Online Published on 14 February, 2024. Abstract Due to the importance of citrus in Iran and the factors affecting their production, citrus orchards were the subject of different studies. Different environmental factors, especially the properties of soil and the bioavailability of essential nutrients in the soil play an important role in the growth and yield of plants. Balance of nutrients is vital to increase yield, improve quality and prevent contaminations. Severe deficiencies of nutrients such as calcium, boron, iron, zinc, and manganese have been observed in some areas. In the southern orchards of Iran, high concentrations of boron and calcium, iron, zinc, and manganese deficiencies have been observed. Deficiencies of boron, calcium, manganese, and zinc are evident in the northern orchards of Iran. In addition to these deficiencies, boron toxicity was reported in southern citrus orchards of Iran, especially Jahrom and Darab in Fars province. Most of this response was related to direct effect of boron concentration in irrigation water. Furthermore, boron toxicity in plants is the result of the accumulation of Boron in plant tissues which disturbs the normal growth and development of plants. Therefore, it is necessary to provide solutions to increase the growth and yield of citrus orchards through the management of the status of boron in the soil. The present work focuses on the status of boron in the Iranian citrus orchards and the management strategies for addressing the nutritional disorders related to boron.
