Chickpea is one the most important legume crops in Mediterranean semi-arid regions and its sustainable production strongly depends on the nutrient management and water availability. Soils of these regions generally have high pH, and low organic matter, which reduce the availability of micronutrients and led to multi-micronutrient deficiencies. For estimating the effect of integrated application of different levels of organic fertilizer (zero, 20 t ha-1, 40 t ha-1) and micronutrient fertilizers (Zn, Fe) on agronomic traits and yield components of chickpea, an experiment was carried out at the highland semi-arid regions in Piranshahr district (36° 40ʹ N, 45° 08ʹ E; 1840 m). Assessment of phenological development revealed that plants grown under control condition (no-organic and micronutrients fertilizer) had a significantly slower development. Assessment of agronomic characteristics showed that application of micronutrients fertilizer substantially increased plant height, first pod height, canopy width, number of the seed, seed weight, economic and biological yield compared to control condition. By increasing the application rate of organic fertilizer its positive effects became more impressive on growth and yield component. The best growth performance was recorded by integrated application of 40 t ha-1 organic fertilizer and micronutrients fertilizers. However, there was no significant difference between fertilizer of Fe and Zn. Overall, the results indicated that the studied site is facing with micronutrient deficiencies and application organic fertilizer can noticeably improve the efficiency of micronutrients fertilizer. A quick and supplementary approach is therefore required for remedy of both Zn and Fe deficiencies in the short term. The finding showed that a substantial yield improvement is possible by integrated application of organic and micronutrient fertilizer.
