“…Linear effect was verified for this variable, obtaining better MSPA/MSR index in plants cultivated with only soil, once they showed better mass distribution ( Figure 3A). Similar results were observed by Sousa et al (2015) in Sesbania virgata (Cav. Pers) cultivated in carnauba residues, which responded linearly to the addition of this compost to the substrate.…”

“…In Sesbania virgata (Cav. Pers), an increment in such ratio was observed while incrementing the proportions of rice husk until the estimated proportion, demonstrating the negative effect of this residue in seedling's quality, showing a disproportion between the two variables, once growth was not followed by the foliar mass gain (Sousa et al, 2015). We must emphasize that while less the value of the H/MSPA ratio, more rustic will be the seedling and therefore greater will be its chance to survive in the field.…”

Substratos orgânicos formulados a partir de adições de solo a compostos orgânicos de diferentesorigens podem interferir no crescimento inicial e qualidade de mudas de espécies arbóreas. Avaliamos ainteração entre tipos e proporções de compostos orgânicos (CO) na nodulação e produção de mudas deClitoria fairchildiana. O experimento foi disposto em delineamento inteiramente casualizado com fatorial2 x 5, dois tipos de CO [COP (de poda de árvore) e CLU (de lixo urbano)] e cinco proporções de compostoorgânico:solo (0:100; 20:80; 40:60; 60:40; 80:20; v:v), com cinco repetições. Avaliaram-se: a nodulaçãonatural (NN), altura da planta (H), diâmetro do caule (DC), número de folhas (NF) e comprimento da raiz(CR), massa seca da parte aérea (MSPA), massa seca de raízes (MSR), massa seca total (MST), relaçõesentre altura sobre massa seca da parte aérea (H/MSPA), massa seca da parte aérea sobre massa seca da raiz(MSPA/MSR) e o Índice de Qualidade de Dickson (IQD). As proporções de CO influenciaram H, NF, DC,CR, MSPA, MSR, MST, H/MSPA, MSPA/MSR e IQD das mudas de C. fairchildiana. Houve interação entreos tipos e proporções de CO para H, MSPA, MSR, MST, H/MSPA, IQD e CR. Substratos constituídos porproporções de COP ou de CLU adicionados a Latossolo reduzem o crescimento inicial e a nodulação naturaldas mudas. O substrato indicado para o crescimento inicial de mudas de C. fairchildiana pode ser constituídoapenas por Latossolo Amarelo.

“…We can observe the highest accumulation of total biomass (DMT) in the T4 treatment (sand + cattle manure), which can be attributed to the chemical fertility of the substrate associated with the porosity of the sand, which allowed for good aeration, water retention and the continuous availability of nutrients for plants, minimizing the probability of nutritional deficiencies during the period of seedling formation. Such behavior was also verified for Sesbania virgata grown with organic compost made of bovine manure [31]. In the case of the T7 treatment, as it is only a mixture of sand and vegetable ash, it should be noted that in this case there is an absence of nitrogen in the substrate (lost due to volatilization in the burning of the plant material), which may explain the low performance in this treatment in the most of the measured variables.…”

The Moringa oleifera Lam. it is a perennial, arboreal species, rapidly growing, resistant to drought and with leaves, flowers and edible fruits. With this research the objective to evaluate the effect of different substrates in the emergence and development of seedlings of Moringa. The experiment was carried out at the Plant Ecology Laboratory of the Department of Phytotechnics and Environmental Sciences, at the Center for Agricultural Sciences, at the Federal University of Paraíba. The experimental desing was completely randomized, with eight treatments T1= sand washed (control), T2= sand + coconut fiber, T3= sand + rice bark, T4= sand + bovine manure, T5= sand + pine powder, T6= sand + chicken manure, T7= sand + vegetable ash and T8= quail, with four repetitions of 25 seeds totaling 100 seeds for each treatment. The substrates were used in proportion 3:1, and these proportions were determined in terms of weight and all the sieved substrates, arranged in 6 cm x 29.5 cm x 45.5 cm trays, with an approximate capacity of 7 liters of substrate. The following parameters were evaluated: the emergence percentage, first count, emergence speed index, seedling height, plant height, root length, number of leaves, dry leaf biomass, stalk, root and total. The germination and initial development of M. oleífera seedlings were satisfactory in sand and favored when fibrous materials of vegetable origin (coconut fiber, rice bark or pine powder) or bovine manure were added to the substrate. The addition of manure sand from birds (chicken and quails) and vegetable ash did not favor the substrate for germination of Moringa oleifera Lam. seeds. Contribution/Originality: In search of alternatives to reduce costs and maintain the yield and quality of the production of Moringa oleifera Lam, we tested the use of alternative natural substrates. The influence of using different substrate alternatives on the nutritional quality of this crop is an economically viable and beneficial to the environment.Popularly known as moringa (Moringa oleifera Lam.), It is a species belonging to the Moringaceae family [1]. It is an arboreal vegetable that reaches 8 to 12 meters in height, has slight growth, the ability to resist in poor soils,

“…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.
