Tree responses to fertilizer management are complex and influenced by the interactions between environment, other organisms, combined genetics of composite trees. Increased consumer awareness environmental impact agriculture has stimulated research toward increasing nutrient-use efficiency, improving sustainability, maximizing quality. Here, we highlight recent advancements identify knowledge gaps in nutrient dynamics across soil–rhizosphere–tree continuum for fruit crops. Beneficial soil...
Objective: The aim was to investigate factors contributing food wastage by Stellenbosch University (SU) students in selected residences, and determine the attitudes practices of catering personnel impacting on waste a sustainable environment.Design: Cross-sectional, descriptive study.Setting: University, Western Cape.Subjects: Six foodservice managers, 63 517 participated study.Outcome measures: A weighed-food study conducted at seven residences during lunch supper three non-consecutive...
The Western Cape region of South Africa, a major producer deciduous fruit, has been identified as highly vulnerable to climate change. Climatic trends were analysed on monthly basis for 12 rural meteorological stations across the period 1967 2007. Significant warming found midto late-summer and end-winter spring daily minimum temperature (Tmin), mid-summer, autumn maximum (Tmax). Chill unit accumulation decreased significantly, particularly in autumn. Air temperatures are predicted increase...
ABSTRACT Pre-harvest foliar applications to increase fruit calcium (Ca) content and reduce bitter pit incidence, is a standard practice world wide. We re-evaluated the effectiveness of early season versus late nitrate (Ca(NO3)2) in 'Golden Delicious,' under present environmental conditions Western Cape, South Africa. Two periods efficient uptake external Ca were identified, viz., during cell division last few weeks before harvest. Foliar mid (from 40 d after full bloom) more effective...
An experiment that entailed the manipulation of irrigation was carried out to assess effect water stress on sunburn development in ‘Cripps’ Pink’ apples. Normal irrigation, half and no treatments were applied for 15 days starting 14 Mar. 2010 (Southern hemisphere). Stem potential, fruit surface temperature (FST), incidence, severity measured. Sunburn also categorized into browning, necrosis, or bleaching types. Fully exposed without prior symptoms tagged progressive assessments, whereas...
Abstract Honeybush ( Cyclopia ) species are endemic to the Fynbos Biome of Cape Floral Kingdom in South Africa. Traditionally, honeybush foliage is cut, fermented, and sun‐dried make an antioxidant‐rich herbal tea. Approximately 80% unsustainably harvested from wild. All commercial indicated on International Union for Conservation Nature Red List Threatened Species. Cultivation thus required ensure sufficient volumes tea produced. A major limitation cultivation poor rooting responses that...
SummaryOrchards displaying calcium (Ca) deficiency are a common phenomenon worldwide, despite the presence of sufficient Ca in soil and plant. A 3-year trial was conducted between 2007 – 2008 2009 2010 growing seasons to evaluate contributions foliar applications concentrations 'Braeburn' apple (Malus × domestica Borkh.) fruit. Ca(NO3)2 (Calflo; Yara Africa, Fourways North, South Africa) applied as six separate sprays until run-off. Applications were made at 1-week intervals approx. 21 70 d...
SummaryLosses of apple fruit due to sunburn damage under South African climatic conditions can reach up 40% per annum for specific cultivars in certain years. Various approaches reduce the incidence and severity resulted temporary effects but, at present, no single remedy is available provide a significant consistent reduction on commercial scale. 'Golden Delicious' trees that received both calcium (Ca) boron (B) as foliar applications weekly basis, when applied from approx. 21 – 70 d after...
ISHS VI International Symposium on Mineral Nutrition of Fruit Crops ASSESSMENT OF PRE-HARVEST PHYSIOLOGICAL INFILTRATION METHODS FOR PREDICTING COMMERCIAL BITTER PIT IN 'BRAEBURN' AND 'GOLDEN DELICIOUS'
Apple production for the export market is in South Africa entirely dependent on irrigation.In recent years, high performing orchards yielding up to 120 t of fruit ha -1 are becoming common a country where average yield between 60 and 80 .This raises important questions regarding sustainability exceptionally yields given limited availability water irrigation.Moreover, there also no accurate quantitative information published use by apple different age groups this compromises efficient...
The efficacy of ion absorption through the cuticle a leaf fruit has been related conditions whilst applying (i.e., environmental) and receiving surface exposure area covered, capacity absorption). influence product's physical chemical properties like point deliquescence should be taken under consideration while quantifying penetration. present study compares traditional recent calcium formulations (total 10) by evaluating penetration distribution on tomato fruits as well comparing plant...
