Intercropping with Tropaeolum majus and fertilization with chicken manure on yield of Allophylus edulis

Abstract

ABSTRACT Proper crop management is essential for preservation of medicinal plants of the Cerrado. There is no report of ex-situ cultivation of Allophylus edulis (vacum), which is used for its antimicrobial and antioxidant activities, in intercropping with Tropaeolum majus (nasturtium). Therefore, the aim of this study was to evaluate the effects of the intercropping with nasturtium and fertilization with chicken manure on yield of vacum. The experiment consisted of six treatments: monocrop vacum without chicken manure; monocrop vacum with hicken manure; monocrop nasturtium without chicken manure; monocrop nasturtium with chicken manure; vacum intercropped with nasturtium without chicken manure and vacum intercropped with nasturtium with chicken manure. The crop cycle of vacum took 540 days after transplanting and, during this period, nasturtium was cultivated in two cycles, in 2017 and 2018. Vacum showed greater height growth and production of fresh and dry masses of leaves in single cultivation with chicken manure fertilization. Nasturtium showed greater growth and flower production in monocrop cultivation with chicken manure fertiliazation, in the first cycle. The intercropping vacum with nasturtium was effective, showing Equivalent Area Ratio (EAR) of 1.16 and 1.18 without and with chicken manure, respectively.
