Abstract :

Spray of silicon fertilizer has common in field of rice production affected by salinity. In order to study of effect of liquid silicon fertilizers on yield of Anbarbo rice variety in salty soil of Ghaemiheh village of Bahnamier, a field experiment was carried out with three replicates base on random completely block design. 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. Characters of plant height, panicle number per hill, filled, empty and total grains per panicle, 1000-grain weight and yield were measured at physiological maturity stage. The results showed that spray of liquid silicon fertilizer with 6 ml/L was caused increasing of plant height and decreasing of empty grain per panicle. Potassium silicate fertilizer was caused more panicle number per hill. The highest total grain per panicle was obtained in nano silicate fertilizer of 6 ml/L. Using of silicon fertilizer was increased 10-20 percent of yield and yield components. The highest yield was related to liquid silicon fertilizer with 6 ml/L treatment (3265 Kg/ha). Efficiency of liquid silicon fertilizer was more than nano and potassium silicate fertilizers.
