Resumo: |
The development of a crop is entirely connected to the soil conditions, climate, relief, water availability and nutrients. This work has as objective to evaluate the productivity of grains and the oil revenue of crambe cultivation under different nutritional arrangements with base on NPK. The experiment was carried out in the city of Cascavel PR, in the experimental area of the school farm of FAG Faculdade Assis Gurgacz, in tipical distroferric red latosoil, argillaceous to very argillaceous texture, lightly wavy relief, and average altitude of 680m. The climate of the region, according to climatic classification of koppen is humid mesothermal (Cfa). The treatment consisted of nutritional arrangements with base in NPK, being: T1: NPK; T2: N; T3: P; T4: K; T5: NP; T6: NK; T7: PK and T8: witness (without fertilizing application). The experimental delineation used was entirely randomized with 8 treatments and 3 repetitions. The cultivation in bands was used, being 3 bands of 4.8 x 68 meters long. The experimental unities consisted of 4.8 meters wide by 6.0 meters long each. The productivity of grains was performed from the harvest of an area of 1.0 square meters done in the central parts of the experimental unities. The oil revenue was made utilizing the Soxhlet method, in which the oil is extracted from the grains through successive washing with organic solvent. The statistical analysis consisted of the analysis of variance and the averages of treatment were compared by the test of Turkey to 5% of significance. Also the analysis of linear regression was made between the grain productivity data and oil revenue to verify the correlation between these variables. No isolated or associated nutrient promoted significant difference for the productivity of grains. For the oil revenue, the compost arrangement of NPK promoted significant difference from the other treatments, with exception from the NK and P treatment. The oil revenue is more associated with the quality than with the quantity of grains in the crambe cultivation. |
