In this study we present the effects of different fruit and timber tree species in a multi-strata agroforestry system on inorganic and organic P pools of a Xanthic Ferralsol. The soils were in readily available P, stressing the importance of fertilization and soil management practices for nutrient replenishment. The investigated agroforestry system consisted of cupuacu, pupunha (peach palm), castanha-do-Para (Brazil nut), urucu (annatto) and pueraria. Under canopies of the same tree species a high variation of the P contents were found especially under pupunha. The total P values of the soils in the pupuna row differed from 194 mg g-1 to 516 mg g-1. The sites under the unfertilized legume cover crop pueraria had two times higher soil P contents than those under adjacent unfertilized natural vegetation. It can be assumed that pueraria uses the P from the fertilized area under the tree crops and enrich the soil between the trees. |

Climate change is undoubtedly altering the atmosphere, occasioning extreme temperatures that can cause weather calamities such as droughts and floods. Among the major constraints limiting crop production, drought is one of the most important.
Sugarcane (Saccharum spp. hybrid) is considered an important economic crop not only for sugar production, but also for ethanol generation, serving as an expandable green alternative to crude oil use. To take advantage of the use of sugarcane as renewable
source for bioethanol production, it is important to increase its productivity without increasing land use, which includes cultivation under hostile conditions, such as water?limited environments. Previously, we demonstrated that stress?inducible
overexpression of the transcription factor AtDREB2A CA conferred drought tolerance in sugarcane subjected to water deficit under greenhouse conditions. In the present work, the AtDREB2A CA transgenic sugarcane lines were evaluated in the field in two representative seasonally dry regions of Brazil. The results demonstrated that the AtDREB2A CA sugarcane lines presented higher yield and productivity when compared to non?transformed plants under drought, representing a suitable strategy for the development of new drought?tolerant cultivars. |
