Summary: | Organic cultivation of the medicinal species
Passiflora incarnata
L. is generally a requirement of the herbal industries. However, there is little information about the nutritional requirements of this species as well as about the effects of organic fertilization on its biochemical and physiological performance. This study evaluated the effect of two types of animal manure on the production of biomass and content of phenolic compounds with antioxidant activity in
P. incarnata
organically grown. The field experiment was carried out under sandy soil condition, with three types of fertilization (control: without fertilization; fertilization with cattle manure; fertilization with poultry manure) and 2 harvest seasons (first harvest at 90 days after seedling transplanting [DAT] and second harvest at 150 DAT). Chemical analysis of the soil was done for compare the initial and final conditions and foliar analysis were made to verify the leaf macronutrients (N, P, K, Ca, Mg, and S) content in each harvest season. The organic fertilization did not influence the production of aerial dry biomass, which presented an average of 1 ton ha
−1
for each harvest. There were no differences in leaf macronutrient contents between organically fertilized plants and control plants. The highest leaf contents of P, K, Ca, Mg, and S were observed at 90 DAT. Plants fertilized with cattle and poultry manures presented increases in the total phenol content and antioxidant activity in relation to the control plants (without fertilization), in both harvest seasons (90 and 150 DAT). In conclusion, fertilization of
P. incarnata
with cattle and poultry manure did not result in dry biomass gains, but promoted an increase in the quality of the raw material (higher phenolic concentration and antioxidant activity). |
