Effect of solid and liquid extract of Sargassum crassifolium on growth and yield of rice plant

The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment. Therefore, the use of organic ferlizer is increased recently. Many authors report that macroalgae is an important source of organic biostimulant and biofertilizer. This is due to the fact that liquid extract contains phytohormone, and solid extract contains essential elements, stimulating growth and production of plants. This article reports effect of solid and liquid extracts on growth and yield of rice plants. Liquid extract (10%) was sprayed during vegetative growth of the plants. On the other hand, liquid extract (5%) was applied directly to growth media. Then, the growth parameters (plant height, tiller number, shoot dry weight and root dry weight), and yield parameters (penicle number and grain weight), were measured during harvesting time. The results show that solid and liquid extracts of Sargassum crassifolium increased the growth and yield of rice plants. This indicates that solid extract of Sargassum crassifolium could be developed as a source of organic fertilizer. On the other hand, liquid extract of Sargassum crassiflium could also be used as a source of organic biostimulant. Both products should support suitable agriculture production.The excessive use of ingonaic fertililizer in agriculture system production reduces soil fertility and polluted out environment.
