Phytostimulatory Potential of Turan Biostimulant on the Growth and Yield of Brassica rapa subsp. chinensis (Pechay)

The growth and yield of pechay affected by Turan Biostimulant under field conditions were studied in Oogong, Sta. Cruz, Laguna Philippines to evaluate its effects and determine its best level for the optimum growth and yield of pechay. Turan is a patented high-analysis formulation with plant nutrients complexed by bioactive polyphenols that enhances nutrient availability to plants and provides a biostimulant effect to improve plant vitality and activate natural bio-defenses to protect the plant from stresses. There is a need for a plant food supplement that can promote quick nutrient absorption in the organic pechay production process, thus a randomized complete block design with four replications experiment was conducted. Parameters such as total fresh yield, marketable yield, non-marketable yield, plant height, number of leaves, leaf width, and root length/biomass were gathered from a sample of 40 plants per treatment (10/rep) and analyzed using statistical methods. The study showed that the test product was able to slightly enhance pechay production in terms of total fresh yield, plant height, leaf length, leaf width, root length, and root biomass with an estimated increase of more than 1.18%, 1.06%, 1.04%, 1.03%, 1.13%, and 1.12%, respectively, compared to inorganic fertilizer application alone. In general, pechay is very responsive to granular fertilization and the application of Turan biostimulant. The findings also showed that the addition of a biostimulant would further enhance the amount and quality of harvested pechay. One and a half doses of Turan biostimulant, or even more, is strongly recommended in terms of its viability in pechay cultivation to maximize profits.
