“…As main barrier to the sector development in this region is the restriction of good quality water for irrigation, leading producers to adopt water resources with high concentration of salts (Silva et al, 2015). This condition leads to a reduction of the soil water potential, leading to a decrease of absorption of water by the plant, and therefore, the nutritional unbalance, by the accumulation of ions as Na + and Cl -, that over time provide a toxic effect leading to restrictions of plant metabolism (Souza et al, 2017;Zhang et al, 2017).…”

The sunflower (Helianthus annuus L.) appears as an income alternative to the producers of the northeastern region of Brazil, however limited by the salinity present in the waters of the region, which makes it necessary to select cultivars that are more adaptable to this situation. On this, the objective was assessing the development of two cultivars of cutting ornamental sunflower with waters of different salinities. The experiment was performed in conditions of protected environment at UFCG, CCTA-Pombal-PB. It was performed in outline of blocks in factorial scheme 5 × 2, being five saline levels (N1 = 0.3, supply water; N2 = 1.5; N3 = 2.7; N4 = 3.9; and N5 = 5.1 dS m-1) and two cutting ornamental sunflower cultivars (Red Sun and Vincents II), with four repetitions and two plants by portion, with a total of 80 experimental units. The irrigation water salinity affected all the analyzed variables, up to estimate level of 2.7 dS m-1 acceptable reductions happen of 10% in the inflorescence and stem of cultivars of ornamental sunflower. The Red Sun cultivar when compared with cultivar Vincents II demonstrated better results in the studied variables.

“…Conforme resultados obtidos por Souza et al (2017), as mudas com maiores valores da relação H/DC apresentam um maior equilíbrio no seu desenvolvimento, sendo mais robustas. Quando a relação H/DC for muito elevada às mudas devem ficar mais tempo no viveiro para reduzir o desequilíbrio entre essas variáveis e garantir um maior sucesso do transplante para o campo.…”

RESUMO O experimento teve como objetivo avaliar o crescimento de mudas de canafístula (Peltophorum dubium) produzidas com o uso de adubação biológica e bioestimulante em substrato orgânico e comercial. O experimento foi conduzido em delineamento experimental em blocos ao acaso, no arranjo fatorial 2 x 4, sendo dois substratos (orgânico e comercial), e quatro adubações com os fertilizantes testados (Testemunha, bioestimulante, fertilizante biológico, fertilizante biológico e bioestimulante), com quatro repetições. Os recipientes utilizados foram tubetes com 120 cm³ onde cada unidade experimental era composta por 30 mudas. Aos 100 dias após a semeadura as mudas foram avaliadas quanto aos seguintes parâmetros: altura da parte aérea (H); diâmetro do coleto (DC); comprimento de raiz (CR); massa seca da parte aérea (MSPA); massa seca de raiz (MSR) e massa seca total (MST); relação da altura da parte aérea/diâmetro de coleto (H/DC); relação entre altura da parte aérea/massa seca da parte aérea (H/MSPA); relação entre massa seca da parte aérea/massa seca de raiz (MSPA/MSR) e índice de qualidade de Dickson (IQD). O uso de fertilizante biológico e bioestimulante não apresentou resultado significativo na qualidade de mudas de Peltophorum dubium, e não apresentaram interação com os substratos testados. Os parâmetros avaliados H, DC, MSPA, MST e as relações H/DC e H/MSPA foram eficientes em indicar mudas de maior qualidade produzidas pelo substrato orgânico. PALAVRAS-CHAVE: bioestimulante, Peltophorum dubium, substrato orgânico.

“…Taking into account the important variables when choosing the best treatment for seedling production, the height to diameter ratio stands out as higher values of this variable represent greater balance in seedling development (Souza et al 2017). However, all treatments with swine wastewater were statistically similar.…”

Substrates based on swine wastewater in the production of seedlings of Guazuma ulmifolia (Malvaceae)

Swine wastewater (sw) can boost seedling growth and development in several species as this residue is rich in nutrients required by plants. This study tested the hypothesis that seedlings of Guazuma ulmifolia grown in a substrate based on swine wastewater showed better physiological and morphological performance. The seedlings were cultivated in seven substrates: T1 - rice husk and vermiculite; T2 - 20% sw; T3 - 40% sw; T4 - 60% sw; T5 - 80% sw; T6 - 100% sw; and T7 - 100% Bioplant®. Were evaluated the height (H), diameter (D), number of leaves (NF), as well as the H to D ratio, chlorophyll indices, gas exchange, biomass, allometric ratios, Dickson Quality Index (DQI), and mortality percentage of the seedlings. The data were analyzed by analysis of variance, and the means were compared by Tukey’s test. The substrates with the highest percentage of swine sludge promoted the highest H, D, NF, chlorophyll indices, gas exchange, stem biomass and IQD. The highest mortality was obtained in commercial substrate (85%) and carbonized rice husk and vermiculite (37.5%). Can be concluded that the substrates with high swine wastewater content were better for seedling G. ulmifolia.
