Effect of Bio-Extract on Growth and Flower Yield in Jasmine (Jasminum sambac (L.) Ait.)

Abstract

Chemical fertilizer is widely used for plant cultivation including Jasmin (Jasminum sambac (L). Ait.) production. However, chemical fertilizer cause high cost and effect to quality of soil in long term use. Bio-extract fertilizer becomes one of the alternative compound for reduction of chemical treatment. The aim of current study was to apply the bio-extracts to cultivation of Jusmin and increase the quality and yield of the flower. The experimently was conducted at Kasetsart University, Sakon Nakhon province. Randomize Complete Block design (RCBD) was applied for this experiment with 6 treatments viz. bio-extract formulas of Azadirachta indica (neem), Pomacea canaliculata (apple-snail), Cucurbita moschta Decne. (pumpkin), Lemna minor (common duckweed), mixed plant shoots and control. Jasmin plant with apple snail formula bio-extract showed the highest height of stem (55.33 cm.). The plant fertilized with plant shoot formula had the largest number of branches (47 branches) and amount of flower per plant. However, all bioextract formulae did not affect to flower weight and length of flower bud. Therefore, the results indicated that mixed plant shoots formula was the most suitable bio-extract for cultivation of Jusmin in this study.
