“…Similar results as to the low productive efficiency of OrganoAmazon ® are reported for bell pepper seedlings growth (Monteiro Neto et al, 2016) and for two tomato varieties (Monteiro Neto et al, 2018). The authors confirm the lower nutritional contents in this substrate compared to the others, a fact that may also have occurred with the substrate containing only soil.…”

“…In general, two specific substrates, S1 (OrganoAmazon ® ) and S9 (Soil), and those that had sawdust in their composition (S6, S8 and S11) were not efficient for production. The low values found with OrganoAmazon ® , when used separately (S1), may be associated to the low nutritional allocation offered by this substrate (Monteiro Neto et al, 2016), which suggests that the process of production of desert rose seedlings requires substrates with high nutritional content.…”

“…All components of substrates analyzed (OrganoAmazon ® , PuroHumus ® , soil, cattle manure, rice husk in natura and carbonized, except for sawdust) were used by Monteiro Neto et al (2016). Chemical and physical analyses of substrates were extracted from this work, and were used as reference for discussion of the results here obtained, since some substrates, like S1, S2 and S5, were also tested in the mentioned study.…”

“…According to Campanharo et al (2006), the substrate should ensure mechanical support to the root system, ensure water and nutrient supply and provide oxygen and CO 2 transport across the seedlings roots and the external environment. It is worth mentioning that, in addition to the premises required for a good substrate, substrates should be made with materials locally available or near the production location, since they may represent significant increase in production costs, particularly when commercially used or acquired (Monteiro Neto et al, 2016). The desert rose, for being included in the group of species economically profitable only during the last decade, still counts on incipient information on the production system, and on recommendation of substrates for production of seedlings (Colombo et al, 2018b).…”

Adenium obesum (Forssk.) Roem. & Schult., widely known as desert rose, has attracted interest for its esthetic characteristics, which are influenced by the process of seedling production. Using two consecutive experiments installed fully at random, the study aimed at assessing the use of different substrates and hydrogel to produce desert rose seedlings in a protected environment. First, eleven substrates were tested, prepared as follows: OrganoAmazon®; PuroHumus®; soil; rice husk in natura; carbonized rice husk, sawdust and cattle manure. Then, three substrates were tested (S1 - OrganoAmazon® + PuroHumus®; S2 - OrganoAmazon® + PuroHumus® + rice husk in natura and S3 - OrganoAmazon® + PuroHumus® + carbonized rice husk) associated to four hydrogel levels: 0 (daily irrigation), 1, 2 and 3 g L−1 (irrigated on alternate days). Growth variables and quality index of seedlings were assessed. Six substrates (all of them without addition of sawdust and where used in mix) were grouped as those the promoted appropriate growth of seedlings, with height, number of leaves, collar diameter, root length and aerial part biomass superior to 6.5 cm; 13; 12 mm; 7.5 cm and 0.45 g, respectively. The substrate composed of OrganoAmazon® + PuroHumus® (1:1 v/v), when irrigated daily, was the one that favored most the production of quality seedlings. The use of hydrogel in substrates with shifts of irrigation on alternate days did not favor the production of desert rose seedlings.

“…These factors may be connected to the results of the present study as the plants presented somewhat uneven vegetative growth, especially as indicated by the PH/SD value in E2, which also resulted in higher values for several of the variables evaluated (Tables 4 and 5). Similar behavior was also observed in pepper (MONTEIRO NETO et al, 2016) and tomato seedlings (MONTEIRO NETO et al, 2018), indicating that the tested shade nets promote uneven growth of the vegetative parts of a variety of plant species during seedling production.…”

Sugar apple (Annona squamosa L.) is one of the most widely grown member of the Annonaceae family in several regions, but there is still a lack of agronomic data regarding the management of its initial growth stages under Cerrado conditions. The aim of the present study was to evaluate the production of Annona squamosa L. seedlings under different environmental conditions achieved by using shade nets (E1: ChromatiNet® Silver 50%; E2: ChromatiNet® red 50%; E3: ChromatiNet® red 35%; E4: ChromatiNet® Silver 35%) in combination with four different substrates (S1: soil + sand + chicken manure; S2: soil + sand + cattle manure; S3: soil + sand + cattle manure + chicken manure; S4: soil + sand + sheep manure). An experiment was set up using a completely randomized design with treatments in a split-plot arrangement, with four replicates and ten plants per experimental unit. Seedling growth parameters and quality indices were evaluated. The tested environments had higher local temperatures relative to the external environment, which had a negative effect on plant growth. Environment E2 resulted in the highest plant height and dry weight, but led to uneven growth among the evaluated plant parts. The substrate with sheep manure (S4) did not benefit seedling production. The best results for seedling growth and quality were obtained with substrates S2 (soil + sand + cattle manure) and S3 (soil + sand + cattle manure + chicken manure), which are therefore promising for Annona squamosa L. seedling production in the Roraima Cerrado.

El tipo de ambiente y la calidad de los sustratos en la producción de plántulas son esenciales para la producción de plantas productivas bajo condiciones de campo. Con el objetivo de determinar el mejor ambiente y sustrato para la producción de plántulas de dos cultivares de tomate (IPA 06 y Santamélia), dos experimentos, completamente aleatorios y dispuestos en parcelas subdivididas con cinco repeticiones, se llevaron a cabo bajo las condiciones ambientales de Boa Vista, Roraima, Brasil . Los tratamientos consistieron en la asociación entre cinco ambientes (A1 - invernadero, A2 - Chromatinet ® 35% rojo, A3 - Chromatinet ® 50% rojo, A4 - Chromatinet ® 35% plata y A5 - Chromatinet ® 50% plata) y cuatro sustratos S1 - OrganAmazon®; S2 - OrganAmazon® + PureHumus®; S3 - OrganAmazon® + PureHumus® + estiércol del suelo + bovino, y S4- OrganAmazon® + PureHumus® + suelo + estiércol + cascarilla de arroz carbonizada (CRH) en las siguientes variables: número de hojas, altura de la planta, diámetro del tallo, brote seco y la biomasa de la raíz, la relación entre la altura de la planta y el diámetro del tallo de acuerdo con el índice de calidad de las plántulas de colon y Dickson. Los sustratos se hicieron con la adición de PureHumus®, sin presentar CRH (S2 y S3), lo que favoreció el aumento de todas las variables analizadas. Además, el invernadero, especialmente cuando está asociado al sustrato S2, había logrado el mejor ambiente para la producción de plántulas de los dos cultivares de tomate evaluados. Las redes de sombreado fotoconvertidor no fueron eficientes en la producción de plántulas de tomate en condiciones climáticas de Boa Vista, Roraima, Brasil.
