“…The results found in the present study for plant height corroborate those reported by other authors (Souza et al, 2010;Andrade et al, 2012;Freitas et al, 2012), who observed increment in the height of plants irrigated with wastewater. The increment in mean PH observed in sunflower plants irrigated with 100% domestic effluent is probably due to the content of nutrients dissolved in the domestic effluent.…”

“…Other studies with the sunflower crop have found increments in internal and external capitulum diameter of plants irrigated with wastewater in comparison to those irrigated with public-supply water (Souza et al, 2010;Andrade et al, 2012;Freitas et al, 2012). Corroborating the results found, Biscaro et al (2008) also observed increase in capitulum diameter in sunflower, cv.…”

“…Anão de Jardim) irrigated with wastewater dilutions and did not observe significant differences between treatment means for the variables BF and CFO, which occurred on average at 49 and 52 days, respectively. Andrade et al (2012) also did not observe significant differences for the variables beginning of flowering (BF) and capitulum full opening (CFO) in a study with different genotypes of ornamental sunflower irrigated with treated wastewater and public-supply water.…”

“…However, thinner stems were observed in sunflower plants irrigated with the lowest dilutions of human urine in domestic effluent (2, 4 and 6% HU) in the evaluations at 22 DAT and at harvest (Tables 4 and 6). Andrade et al (2012) In the harvest of flower stems, all treatments met the limit range from 5 to 15 mm, established as quality standard for SD in ornamental sunflower plants (Grieve & Poss, 2010) (Table 6). According to Curti (2010), it is desirable that the flower stem have greater diameter and resistance to support the inflorescence, which is heavier in sunflower plants compared with other species of cut flowers.…”

This study aimed to evaluate growth and production of ornamental sunflower (Helianthuns annuus L.), cv. Anão de Jardim, irrigated with dilutions of human urine in treated domestic effluent. The experiment was carried out in completely randomized design with five treatments and four replicates, in a greenhouse. Treatments consisted of four dilutions of human urine (0, 2, 4 and 6%) in treated domestic effluent and fertilization with 50% of the recommendation of mineral fertilizer. Plants irrigated with human urine dilutions (2, 4 and 6%) in treated domestic effluent and fertilized with 50% of the recommendation of nitrogen (N) and potassium (K) showed reductions of growth and production, while those irrigated with 0% human urine dilution in treated domestic effluent and fertilized with 50% of N and K recommendation exhibited similar performance to those irrigated with public-supply water and fertilized with 100% of the recommendation of mineral fertilizer. The obtained results allow to infer on the viability of replacing public-supply water by treated domestic effluent for irrigation, with reduction of 50% in N and K fertilization, without prejudice to the growth and production of ornamental sunflower plants, cv. Anão de Jardim.

“…Seu formato exótico e o tom amarelo alaranjado intenso de suas flores acrescentam vida e dinamismo aos ambientes. 3 A inflorescência do girassol é a parte da planta visada na comercialização de flores. Para o girassol granífero, a inflorescência se desenvolve com a indução da fase reprodutiva, a partir do aumento do diâmetro do caule, dando origem ao receptáculo floral, de onde surgirão as flores propriamente ditas.…”
