Luminosity levels and substrates composition on Bermuda Grass development

Abstract

Turfgrass is a fundamental part in sports fields’ composition. Some aspects should be taken into account in the choosing species process, such as turfgrass use (trampling tolerance), turfgrass management, physical-chemical soil conditions and shade tolerance. With accomplishment of sporting events in Brazil, there was requirement for football arenas reform and modernization. Among architecture alterations, coverings implantation was noticed, resulting luminosity reduction affecting turfgrass development. Therefore, the objective of this work was to evaluate the influence of luminosity and substrates on Bermuda grass (Cynodon dactylon x C. transvaalensis) development. The experiment was conducted in a 5 x 4 factorial scheme (substrates x luminosities), in completely randomized design with 20 treatments and 3 replicates. The substrates were: S1 = Soil, S2 = Soil + sand (2:1), S3 = Soil + organic matter (1:1), S4 = Soil + organic matter + sand (2:1:1) and S5 = organic matter + sand (3:1), in four luminosity conditions: full sun, 30%, 50% and 80% of shading for six months. We evaluated substrates fertility composition, solar radiation, grass height and fresh and dry mass. Shading interfered on Bermuda grass development, which tolerates intermediate shading (30% and 50%). Substrates containing the highest levels of organic matter submitted to shading had impaired turfgrass performance.

Aesthetic and sensory quality of Emerald grass (Zoysia japonica) as a function of substrate cultivation and mineral fertilization

“…According to Santos et al (2019), substrates based on organic matter are able to retain more water and nutrients and thus increase the CEC and consequently the development of the turfgrass, providing greater increases in plant biomass. Experiments where substrates based on organic compost showed the best results have already been observed by Santos and Castilho (2015) in Emerald grass, Amaral et al (2019) in bermuda grass (Cynodon spp.) and Dias et al (2018) in carpet grass (Axonopus spp).…”

“…Brazilian turfgrass are installed without having an ideal preparation of the land, mainly in clay soils, which end up hindering the development of the turfgrass, especially when it is not properly managed (Mateus et al, 2017;Santos e Castilho, 2018b). Therefore, the use of organic materials is essential to improve the development of the species (Santos and Castilho, 2015;Dias et al, 2018;Amaral et al, 2019;Santos et al, 2019).…”

Light Levels Influence on Development and Leaves Reflectance Index of Imperial Zoysia Grass / Influência De Níveis De Luz No Desenvolvimento E Índice De Refletância Das Folhas De Grama Esmeralda Imperial

“…Another interesting point of view to grass growth is the necessity to have the lawn cut to maintain aesthetic and its objective. Therefore, slower growth is advantageous for not be necessary many cuts and enhance maintenance costs (Amaral et al, 2019). However, it is important to note the colour of grass when submitted to shading.…”

Influence of irrigation frequency and nitrogen concentration on Tifway 419 bermudagrass in Brazil

“…This hybrid has a rhizomatous and stoloniferous growth habit, which provides high trampling resistance. It has narrow leaves with intense green color and fine texture, providing softness to Bermudagrass, providing consistent ball rolls on the field and reducing the impact of the players (Godoy et al, 2012;Christians et al, 2016;Amaral et al, 2019).…”
