Abstract
Abstract Chickpea is one of the most important legume crops in the Mediterranean semiarid regions. Soils of these regions generally have free CaCO 3 , high pH and low organic matter, which reduce the availability of micronutrients and cause their deficiencies. In order to study the effects of integrated application of different level of elemental sulfur (0, 15, 30 kg·ha −1 ) and nano-chelated micronutrients (Zn, Fe, Mn) on growth and agro-morphological traits of chickpea ( Cicer arietinum L.), a field experiment was conducted in the semiarid regions of the northwestern part of Iran. Evaluation of morphological traits showed that application of high level of sulfur significantly improved plant height, the number of primary branches and canopy width compared to the control. The longest growth period was recorded for plants grown by application of high level of sulfur and nano-chelated Zn fertilizer. The obtained data revealed that application of nano-chelated Zn fertilizer resulted in a significant increase in seed number per plant and seed weight compared to other nano-micronutrient fertilizers. Overall, the best growth performance and the highest seed yield were obtained from the integrated application of Zn and high level of sulfur. The findings showed that soil micronutrient deficiencies are partly due to high alkalinity of the soil, and application of sulfur beyond 15 kg·ha −1 can be an effective method to increase the efficacy of nanofertilizers. Integrated application of micronutrient and sulfur should be considered as an efficient agronomic management option for chickpea production systems in semiarid region.
