“…The best result obtained might be related to differences in nutrient contents in both residues (Table 1), because the broiler manure based on sawdust contained higher levels of zinc (Zn), manganese (Mn), iron (Fe), calcium (Ca), magnesium (Mg), and phosphorus (P), which may have been more available throughout the plant cycle because of lower C/N ratio. The results were consistent with the reports by Torales et al (2014), who observed the elevation in P, K, and Mg levels in soil after broiler manure application for the production of commercial arracacia roots.…”

Organic residue addition to soil is a recommended practice for arracacia production. This study was aimed at analyzing the agroeconomic productivity of arracacia cultivated with different doses (0, 5, 10, 15, and 20 Mg ha −1) and residue types in broiler manure (sawdust and rice hulls). From the arrangement in a 5 × 2 factorial scheme, ten treatments resulted, in a randomized complete block design with four replications. The highest leaf mass production was obtained with 11.2 Mg ha −1 of broiler manure. The use of broiler manure containing sawdust at 16 Mg ha −1 resulted in the highest shoot and root productivities. The maximum numbers of shoots were 649,500 ha −1 and 651,560 ha −1 , with 12.48 Mg ha −1 and 9.20 Mg ha −1 of broiler manure containing sawdust and rice hulls, respectively. The maximum number of marketable roots was obtained by using 11.77 Mg ha −1 and 12.21 Mg ha −1 of broiler manure containing sawdust and rice hulls, respectively. The costs per hectare varied by R$ 3,233.55 between the lowest and highest costs. It was concluded that the highest productivity of marketable arracacia roots was obtained with 16 Mg ha −1 of broiler manure containing sawdust. The highest gross and net incomes were obtained with 15 Mg ha −1 of broiler manure containing sawdust.

“…The production costs were calculated by adapting the tables for 'Comum' arrowroot plants presented by Abrão (2016), as well as those for 'Amarela de Carandaí' Peruvian carrots reported by Torales et al (2014) and Heid et al (2015).…”

The global production of arrowroot is minimal, and this may be partially associated to the lack of standardized agronomic techniques for its commercial cultivation. This study aimed to assess the yield and profitability of arrowroot plants (‘Comum’ cultivar) grown using different plant spacings in the cropping row (20 cm, 25 cm, 30 cm and 35 cm) and a varying number of hilling applications (0, 1 and 2). The treatments were arranged in a 4 x 3 factorial scheme, in a randomized experimental block design, with six replications. After harvesting, the fresh and dry matter yields of leaves, rhizomes and roots were determined. Production costs and gross and net incomes were also calculated. The highest yields for fresh leaves (8.75 t ha-1), rhizomes (32.92 t ha-1) and roots (8.45 t ha-1) were obtained with a plant spacing of 20 cm. No interaction between the factors, neither significant differences for the use or not of hilling, were observed on the analyzed variables. The costs per hectare ranged from BRL 8,488.83 (35 cm without hilling) to BRL 10,376.23 (20 cm with two hillings). The highest yields and gross and net incomes were obtained with the spacing of 20 cm between plants.

“…The authors found no response regarding fresh mass of leaf and stem and concluded that species native to Cerrado are undemanding for fertilization. The positive response to organic fertilization in this study results from the different conditions of soil, climate, and others, it is, therefore, important to produce more leaf mass and consequently more secondary metabolites (Knapik et al, 2005;Torales et al, 2014;Trevizan et al, 2016).…”

“…In addition to intercropping, the use of organic waste as chicken manure, which is a primary source of nutrients, can contribute to reduce reliance on agricultural inputs, as well as to provide a sustainable destination for these materials (Torales et al, 2014;Rogeri et al, 2015). Organic manure can increase medicinal plant production by promoting slow and gradual release of nutrients to the soil over time and improving physical, chemical, and biological attributes of the soil such as reduction of soil density, increase in soil porosity, and increase in soil-water retention (Costa et al, 2009), increase in cation exchange capacity, increase levels of P, K, Ca, Mg, Cu and Zn (Rogeri et al, 2015), and increase soil microbial respiration (Andrade et al, 2015).…”
