Abstract

Many reserches reported that brown algae is main source of by fertilizer and biostimulant for supporting growth and development of agriculturaland horticultural plants. This article reports growth and yield of rice plant sprayed with different concentration of Sargassumpolysistum, one of brown algae species. Since the age of rice plant was 21 days after planting. The plants were sprayed with 0, 5, 10,15, 20% of Sargassumpolysistum extract. The plants were sprayed one a week during vegetative growth. The results show that concentration of Sargassumpolysistumincreased the growth of rice plants until maximum concentration 10%. However, when this extract applied in more than 10%, the growth was decreased similar phenomena was also demostrated in yield parameters, such as penicle number and seed weights.
