Market Performance of Avocado Fruits among Smallholder Farmers in Southern Highlands of Tanzania
This study was designed to determine factors that influence market performance of avocado fruits among smallholder farmers in Mbeya and Songwe regions. A cross section research design entailing 209 farmers from five (5) districts of two (2) regions and 15 key informants; 5 local service providers (LSP), 5 traders/brokers and 5 district extension officers (DEO) were involved in the study. Random selection procedures were used to select avocado producers and purposive selection procedures were used
Foresight to 2035 in cold climate fruit trees: scenario alignment, Delphi method, and complement with Python libraries
"Cold-climate fruit trees, such as avocado, blackberry, curuba, lulo, and goldenberry, are economically and socially significant in Andean countries. This study employs foresight methodologies to support strategic planning, prioritize innovations, and reduce uncertainty in decision-making within this agro-industrial chain. Scenario analysis and the Delphi method were applied, analyzing 34 variables using MICMAC, identifying nine as key. Three future objectives were formulated and assessed with key
Avocado drought stress alleviation through different soil amendments
"
Under the uncertain scenario of water availability for irrigation, plants are often exposed to drought periods, which can negatively impact their vegetative growth and yield potential. To address this issue, various soil amendments including inorganic, organic, and biological treatments, have been investigated as solutions for mitigating water stress. However, comparative studies of different amendments are lacking. The aim of this study was to assess the efficacy of various soil amendments

Accessible drone image processing for sustainable resource management of 3D tree-like crops using unsupervised algorithms
This study presents a novel AI-driven solution designed to enhance sustainable resource management and increase accessibility for farmers through visualized and digitalized tree information. The proposed methodology includes optimizing drone mapping for effective data coverage, capturing high-resolution imagery, and generating a 3D Point Cloud, with a particular emphasis on the integration of Weighted K-means, Density-based spatial clustering of applications with noise (DBSCAN), and cluster separation
Comparative Analysis of Water Stress Regimes in Avocado Plants during the Early Development Stage
The avocado cv. Hass requires a suitable rootstock for optimal development under water stress. This study evaluated the performance of two avocado rootstocks (ANRR88 and ANGI52) grafted onto cv. Hass under four water stress conditions, 50% and 25% deficit, and 50% and 25% excess during the nursery stage. Plant height, leaf area (LA), dry matter (DM), and Carbon (OC) content in the roots, stems, and leaves were measured. Root traits were evaluated using digital imaging, and three vegetation
Outcrossing Rate and Fruit Yield of Hass Avocado Trees Decline at Increasing Distance from a Polliniser Cultivar
Optimal fruit production from many tree crops relies on the transfer of cross-pollen between trees of different cultivars rather than the transfer of self-pollen between trees of the same cultivar. However, many orchards are established with wide blocks of single cultivars, which can result in high percentages of self-fertilised fruit and sub-optimal yield and quality. We aimed to determine whether outcrossing rates and yield of Hass avocado fruit decline with increasing distance from polliniser
