Abstarct: Carbon sequestration could be an effective way to reduce atmospheric carbon dioxide which is the most important greenhouse gas. In order to evaluate the effects of different tillage and nutrition management systems on yield and yield components, net primary productivity, some soil properties and carbon sequestration potential in cultivation of maize (KSC 704), an experiment was carried out at Faculty of Agriculture of Shahrood University of Technology in growing years of 2015-2016 and 2016-2017. The experiment was conducted as a split plot arranged in a randomized complete block design with three replications. The tillage systems used in the main plot were conventional tillage (moldboard plow + disc) and reduced tillage (chisel plow), and nutrition management was applied on the sub plot. Seven nutrition management were: control, chemical fertilizer (300 kg.ha-1 urea and 100 kg.ha-1 triple superphosphate), manure (20 ton.ha-1), biochar (20 ton.ha-1), chemical fertilizer + manure (150 kg.ha-1 urea and 50 kg.ha-1 triple superphosphate + 10 ton.ha-1 manure), chemical fertilizer + biochar (150 kg.ha-1 urea and 50 kg.ha-1 triple superphosphate + 20 ton.ha-1 biochar) and manure + biochar (10 ton.ha-1 manure + 20 ton.ha-1 biochar). The results showed that in both years, nutrition management had significant effect on yield and yield components, seed nutrient uptake, aboveground and belowground net primary productivity. In the first year, chemical fertilizer + manure and chemical fertilizer + biochar increased seed yield (60.41 and 56.32 percent), aboveground net primary productivity (47.04 and 42.69 percent) and seed nitrogen uptake (83.95 and 81.38 percent) compared to control, respectively. In the second year, chemical fertilizer + manure as well as increased seed yield and aboveground net primary productivity by 51.43 and 47.05 percent compared to control, respectively. In the second year, maize yield in chemical fertilizer + biochar differed from chemical fertilizer alone and chemical fertilizer + manure. Nutrition management had significant effect on soil moisture, basal respiration, total nitrogen, available phosphorus, organic matter, carbon management index and soil carbon sequestration in both years. In the second year, manure and chemical fertilizer + manure increased organic matter (28.31 and 17.06 percent), carbon management index (40.38 and 33.35 percent) and soil carbon sequestration (36.80 and 22.99 percent) compared to control. However, there was no significant difference between chemical fertilizer + manure and manure. baxsed on the results, there was no significant difference between conventional and reduced tillage. As well as due to the negative effects of chemical fertilizers on the physical, chemical and biological properties of soil and the high cost of these inputs must be attended to nutrition resources to improve soil properties and environment protection. Therefore, the reduced tillage with nutrition management including chemical fertilizer + manure is recommended for improvement of yield, yield components and carbon sequestration in maize cultivation
