ABSTRACTAgroforestry parklands are a common land-use in Ethiopia and many parts of the tropics. These systems play an important role in climate change mitigation and adaptation, through carbon (C) sequestration. However, C sequestration in both tree biomass and soil has not been extensively studied for parklands of the Central Rift Valley (CRV), Ethiopia. Therefore, here we sampled a small number of F. albida trees and soil from the Adulala watershed, CRV, to provide a preliminary estimate of th...

A number of agroforestry models have been developed to simulate growth outcomes based on the interactions between components of agroforestry systems. A major component of this interaction is the impact of shade from trees on crop growth and yield. Capability in the agricultural production systems simulator (APSIM) model to simulate the impacts of shading on crop performance could be particularly useful, as the model is already widely used to simulate agricultural crop production. To quantify and...

ABSTRACTPsychological distress is prevalent in doctoral degree training and affects students' completion time. It is crucial to monitor the amount of distress experienced and understand the causes for it to inform the type of support most needed. This mixed method study explored challenges related to candidature, self-reported progress and measures of perceived and actual psychological distress with a convenience sample of 81 doctoral candidates in an Australian university. Using validated surve...

Unmanned aircraft system (UAS) in combination with multispectral sensors stimulate the utilisation of site-specific technologies to manage crop production according to intrafield variability. Crop monitoring requires accurate calibration. However, radiometric calibration methods in practice are difficult to implement for UAS remote sensing as every single image requires correction due to smaller field of view and changes in light. Therefore, this paper proposes an easy radiometric calibration pr...

Abstract Biological farming practices using bio-inoculants and renewable organic supplements are being increasingly adopted by primary producers although little is known about their benefits compared to conventional fertiliser practices. Two trials were conducted on sunflower ( Helianthus annuus L., ‘Dwarf Sunsation’) to compare the influence and interaction of arbuscular mycorrhizal fungi (AMF) inoculation with organic and conventional synthetic fertilisers on plant growth and development. Comm...

Faidherbia albida is an important tree species in the parkland agroforestry system of the Rift Valley region, central and south-eastern Ethiopia. Positive effects of F. albida on crop production are widely recognised. However, the effects of tree pruning, zone and fertiliser interactions on crop growth have not been addressed in earlier studies. A field experiment containing three levels of tree pruning (100% pruned, 50% pruned, and unpruned) as main plots, and application of recommended rates o...

AbstractObjectives: To examine the impact of guided mindfulness practice on psychological distress and psychological capital (hope, optimism, resilience, and efficacy) in doctoral candidates. Participants: Recruitment of a convenience sample of doctoral candidates occurred in July 2015 and participants were randomly allocated to the control or intervention group (38 and 34 participants completed the trial, respectively). Methods: A single-blinded, randomized controlled trial with intention-to-tr...

Abstract Improved prediction of poppy capsule volume is essential for optimal management of poppy crop. In order to estimate poppy capsule volume accurately using remotely sensed imagery, the selection of most appropriate models and predictor variables is essential. Multiple spectral indices with random forest (RF) regression were tested to estimate poppy capsule volume using an Unmanned Aircraft System (UAS). Data were collected from field-based physical measurements, in-field spectral measurem...

Defoliation may initiate physiological recovery and chemical defence mechanisms that allow a plant to improve fitness after damage. Such responses may result in changes in plant resource allocation that influence growth and foliar chemistry. In this study, we investigated the nature and stability of the defoliation response of juvenile plants from three divergent populations of Eucalyptus globulus Labill. A partial defoliation treatment that removed all upper crown leaves and the apical buds was...

Non-aerated compost teas (NCTs) are water extracts of composted organic materials and are used to suppress soil borne and foliar disease in many pathosystems. Greenhouse trials were used to test the effectiveness of NCTs to suppress potato bacterial wilt caused by Ralstonia solanacearum on plants grown in soils inoculated with a virulent isolate of the pathogen (biovar II). NCTs prepared from matured compost sources: agricultural waste (AWCT), vermicompost (VCT) and solid municipal waste (SMWCT)...
