Limitations and usefulness of maximum daily shrinkage (MDS) and trunk growth rate (TGR) indicators in the irrigation scheduling of table olive trees
Maximum daily trunk shrinkage (MDS) is the most popular indicator derived from trunk diameter fluctuations in most fruit trees and has been reported to be one of the earliest signs in the detection of water stress. However, ...
Comparison of the water potential baseline in different locations. Usefulness for irrigation scheduling of olive orchards
Deficit irrigation scheduling needs accurate indicators and in recent decades, continuous plant indicators have been developed. However, threshold values that could be useful in commercial orchards are not commonly reported. ...
Assessment of discretely measured indicators and maximum daily trunk shrinkage for detecting water stress in pomegranate trees
Measurements obtained by the continuous monitoring of trunk diameter fluctuations were comparedwith discrete measurements of midday stem water potential and midday leaf conductance (gl)in adult pomegranate trees (Punica ...
Energy Efficiency in Greenhouse Evaporative Cooling Techniques: Cooling Boxes versus Cellulose Pads
Evaporative cooling systems using a combination of evaporative pads and extractor fans require greenhouses to be hermetic. The greatest concentration of greenhouses in the world is located in southeast Spain, but these ...
An index from sap flow records to schedule irrigation in super-high density olive orchards
(International Society for Horticultural Science, 2013)
Regulated deficit irrigation (RDI), recommended for super-high density (SHD) olive orchards, requires a precise control of irrigation. Water must be supplied on the phenological stages when the plant is most sensitive ...
Estudio fenológico y caracterización morfológica de variedades tradicionales de manzano y melocotonero
(Sociedad Española de Ciencias Hortícolas (SECH), 2016)
Las variedades locales de frutales seleccionadas a lo largo de los años por los agricultores, son muy interesantes para preservar la biodiversidad y los recursos fitogenéticos, ya que presentan unas características ...
Plant uptake of phosphorus from sparingly available P- sources as affected by Trichoderma asperellum T34
(Scientific Agricultural Society of Finland. AFSci,, 2015)
The contribution of Trichoderma asperellum T34 to the plant uptake of phosphorus (P) from sparingly phytoavailable forms such as insoluble calcium (Ca) phosphates and phytates was studied. Two experiments with cucumber ...
Seasonal changes of maximum daily shrinkage reference equations for irrigation scheduling in olive trees: influence of fruit load
Maximum daily shrinkage (MDS) is the parameter of daily cycle of trunk diameter most widely suggested in irrigation scheduling for several fruit trees. However, as in other plant-measured approaches, the irrigation decision ...
Organic carbon, water repellency and soil stability to slaking under different crops and managements: a case study at aggregate and intra-aggregate scales
(European Geosciences Union (EGU), 2014)
This research studies the distribution of organic C and intensity of water repellency in soil aggregates with different size and in the interior of aggregates from Mediterranean soils under different crops (apricot, ...
Spatio-temporal vegetation recuperation after a grassland fire in Lithuania
The aim of this work is to study the spatio-temporal effects of a grassland fire in Lithuania. Immediately after the fire, a experimental plot was designed in a east-faced slope. Vegetation cover and height were measured ...
