Ipecacuanha [Carapichea ipecacuanha) (Brot) L. Andersson] has a high commercial value due to the presence of emetine and cephalin in its roots, which can be enhanced by different levels of light intensity. This study aimed to study the physiological response of ipecacuanha plants under different shading levels (50, 70, and 90%) in all seasons. Plants were cultivated in a greenhouse with sombriteVR (shading) for 395 days, in beds containing sandy soil, after which we evaluated chlorophyll (Chl) a fluorescence, photosynthetic pigments and emetine and cephalin. Chl a fluorescence was higher in plants under 50% shading in all seasons while plants under 90% shading showed increases in Chl a fluorescence in the summer. The changes in Chl a fluorescence under 50% shading reveal difficulties in adaptation to high light levels, since high light intensity causes disorders in the dynamic dissipation of photosynthetic energy, and a decrease in photosynthetic pigments. The highest content of cephalin was recorded in winter under 70% shading, whereas for emetine it was recorded in spring, under 90% shading. Autumn (70% shading) was the only season in which the amount of both emetine and cephalin was similar. Therefore, both the season and the shading level affect ipecacuanha metabolism. |

Intercropping corn and palisade grass is a technique to increase straw production, soil C contents, nutrient cycling and crop yield. However, concerns arise from nitrogen (N) uptake by the intercropping crop causing reduction in the yield of the corn. Our objective was to evaluate N recovery efficiency (NRE), and the N dynamics in the soil-plant system in corn intercropped with palisade grass. A field trial was carried out in Bahia, Brazil, evaluating two cropping systems: corn (monoculture) and corn intercropped with palisade grass sowed between rows on the same day as the corn crop, with four replicates in a completely randomized block design. Nitrogen (150 kg∙ha?1of 15N-urea) was applied at sowing to determine NRE, which means the amounts of N-fertilizer uptake in corn and palisade grass, the amounts of N-fertilizer in soil and the 15N-fertilizer balance. Neither the NRE (63.3% in monoculture and 57.2% in intercropping) nor corn grain yield (9,800 kg∙ha?1 in monoculture and 9,671 kg∙ha?1 in intercropping) was affected by intercropping, which accumulated only 2.1 kg∙ha?1 of N-fertilizer or 1.4% N rate. In addition, palisade grass yielded 2,265 kg∙ha?1 of dry matter. The balance indicated that 82.4% of N-fertilizer was recovered in the monoculture and 86.9% in the intercropping. Intercropping palisade grass does not affect grain yield or N corn nutrition and has the potential to increase straw production contributing to maintenance of no-till. |
