A Bilevel Linear Programming Model for Developing a Subsidy Policy to Minimize the Environmental Impact of the Agricultural Sector
(2022)The agro-food industry, while critical for establishing food security, is the most environmentally impactful industry since it causes biodiversity loss and the conversion of natural land to farms and pastures, requires ... -
A Comparison between Variable Deficit Irrigation and Farmers’ Irrigation Practices under Three Fertilization Levels in Cotton Yield (Gossypium hirsutum L.) Using Precision Agriculture, Remote Sensing, Soil Analyses, and Crop Growth Modeling
(2022)The major global challenge for the coming decades will be increasing crop production with less water consumption. Precision agriculture (PA) and variable deficit irrigation (VDI) are management strategies that help farmers ... -
Effects of Alternative Fertilization and Irrigation Practices on the Energy Use and Carbon Footprint of Canning Peach Orchards
(2022)Throughout peach orchards in Greece, plant protection, fertilization and irrigation are often conducted empirically, negatively affecting energy use efficiency and greenhouse gas emissions (GHG emissions). The aim of this ... -
Environmental geochemical research for the levels and the sources of toxic metals in the agricultural soils of dimitraeleftherion and platycampos region, Thessaly, Greece
(2007)The contents of eleven elements (Cu, Pb, Zn, Ni, Co, Mn, Fe, As, V, Cr and Mg) have been assayed in the agricultural soils of Dimitra-Eleftherion and Platycampos region (Thessaly, Greece). One hundred twenty two top soil ... -
Exploring precision farming scenarios using fuzzy cognitive maps
(2017)One of the major problems confronted in precision agriculture is uncertainty about how exactly would yield in a certain area respond to decreased application of certain nutrients. One way to deal with this type of uncertainty ... -
Growth and productivity of Salvia officinalis L. under Mediterranean climatic conditions depends on biofertilizer, nitrogen fertilization, and sowing density
(2021)Salvia officinalis L. is an important medicinal herb of high soil and climatic adaptability and thus the main goal of the current study is to investigate the effect of mycorrhizae, the plant density and the nitrogen ... -
Herbal plants- and rice straw-derived biochars reduced metal mobilization in fishpond sediments and improved their potential as fertilizers
(2022)Fishpond sediments are rich in organic carbon and nutrients; thus, they can be used as potential fertilizers and soil conditioners. However, sediments can be contaminated with toxic elements (TEs), which have to be immobilized ... -
Innovative Nitrogen Fertilizers Effect on Cotton Cultivation
(2020)Fertilizer enhancement is determined by chemical and physical characteristics, environmental safety, and mechanical stress stabilization, etc. In order to assess the reaction of cotton cultivation to distinct kinds of ... -
Irrigation and nitrogen application affect Greek oregano (Origanum vulgare ssp. hirtum) dry biomass, essential oil yield and composition
(2020)Oregano is a perennial crop native to the mountains, which has been extensively cultivated in the last decade. Due to the growing interest in oregano cultivation, the aim of this study was to investigate the effect of ... -
Life cycle assessment of variable rate fertilizer application in a pear orchard
(2020)Precision Agriculture (PA) is a crop site-specific management system that aims for sustainability, adopting agricultural practices more friendly to the environment, like the variable rate application (VRA) technique. Many ... -
On-Farm Evaluation of Variable Rate Fertilizer Applications Using Yield-Based Mathematical Formulae in a Greek Apple Orchard
(2020)The objectives of this study were to compare variable rate and uniform fertilizer applications in apple (Malus domestica Borkh.) and its effect on production and economic return. In the study, 59.6% and 63.4% less fertilizer ... -
Soil dynamics of Cr(VI) and responses of Portulaca oleracea L. grown in a Cr(VI)-spiked soil under different nitrogen fertilization regimes
(2022)The reduction potential of the highly toxic Cr(VI) to the inert Cr(III) in an alkaline soil was studied during a 50-day experiment with Portulaca oleracea L. grown in pots. We aimed at assessing whether our test species ... -
Weed flora and seed yield in quinoa crop (Chenopodium quinoa Willd.) as affected by tillage systems and fertilization practices
(2015)The effects of tillage system and fertilization regimes on weed flora in quinoa (Chenopodium quinoa Willd.) were evaluated by means of two field experiments in 2011 and 2012. The experiments were laid out in a split-plot ...
