Diversity of Culturable Endophytic Fungi Associated with Avocado Orchards Under Organic and Conventional Management
Endophytic fungi constitute a great resource for the implementation of sustainable agricultural practices. However, their diversity may be altered by agrochemicals used in conventionally managed agrosystems. Here we explored the culturable diversity of endophytic fungi associated with avocado (Persea americana Mill.) in conventional and organic orchards from three counties of the world’s leading productive region. In total, 529 endophytic fungal isolates were obtained from branches and roots of
Sustainable Irrigation Strategies for Enhancing Hass Avocado Yield in Arid Region of Tacna, Peru
Hass avocado production in the Tacna region of Peru faces challenges related to irrigation efficiency and water availability. Efficient water management is essential for improving tree growth, fruit yield, and economic sustainability. This study aims to evaluate the relationship between irrigation efficiency, soil moisture levels, and avocado productivity to identify key factors influencing sustainable production. A comparative analysis approach was used to assess soil moisture, irrigation efficiency,
Climatic and soil impacts on avocado (Persea americana L.) yield and quality in Southern Ethiopia: a comparative study
This study investigates the impact of climatic variables and soil characteristics on the fruit yield and quality of avocado (Persea americana L.) cultivars in Southern Ethiopia, focusing on six prominent varieties: Hass, Fuerte, Ettinger, Bacon, Pinkerton, and Nabal. Using data from Sidama and Wolaita regions, and examined how factors such as temperature, precipitation, soil pH, and organic matter influence avocado production. The analysis revealed significant regional differences, with Sidama consistently
Does green stem photosynthesis affect plant drought tolerance and recovery in avocado?
Woody plants with green stems may have advantages over non-green-stemmed plants in that extra photosynthetic carbon gain has the potential to improve plant drought tolerance and aid drought recovery. However, most studies relating to green stem photosynthesis and drought tolerance have been conducted on non-horticultural plants under natural growing conditions. We investigated whether avocado green stem photosynthesis enhances drought tolerance and recovery. We applied light exclusion and drought
Short-term spectral indication of the salinity effects on avocado rootstocks growth caused with ground and regenerated wastewater irrigation
An avocado rootstocks were grown in a pot experiment with lysimeters to evaluate the effect of three irrigation options: groundwater (GW), regenerated wastewater (RWW), and a 1:1 mixture of both (GW/RWW-1:1). Plant water and salt stress assessment was carried out using leaf non-destructive and destructive methods during the fifth and sixth months of the experiment. The avocado leaf blade area decreased by the end of observations in the GW/RWW-1:1 and RWW treatments by 1.2 and 1.5 times compared to
Impacts of Converting Native Grassland into Arable Land and an Avocado Orchard on Soil Hydraulic Properties at an Experimental Farm in South Africa
The main objective of this study was to evaluate the changes in soil water retention curve (WRC) and pore size distribution in the 0–10, 10–20, and 20–30 cm layers following grassland conversion into arable land and an avocado orchard. Undisturbed soil cores were sampled using cylindrical metal cores to determine WRCs. The RETC program was used to fit the van Genuchten equation to the measured water retention data. The maximum equivalent radius (r) of soil pores retaining water at various matric
