Optimization of water resource management in crops using satellite technology and artificial intelligence techniques
This study aims to optimize water consumption in avocado crops through the application of satellite technology, machine learning algorithms, and precise climate data from the climate hazards group infrared precipitation with stations (CHIRPS) system. Crop classification in satellite images is conducted using the random forest algorithm, enabling detailed categorization of cultivated areas, urban land, soil, and vegetation, with a specific focus on avocados due to their high-water demand. Given its
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,
Influence of Deficit Irrigation and Absorbent Materials on “Hass” Avocado Cv.:B- Leaf Chemical Composition, Water Use Efficiency and Economical Returns
Avocado (Persea americana Mill.) is a globally important fruit crop, with the 'Hass' cultivar being the most widely cultivated. Water scarcity threatens the sustainability of avocado production in arid and semi-arid regions. During (2023–2024) field study was established to evaluate the effects of two soil absorbent materials biopolymer and zeolite applied at 500, 1000, and 1500 g/tree under three regulated deficit irrigation regimes (100%, 80%, and 70% of irrigation requirements, IR) on leaf chemical
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
Remote Sensing and Soil Moisture Sensors for Irrigation Management in Avocado Orchards: A Practical Approach for Water Stress Assessment in Remote Agricultural Areas
Water scarcity significantly challenges agricultural systems worldwide, especially in tropical areas such as the Dominican Republic. This study explores integrating satellite-based remote sensing technologies and field-based soil moisture sensors to assess water stress and optimize irrigation management in avocado orchards in Puerto Escondido, Dominican Republic. Using multispectral imagery from the Landsat 8 and 9 satellites, key vegetation indices (NDVI and SAVI) and NDWI, a water-related index
