Enrichment of rice (iron and zinc) with Plexomin iron and zinc plant fertilizers
Increasing population and increasing per capita demand for agricultural products, especially rice, and the lack of the possibility of a significant increase in the area under rice cultivation, the use of chemical fertilizers to repair the inherent capacity of the soil to provide nutrients is needed. Zinc (Zn) is the most important trace element, the deficiency of which is the most widespread and serious nutritional disorder in the world's paddy lands. Zinc deficiency After nitrogen, phosphorus and potassium deficiency has the most negative effect on the growth and performance of rice plants. This element plays an essential role in many metabolic processes in plants and is a vital compound in the structure of functional enzymes such as dihydrogenase, proteinase, peptidase, phosphohydrolase and carbon anhydrase. Zinc is also involved in auxin metabolism, chlorophyll accumulation, protein synthesis and starch. Therefore, its deficiency in soil has a negative impact on plant growth and development, and in this way puts a lot of economic pressure on farmers' incomes and crop production. As a result, the lack of available zinc in the soil causes a reduction of nearly 40 to 80% in rice grain production. The main food of the international community, especially in developing countries, is highly dependent on cereals, which in many cases are deficient in zinc. Rice (Oryza sativa L.) is the staple food of nearly three billion people in the world, especially in Asia and Africa, where 90% of rice is produced and consumed, and rice provides 70% of the calories and 25% of the protein they need.
Due to the fact that zinc and iron have an undeniable effect on increasing rice yield, bio-fortification or increasing the amount of zinc and iron absorbed and available in the food sector of agricultural products is an important and vital goal. Another is that by improving the quality and nutritional value of these products, many disorders caused by malnutrition in humans can be controlled (Mayer. Zinc deficiency and its disorders affect about 25% of the human population. Zinc plays a very key role in the human growth cycle such as physical growth of organs, immune function, nervous system and reproduction, puberty and health development. Zinc is an essential low-consumption element in human growth and development. Consumption of 110 grams enters the body of an adult human is about 2.4 mg, almost all of which is supplied by the soil and plant system (Welch, 2002). Leaf nutrition as a means to supplement the various amounts of trace elements and High consumption, plant hormones, resistance to diseases and pests, improving drought tolerance and increasing the quality of Mayb products Ashd. The reaction of the plant depends on the species, the form of fertilizer used, the concentration, the frequency of foliar application and the growth stage of the plant. One of the interesting advantages of foliar application is the increase in the absorption of elements from the soil. This is because foliar application causes the plant to pump more sugars and secretions into the roots. Beneficial microbial populations in the root environment are stimulated by increasing these secretions and increase access to trace elements, disease suppressants, vitamins and other plant-beneficial substances, so it seems essential that the effect of zinc and iron chelated with the amino acid glycine (Produced by Pak Gostar Parand Company) In comparison with the chemical source of zinc sulfate, the yield and yield components of Hashemi cultivar rice as well as the accumulation of ohm and zinc in the grain of this rice cultivar should be investigated.
Phosphorus) needs to be met by implementing a two-year project. Also, this experiment is performed with the aim of investigating the reaction of Hashemi and Gilaneh cultivars to the application of phosphorous element in terms of important agronomic traits and determining the appropriate amount of the element.
