Abstract— Spinach (Spinacia oleracea), is an important cool season vegetable crop which is widely consumed due to its high nutritional content and eco-friendly techniques has a great role in enhancing the productivity and nutritional quality of spinach in context of human health and sustainable agriculture. Among different organic amendments, seaweed is an important organic extract which can be utilized effectively as biofertilizer in improving the vegetative growth in Spinach. The present study was carried out at Amity Institute of Organic Agriculture, Amity University Noida, UP to study the potential of seaweed extract, a bio stimulant on growth parameters in Spinach (Spinacia oleracea L.). Seaweed is an organic bio-stimulant, which is rich in vitamins, amino acids and phytohormones. The field experiment was conducted at the Amity Institute of Organic Agriculture in Randomized Block Design (RBD) with six treatments as 20, 40, 60, 80 and 100 ml were tested for its stimulative potential of plant growth.
