Field efficacy of Semia biostimulant on the growth and yield of Pechay(Brassica rapa subsp. chinensis)

A field efficacy trial was conducted to assess the effect of Semia biostimulant on pechay in the farmer’s field. Variables such as plant height, leaf length, leaf width, number of leaves, root length, and root biomass have increased by as much as 2.46, 2.47, 8.08, 3.61, 17.52, and 56.93%, respectively, relative to inorganic fertilizer treatment alone. In terms of its feasibility in pechay production, 3 L/ha foliar spray of Semia biostimulant in addition to inorganic fertilization is recommended to increase yield by 32.12%.
