Variability of Spring Barley Traits Essential for Organic Farming in Association Mapping Population
2012
Association mapping population consisting of 154 Latvian and foreign spring barley genotypes contrasting for traits that are important for organic agriculture was established with the aim to develop molecular markers useful in breeding for organic farming. The mapping population was genotyped at 3072 single-nucleotide polymorphism loci using Illumina GoldenGate platform to provide marker data for association mapping. Field trials in two organically and two conventionally managed locations are being carried out during three seasons. The following traits essential for organic farming were phenotyped: plant morphological traits ensuring competitive ability against weeds, grain yield in organic…
ASSESSMENT OF THE IMPACT OF VERMICOMPOST AND PEAT EXTRACTS ON NUTRIENT ACCUMULATION IN TUBERS AND POTATO YIELD
2018
Investigations on the potential beneficial effect of humic substances on crop plant cultivation under extremely diverse soil and climatic conditions is of global character, thereby knowledge obtained on the basis of local investigations are of great importance world-wide. The aim of the research was to evaluate the effect of different application methods (seed tuber treatment and foliar application) of commercially-produced peat and vermicompost extracts on nutrient uptake in tubers and yield of potato ( Solanum tuberosum L.) using field experiments in organic farming system with potato variety ‘Borodjanskij Rozovij’. The tested extracts from the organic products included: peat extract (K45…
Grano duro biologico: i consigli varietali.
2019
Nell’annata agraria 2018-19, per il 17° anno consecutivo, sono state effettuate prove collegiali di confronto tra varietà di frumento duro in coltura biologica, in collaborazione con diverse Istituzioni. Le prove sono state realizzate in 7 località, dislocate in 6 regioni del Centro-Sud (Sicilia, Sardegna, Puglia, Toscana e Marche), utilizzando uno schema sperimentale a blocchi randomizzati con 3 o 4 ripetizioni. In tutti i campi sono state messe a confronto le stesse 19 varietà, fornite non conciate dalle ditte sementiere.A livello produttivo le varietà Emilio Lepido, Iride e Antalis hanno fornito i migliori risultati, mentre le varietà Aureo e Furio Camillo sono risultate, rispettivamente…
Le varietà di grano duro bio per le prossime semine.
2019
Nelle prove del 17° anno di sperimentazione varietale nazionale sul frumento duro in coltivazione biologica, tra le 19 varietà valutate in 7 campi di prova sono da evidenziare i risultati delle varietà Antalis ed Egeo che alla buona e stabile produzione hanno associato anche un tenore proteico e un peso ettolitrico superiori alle medie.
Environmental impact of Recover cotton in textile industry
2017
A comparative evaluation of the life cycle assessment (LCA) of Recover cotton, obtained from recycled garments, and virgin one, cultivated from traditional and organic crops, has been made based on the quantification of environmental impact categories, such as abiotic depletion, global warming, water use, acidification and eutrophication potential. LCA data reported in the literature for the steps of cultivation, ginning/cutting, and dyeing were compared in order to clearly show the environmental advantages of moving from traditional practices, to organic cultivation and the use of Recover cotton, a novel procedure that involves the production of cotton yarns from coloured and well characte…
Energy-environmental assessment of the UIA-OpenAgri case study as urban regeneration project through agriculture
2020
Abstract Sustainable agriculture is strongly promoted by Agenda 2030 and peri-urban agriculture is considered strategic for agri-food sustainability. Although, innovative farming practices are being implemented, the analysis of their impacts often does not reach the required depth. Within the EU project ‘UIA-OpenAgri - New Skills for new Jobs in Peri-urban Agriculture’, a regeneration process of a peri-urban area in Milan (Italy) was started, through the development of an innovative food hub. 28 innovative foodchains are assessed by a Life Cycle Assessment approach based on primary data collected from the involved start-ups. Non-Renewable Cumulative Energy Demand and the Global Warming Pote…
Choice between alternative investments in agriculture: The role of organic farming to avoid the abandonment of rural areas
2015
Abstract Sicily has a long tradition in citrus fruit cultivation that, with vineyard and olive tree, represents the main Mediterranean tree crops. Since many Sicilian farmers in recent years have decided to abandon conventional lemon orchards, in this paper we have evaluated the financial sustainability of organic lemon production by comparing it with the conventional one. Financial analysis has been carried out in a case study on the northwestern coast of Sicily, considering a 50-year economic life of an orchard. The results, per hectare of area, showed a clear advantage of organic lemon orchard. This was due to fewer labor requirements and to greater market appreciation for organic produc…
Genetic Diversity in Latvian Spring Barley Association Mapping Population
2012
Certified organic crop area is continuously increasing in European Union and in Latvia (Eurostat data), despite somewhat lower yield and higher potential for disease damage in organic farming. It is increasingly recognized that breeding varieties for organic farming requires focus on specific traits that may be less important under conventional agriculture. Molecular markers are becoming essential tools for plant breeding allowing reducing time and cost of development of new varieties by early selection of progeny with desired traits. However, there is lack of information on molecular markers for traits that may be important for organic farming, such as plant morphological traits ensuring c…
Investigating on the environmental sustainability of organic animal products? The case of organic eggs
2020
Abstract The organic farming of laying hens is experiencing a growing trend in Italy, following an increase in consumer demand for organic eggs. The present study aimed to investigate the environmental performance of organic egg production for the first time in the Italian context. To this end, the Life Cycle Assessment (LCA) of organic egg production in a farm rearing laying hens located in Northern Italy was performed. The analysis was carried out in a cradle to farm gate perspective, with 1 kg of eggs selected as functional unit. Primary data relating to animal performances and resources consumed was collected on site, and subsequently integrated with secondary data, including estimates …
Long-term organic farming on a citrus plantation results in soil organic carbon recovery
2019
[ES] Se ha demostrado que el manejo del suelo bajo agricultura ecológica puede aumentar el contenido de carbono orgánico en el suelo moderando el incremento de los gases de efecto invernadero, pero hasta la fecha las evaluaciones cuantitativas basadas en mediciones a largo plazo han sido escasas, especialmente bajo condiciones mediterráneas. En esta investigación se examinaron los cambios en el contenido de carbono orgánico como respuesta a la agricultura ecológica con cobertura vegetal en una plantación de cítricos en el área mediterránea, utilizando una base de datos de 21 años. El incremento de contenido de carbono orgánico en el suelo fue más evidente tras cinco años desde el cambio del…
