect of spraying seaweed extract and EM1 on vegetative growth and production characteristics in lettuce plant (Lactuca sativa<\/em>.L). In depends on the Randomize complete Block Design (RCBD) Full with five treatments and three replication for each treatment, and 15 plants per replication, the treatments were: spray plants with water only (Control) -Spray plants with seaweed extract (1 ml\/l) – Spray plants with seaweed extract (2 ml\/l) – Spray plants with EM1 (5 ml\/l) – Spray plants with EM1 (10 ml\/l). It was noticed that spraying Lactuca sativa. L plants with seaweed extract (1 ml\/l) and EM1(10 ml\/l) increased all the indicators studied (vegetative growth and production characteristics) as compared to the control treatment with significant differences. Our results showed the positive effect of foliar spraying with EM1 10 ml\/l on lettuce plant, achieving an increase in the representative surface area (6666) cm2<\/sup>, head weight(934) g, and production quantity(7.8) kg\/m2.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/p>\n
