“…Research of various crops and their growth in terms of soil packing (Bayhan et al, 2002), sowing date and its density for different conditions of hydration, access to light (Ferreira and Abreu, 2001), parasites (Grenz et al, 2008) and stress conditions were conducted alongside the research of germination and growth of sunflowers. Sunflower kernels are a rich source of oil and may be used for food (Mamat et al, 2005;Smith et al, 2007), as ornamental flowers (Friedman et al, 2007), as an admixture to diesel fuel as well as biodiesel in the form of methyl esters made from sunflower oil (Rashid et al, 2008).…”

A b s t r a c t. The impact of a variable magnetic field, magnetically treated water and a combination of both these factors on the germination of seeds and the final mass at the initial stage of growth sunflower plants was presented. Investigations were carried out in pots filled with sand, tin an air-conditioned plant house with no access to daylight using fluorescent light as illumination. A statistical significance positive impact was achieved for the samples subjected to the interaction of both stimulating factors simultaneously, the magnetic field and the impact of treated water several times on the speed of seed germination and final plant mass. Negative impacts were obtained for the majority of the test cases, for the magnetically treated water, the short duration of activity of the magnetic field and for the connection of the magnetic field and low-flow times.K e y w o r d s: seed stimulation, magnetic field, magnetically treated water

“…However, the higher values were obtained during the two initial months with 12.05 and 11.77 cm, for T 2 and T 1 , respectively (Table 4). Friedman et al (2007) did not observe statistical differences for the length of the celosia flower spike when fertigated with effluent. However, 46 and 72% of cut flowers irrigated with fresh water and effluent were above 60 cm in the first harvest, while in the second harvest 9.3 and 18.6% of flowers were longer.…”

This paper evaluates the nutritional impact on growth, production and quality variables of gerbera crop when fertigated with treated domestic effluents. An experiment was carried out in greenhouse at the Embrapa Meio-Norte in Teresina, in the State of Piauí, Brazil, from July to October 2007. A completely randomized experimental design with five treatments and five replications was adopted. The treatments investigated were T 1 -100% of water and nutritional requirements of crop were met with chemical fertigation (N e K 2 O); T 2 -25% volume of water through fertigation and 75% treated wastewater effluents (TWE); T 3 : 50% volume of water through fertigation and 50% TWE; T 4 : 75% volume of water with fertigation and 25% TWE; and T 5 -100% volume of water supplied through TWE. Leaf growth and plant development were favored by the application of 50% fertigation and 50% TWE (T 3 ). As for commercial requirements, the best results for number of flowers were obtained with T 4 . However, concerning quality, T 2 produced flowers in July and August with longer stems, but in the months of September and October, no treatment achieved this standard due to high temperature and low relative humidity of the air in the region. Key words: water reuse, fertigation, Gerbera jamesoniiCultivo de gérbera irrigada com efluentes domésticos tratados RESUMO Com o objetivo de avaliar os efeitos nutricionais sob as variáveis de crescimento, produção e qualidade da gérbera (Gerbera jamesonii) quando fertigada com efluentes domésticos tratados conduziu-se um experimento em ambiente protegido na unidade da Embrapa Meio-Norte, em Teresina, PI, utilizando-se delineamento estatístico inteiramente casualizado com cinco tratamentos e cinco repetições. Os tratamentos estudados foram: T 1 -100% das necessidades hídrica e nutricional das culturas atendidas mediante fertigação (N e K 2 O); T 2 -75% do volume de água residuária tratada (ART) associada a 25% de fertigação; T 3 -50% de ART associada a 50% de fertigação; T 4 -25% de ART associada a 75% de fertigação e T 5 -100% de ART. O crescimento e o desenvolvimento foliar foram favorecidos pelo tratamento de 50% de fertigação associados a 50% de ART (T 3 ). Quanto às exigências comerciais em número de flores, os melhores resultados foram obtidos em T 4 , porém, em termos de qualidade, o T 2 apresentou maior altura das hastes florais, nos meses de julho e agosto; já nos meses de setembro e outubro nenhum tratamento conseguiu alcançar este padrão de qualidade em virtude de altas temperaturas e baixa umidade relativa na região.Palavras-chave: reúso de água, fertigação, Gerbera jamesonii 1 Part of the Master Dissertation of the first author presented at

“…During 12 months of irrigation using TWW, the visible appearance of the plants, their growth, the quantity and size of the flowering stems were not affected by the irrigation treatments. Friedman et al [7] also examined the effects of two types of irrigation water on the chemical composition of soil and leaves, flower yield and postharvest performance. They used PW and TWW with EC equal to 0.6 dS/m for PW and 7.8 dS/m for TWW.…”

Impacts of Treated Wastewater Reuse on Some Soil Properties and Production of Gladiolus communis

Two experiments, one in Open Field (OF) and the other inside a Greenhouse (GH), were conducted at Al-Jubeha Agricultural Research Station -The University of Jordan, to study the effect of Treated Wastewater (TWW) on soil chemical and physical properties. It was also intended to find the effect of TWW on spike quality of gladiolus. Five water treatments were used for both experiments, T1:100% Potable Water (PW); T2:100%TWW; T3:25%PW +75%TWW; T4:50%PW+50%TWW; and T5:75%PW+25%TWW. The design for both experiments was Randomized Complete Block Design (RCBD). The results in both experiments showed high accumulation of salts in soils for all treatments with the highest accumulation values in soil T2. Soil organic matter (OM) and N were reduced after planting for all treatments in the GH treatments, but OM remained almost the same in the OF treatments. There was an increase in Zn, Pb, and Cu microelements in soils for all treatments. Soil physical properties such as aggregate stability was reduced for all treatments significantly after planting by about 40% for the GH treatments, and nonsignificantly by about 3-12% for the OF treatments. Soil water retention curve and pore size distribution did not significantly change after planting for the soil for all treatments in both experiments. Plant properties, from both experiments, were affected by TWW irrigation. Parameters such as: spike length, spike diameter, corm size, number of florets per spike, and the number of cormels per corm were found to be affected by water treatments.It gave the worst quality for plants that irrigated with 100% TWW for both experiments. Based on results obtained from both experiments, it was found that soils were affected negatively by TWW irrigation for their chemical and physical properties. Use of TWW when mixed with some PW for irrigation of non-edible plants such as cut flowers gave better results than using PW alone.
