ABSTRACT Different cultivation methods directly affect the quality of medicinal materials, to gain insights into the effects of different type of mulching on the quality of Notopterygium franchetii root medicinal materials, farmland experiments were conducted in the Qinghai-Tibet Plateau. We subjected two-year-old Notopterygium franchetii seedling to five mulching treatments: no mulching (CK, control), coarse sand mulching (CM), grassy mulching (GM), stalk mulching (SM), and plastic mulching (PM). Following these treatments, we determined the moisture content, pH, NPK contents, and enzymeatic […]

The effects of applying micronutrients, cattle manure, lime and splitting application of NPK fertilizers on the yield and the incidence of witches’ broom disease of cacao caused by Crinipellis perniciosa were determined in two experiments carried out on structured Terra Roxa soil (TR) and Yellow Latosol (LA), in Pará State, from 1988 to 1993, after the slash and burn of the forest. The hybrid (Sca 6 x Be 10) cacao crop was introduced utilizing banana (Musa spp.), as temporary shading, […]
