Sod production and the effects of liquid organo-mineral fertilizers and thickness of sod

Abstract

ABSTRACT:Nitrogen fertilization and an appropriate cutting thickness can result in firmer sod that can be handled in less time with greater turfgrass regrowth during the subsequent cycle.This experiment was conducted on a sod production farm located in Capela do Alto, in the state of Sao Paulo, Brazil. The soil was a dystrophic Rhodic Hapludox (Oxisol) with a medium texture.The experiment had two statistical designs; the initial design was randomized blocks with seven treatments and four replicates. Treatments were five doses of liquid organo-mineral fertilizer (OMF) corresponding to 0, 100, 200, 300 and 400 kg ha -1 of nitrogen (N) with supplementation of phosphorous (P) and potassium (K) as well as two control treatments -one with 300 kg ha-1 of N as OMF and the other with 300 kg ha -1 of N-urea + P and K. At harvest, the adopted design was a split-plot type with four replicates in a 7 × 3 factorial arrangement with seven treatments as the main plot and three sod cutting heights (9, 16 and 22 mm) as subplots. Nitrogen doses in the form of OMF influenced the percentage of ground cover (PGC) by turfgrass in both cycles.The N dose of 300 kg ha -1 formed the sod more quickly and provided the largest mass of roots and stolons and the highest sod tensile strength. The thinnest sod samples had faster regrowth and provided higher PGCs.

Lawn irrigation with domestic wastewater by subsurface drip or sprinkling

“…Considering the angular coefficient of the generated equations, each 1% of the applied irrigation depth would provide increases of 1.2, 1.9, 1.2 in RCC at 125, 145 and 190 DAS, respectively (Table 7). Increasing RCC values in response to application of N-containing products was also observed by Gazola et al (2016), Lima et al (2018) and Mota et al (2019). Lima et al (2012) indicated, for bermudagrass cv.…”

“…The lawn was taller in the plots irrigated with DW, both by drip irrigation and sprinkling, when compared with the grass irrigated with TW. This greater plant growth can be attributed to the presence of ions, mainly N, found in larger amounts in DW (average 56 mg L -1 ), as N is considered the main nutrient responsible for shoot growth, in lawns (Gazola et al, 2016, Lima et al, 2018, Mota et al, 2019.…”

Development of Paspalum accession plugs for turfgrass establishment

“…Esmeralda (Zoysia japonica Steud. ), a stoloniferous and rhizomatous species, is the most used species in Brazilian (Lima et al, 2018). The plug size was standardized around 10 cm (Figure 1) including the rhizomes or stolons and the aerial part.…”
