However, the appropriate space between poplar trees is essential to high-performance productivity in diverse regions. The present study monitored the effect of different spacing configurations (A: 4 × 3 m; B: 4 × 3 m (pure poplar); C: 6 × 3 m; D: 8 × 3 m; E: 10 × 3 m and F: pure crop) of poplar-based agroforestry with two canola (<em>Brassica napus</em> L.) and wheat (<em>Triticum aestivum</em> L.) cropping system on biomass production and carbon storage. Over the eight years, the total poplar biomass production was significantly different (<em>P</em> ≤ 0.05) in poplar-based configurations and ranged from 9.1 to 13.4 mg ha<sup>–1</sup>. The highest carbon storage of 6.5 mg ha<sup>–1</sup> was observed in configuration E. Crop production of canola and wheat in configurations B, C, D, and E, did not show a significant difference with pure crop cultivation, while configuration A was significantly lower. Our result indicated that configuration E, with the highest total biomass production but no significant difference in crop production, is the optimum system of poplar-based agroforestry in regions with similar temperate climate conditions of Northern Iran. Finally, poplar-based agroforestry provides high efficiency of carbon sequestration in trees which can conserve all market and non-market benefits.</p><p><strong>Keywords:</strong> aboveground biomass, carbon concentration, crop yield, productivity, <em>Populus deltoides</em>, Northern Iran</p> ER -
