A B S T R A C TThis study assessed the effect of different substrates and addition of nutrient solution on the production of Pochota fendleri seedlings, leaf contents of macro and micronutrients and chlorophyll a and b. The experimental design was completely randomized, in a 3 x 2 factorial scheme, with four replicates. The factors were three substrates, with or without addition of nutrient solution, composing six treatments: (T1) = sand; (T2) = soil; (T3) = sand + soil (1:1); (T4) = sand + nutrient solution; (T5) = soil + nutrient solution; (T6) = sand + soil + nutrient solution. Growth characteristics (height, collar diameter, shoot dry matter, root dry matter, root/shoot ratio and total dry matter) and contents of macro-and micronutrients and chlorophyll a and b were evaluated. The use of nutrient solution reduces the time to obtain seedlings of Pochota fendleri, and it is important for proper growth and quality of seedlings. The sequence of nutritional requirement presented by Pochota fendleri seedlings in three substrates with addition of nutrient solution follows the descending order: macronutrients (N > Ca > K > Mg > P > S) and micronutrients (Fe > Mn > B > Zn > Cu).Solução nutritiva e substratos para produção de mudas de cedro doce (Pochota fendleri) R E S U M OObjetivou-se, neste trabalho, verificar o efeito da adição de solução nutritiva em diferentes substratos na produção de mudas de Pochota fendleri, e seu efeito nos teores de macro e micronutrientes e de clorofilas a e b nas folhas. O delineamento experimental utilizado foi inteiramente casualizado em esquema fatorial 3 x 2, com quatro repetições. Os fatores foram três substratos e adição ou não de solução nutritiva, compondo seis tratamentos: (T1) = areia; (T2) = solo; (T3) = solo + areia (1:1); (T4) = areia + solução nutritiva; (T5) = solo + solução nutritiva; (T6) = solo + areia + solução nutritiva. Foram avaliadas características de crescimento (altura, diâmetro do colo e massa seca da parte aérea e radicular, relação raiz/ parte aérea e massa seca total), além dos teores de macro e micronutrientes e de clorofilas a e b. A utilização de solução nutritiva reduz o tempo para obtenção de mudas de Pochota fendleri e é importante para o crescimento e qualidade das mudas. A sequência de exigência nutricional das mudas nos três substratos com adição de solução nutritiva segue em ordem decrescente: macronutrientes (N > Ca > K > Mg > P > S ) e micronutrientes (Fe > Mn > B > Zn > Cu).

“…The greatest mean values for height and root-collar diameter in plants of Annona cacans Warm. were obtained at the 8 g L -1 dose of CRF ( Figure 1A and B), meeting the recommended and normalized standards for forest seedlings, which should have a diameter of 10 mm to 2 cm at the level of the root collar; a height of 60 cm, measured from the root collar; and be aged from 4 to 7 months from planting (Smiderle and Souza, 2016). The results also suggest that use of the highest dose of CRF under test was enough to supply the nutrient demand of the plants, allowing them to present increasing values, which were greater in comparison to those of the control treatment.…”

The use of controlled-release fertilizers is a promising alternative for supplying nutrients during the initial growth of nursery seedlings. The aim of this study was to verify the effects of different doses of controlled-release fertilizer (CRF) on initial growth and nutritional status in seedlings of Anonna cacans Warm. The seeds were originally sown in a seedbed and then, after initial seedling development, were transplanted into polyethylene bags containing a substrate of washed medium sand, to which different doses of CRF had been added before transplanting. The experimental design was completely randomised, with four treatments, five doses of Osmocote® NPK 19-06-10 formulation (0, 1, 2, 4 and 8 g L -1 of substrate), with four replications, each replication comprising three seedlings (one in each container).Increases in root-collar diameter and plant height were determined throughout the experimental period (6 months) from data collected every 30 days after transplanting. At the end of the experiment the following were evaluated: height, root-collar diameter, N concentration, chlorophyll index, chlorophyll concentration (a, b and total) and leaf area. Root-collar diameter and height showed a positive linear response to increases in the fertilizer dose. From a 4 g L -1 dose of CRF, the nutrient supply added to the substrate of medium sand optimises the initial phase of plant growth and guarantees the adequate nutritional status of Anonna cacans, and can be suggested as a viable technique for use in forest nurseries, and one which results in efficient use of the input material and avoids fertilizer wastage.

“…According to Smiderle and Souza (2016), stem diameter is one of the most important morphological traits to estimate seedling growth after planting in the field. All alternative treatments led to stem diameter values from 43 to 58% higher than that of the control.…”

Using residues generated in agriculture to produce seedlingsis an economically interesting alternative, besides being a way to reduce the environmental impacts caused by their inadequate disposal. This study aimed to evaluate the potential of using coffee chaff (CC) and organic compost (OC) as substrate components for the production of Formosa papaya seedlings and the potential of grape pomace (GP), a vitiviniculture residue, in the composition of substrates for the production of okra and zucchini seedlings. We carried out two trials in a completely randomized design (CRD): the first had seven treatments and six replicates: T0: 100% commercial substrate Bioplant® (CS); from T1 to T6: increasing proportions of CC and decreasing of CC: 10/90; 20/80; 30/70; 40/60; 50/50 e 60/40%. The second had six treatments and six replicates, with increasing proportions of GP and decreasing proportions of CS: 0/100; 10/90; 20/80; 30/70; 40/60 and 50/50%.In the first trial we evaluated the number of leaves, root length, seedling height, stem diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI) at 59 days after sowing.The second trialwas performed at 12 and 18 DAS and we analyzed the number of leaves, plant height, root length, collar diameter, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index (DQI). Variables that met the assumptions of normality and homoscedasticity were subjected to Dunnett’s test. The substrate composed of coffee chaff and organic compost has a high potential to be used as an alternative substrate due to promote better quality of papaya seedlings compared to the commercial substrate. Alternative substrate containing 60% coffee chaff and 40% organic compost is recommended for the production of Formosa papaya seedlings in tubes. The grape pomace (GP) has a high potential to be used as component in substrate for the production of okra and zucchini seedlings compared to the commercial substrate (CS) only. Alternative substrate composed of 50% GP and 50% CS is recommended for the production of zucchini seedlings, while substrate composed of 10% GP and 90% CS is recommended for the production of okra seedlings.
