Application of soil amendments and their effect in the growth of heliconia

Abstract

The Heliconias have a great potential as a cut flower and for this reason an adequate management of the crop is important. The objective of this research was the application of soil amendments (Biol and superabsorbent polymers - SAP) and the analysis on their effect in the growth of Heliconia psittacorum cv. Tropica. An experiment was established using a completely randomized design with four treatments and five repetitions: SAP (1 g plant-1), biol (20 mL plant-1) + SAP (1 g plant-1), biol (20 mL plant-1) and one control (without application). A 20 cm rhizome was planted per pot and were evaluated the height of the plant, the number of leaves, the leaf area and the number of shoots were measured. The analysis of variance did not show statistical differences (p ≤ 0.05) between treatments for the variables of the height of the plant, the leaf area and the number of shoots, but statistical differences were found for the variable number of leaves (p ≤ 0.05), and the best treatments were Biol, SAP, and Biol + SAP. With the application of the biol and SAP amendments, it was not possible to increase the plant height, the leaf area and the number of Heliconia shoots. Regarding the application of SAP to the not found significant results in Heliconia, it is expected that treatments with SAP show a better effect in the dry season.

Growth and nutrients content of heliconia under mineral fertilization

“…Golden Torch. The idea that nutrient contents are sometimes determined by biotic and abiotic factors is not excluded; these factors involve temperature, relative humidity, luminosity, genotype, concentration of nutrients in the soil, cultivation and management of the crop (Jarvan and Poldma, 2004).…”

“…During this research, low doses of fertilization were applied based on other researches that state the possibility of the nutrient cycle could reduce the entry of fertilizer, reducing production costs and the environmental risks associated with its unnecessary application (Taniguchi et al, 2016). The application of chemical fertilizer can be considered as a complement to the application of organic fertilizers: in this way satisfy the nutritional requirements of the crop minimizing production costs and reducing the environmental impact (Linares-Gabriel et al, 2017;Linares-Gabriel et al, 2018).…”

Evaluation of hydrogel use in the development of Rapanea ferruginea with water restriction by vibrational Fourier Transform Infrared Spectroscopy (FTIR-UATR)

“…To overcome the difficulties imposed by irrigation in seedling planting, the use of hydrogels is highlighted to supply water-stressed plants (Mudhanganyi et al, 2016. Linares-Gabriel et al, 2018.…”

“…The assessment of hydrogels use in planting is traditionally conducted by monitoring the effect on plant height, mass (leaves and roots) and the soil's retention capacity (Mews et al, 2015;Mudhaganyi et al, 2016;Linares-Gabriel et al, 2018;Felippe et al, 2021). However, little has been studied about the influence on the plants biomolecular development using modern techniques such as Fourier Transform Infrared Spectroscopy (FTIR-UATR), which arises from evaluating atomic vibrations of the molecules that interact with infrared radiation (10 -6 to 10 -3 m) that depends on molecular structure (Pavia et al, 2010).…”

Effect of hydration in vase life of two Heliconia cultivars

“…These changes are mostly more demanding in agricultural activities. Mainly those related to agronomic problems that are generally in the production stage and that have a strong impact on the quality of the commercial stem (Rodrigues et al, 2005;Beckmann-Cavalcante et al, 2011;Linares-Gabriel et al, 2018), for example organic, mineral and organomineral fertilization. Heliconias require shade percentages since they are C 3 plants (Peña-Salamanca et al, 2013), so the shading conditions are indispensable (Souza et al, 2016).…”
