Divergent Mass Selection for Leaf Chlorophyll Content Measured Using Chlorophyll Meter Readings in a Maize Composite Population
(2011)Leaf chlorophyll content is correlated with photosynthetic activity indicators and leaf nitrogen concentration. Three cycles of divergent mass selection for chlorophyll content were performed to estimate heritability, ... -
The effect of an intelligent surface drip irrigation method on sorghum biomass, energy and water savings
(2013)Over the last few decades, precipitation has decreased as a result of climate change. This change increases crop water requirements, while irrigation water is wasted because of improper irrigation scheduling. Soil moisture ... -
Effect of grafting on eggplant leaf gas exchanges under mediterranean greenhouse conditions
(2011)Grafting is an easier and faster approach than plant breeding to take advantage of both existing resistant plants, especially wild cultivars, and high-bred cultivars. The aim of this study was to investigate the changes ... -
Effect of grafting on growth, performance and yield of aubergine (Solanum melongena L.) in greenhouse and open-field
(2011)Seedlings of aubergine (Solanum melongena L.) cv. 'Rima' were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes 'Heman' (Lycopersicon hirsutm) and 'Primavera' (Lycopersicon ... -
Effect of misting on transpiration and conductances of a greenhouse rose canopy
(2001)The influence of greenhouse humidity control on the transpiration rate (lambdaE(c)). sensible heat flux (H-c) and bulk stomatal conductance (g(c)) of a soilless rose canopy (Rosa hybrida. cv. First Red) was studied in a ... -
Effect of modern irrigation methods on growth and energy production of sweet sorghum (var. Keller) on a dry year in Central Greece
(2007)The subject of this project is to estimate the growth and productivity of sweet sorghum [Sorghum bicolor (L.)] var. Keller, under two different irrigation methods - the conventional surface drip method (two treatments) and ... -
The effect of water vapour adsorption on soil moisture content under Mediterranean climatic conditions
(1998)The effect of water vapour adsorption on the soil moisture content of different soils under semi-arid climatic conditions (Greece) was evaluated. Time domain reflectometers were used for continuously monitoring soil moisture ... -
Effects of fertilization and tillage system on growth and crude protein content of quinoa (Chenopodium quinoa Wild.): An alternative forage crop
(2014)A field experiment was conducted to determine the effects of fertilization and tillage on growth, yield and quality of quinoa crop (Chenopodium quinoa Willd.). The agronomic performance and nutritive value of quinoa was ... -
Effects of organic and inorganic amendments on weed management in sweet maize
(2012)Field experiments were conducted to determine the effects of organic and inorganic amendments on weed suppression in sweet maize cultivation (Zea mays L.). A randomized complete block design was employed with four replicates ... -
Effects of Organic Farming on Winter Plant Composition, Cover and Diversity in Olive Grove Ecosystems in Central Greece
(2013)The present study aimed to assess the effects of organic farming in comparison with conventional on plant composition, plant cover (%), diversity [species richness, Shannon, Simpson, and evenness (Pielou's) indexes] and ... -
Effects of Pea Cultivation as Cover Crop on Nitrogen-Use Efficiency and Nitrogen Uptake by Subsequent Maize and Sunflower Crops in a Sandy Soil in Central Greece
(2013)The long-term positive effects of cropping systems involving rotation with cover crops on soil properties and the environment are well recognized. The present work concerns a 3-year field experiment focusing on two cropping ... -
Efficacy of layer treatment with methoprene for control of Rhyzopertha dominica (Coleoptera: Bostrychidae) on wheat, rice and maize
(2011)BACKGROUND: Insect growth regulators are promising alternatives to traditional pesticides in stored grain. The efficacy of the juvenile hormone analogue methoprene was evaluated as a layer treatment in a laboratory experiment ... -
Efficacy of the pyrethroid alpha-cypermethrin against Bactrocera oleae populations from Greece, and improved diagnostic for an iAChE mutation
(2008)BACKGROUND: The most important pest of olive orchards worldwide is the olive fruit fly Bactrocera oleae (Gmelin). Its control in Greece has been based on organophosphates (OPs), but their intense use has led to the development ... -
Estimation of unsaturated flow in layered soils with the finite control volume method
(2001)Water movement in unsaturated soil is described by Richards' equation, which is strongly nonlinear and cannot be solved analytically. For this reason numerical methods such as finite difference and finite element methods ... -
Evaluation of cover-cropping managements on productivity and N-utilization efficiency of kenaf (Hibiscus cannabinus L.), under different nitrogen fertilization rates and soil types
(2013)Biomass productivity, nitrogen recovery fraction and nitrogen utilization efficiency (NUE) of kenaf (Hibiscus cannabinus L.) cultivar Tainung 2 were tested, under three Lens culinaries treatments (incorporated, harvested ... -
Evaluation of rootstocks for watermelon grafting with reference to plant development, yield and fruit quality
(2012)The effect of grafting and post-grafting temperature on the plant development of two watermelon cultivars at transplantation and on subsequent fruit quality was studied. Watermelon cv. Sugar Baby and Crimson Sweet were ... -
Evaluation of seed cotton (Gossypium hirsutum L.) production and quality in relation to the different irrigation levels and two row spacings
(2012)The effect of row spacings and irrigation levels on the earliness of seed production of cotton was investigated under the Mediterranean environment of central Greece. This particular cotton growing area is exposed to risk ... -
EVALUATION OF THE ALLELOPATHIC POTENTIAL OF QUINOA (CHENOPODIUM QUINOA WILLD.)
(2013)The allelopathic effects of three plant tissues of Chenopodium quinoa (leaves, roots and inflorescences) on oat growth were investigated using in vivo tests. Oat growth (fresh and dry weights of above and underground parts) ... -
