Bitter cassava is an important food crop that was domesticated in Amazonia. Although it is exclusively propagated by stem cuttings, cassava retained its ability of sexual reproduction. The occurrence and incorporation of sexual plants into the stock of clonal varieties contributes to the high genetic diversity observed within the crop. Despite being well adapted to nutrient deprived soils of Amazonia, ethnobotanical observations showed that communities of smallholder farmers along the middle Madeira River, in Central Amazonia, also cultivate cassava in the highly fertile soils of the floodplains and Amazonian dark earths (ADE). These farmers grow different sets of varieties in each soil type, which may also contribute to the maintenance of high levels of genetic diversity within the crop. We evaluated with 10 nuclear microsatellite markers the genetic diversity within and among some of the most commonly cultivated bitter cassava varieties grown on ADE, floodplain and Oxisols soils in the middle Madeira region. High levels of genetic diversity within varieties were observed (HO ranging from 0.495 to 0.707, and HE ranging from 0.250 to 0.460). Additionally, varieties were generally highly differentiated from each other. Although high levels of genetic diversity were previously observed in studies carried out in regions of low soil fertility in other parts of Amazonia, we identified that management of different soil types is important to the maintenance of genetically distinct stocks of varieties, which also contributes to the maintenance of the genetic diversity within the crop.

The study has objective to calculate the green, blue and grey agricultural water footprint (WF) of ethanol and sugar produced from sugar cane, under subsurface fertigation production system, in Piauí State, Brazil. Sugar and ethanol production data in response to different irrigation levels (288, 492 and 675 mm), nitrogen fertigation (90, 113 and 160 kg ha-1 N ) and potassium (60 and 133 kg ha-1 of K2O) plus a control treatment (2,080 mm of rainfall, 75 kg N ha-1 and 75 kg ha-1 of K2O) were obtained from a trial under subsurface drip irrigation system, RB 867515 sugar cane variety, 1st ratoon, conducted in COMVAP - Sugar and Alcohol Inc., União county, Piauí State, Brazil. Under subsurface drip fertigation, the agricultural WF for sugar production ranged from 1,493 L kg-1 (1,175 L kg-1 - green water, 163 L kg-1 - blue water and 155 L kg-1 - grey water) to 1,172 L kg-1 (823 L kg-1 - green water, 267 L kg-1 - blue water and 83 L kg-1 - gray water). For ethanol production, the agricultural WF ranged from 2,081 L L-1 (1,638 L L-1 - green water, 227 L L-1 - blue water and 216 L L-1 - grey water) to 1,483 L L-1 (1,040 L L-1 - green water, 338 L L-1 - blue water and 105 L L-1 - grey water). Under non-irrigated condition, the agricultural WF for sugar production was 1,915 L kg-1 (1,763 L kg-1 - green water and 152 L kg-1 - grey water) and 2,658 L L-1 (2,448 L L-1 - water green and 211 L L-1 - grey water) for ethanol production. The agricultural WF for the ethanol production was superior to sugar production. Agricultural water footprint under fertigation was lower than that obtained under non-irrigated condition, and should be a recommended practice for increasing water productivity to sugar and ethanol production from sugar cane crop in the region evaluated.
