“…3) around the roots. This is in agreement with studies which indicated that continual reuse of the drain solution in closed soilless culture usually increases EC of the circulating solution (Baas and Van den Berg, 1999;Bar-Yosef et al, 2001;Daood and Karam, 2007;Karam and Al-Daood, 2005). This effect was evident in the current study when the nutrient solution N was used alone for irrigation (Fig.…”

A plastic greenhouse study was implemented to evaluate the potential use of treated wastewater for irrigation of Asiatic lily 'Brunello' grown in zeolite. Plants received the following treatments: a nutrient solution (N) alone, (N) mixed with treated wastewater (W) at rates of 3N:1W, 1N:1W and 1N:3W respectively. A closed system was used in which the drain solution was circulated for several days until its electrical conductivity reached 2.3 dS m -1 , after which fresh irrigation solutions were used to start a second cycle of circulation. The results indicated that plants irrigated with (N) or 3N:1W solution had the longest stems (34.4 and 36.2 cm) respectively, peduncles and buds (about 4.5 cm), and the greatest shoot (3.4 and 3.8 cm) and bud mass (14.95 and 17.6 g) respectively. Plants irrigated with 1N:3W solution had the highest dry mass tissue content of K (3.06 g kg -1 ) and B (35.5 mg kg -1 ). Plants irrigated with 1N:1W or 1N:3W were inferior to other plants. It can be concluded that 1N:3W mixture may be used for production of high quality cut flowers of lily. Moreover, it is expected to save 3.4 litres m V raziskavi, izvedeni v plastenjaku, je bila ovrednotena potencialna uporaba odpadne vode za gojenje azijskih lilij 'Brunello' gojenih na zeolitu. Opravljena so bila naslednja obravnavanja: uporaba čiste hranilne raztopin (N), mešanica hranilne raztopine (N) z odpadno vodo (W) v razmerjih 3N:1W, 1N:1W in 1N:3W. Uporabljen je bil zaprt sistem, v katerem je raztopina krožila več dni, dokler njena električna prevodnost ni dosegla 2,3 dS m -1 , potem je bila uporabljena sveža raztopina za začetek drugega kroga poskusa. Rezultati so pokazali, da so imele rastline, ki so bile namakane samo s hranilno raztopino (N) ali z mešanico 3N:1W, najdaljša stebla (34,4 in 36,2 cm), cvetne peclje in popke (okrog 4,5 cm), največjo maso poganjkov (3,4 in 3,8 cm) in popkov (14,95 in 17,6 g). Rastline, ki so bile zalivane z raztopino 1N:3W, so imele največjo suho maso tkiv, največjo vsebnost K (3,06 g kg -1 ) in B (35,5 mg kg -1 ). Rastline, ki so bile namakane z mešanicami raztopin 1N:1W in 1N:3W so bile slabše v primerjavi s prejšnjimi. Zaključili bi lahko, da bi za pridelavo zelo kvalitetnega rezanega cvetja azijskih lilij lahko uporabili mešanico raztopin 1N:3W in s tem prihranili 3,4 l m -2 hranilne raztopine in 1850, 347 in 1870 mg m -2 dan -1 N, P in K.

The objective of this study was to develop a sensitive means of control to optimize nutrient concentrations in the root zone of a soilless system, considering plant water and nutrient uptake, and solution circulation rates. A model is proposed to simulate ornamental plants' growth in a channel with a non-interacting soilless substrate, irrigated by point sources with constant discharge rates, spaced uniformly along the channel. The model accounts for compensation for transpiration water losses and consequent salinity buildup, and its interactions with plant growth and nutrient uptake. The added water may contain given concentrations of nutrients and/or toxic (saline) compounds, which would cause salinity buildup. Uptake of each solute is specific, according to a Michaelis-Menten kinetics mechanism, but passive uptake by the transpiration stream is also accounted for. Plant growth is affected by time/ age and ionic balance in the solution. The model was calibrated with lettuce (Lactuca sativa L.) plants grown in volcanic ash. Simulation of potassium concentration change as a result of discharge rate and emitter spacing revealed that the two parameters could compensate one for the other, once a target lower limit is set. Potassium appeared to be most sensitive to sodium accumulation in the growth medium; this accumulation changed ionic concentration balance, which affected pH and bicarbonate concentration. Passive uptake of calcium by the transpiration stream is highly affected by the root fraction involved, but its calculated contribution is below published values is highly affected by the root fraction involved, but its calculated contribution is below published values.Abbreviations: LAI -leaf area index; NFT -nutrient film technique; RL -root length
