Phenology of Hyptis pectinata and effects of cattle manure and cutting height in management of its cultivation
The species Hyptis pectinata (Lamiaceae) is found in America, West Africa, and India. In Sergipe State, Brazil, it occurs naturally along roads and at edges of forests. It is a widely used medicinal plant in this State and is commonly known as sambacaitá or canudinho. It is used by the local population for treatment of inflammation and bacterial infections, but the material used is obtained through extractivism. The aims of this work were to study the phenology of H. pectinata and to evaluate the influence of cutting heights and levels of cattle manure on biomass and essential oil production. Under the conditions of Sergipe State, Brazil, we observed that flowering of H. pectinata plants begins in late July, during the rainy season. In early October, the seeds were spread; at the end of October, we observed senescence. We concluded that H. pectinata is an annual plant. H. pectinata supported three harvests, and cutting at 20 cm from soil surface resulted in better regrowth. The application of cattle manure is not a limiting factor for H. pectinata cultivation.
