Losses in the production of avocado (Persea americana (Mill.)) are incurred due to Phytophthora root rot (PRR), a disease feeder roots that results tree-dieback and eventual tree death. Avocado is also flood-sensitive species flooding exacerbates effects PRR. The industry relies on use rootstocks tolerant PRR minimise losses. present study compared gas exchange chlorophyll fluorescence responses rootstock plants 'Dusa™', current South African standard, with 'Duke 7', selections R0.12 R0.06...
Inaccurate crop coefficients are major contributing sources of uncertainty that lead to inefficient use limited available water resources. Understanding the need improve efficiency in South Africa's fruit industry, this study evaluated method deriving developed by Allen and Pereira (2009) over a variety irrigated tree crops. Detailed data transpiration, evapotranspiration weather variables measured using heat ratio method, eddy covariance automatic stations, were collected from research...
Wheat straw has generally been used as the main substrate for cultivating oyster mushrooms (Pleurotus ostreatus); however, in South Africa it is becoming expensive small-scale farmers to utilise. Therefore, objective of study was investigate use alternative, but suitable substrates planting mushrooms. (control), wood chips and thatch grass, selected on account their year-round availability low cost, were tested with two drainage treatments (drained or not drained) replicated four times....
Abstract The current rapid increase in ambient carbon dioxide concentration ([CO 2 ]) and global temperatures have major impacts on the growth yield of crops. Potato is classified as a heat-sensitive temperate crop its are expected to be negatively affected by rising temperatures, but it also respond positively increasing [CO ]. In this study, we investigated physiological, growth, responses two potato cultivars elevated temperature (eT) possible role ] (e[CO counteracting negative effects...
Rosellinia necatrix is the causal agent of white root rot (WRR), a fatal disease affecting many woody plants, including avocado (Persea americana). As with other diseases, an integrated approach required to control WRR. No fully effective methods are available, and no chemical or biological agents against R. have been registered for use on in South Africa. Fluazinam has shown promising results greenhouse field countries, Spain. The current study aimed investigate potential fumigant,...
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...

Subtropical fruit crops form an important part of the industry in many countries.Many these are grown semi-arid regions or subtropical where rainfall is seasonal and as a result vast majority perennial, evergreen orchards under irrigation.This represents significant irrigation requirement with more emphasis being placed on conservation water orchard profitability, it becoming increasingly to accurately estimate use schedule accordingly.The FAO-56 procedure simple, convenient reproducible...
The accurate estimation of evapotranspiration (ET) orchard crops is critical for judicious irrigation water management and planning.However, it impossible to measure ET under all possible combinations climate practices, which necessitates the use models.Although empirical models are more likely be adopted by consultants growers, due easier parameterization requirements fewer, easily measured input parameters, they may not always transferable across a wide range conditions.As result these...

Thermal remote sensing has been introduced as a robust technology for monitoring water status in plants, real-time and non-destructive approach, under variety of environments. Canopy temperature is key indicator stress extensively used the determination crops. A previous planting date study conducted South Africa revealed large decline yields between December January regardless cultivar or location. This aims to monitor crop plant health across four monthly dates weekly January. The trial...
