“…In order to evaluate the quality of seedlings, the evaluation of a single variable is not recommended, in this case DQI can be an interesting alternative, since it integrates important plant growth variables, also present in the production of seedlings of fruit and tree species (DIAS et al, 2012;AMARAL et al, 2016;LUSTOSA FILHO et al, 2015;SOUSA et al, 2015). Thus, the higher the DQI, the higher will be the standard quality of the seedlings.…”

In Brazil, there is already a recommendation for the production of cassava seed-cuttings for the production of seedlings originated from micropropagation, which may be extended for the production of seedlings obtained from cuttings from healthy plant stems, in order to avoid the spread of diseases. Therefore, it is essential to establish adequate cultivation substrates of easy acquisition which may stimulate the growth of seedlings, both to reduce the nursery period, as well as the seedling’s production costs. The objective of this work was to evaluate the effect of organic fertilizers made from bovine and goat manures, and tree pruning residues, to produce seedlings of three cassava varieties. The plots were set in a completely randomized design, with six replicates. The treatments consisted of three cassava genotypes (BRS Formosa, BRS Tapioqueira and BRS Kiriris) and five proportions of organic fertilizer: soil (0: 100, 20:80, 40:60, 60:40 and 80:20). The evaluations were performed 30 and 45 days after planting (DAP). There were isolated effects for shoot dry mass, total dry mass, leaf area and number of leaves. Interactions were verified for root length, chlorophyll a and total chlorophyll index, root dry mass and shoot dry mas/root dry mass ratio 45 DAP. The organic fertilizer stimulated the initial growth of cassava seedlings in the three varieties studied in the proportion of 50% of organic fertilizer and 50% of Latosol. Varieties BRS Formosa and BRS Kiriris showed the highest Dickson Quality Scores. Genotypes reacted efficiently to organic fertilization and can be propagated on these easily acquisition cultivation substrates.

“…For instance, Mizobata et al (2016) observed an increase in the SDM in H. stilbocarpa plants when organic residue was added to the substrate. Amaral et al (2016) demonstrated that a substrate containing 50% plant compound provided higher RDM, SDM and TDM in plants of Leucaena leucocephala (Lam.) de Wit.…”

Many Brazilian reservoirs are intensely submitted to the silting process, particularly the small and medium size ones. The study aimed to examine the feasibility of using silt sediment to grow sunflower plants under conditions of water stress, by evaluating its effects on the relative chlorophyll contents, dry matter and antioxidative enzyme system. The study was conducted under greenhouse conditions at the Instituto Federal do Ceará Campus Maracanaú, Brazil. The sunflower seeds were sown in buckets containing 1) sand; 2) sand + manure/mixed organic fertilizer; 3) sand + 91.8 g of sediment, and 4) sand + 183.6 g of sediment. The sediment was collected from the Tijuquinha reservoir, Northeast of Brazil. The plants were watered daily to 70% field capacity. At 16 days after sowing, irrigation to half of each group of seedlings was suspended. The experimental design was completely randomized in a 2 × 4 factorial with five replicates. The data of each harvest time were analysed by analysis of variance and the means were compared by Tukey's test (P ≤ 0.05). The addition of silt sediment improved the variables (relative chlorophyll content, and shoot and total dry matters) compared to plants grown in substrate containing sand and sand + compost/mixed organic fertilizer, respectively. In general, a greater increase in the variables was observed with the 200% nitrogen recommendation treatment than the other treatments studied. It is possible that the silt sediment from reservoirs can be an alternative to chemical fertilizers for plant cultivation, reducing production costs, providing improvements in the quality of potable water and restoring the storage capacity of surface reservoirs lost by siltation.

“…Species such as Leucaena leucocephala (Lam.) and Sesbania virgata showed better quality seedlings when grown on substrates composed by organic compost from tree prunings and animal manure, in proportions of 50:50 and 80:20 (organic compound:soil), respectively (Sousa et al, 2015;Amaral et al, 2016). As well as Enterolobium contortisiliquum grown on substrates made by urban waste compost at proportions of 80:20 (compound: soil) (Nóbrega et al, 2008).…”

The objective of the present research was to evaluate different types and proportions of organic wates and soil classes for substrate formulation for Caesalpinia pulcherrima cultivation. The experiment was performed in a greenhouse, and treatments were composed by two soil classes (Oxisol and Entisols), three types of residues (organic compound from pruning + manure, urban waste compost and residue from the extraction of Agave sisalana fibers) and five residue:soil proportions (0:100, 20:80, 40:60, 60:40, 80:20, v/v). Plant height, stem diameter, number of leaves, rates of a, b and total chlorophyll, leaf area, root length, shoots and roots dry weight and the Dickson Quality Index were evaluated 90 days after sowing. All three types of residues evaluated showed potential to be used in the elaboration of growth substrates for the production of C. pulcherrima L. Sw. seedlings. The substrates formulated with 33%, 23% or 5% of organic tree pruning + animal manure, urban waste compost and residue of the Agave sisalana fiber extraction, respectively, promoted better quality of seedlings 90 days after sowing, regardless of the soil class.
