Effect of deficit irrigation during oil synthesis period on carbohydrates content in olive hedgerows (cv. Arbequina)
(ISHS, 2016)During fruit oil synthesis and accumulation period, fruits are the main carbohydrate sink and water stress may modify the reserve availability for next season development. The objective of this study was to evaluate the ... -
Effect of irrigation and tree density on vegetative growth, oil yield and water use efficiency in young olive orchard under arid conditions in Mendoza, Argentina
(2015-11)We measured the effects of planting density (238, 317 and 476 trees ha−1), irrigation (fully irrigated control vs. deficit irrigation) and their interaction on the vegetative growth, yield and irrigation water use efficiency ... -
Effect of olive hedgerow orientation on vegetative growth, fruit characteristics and productivity
(2015-08-31)The effect of row orientation on oil production and fruit characteristics was studied, during years 3–6 after planting of the super-high density olive hedgerows (1923 tree/ha) planted at the same row spacing (4 m) in four ... -
Effect of regulated deficit irrigation during the vegetative growth period on shoot elongation and oil yield components in olive hedgerows (cv. Arbosana) pruned annually on alternate sides in San Juan, Argentina
(Springer, 2019-04)In super-intensive hedgerows, vegetative vigor must be controlled to allow access to harvesting machinery, particularly under Argentina conditions in which olive trees display excessive vigor. During shoot growth (spring–early ... -
Effect of row spacing on vegetative structure, fruit characteristics and oil productivity of N–S and E–W oriented olive hedgerows
(2015-09-22)The effect of row spacing on fruit characteristics and production was studied in two super-high density olive hedgerow orchards planted at three row spacings (5.0, 4.0 and 2.5 m) with the same intra-row tree spacing, one ... -
Effect of shading in different periods from flowering to maturity on the fatty acid and phenolic composition of olive oil (cv. Arbequina)
(2018-10)In olive there is insufficient information about how radiation changes throughout different growing periods affect oil quality. The present three-season study was conducted on an 'Arbequina' orchard. In addition to control ... -
Effects of pre-harvest deficit irrigation during the oil accumulation period on fruit characteristics, oil yield extraction, and oil quality in olive cv. Genovesa in an arid region of Argentina
(Elsevier, 2021-06)The effect of pre-harvest deficit irrigation was studied as a tool to reduce fruit moisture and evaluate its influence on fruit characteristics, oil yield extraction, and oil quality. Two regulated deficit irrigation ... -

Estudio taxonómico y ciclo biológico de Aceria oleae (Nalepa, 1900) (Acari: Eriophyidae), parásito de Olea europaea L. cv Arauco, en la provincia de La Rioja
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2015)El olivo (Olea europaea L.) llegó a la Argentina en 1565.La zona donde mejor se adaptó fue en Arauco (La Rioja) y de allí se propagó a la zona Andina y Central. Posteriormente se extendió hacia el Litoral, Norte y Sur del ... -
Estudios bioecológicos para actualizar conocimientos sobre cochinillas (Insecta: Hemiptera) presentes en olivares de Catamarca y La Rioja
(Facultad de Ciencias Agrarias y Forestales, Universidad Nacional de La Plata, 2012)Argentina es el país olivícola más importante del continente Americano, tanto en cantidad de plantas como producción anual obtenida, siendo una actividad asociada a la región oeste y noroeste del país. El olivo constituye ... -
Evaluation of olive flowering at low latitude sites in Argentina using a chilling requirement model
(2015)Olive production has expanded significantly from the Mediterranean Basin into the New World over the last two decades. In some cases, cultivars of European origin have been introduced at a large commercial scale with ... -
Fruit Characteristics and a Simple Estimate of Oil Content in Twenty-Six Olive Genotypes in Argentina
(Tarbiat Modares University, 2021)There are more than two thousand varieties of olives grown worldwide, most of them native to the Mediterranean Region. However, in Argentina, only a small number of olive varieties are cultivated. In Mendoza Province, there ... -
Fruit, mesocarp, and endocarp responses to crop load and to different estimates of source: sink ratio in olive (cv. Arauco) at final harvest
(2018-04-14)The annual fluctuations in olive crop load due to alternate bearing and other factors often lead to large differences in fruit size and oil content between years at harvest. A better understanding of how fruit parameters ... -
