![]() ![]() Silicon has positive effect on the biomass yield under deficit irrigation. ![]() Silicon enhances growth and yield of all annual and vegetable crops, promotes upright growth (stronger and thicker stems, shorter internodes), prevents lodging, promotes favorable exposure of leaves to the light, provides resistance to bacterial and fungal diseases and decrease some abiotic stress as temperatures, salinity, heavy metal and aluminum toxicity.Īccording to science researches, silicon increase plant’s resistance to many plant diseases such as powdery mildew, septoria and eye-spot and also many insect pests. The beneficial effects of Si on plants have been demonstrated by many studies using pots, hydroponic, and field experiments. ![]() Inside plant, it travels to active growing points, where it complexes with an organic compound in the cell walls and makes them stronger. Plant assimilates silicon through roots as silicic acid. In nature, silicon occurs as the oxide (silica) and as silicates, in which it’s used in fertilizers. Despite the abundant benefits in agriculture, Si is generally not considered as an essential plant element. Since it exists in the Earth’s crust, many plants can accumulate it in large concentrations, in amounts similar to macronutrients. It’s used to make dynamo, engine blocks, machine tools, silicons, as crucial components in microelectronics and computer chips, as the most common component of sand and vital element for life in both plants and animals. Silicon is one of the most useful elements to mankind. Silicon is the seventh most abundant element in the universe and the second most abundant element on the planet, after oxygen, making about 25 percent of the Earth’s crust. ![]()
