Effect of Silica Fertilizer to Growth and Yield of Rice (Oryza sativa L.) in Jajar Legowo Method

Aims: The research aimed to study the interaction between Jajar Legowo method and silica fertilizer doses to growth and yield of rice.

Study Design: Factorial design in Completely randomized design

Place and Duration of Study: The research was conducted in farmer’s rice field in Linggo Sari Baganti, Pesisir Selatan, West Sumatera, Indonesia from July to Oktober 2020.

Methodology: Factorial design with 2 factors in completely randomized design was used in the research. The first factor was Jajar Legowo method that consisted of 3 degrees (2:1, 3:1 dan 4:1) and the second factor was silica fertilizer doses that consisted of 4 degrees (0 ml/L, 5 ml/L, 10 ml/L and 15 ml/L). The data was analysed using F test 5% and continued by Duncan’s New Multiple Range Test (DNMRT) 5%

Results: Generally, the interaction between Jajar legowo method and silica fertilizer did not affect the production of rice plant. But, for single factor both jajar legowo method and silica application affected the growth of rice plant

Conclusion: The production per hectare of rice plant was lower than description so that this method should be improved to obtain the better result.
