Trifolium Michelianum

Two cultivars of balansa clover (Trifolium michelianum Savi.) were sown on eight occasions from 14 October 2005 to 5 February 2007 in Canterbury, New Zealand, which gave a range of photoperiod at emergence between 8.6 and 15.7 h. The duration from emergence to flowering was related to the length and direction of change in photoperiod at the time of emergence. Thermal time (Tt) from emergence to flowering was constant at ~620 degree-days for ‘Bolta’ and ~365 degree-days for ‘Frontier’ balansa clover plants, provided they emerged into increasing photoperiods. For plants that emerged into decreasing photoperiods, Tt from emergence to flowering decreased from ~1500 to ~630 degree-days for ‘Bolta’ but was constant at ~690 degree-days for ‘Frontier’. Models are presented to predict the Tt requirement from emergence to flowering for ‘Bolta’, ‘Frontier’ and, based on reanalysed data, CPI45856 balansa clovers in relation to daylength at emergence. These results are discussed in relation to farm sowing and management practices.

The Impact

Investigation of land-use and management changes at regional scales require the linkage of farm-system models with land-resource information, which for pastoral systems includes forage supply. The New Zealand Land Resource Inventory (NZLRI) and associated Land Use Capability (LUC) database include estimates of the potential stock-carrying capacity across the country, which can be used to derive estimates of average annual pasture yields. Farm system models and decision support tools, however, require information on the seasonal patterns of pasture growth. To generate such pasture growth curves (PGCs), the Agricultural Production Systems Simulator (APSIM) was used, with generic soil profiles based on descriptions of LUC classes, to generate PGCs for three regions of New Zealand. Simulated annual pasture yields were similar to the estimates of annual potential pasture yield in the NZLRI spatial database, and they provided information on inter-annual variability. Simulated PGCs generally agreed well with measured long-term patterns of seasonal pasture growth. The approach can be used to obtain spatially discrete estimates of seasonal pasture growth patterns across New Zealand for use in farm system models and for assessing the impact of management practices and climate change on the regional sustainability.

Protected Cultivation

The growing of consumer market demands introduction of new species of flowers and cultivars primarily for production under protected cultivation. The zinnia by the quickness of production can be regarded as an alternative, however demand studies by the lack of information in the literature. We evaluated the duration of different periods, the base temperature and thermal accumulation, expressed as degree-days for the potted zinnia ‘Profusion Cherry’, conducted under protected cultivation for different phenological subperiods. The test was conducted in a greenhouse covered with plastic and closed laterally with shading-net and the duration of subperiods were made to twenty times after sowing. The base temperature was determined by relative development and values-based temperature and thermal time in degree-days (DD). The results for the different phases were, respectively: first open flower-planting: 4.1 °C and GD 838, first open flower - 50% of flowers open: 3.0 °C and 184 GD and 50% of flowers open - senescence: 6.9 °C and 238 GD.

Cow Welfare

Pasture-based dairying in New Zealand and Australia has come under increasing animal welfare scrutiny as a result of changing public expectations for farm animal management. Concurrently, efficiency-driven changes in dairy management practices and a broadening of the feedbase beyond traditionally grazed pasture have resulted in increased intensification and stocking density within the dairy industries. This intensification has included a higher proportion of grain concentrates in the diet (particularly in Australia), and the greater management of cows off pasture and even in housing (particularly in New Zealand). Research to assess the animal welfare implications of these changes and to recommend good practice management has concentrated on issues of cow environments and cow feeding, including body condition. Research has shown that cows may be managed for a few hours per day on concrete surfaces without compromising their lying behaviour and other indicators of welfare, but that longer periods off pasture require the provision of a well drained and comfortable lying surface. Other research has defined the extremes of hot and cold/wet conditions beyond which cows benefit from provision of adequate shade and shelter. Research on cow body condition has indicated that welfare responses are aligned with measures of health and productivity in supporting the need to maintain a minimum body condition before calving and during the subsequent weight loss period of early lactation. Continued research, extension and industry adoption will enable dairy producers to address community expectations as they continue to change their farming practices.

