Abstract

Awareness of the nutritional status of trees will help Balanced fertilization. The average yield per hectare of lime orchards in the country, compared to the global average, is low, partly as a result of nutritional imbalance. DRIS method can be used to knownutrient status of orchards. In this method, an index is used that indicates the nutritional status and nutrient deficiency or excess, and allows prioritizing nutrients need for plants. In this study, lime orchards in three important areas of the province, namely, the Hashtbandi, central Minab, and Roudan were selected. Samples of the leaves were analyzed and yield measurements were done in 60 orchards. According to the DRIS indexes obtained in this study, nutritional status of the lemon orchards in the main production areas of the province were evaluated. The average of DRIS index for macroelements i. e. nitrogen, phosphorus, and potassium was-6. 07, 0. 81 and-2. 68, respectively. Thus, the priority of the Macronutrients needs was N> K> P in lime orchards of the province. The average of DRIS index for microelements including manganse, iron, boron, zinc, copper, and chloride was-8. 79,-6. 10, 2. 6, 4. 89, 7. 66 and 8. 21, respectively, thefore, nutritional priorities for Micronutrients was Fe> Mn> Zn> Cl> B> Cu. The overall priority of nutrients deficiencies was obtained as Mn> Fe> N> K > P B> Zn> Cu> Cl. According to the results, appropriate decisions can be made in order to balance fertilization. In these orchards, it is recommended that consumption of Micronutrients such as manganese and iron, and macroelements like nitrogen and potassium be at a higher priority.
