Measurements of crop evapotranspiration (ETC) and crop coefficients (kC)incactus have not yet been adjusted for the phenological stage using conserva-tion practices (i.e. mulching). In this study, soil water dynamics, ETCandkCwere measured in the forage cactus under cultivation systems with (WM) andwithout (NM) the use of mulch in the semi-arid region of Brazil.Opuntiastrictawas subjected to irrigation depths based on a percentage of the referenceevapotranspiration (ET0) (rainfed, 25, 50, 75 and 100%) and to two systems ofcultivation: WM and NM. Over time, the phenophases (?Ph) were established;the soil water balance components were calculated and the crop yield wasevaluated at harvest. The use of 8.2 Mg ha1mulch led to almost no reducedwater consumption by the crop when compared to the NM system; however,the mulch did maximize yield, at 839C day, when irrigated with 50% ET0. ThekCvalue was higher under the WM system, with the differences decreasingthroughout the cycle (?PhI, 36%;?PhII, 27%;?PhIII, 23%;?PhIV-HT, 17%; and?PhIV-RF, 14%). Therefore, the use of mulch in cultivating the cactus opti-mized forage production in less time and significantly increased the water useefficiency of the crop |

Título: |
The continuous timber production over cutting cycles in the Brazilian Amazon depends on volumes of species not harvested in previous cuts. |

Can heavily logged Amazonian dense forests produce commercial timber for a second harvest under a 25?35-year cutting cycle? To address this question, we evaluated the forest capacity to recover the volume extracted 32 years after heavy logging (90 m3 ha?1) in a 144-ha research area located in the Tapajós National Forest, Brazil (03°18?31? to 03°19?21? S; 54°56?28? to 54°56?15? W). Abundance (number of trees ha?1), basal area (m2 ha?1) and volume (m3 ha?1) were assessed in two censuses, one year before logging (1981) and 32 years after logging (2014) to evaluate the status of the timber stock. Canopy openings caused by logging and silvicultural treatments increased sunlight in the forest and boosted the growth of trees 5?45 cm in DBH. Light-demanding species accounted for most of the increase in density and timber volume in the study area after logging. Our findings indicated that 32 years after the first cut, the forest was not able to replace the volume extracted. Considering the present Brazilian forest management regulations, which allow a logging intensity of 30 m3 ha?1 in a 35-year cutting cycle, this volume could only be harvested if new species not logged in the first cut were included in the new species logging list. |
