Energy flow for integrated apple production in Greece
(2006)Integrated production requires constant improvement of methods employed to achieve high fruit quality and yield with minimal inputs. This work was undertaken to evaluate the energy inputs for apple production, to identify ... -
Environmental and economic evaluation of N fertilizer rates in a maize crop in Italy: A spatial and temporal analysis using crop models
(2012)Crop simulation models have the potential to assess the risk associated with the selection of a specific N fertilizer rate, by integrating the effects of soil-crop interactions on crop growth under different pedo-climatic ... -
Evaluation of teflubenzuron residue levels in grapes exposed to field treatments and in the must and wine produced from them
(1999)Dissipation of benzoylurea insecticide teflubenzuron in grapes exposed to field treatments was evaluated. Vines of a white grape vineyard located in central Greece were sprayed twice, at a 28-day interval, with a commercial ... -
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ... -
Extension and evaluation of a model for automatic drainage solution management in tomato crops grown in semi-closed hydroponic systems
(2015)In the present paper, a model previously developed to simulate the course of Na+ accumulation in closed hydroponic systems as a function of plant water consumption was further extended so as to be operative also in semi-closed ... -
Farm machinery management information system
(2015)Management of farming operations is currently rapidly changing toward a systems perspective integrating the surroundings in terms of environmental impact, public entities and documentation of quality and growing conditions. ... -
Farm management information systems: Current situation and future perspectives
(2015)Farm Management Information Systems (FMIS) in agriculture have evolved from simple farm record-keeping into sophisticated and complex systems to support production management. The purpose of current FMIS is to meet the ... -
Feasibility of a modelling suite for the optimised biomass harvest scheduling
(2010)It has been estimated that 1/3 of forage grass is harvested drier than the optimum moisture content while another 1/3 is harvested while too wet This indicates that dedicated systems supporting decisions that affect grass ... -
Field persistence studies on pendimethalin residues in onions and soil after herbicide postemergence application in onion cultivation
(1998)Field studies were undertaken to evaluate the fate of pendimethalin residues in spring and dry onions, after postemergence application of the herbicide in a clay soil onion planting in central Greece, at rates of 1.32 and ... -
A five-point penetrometer with GPS for measuring soil compaction variability
(2013)Measuring soil compaction is a factor of interest to monitor soil fertility, which plays an important role in crop production cycle. Soil penetration resistance is the most commonly used method to measure soil compaction. ... -
A flow-shop problem formulation of biomass handling operations scheduling
(2013)Currently, the planning of the biomass collection operations is performed relying on the contractor's experience without the use of any dedicated planning tool. It is expected that more explicitly formulated planning tools ... -
A four nation survey of farm information management and advanced farming systems: A descriptive analysis of survey responses
(2011)The aim of this paper is to present the descriptive results of the survey responses that explore the perception of advanced information systems among four European countries: i.e. Denmark, Finland, Germany and Greece. The ... -
Fruit Volatiles, Quality, and Yield of Watermelon as Affected by Grafting
(2014)The aim of the present study was to examine the effect of grafting of watermelon hybrids 'Obla F-1' and 'Vanessa F-1' on to Cucurbita maxima x Cucurbita moschata rootstock TZ 148 and Lagenaria sp. rootstock 'Dias F-1', on ... -
A fuzzy inference system to model grape quality in vineyards
(2014)Fuzzy inference systems (FIS) are particularly suited for aggregating multiple data to feed multi-variables decision support systems. Moreover, grape quality is a complex concept that refers to the simultaneous achievement ... -
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 ... -
Impact of Nitrogen and Sulfur Fertilization on the Composition of Glucosinolates in Relation to Sulfur Assimilation in Different Plant Organs of Broccoli
(2009)Broccoli (Brassica oleracea var. italica) is one of the most important winter season vegetables and a rich source of chemoprotective molecules, including glucosinolates (GSL). The aim of this study was to investigate the ... -
Induction of embryo development and fixation of partial interspecific lines after pollination of F-1 cotton interspecific hybrids (Gossypium barbadense x Gossypium hirsutum) with pollen from Hibiscus cannabinus
(2005)The possibility of inducing embryo development after pollination of F-1 interspecific cotton hybrids ( Gossypium barbadense x Gossypium hirsutum) and their reciprocals with pollen from Hibiscus cannabinus was investigated. ... -
Influence of Ambient Ozone Pollution on Olive Leaf Gas Exchange Irrigated with Saline Water
(2011)Saline water is often available for irrigation and ambient ozone pollution is significant in the Mediterranean region. These two factors may negatively affect cultivated plant productivity. We studied the effects of a ... -
Influence of leaf area index on canopy energy partitioning and greenhouse cooling requirements
(2002)Canopy transpiration, which represents the major cooling process in greenhouses, depends strongly on the crop leaf area index I-LA. In this paper, the influence Of I-LA on canopy and greenhouse energy balance of a soilless ... -
