Assessment of yield and water productivity of clementine trees under surface and subsurface drip irrigation

2018

Abstract Irrigation systems aimed to optimize water use efficiency in agriculture have become essential due to the increasing water limitations that agriculture is currently facing. Assessment of crop responses to different irrigation systems and strategies are therefore encouraged to find the most efficient options for each specific case. The main objective of this study was to assess the performance of a citrus crop under a surface (SI) and subsurface drip irrigation (SSI) with 7 (SI7, SSI7) or 14 emitters (SI14, SSI14) per plant, as well as a third SS treatment (SSIA), identical to SSI7 but equipped with and additional drip line buried between the tree rows. Evaluations were made in term…

STUDY ON ISOLATED MICROSPORE CULTURE IN CITRUS SINENSIS L. OSBECK CV. MORO, A BLOOD ORANGE CULTIVAR

2014

In vitro tissue culture represents a useful support for the advancement of Citrus breeding and propagation. Haploidy technology, that is the single-step development of complete homozygous genotypes from heterozygous parents through gametic embryogenesis, has already a huge impact on many relevant crops, representing an integral part in their breeding programmes (Germanà 2011a; 2011b). In order to increase the number of genotypes responding to gametic embryogenesis, in vitro isolated microspore culture of Citrus sinensis L. Osbeck cv. Moro, has been carried out, investigating the influence of the culture medium composition, and, particularly, of the plant growth regulator types and concentra…

Utilizzo di traccianti geochimici nella Limonicoltura Siciliana.

2018

Nell’ultimo decennio i consumatori hanno sviluppato un interesse crescente per la tracciabilità dei prodotti agroalimentari in particolare in relazione all’origine geografica. La conoscenza di una possibile relazione chimica tra suolo e prodotti agroalimentari è importante per valutare la provenienza e autenticità dei prodotti. Tutto ciò va a favore del consumatore e si traduce in maggiore sicurezza e qualità dell’alimento. La coltivazione del Limone (Citrus Limon (L.) Osbeck) è una delle più importanti colture al mondo e l'individuazione di potenziali frodi potrebbe essere migliorata studiando la sua composizione chimica che lo lega all’area di origine. Questo studio ha utilizzato le terre…

Participation of Dr. Petropoulos has been funded by the ENViSIoN-EO Marie Skłodowska-Curie grant (grant No 752094), part of the European Union’s Horizon 2020 research and innovation programme. Part of the present collaborative work was also materialised in the framework of a short Term Scientific Mission (STSM) of the HARMONIOUS Cost Action which financially supported Dr Petropoulos’ visit between 4 to 15 February 2020 to the Department of Engineering of the University of Palermo, Italy. Η συμμετοχή του Δρ. Πετρόπουλου χρηματοδοτήθηκε από το πρόγραμμα της Ευρωπαϊκής Ένωσης για Έρευνα και Καινοτομία «Oρίζοντας 2020», δράση Marie Sklodowska - Curie , έργο ENViSIoN-EO (αριθ. 752094).

Population dynamics and specific composition of phytoseiid mites (Parasitiformes, Phytoseiidae) associated with lemon trees in three differently mana…

2006

Surveys of phytoseiid mites were carried out in three lemon orchards in Sicily. The three orchards had different farm management and different environmental conditions: A) traditionally farm managed; B) organic farm managed; C) in state of neglect. The aim was to determine the specific composition of the above different types of orchards and to compare their population dynamics in order to obtain information on the influence of the different agricultural practices on the phytoseiid fauna. After two years of weekly samplings it can be assessed that no substancial differences were found in the phytoseiid specific composition among the three types of orchards. On the other hand, differences, s…

Verifica dell’applicabilità del metodo irriguo sub-superficiale su colture agrumicole e ottimizzazione dell’uso della risorsa idrica

2020

Gli impianti di subirrigazione (SDI), in relazione alla posizione interrata dei gocciolatori permettono la riduzione dei consumi irrigui, garantendo la possibilità di utilizzo di risorse altrimenti non utilizzabili. Tuttavia, i costi di investimento iniziali risultano maggiori di quelli relativi ai tradizionali impianti di microirrigazione e pertanto, diventano economicamente vantaggiosi, se l'efficienza del sistema viene garantita per periodi di almeno 15-20 anni. La SDI, inoltre, permette di ottenere valori elevati di efficienza d’uso dell’acqua, spesso superiori al 90%, se associata ad un monitoraggio continuo dello stato idrico del suolo e della pianta e ad una corretta stima delle esig…
