Evaluation of leaf carbon isotopes and functional traits in avocado reveals water-use efficient cultivars

Authors: Acosta-Rangel, A.; Ávila-Lovera, E.; De Guzman, M.; Torres, L.; Haro, R.; Arpaia, M.L.; Focht, E.; Santiago, L.

Plant water-use efficiency (WUE) describes the ratio of carbon gain to water loss during photosynthesis. It has been shown that WUE varies among crop genotypes, and crops with high WUE can increase agricultural production in the face of finite water supply. We used measures of leaf carbon isotopic composition to compare WUE among 24 cultivars of Persea americana Mill (avocado) to determine genotypic variability in WUE, identify potentially efficient cultivars, and to better understand how breeding

Soil erosion, runoff and nutrient losses in an avocado (Persea americana Mill) hillside orchard under different groundcover management systems

Authors: Atucha, A.; Merwin, i.; Brown, M.; Gardiazabal, F.; Mena, F.; Adriazola, C.; Lehmann, J.

Assess the influence of different groundcover management systems on erosion and runoff processes associated with extremely steep hillside avocado (Persea americana Mill) orchards, in a Mediterranean climate with high rainfall variability. We compared several groundcover management systems at a steep hillside avocado planting in a three-year study: 1) Bare soil (BS), pre- and post-emergence herbicides; 2) Vegetation strip (VS), post-emergence herbicide applied in a 1-m wide strip on the tree row plus

Environmental evaluation of high-value agricultural produce with diverse water sources: case study from Southern California

Authors: Bell, E.; Stokes-Draut, J.; Horvath, A.

Meeting agricultural demand in the face of a changing climate will be one of the major challenges of the 21st century. California is the single largest agricultural producer in the United States but is prone to extreme hydrologic events, including multi-year droughts. Ventura County is one of California's most productive growing regions but faces water shortages and deteriorating water quality. The future of California's agriculture is dependent on our ability to identify and implement alternative

Energy balance and greenhouse gas emissions in organic and conventional avocado orchards in Mexico

Authors: Astier, M.; Merlín-Uribe, Y.; Villamil-Echeverri, L.; Garciarreal, A.; Gavito, M.; Masera, O.

There is a worldwide growing awareness of the negative impacts of the increasing fossil fuel reliance and greenhouse gas (GHG) emissions from agriculture, in particular for intensive crop systems. We analyze the energy balances and greenhouse gas emissions from export-oriented avocado orchards in Mexico. Avocado is a very important export crop and one of the main drivers of land-use change in the country. We compared 12 avocado orchards under organic and conventional management during two production

Evaluation of aerial and root plant growth behavior, water and nutrient use efficiency and carbohydrate dynamics for Hass avocado grown in a soilless and protected growing system

Authors: Beyer, C.; Cuneo, I.; Alvaro, J.; Pedreschi, R.

Avocado production is nowadays questioned worldwide and at risk due to climate change and the high water footprint of this crop. Thus, there is need for the development or adoption of new strategies such as alternative production systems. In this study, Hass avocado plants grafted on two rootstocks (Mexicola -seed propagated and Dusa® - vegetative-propagated and referred as clonal) were grown in a greenhouse and substrate (coir growth container, 55 L of volume and 500 × 480 mm, H X W) culture

Blue and Green Water Footprint of Agro-Industrial Avocado Production in Central Mexico

Authors: Gómez-Tagle, A.; Fuerte-Velázquez, D.; Barajas-Alcalá, A.; Quiroz-Rivera, F.; Alarcón-Chaires, P.; Guerrero-García-Rojas, H.

Mexico is the world-leading avocado producer. The municipality of Uruapan in the Avocado Belt region in Central Mexico produces 153,000 tons a year, nearly 6.4% of Mexico’s total volume. We performed a green and blue water footprint (WF) analysis between 2012 to 2017 in this municipality, and compared the estimated WF volumes with water concessions for agriculture. Mean annual rainfall was 1757.0 mm in the study period, mean effective rainfall 877.2 mm, mean crop evapotranspiration 933.1 mm, and
