Optimal fruit production from many tree crops relies on the transfer of cross-pollen between trees different cultivars rather than self-pollen same cultivar. However, orchards are established with wide blocks single cultivars, which can result in high percentages self-fertilised and sub-optimal yield quality. We aimed to determine whether outcrossing rates Hass avocado decline increasing distance polliniser cultivar Shepard selfed smaller outcrossed fruit. Outcrossing declined 49% at six (40...
Imaging technologies are advancing rapidly in food processing systems to reduce waste. However, modelling techniques, sample sizes and dataset proportioning methods significantly affect the performance of models predicting quality variables. This study examined potential hyperspectral imaging predict peroxide values (PV), free fatty acid (FFA) levels concentrations, including oleic linoleic acid, two tree nuts, canarium macadamia. The effectiveness artificial neural network (ANN) regression...
ABSTRACT Climate change threatens long‐term soil health because of increased severity and frequency drought periods. Applying biochar to soils before a can increase non‐biochar carbon (C) water storage over the long term sustain crop yield. However, on‐farm benefit buried solid applied liquid at low rates remains uncertain. This study examined effects two novel biochar‐based amendments on C, The included reactive barrier (RB) made by layering wood‐based biochar, straw mulch cow manure into...
Tree nuts are a convenient and nutritious food source recently considerable attention has been placed on quality assessment to provide high improve consumer satisfaction. Moisture is critical parameter for tree nut routinely monitored throughout post-harvest processing. However, current direct methods assess moisture based using limited numbers of representative sub-sets destructive. This study aimed use hyperspectral imaging machine learning (ML) predict individual macadamia during...
Rapid assessment tools are required for monitoring crop nutrient status and managing fertiliser applications in real time. Hyperspectral imaging has emerged as a promising tool to manage nutrition. This study aimed determine the potential of hyperspectral predicting foliar concentrations avocado trees establish whether different sides leaves affects prediction accuracy. images (400–1000 nm) were taken both surfaces collected from Hass 0, 6, 10 28 weeks after peak anthesis. Partial least...
The six recommendations made by the Guidelines for Assessment and Instruction in Statistics Education (GAISE) committee were first communicated 2005 more formally 2010. In this article, 25 introductory statistics textbooks are examined to assess how well these have incorporated three GAISE most relevant implementation (statistical literacy thinking; use of real data; stress concepts over procedures). another recommendation (using technology) is described but not assessed. general, appear be...
Hyperspectral image (HSI) analysis has the potential to estimate organic compounds in plants and foods. Curcumin is an important compound used treat a range of medical conditions. Therefore, method rapidly determine rhizomes with high curcumin content on-farm would be significant advantage for farmers. varies within, between varieties but current chemical methods are expensive time consuming. This study compared three turmeric (Curcuma longa) examined laboratory-based HSI predict using...
Managing the nutritional status of strawberry plants is critical for optimizing yield. This study evaluated potential hyperspectral imaging (400-1,000 nm) to estimate nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) concentrations in leaves, flowers, unripe fruit, ripe fruit predict plant Partial least squares regression (PLSR) models were developed nutrient concentrations. The determination coefficient prediction (R2P) ratio performance deviation (RPD) used evaluate accuracy,...
Abstract Understanding root development in soil profiles of agroforestry systems is challenging. It uncertain to what extent the proximity cash crops, such as cocoa and coffee, shade trees reduces nutrient concentrations topsoil whether crops continue develop fine roots when they are planted close trees. We aimed investigate micro‐ macro‐nutrient profile understand architecture using a novel DNA metabarcoding approach an system where coffee were interplanted with tree, canarium. Soil samples...

Digital tools were embedded facilitate student engagement lieu face-to-face contact, including crosswords low-level statistical literacy,...
Abstract Stingless bees are increasingly in demand as pollinators agricultural crops within the tropics and subtropics. Hive splitting, where one strong managed hive is “split” into two independent daughter colonies, commonly used to increase numbers. However, how splitting impacts foraging behaviour or time taken for colony recover from has not previously been studied. We assessed impact of on Tetragonula carbonaria colonies. The number returning forager trips foraged proportions pollen,...
