RESUMO:

The importance of knowing in detail the vegetative development of a crop is related to technical and scientific strategies, both for technical decision-making (eg management) and also to estimate the contribution in the inventory and cycling of nutrients in the soil. The present work evaluated the biomass (above and below the soil) and the carbon stock in the soil in commercial plantation of interspecific oil palm hybrid (Elaeis oleifera cortés x Elaeis guineensis jacq.), Cultivar BRS Manicoré, in the municipality of Moju, northeast of the state of Pará. The interspecific hybrid of oil palm has been planted in regions with limitation to other cultivars due to the occurrence of the fatal yellowing anomaly. Roots and soil samples were obtained by collecting monoliths in two trenches, one with management influence (trench of road) and the other without influence of the management (trench between plants) with 4 meters in length, 50 cm in width and 60 cm deep. Monoliths were collected in layers 0-29015 (layer A), 15-30 (layer B) and 30-60 cm (layer C), 60-90 cm (layer D), and every 50 cm depth until reaching a total of 290 cm (layers E, F, G and H). In each layer, 8 monoliths were collected. In the laboratory, the roots were classified according to their diameter in primary (≥5.0 mm), secondary (1- 4.9 mm) and tertiary (0.5-0.9 mm) and quaternary (0.25 a 0.49).
