Growth and Yield of Rice Plants Frown in Media Containing Several Formulations of Brown Algae Organic Fertilizer

摘要

It has been reported solid extract of brown algae contains essential elements, which can stimulate growth and yield of plants. Therefore, it can be used as an important source of organic fertilizer. This article reports several formulation of organic fertilizer on gworth and yield of rice plants. There were six formulations were tested, named with Al, A2, A3, B1, B2, and B3. Each formulation was different in content of solid extract of brown algae, chicken manure, rice husk and sawdust. The result shown that except plant other parameter, such as tiller number, shoot dry weight, root dry weight, penicle number, and grain weight, were affected by formulation of organic fertilizer. Formulation B3 containing only 5% solid extract of brown algae, increase growth and yield of rice plants. This suggests that the best formulation of organic fertilizer which can increase growth and yield of plants significantly should contain 5% solid extract of brown algae.
