“…Under our experimental conditions, the concentration of N in both of the organs analysed was not affected by the treatments tested. In 2-year-old plants of the same species treated with 225 mg L -1 N, higher concentrations of N in leaves, pseudobulbs, and roots (15, 10, and 25 g kg -1 , respectively) were observed (Tejeda-Sartorius et al, 2018), as compared to our results (9, 6, and 7 g kg -1 N in leaves, pseudobulbs, and roots, respectively) in 3-year-old plants. In the present study, our fertilizer (Peters® Professional 30-10-10) contained urea as the main source of N. Thus, from the 30% of total N supplied by our fertilizer, 24.8% was in the form of urea, so that the NH4 + :NO3ratio was high.…”

The effects of three fertilization methods (FM) using the Peters Professional® 30N-10P-10K water soluble fertilizer were analyzed: fertilization in irrigation water (FIW), foliar fertilization (FF), and their combination (FIW + FF), as well as two substrate particle sizes (SuPS): larger particle size (LPS) and smaller particle size (SPS), on the growth and macronutrient status of Laelia anceps subsp. anceps (Orchidaceae). A 3 × 2 factorial experiment was established. Aerial and root growth, dry weight and concentration of macronutrients N, P, K, Ca, and Mg in leaves, pseudobulbs, and roots were all evaluated. The interaction of the study factors resulted in a greater number of leaves, while by simple effects, greater leaf area, number of pseudobulbs, root volume, and dry matter of leaves and roots were obtained, when FIW and LPS were used. With FF, greater growth in root volume was observed. There were no differences in the concentration of N in the growth organs analyzed, but due to the interaction of factors, a higher concentration of P, K, Mg, and S was observed in roots, mainly with FIW + FF and SPS; although for P, there was a higher concentration in FIW and LPS. In the case of SPS, the concentrations of K and S were higher in leaves, and in pseudobulbs P, K, Ca, Mg, and S were higher. The results showed that there are positive effects on plant growth when FIW and LPS are used, while higher concentrations of nutrients in leaves, pseudobulbs and mainly in roots are observed when using SPS.

“…For DLL, there was statistical difference between substrates for plants fertilized at 30 and 45 DAT. Hoshino et al (2016a), when studying organic fertilization in the development of orchid Cattlianthe "Chocolate drop", stated that Bokashi increases the number of pseudobulbs and leaves, and, consequently, their development and diameters; this was also observed in Laelia hybrid plants with use of this nutrition (Tejeda-Satorius et al, 2018).…”

Vegetative development and flowering of Encyclia hybrid based on fertilization and substrate

et al. 2021

Due to the fact that the western region of Paraná is considered subtropical, with high temperatures in the summer, the hybrids of Encyclia are commercialized by the beauty of its flowers and durability. However, there are no studies involving potted plants, substrate types and fertilizers, as well as hybrids, for the genus Encyclia. Thus, the objective of this work was to evaluate the vegetative development and flowering of Encyclia based on fertilization and substrate. The experiment was conducted in a commercial orchard, from January to September/2017. The seedlings remained in a protected environment, with 50% shading. The experimental design was randomized blocks, in a 4 x 5 factorial scheme (substrates x fertilization intervals), with 4 replicates per treatment, and 4 pots per replicate. The lot chosen was sowed in vitro, with the hybrid Encyclia “Kropp” x E. atropurpurea. After five months of the last fertilization, the evaluations related to vegetative development and flowering were carried out. Substrates based on sphagnum presented better results in flowering. Organic fertilizations with Bokashi at 45 days after transplant (DAT) favor flowering and vegetative development of the Encyclia hybrid, which occurs in pots containing sphagnum-based substrates and with organic fertilizers above 60 DAT.

“…In addition, plant height and leaf area increased significantly with increasing doses of nitrogen regardless of the source used, but the pseudobulb length, root number, and dry matter production of plants only increased when urea was used as a nitrogen source. Tejeda-Sartorius et al [23] demonstrated that the use of commercial biofertilizers in combination with mineral fertilizers (30N-10P-10K) is recommended in order to increase the availability and uptake of Ca, Mg, and Cu nutrients in young Laelia anceps (Lindl.) plants.…”

Oncidium are grown worldwide and play important economic roles. The objective of this study was to investigate the pseudobulb growth and flowering characteristics of the two Oncidesa Gower Ramsey cultivars, ‘Honey Angel (HA)’ and ‘Golden Star (GS)’, cultivated under 3 kinds of fertilizer treatments in response to 40% light intensity (LI-40) and 30% light intensity (LI-30, as control) photosynthetic photon flux density over a 5-month period. The conventional-fertilizer (CF) treatment, as a control, consisted of a liquid manure solution of N:K = 1:1.12, mixed with 7.8% N, 0.8% P2O5, 0.3% K2O, and 57.3% of organic matter that was foliage-applied to plants twice weekly. The stage-fertilizer (SF) treatment consisted of N:P:K = 1:1:5 foliage-applied to plants in an unsheathing pseudobulb stage until reaching inflorescence, followed by N:P:K = 1:1:1 application until the end of the experiment. The fortnight-fertilizer (FF) treatment consisted of N:P:K = 1:1:5 and N:P:K = 1:1:1 with interval-rotate foliage-application to plants weekly until the end of the experiment. Pseudobulb length (PL), pseudobulb major axis (PW), and pseudobulb minor axis (PT), and inflorescence length (FL), number of pedicel (FB), and floret numbers (FN) per plant were recorded and calculated from two months after pseudobulb maturity until the end of the five-month experimental period. The GS variety significantly increased PL when treated with CF and FF compared to HA, and GS treated with CF under LI-30 exhibited the longest PL at 81.65 mm. PW increased as LI increased under FF treatment, and the largest PW was observed in GS treated with FF under LI-40. A maximal and significant increase in PT occurred in LI-40 compared to LI-30 under the CF treatment. GS had a significantly higher FL compared to HA treated with CF, and the longest FL was detected in GS under LI-30. HA had a significantly higher FB and FN under LI-40 than under LI-30, and the highest number of FB and FN in HA occurred when it was treated with CF and SF, respectively. Precision management of fertilization treatments in response to LI can maximize pseudobulb growth, development, and flowering quality in Oncidesa species.
