Sorghum economics under different irrigation methods and water doses
(2009)In this study, an attempt has been made to evaluate the biomass production and the economic results of sorghum growing in Greece under surface and sub-surface drip irrigation and with three different amounts of irrigating ... -
Spatial variation in yield and quality in a small apple orchard
(2010)We describe the yield and quality of apples from a 0.8 ha apple orchard located in northern Greece over two growing seasons and consider the potential for site-specific management. The orchard has two apple cultivars: Red ... -
Spatio-temporal population dynamics and area-wide delineation of Bactrocera oleae monitoring zones using multi-variate geostatistics
(2012)Area-wide integrated pest management requires an understanding of insect population dynamics and definition of suitable techniques to quantify spatio-temporal variability to make better pest management decisions. However, ... -
Statistical tree classification of aphids based on morphological characteristics
(1999)Individual aphids were classified to their clones and separated to their host groups using a novel non-parametric classification tree method. The classification of the individuals was based on morphometric variables measured ... -
A systems analysis of information system requirements for an experimental farm
(2009)A systems analysis and design of information requirements for an experimental farm is presented. This study was carried out on the university farm (UF) at the University of Copenhagen in Denmark. The UF has several farm ... -
Temperature gradients in a partially shaded large greenhouse equipped with evaporative cooling pads
(2003)The main drawback of greenhouse evaporative cooling systems based on cooling pads and extracting fans is the thermal gradient developed along the direction of the airflow. High-temperature gradients of this type can markedly ... -
Towards automated compliance checking based on a formal representation of agricultural production standards
(2011)Production standards in the form of legal regulations or quality assurance labels are playing an increasingly important role in farming. Each farm must therefore gather information on all standards which apply, which may ... -
Toxicity of citrus essential oils against Ceratitis capitata (Diptera: Tephritidae) larvae
(2009)Citrus peel essential oils are considered to constitute the most important resistance factor of citrus fruits against fruit flies. Essential oils were obtained from three sweet orange varieties, one bitter orange and one ... -
Two-Season Study of the Influence of Regulated Deficit Irrigation and Reflective Mulch on Individual and Total Phenolic Compounds of Nectarines at Harvest and during Storage
(2010)The influence of deficit irrigation (Deficit) and reflective mulch (Reflective) of Caldesi 2000 nectarines on the content of individual phenolic compounds was studied at harvest and during storage for 2, 4, and 6 weeks at ... -
Yield prediction in apple orchards based on image processing
(2011)It has been suggested that apple ( Malus * domestica Borkh) flowering distribution maps can be used for site-specific management decisions. The objectives of this study were (i) to study the flower density variability in ... -
Yield prediction in apples using Fuzzy Cognitive Map learning approach
(2013)This work investigates the yield modeling and prediction process in apples (cv. Red Chief) using the dynamic influence graph of Fuzzy Cognitive Maps (FCMs). FCMs are ideal causal cognition tools for modeling and simulating ...