Starting Point

Purpose Measurement practices have long been considered vital for informing the management of performance in organisations. Their application to local governments is a more recent, yet multi-decade phenomenon facilitated by New Public Management trends. This paper aims to review the landscape of publications that discuss performance measurement (PM) practices in Australian and New Zealand local government contexts and identify implications for future research. Design/methodology/approach A systematic review methodology was used to identify a shortlist of publications. Next, a rating-based researcher appraisal process was applied. Multiple iterations of search and appraisal were conducted to form the basis for inductive thematic analysis and synthesis. Findings Analysing 65 PM publications, two interrelated themes, namely, discourses of performance as efficiency, accountability or strategic growth and change were identified, which influence the adoption of local PM tools and frameworks. As demands for strategic growth and more complex service delivery increase, strategic and localised adaptation of PMs may be required to integrate learning and communicative competencies with technical and operational capabilities. Research limitations/implications The systematic review methodology has been applied to address some of the limitations of publication and reporting biases in literature. This research provides a starting point for future investigations and broadening of discourse in local government contexts. Originality/value This paper represents the first systematic review of 1995–2020 publications on performance management practices used by local governments in Australia and New Zealand.

Management Capability

This chapter explores the management strategies adopted by manufacturing firms operating in high versus low cost economies and investigates the reasons for differences in the management practice choices. The study reported in this chapter identifies a subset of countries that have either high or low labour costs, with USA, Sweden, and Japan being high, and India, China, and Brazil being low labour cost economies. The high labour cost manufacturing firms are found to have better management practices. In this chapter, the authors find that Australia and New Zealand manufacturing firms face relatively high labour cost but lag behind world best practice in management performance. The chapter concludes by highlighting the need for improvement in management capability for Australian and New Zealand manufacturing firms if they are to experience a reinvigoration of productivity, competitiveness, and long-term growth.

AbstractVessel biofouling is a significant pathway for the introduction of nonindigenous marine species (NIMS). New Zealand is the first nation to regulate the vessel biofouling pathway, with controls scheduled to come into force in May 2018. The Craft Risk Management Standard (CRMS): Biofouling on Vessels Arriving to New Zealand specifies the hull fouling thresholds that vessels must meet; and here, we present the evidence-based decisions that underpin these thresholds.Under the CRMS, a vessel must arrive in New Zealand with a “clean hull,” the thresholds for which are governed by the intended duration of a vessel's stay in New Zealand. For example, long-stay (≥21 days) vessels must meet a more stringent standard of hull cleanliness due to the increased likelihood of release and establishment of NIMS. While setting a clean hull threshold at “slime layer only” can be tractable when vessels operate within the specifications of antifouling coatings, incidental amounts of macrofouling can establish even under the best management practices. Because of such instances, the thresholds within the CRMS were designed to allow for the presence of some macrofouling species, albeit with restrictions to minimize biosecurity risk. These thresholds are intended to limit species richness and to prevent successful reproduction and settlement of the allowed taxonomic groups while considering the practicality and feasibility of implementation.The difficulties of managing biofouling on different areas of the hull are acknowledged within these thresholds. For example, a greater tolerance of macrofouling has been allowed for niche areas due to the difficulties in preventing biofouling on these areas.

Soil Temperatures

The Transylvanian Plain, Romania is an important region for agronomic productivity. However, limited soils data and adoption of best management practices hinder land productivity. Soil temperatures of the Transylvanian Plain were evaluated using a set of twenty datalogging stations positioned throughout the plain. Soil temperatures were monitored at the surface and at 10, 30, and 50 cm depths, and soil moisture was monitored at 10 cm. Preliminary results indicate that most soils of the Transylvanian Plain will have a mesic temperature regime. However, differences in seasonal warming and cooling trends across the plain were noted. These have important implications for planting recommendations. Growing degree days (GDDs) are preferred over maturity ratings, because they can account for temperature anomalies. The crop being considered for this study was corn. The base temperature (BT) was set at 10oC, and the upper threshold was 30oC. Two methods were used to calculate GDDs; 1) minimum and maximum daily temperatures, and 2) 24 h of averaged temperature data. Growing degree days were run from 110-199 day of year (DOY) to represent approximate planting date to tasseling. The DOY that 694 accumulated growing degree days (AGDDs) was reached at each site was then analyzed to identify differences across the TP. Three sites failed to reach 694 AGDDs by DOY 199, and were excluded from comparisons to other results. Averaged values were used to create spline interpolation maps with ArcMap 9.2 (ESRI, Redlands, CA, USA). The southeastern portion of the TP was found to tassel a month earlier assuming a planting date of 109 DOY. Four DeKalb® corn hybrids were then selected based on GDDs to tasseling, drydown, drought tolerance, and insect resistance. With a better understanding of the GDD trends across the TP, more effective planting and harvesting could be accomplished by Romanian farmers to maximize agronomic production.
