Zinc improves the growth of rice plants

A member of the faculty of the National Rice Research Institute said: the presence of zinc in rice soil is effective in improving grain growth in this plant.

Shahram Mahmoud Soltani, today in a scientific lecture at the Iranian Rice Research Institute, regarding the changes in various forms of zinc due to the use of phosphorus, lime and zinc in paddy soils with zinc deficiency in the tropics said: It depends on the equilibrium between the various forms of the element zinc, and this equilibrium is influenced by the geochemical conditions of the soil.

Referring to a study conducted to investigate changes in the different forms of zinc in six series of tropical paddy soils (two soil categories) under the influence of different levels of phosphorus, lime and zinc fertilizer, he added: In this method, sequential extraction of soil after They have been used for 30 days of incubation under water immersion conditions.

Mahmoud Soltani continued: All forms of zinc increased with increasing zinc treatment and soluble forms plus its exchange and organic form decreased with increasing phosphorus levels and application of lime, while the forms attached to amorphous and manganese oxides and the remaining fractions increased with increasing The level of functional foundation and lime has increased.
This behavior was the same in all used soils, except for their differences in physical and chemical properties.

The faculty member of the National Rice Research Institute stated: Also, the simultaneous use of phosphorus and lime, compared to their use alone, leads to a further reduction of the soluble part, in addition to the exchange and organic form of zinc.

He added: The results of this study can be used to manage the element zinc in rice soil in tropical regions to improve the growth of rice plants and enrich zinc in its grain.
