Genetic diversity among common bean (Phaseolus vulgaris L.) Greek landraces and commercial cultivars: nutritional components, RAPD and morphological markers
(2010)The genetic diversity among the main local landraces and commercial cultivars of Phaseolus vulgaris L. cultivated in Greece, was estimated by studying the morphological, agronomical and physicochemical traits along with ... -
Growth, grain yield and nitrogen use efficiency of Mediterranean wheat in soils amended with municipal sewage sludge
(2014)The application of sewage sludge (SS) to agricultural land can improve soil fertility and physical properties, and enhance crop production. This field study was conducted for two consecutive growing seasons to investigate ... -
Heavy metal concentrations in soils and irrigation waters in Thessaly region, Central Greece
(2005)The purpose of this work was to provide information on heavy metals concentrations in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate ... -
Heavy-Metal Concentration in Tobacco Leaves in Relation to Their Available Soil Fractions
(2009)Tobacco (Nicotiana tabacum) is one of the most important agricultural products in Greece. The accumulation of heavy metals in tobacco leaves in accordance with a possible risk of transferring them to people by smoke is ... -
Herbaceous Plant Diversity and Identification of Indicator Species in Olive Groves in Central Greece
(2013)The present study is aimed at assessing the herbaceous plant diversity and determining the specific species related to different management systems in olive grove ecosystems [organic, conventional (unsprayed), and conventional ... -
How apple responds to boron excess in acidic and limed soil
(2013)Two year-old apple plants (Malus domestica cv. Red Chief Delicious) were grown in an acidic and limed soil, and fertilized with B (0, 1, 3 and 5 mg kg(-1) soil). Fresh matter weight of plants was positively correlated with ... -
Impact of a beneficial and of a pathogenic Fusarium strain on the fingerprinting-based structure of microbial communities in tomato (Lycopersicon esculentum Milll.) rhizosphere
(2011)Fusarium solani strain FsK (FsK), isolated from a plant pathogen-suppressive compost, grows endophytically in tomato roots and controls infestations by Fusarium oxysporum f.sp. radicis-lycopersici (FORL). The effect of ... -
The impact of biological pesticides on arbuscular mycorrhizal fungi
(2012)Arbuscular mycorrhizal (AM) fungi have a key role for plant nutrition in organic farming systems where crop protection relies on biopesticides. Although these are considered safe, their effects on non-target organisms, ... -
Impact of New Soil Amendments on the Uptake of Lead by Crops
(2013)In the present article, the reclamation of lead (Pb)-contaminated soils by adding zeolite, bentonite, goethite, and two newly produced adsorbents consisting of zeolite and goethite (systems I and II) was studied. These ... -
Incubation experiments on net nitrogen mineralization in organic Greek soils
(2005)Aerobic incubation experiments were conducted in organic surface samples collected from arable soils of Philippoi, in Northern Greece. Laboratory experiments were carried out to investigate the nitrogen (N) mineralized ... -
Influence of biosolids application on some soil physical properties
(2005)Biosolids land application is a widely accepted option throughout the world because of its beneficial effects on soil chemical and physical properties and crop yield. These effects-e specially those pertaining to soil ... -
Influence of liming and nitrogen forms on boron uptake by tobacco
(2005)The purpose of this study was to investigate the influence of soil liming and fertilizer nitrogen forms on the availability of soil B and its uptake by tobacco plant. A field experiment was conducted on an acid Typic ... -
KINETIC-STUDY OF PHOSPHORUS DESORPTION BY ALFISOLS AND ENTISOLS
(1993)The kinetics of phosphorus (P) desorption by six Greek soils, four Alfisols and two Entisols, have been studied. By the addition of several amounts of P fertilizers at different water/soil rations and different contact ... -
Mineralization of Organic-Amendment-Derived Nitrogen in Two Mediterranean Soils with Different Organic-Matter Contents
(2013)The use of organic fertilizers in lands with low organic-matter content, such as those found in the Mediterranean region, is an attractive option for enhancing soil quality and fertility status. However, it is difficult ... -
Monitoring the Variability of Nitrogen and Cadmium Concentrations in Soils and Irrigation Water in the Almyros Area of Central Greece
(2009)The main purpose of this investigation was the monitoring of nitrogen (N) and cadmium (Cd) levels in soils and irrigation water samples in an intensively cultivated area in central Greece. From 2005 to 2007, soil as well ... -
Nitrogen and phosphorus availability to ryegrass in an acidic and limed zeolite-amended soil
(2012)Nitrogen and P fertilization increases crop yields, especially in acidic soils, but its effect may be minimized by various N loss and P retention processes. Zeolite may enhance N and P fertilizer efficiency. The aim of ... -
Nitrogen, Phosphorus, and Potassium Availability in Manure- and Sewage Sludge-Applied Soil
(2015)A field experiment with wheat (Triticum aestivum L.) was established over two growing seasons where farmyard manure and sewage sludge, along with conventional fertilizer, were added to soil. We found that ammonium N was ... -
Olive mill wastewater affects the structure of soil bacterial communities
(2010)Land spreading of olive mill wastewater (OMW) has beets proposed as a useful means for its disposal. However, there is no information regarding the impact of OMW soil applications on the structure of bacterial communities. ... -
Phosphorus Availability in Low-P and Acidic Soils as Affected by Liming and P Addition
