| description | The effect of phosphoric rock (RF) from the Media Luna mine in Huila and the products of the processes of acidification and kilning, as sources of readily available phosphorus on the production of the corn variety ICA-V305, and its assimilation by the plant-soil system. The experimental units were constituted by sandy soil mix, 15% pig manure compost, 10% rice husk, distributed in treatments like this: T1, no phosphorus, T2, 100 g/plant of 30P-Phosphorite, T3, 100 g/plant of partially acidified RF 20 mesh, T4, 100g/plant of partially acidified RF 100 mesh, T5, 100g/plant of kilned RF, T6, 100g/plant of kilned RF with serpentine and T7, 100g/plant of DAP. An experimental design was applied totally at random with 7 different treatments and 9 iterations whose response variables were: dry matter yield (MS), plant height (AP), median stalk diameter (DT), phosphor content in foliage corn tissue (CFM) and ground phosphor content (CFS). The best morphological features and vegetative development in corn were achieved with 30P-phosphorite and partially acidified RF, the best yields at harvest season were obtained with partially acidified 100-mesh RF and DAP with an average of 7.8 metric tons per hectare, without significant differences at 5%. Lesser yields were registered and significant differences with the usage of 30P-phosphorite, kilned phosphoric rock and the reference sample. Para citar este artículoTorrente, A. (2014).
