EFFECT OF SILICON FERTILIZER APPLICATION METHOD TO MAIZE GROWTH AND YIELD AT PSAMMENT SAMAS abstract a PlTf ftWs research is to investigate the effect ofsilicon fertilizer dose and efective method to growth so it can increase maize production at psamment samas The design used was factorial completely randomized design The first factor is silicon fertilizer dose 0 g m2 50 g m2 lOOg m2 200g m2 the second factor is fertilizer application method which consist of furtigation spot placement and foliar application fhe soil type used was psamment which has low concentration ofSi The treatment has three repeatition so there were 36 pots with 12 treatment combination The result showed research that fertilization method did not give significant effect to result and growth as a whole but giving significant effect to hight plant mean while it did not give an effect to the dry weight of trubus The method which gives effect to maize sleaferectivity but did not give significant effect to absorption efficiency Spot placement with dose fertilize 200 gSi m2 give result ofhight absorption efficiency Addition ofsilica 200 gSi m2 at Samas psamment can improve the availibility of silica and yield silica available in compared to highest land oftreatment without Si addition Keyword method silicon maize psamment fm XI iViEFFECT OF SILICON FERTILIZER APPLICATION METHOD TO MAIZE GROWTH AND YIELD AT PSAMMENT SAMAS abstract a PlTf ftWs research is to investigate the effect ofsilicon fertilizer dose and efective method to growth so it can increase maize production at psamment samas The design used was factorial completely randomized design. The first ...factor is silicon fertilizer dose 0 g/m2, 50 g/m2, lOOg/m2, 200g/m2. the second factor is fertilizer application method which consist of furtigation, spot placement and foliar application fhe soil type used was psamment which has low concentration ofSi. The treatment has three repeatition so there were 36 pots with 12 treatment combination. The result showed research that fertilization method did not give significant effect to result and growth as a whole but giving significant effect to hight plant mean while it did not give an effect to the dry weight of trubus. The method which gives effect to maize sleaferectivity but did not give significant effect to absorption efficiency. Spot placement with dose fertilize 200 gSi/m2 give result ofhight absorption efficiency Addition ofsilica 200 gSi/m2 at Samas psamment, can improve the availibility of silica and yield silica available in compared to highest land oftreatment without Si addition Keyword: method, silicon, maize,psamment. fm.
