Low-cost organic fertilizations and bioactivator for arugula-radish intercropping

Abstract

The objective of this study was to evaluate the effects of boiled chicken manure doses (via fertigation), bokashi and Penergetic bioactivator on radish-arugula intercropping production variables. The treatments were control, Penergetic, Bokashi (9 g per plant), and boiled chicken manure (BCM) on 2.5, 5.0, 7.5 and 10% concentrations in water, for fertigation. The following variables were analyzed: leaf biomass (LB), leaf length (LL), for both plants. Bulb fresh biomass (BB) and bulb volume (BV) variables for radish only. A completely randomized design with nine replicates was used for first and second crop cycles, and five replicates, for third crop cycle. All production variables were influenced by the treatments, except radish LL, on third cycle. Bokashi increased production variables of arugula and radish. Penergetic increased radish bulb biomass (two cycles, only) and bulb volume. BCM increased arugula biomass at 10% and radish bulb biomass at 7.5% on three crop cycles, and with BCM concentration at 5, 7.5% and 10% bulb volume was increased (two crop cycles, only).
