“…The observation that the highest productivity obtained in this study was lower than the national average, which is 9.3 t ha −1 (Madeira and Souza, 2004) and maximum productivity obtained in other experimental studies conducted in Dourados, including 14.0 Mg ha −1 obtained by Torales et al (2010) and 22.08 Mg ha −1 obtained by Heid et al (2015), but they are in agreement with Heid et al (2019), that is, average productivity (6.30 Mg ha −1 ), a might be related to maximum temperatures above 32ºC and an average of 26.5ºC from September on wards (Figure 1), when the phase of extensive translocation of reserve photosynthates from the aerial parts to roots (Graciano et al, 2006) occurs in addition to the thickening and characterization of marketable roots until harvest.…”

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.

“…These results show that detailed economic analysis is essential to understand how farming production activities can be exaggerated to boost profits (Heid et al, 2019). Besides, research with other root and tuberous crops, such as Jerusalem artichoke, suggests a demand to commercialize several parts of the plant to make a farming operation profitable (Johansson et al, 2015).…”

Yacon (Smallanthus sonchifolius [Poepp.] H. Rob., Asteraceae) is an Andean plant being explored as a functional food, due to high concentrations of fructooligosaccharides (FOS), a natural sweetener capable of reducing blood lipids and glucose levels, supporting prevention of chronic diseases, such as diabetes. Yacon commercial production is still being established, thus cropping practices and their impact on profitability are yet poorly explained. Improved planting recommendations are demanded, as it affects crop yield. In this background, a field trial was conducted to determine row spacing and plant populations for yacon production in tropical highland areas. The experimental design was a randomized complete block, in a split-plot scheme, where blocks were three row spacings (0.8, 1.0 and 1.2 m) and subplots covered three spacings between plants (0.4, 0.5 and 0.6 m), with four replicates. At harvest time, evaluations on accumulation of dry mass in the plant and tuber root production data (number, weight, total productivity, and per class) were made. Profitability indicators were estimated (gross income, operational profit, and benefit-cost ratio). Data suggest productive and economic variations among tested planting configurations, as an example higher productivity (31.5 t ha -1 ) and positive benefit-cost ratio (2.51) when using 1.0 m between rows and 0.4 m between plants for the conditions tested. These results point out the prospect to select better crop management practices for yacon, cutting costs, and increasing yield. Another key find was yacon's capacity to overcome intense drought and temperature stress, not previously documented for this crop. Therefore, yacon is a new crop with potential to boost farming income through crop diversification.
