Pechay (Brassica pekinensis) is used mainly for its immature, but fully expanded tender leaves as main ingredient for soup and stir-fried dishes. It is one of the major vegetables produced in the Philippines. Due to a great demand in the local market, there is a need to increase production of pechay by enhancing the fertilizer program. Stimulate yield enhancer is a biostimulant containing natural plant growth regulators and chelated trace minerals. These phytohormones are cytokinin, gibberillic acid, and indole-3-butyric acid. Stimulate enhances plant growth and development by stimulating cell division, cell differentiation and enlargement, nutrient uptake, and nutrient utilization. Stimulate hormones increased plant height of pechay by 37%, length of leaves by 44%, width of leaves by 39%, fresh weight by 2 times, yield by 3 times, and number of leaves.
