تاثیر کود های مایع سیلیکاته بر رشد و عملکرد برنج رقم عنبربو در منطقه بهنمیر

Rice crop needs more silicon element than nitrogen but using of silicon fertilizer has not common in rice production. In order to study of effect of liquid silicon fertilizers on growth and yield of Anbarbo rice variety, a field experiment was carried out with three replicates base on random completely block design in Ghaemiheh village of Bahnamier. Treatment included liquid silicon fertilizer, nano silicon and potassium silicate with 2, 4, 6 ml/L concentration and check (no using silicon) were total 10 treatments. Silicon fertilizer spray was done at 25 and 50 days after transplanting. The characters of plant height, tiller number, leaf area and total dry weight were measured at maximum tillering, flowering and physiological maturity stages. The results showed that silicon spray was increased plant height and total dry weight at flowering and physiological maturity stages, however, had not affect at maximum tillering stage. Leaf area was increased with silicon spray at maximum tillering and flowering stages. The treatment of 6 ml/L of silicon fertilizer was caused increasing of growth and yield of Anbarbo rice variety about 10-30 percent compared to check.
