Water and fertilizers use efficiency in grafted and non grafted tomato plants on soilless culture
(2008)
The improved rooting environment and the absence of pathogens in substrates used in soilless cultures, make the use of grafted plants unnecessary when grown hydroponically. The worldwide water shortages and the increased ...
Effect of a red to far red light filtering plastic film on growth of gardenia (Gardenia jasminoides)
(2006)
The aim of this study was to determine the influence of a light filtering plastic film (red to far red ratio modification) on gardenia (Gardenia jasminoides) growth and to investigate the possibility to use this film as a ...
Alteration of NO - 3, PO 3- 4 and SO 2- 4 Concentration on rose plants in response to greenhouse climate parameters and their concentration in the nutrient solution
(2011)
The objective of this work was to quantify temporal changes of NO - 3, PO 3- 4 and SO 2- 4 concentration on leaves, shoots and roots of rose plants during a short growing period, in response to air temperature, light ...
Calcium, magnesium and potassium concentrations prediction in a recirculated nutrient solution of a greenhouse soilless rose crop
(2006)
The effects of i) biophysical processes such as crop water uptake, and elements absorption and ii) chemical processes such as fertilizers dissolution and pH changes, on Ca2+, Mg2+ and K+ concentration in a recirculated ...
Effect of irrigation frequency on rose flower production and quality
(2006)
A better understanding of the effects of irrigation frequency on flower production and quality of rose plants can help to propose optimal irrigation scheduling. For this purpose, experiments were conducted on a soilless ...
Effect of two irrigation frequencies on rose flower production and quality
(2005)
A better understanding of the effects of irrigation frequency on flower production and quality of rose plants can help to develop optimal irrigation systems. On this purpose experiments were conducted on a soilless rose ...
Nutrient solution management recirculating soilless culture of rose in mild winter climates
(2001)
In a closed hydroponic system with a rose crop, the composition of the nutrient solution in the tank was measured every two days in order to establish the dynamics of the nutrient elements in short-term periods. It was ...
