‘Barazur’ or DiscoveryTM (Cynodon dactylon) is a new variety of Bermuda grass that has slow vertical growth and a bluish-green colour, and the use of sewage sludge in implantation of this species may be an alternative for its sustainable cultivation, without need for chemical fertilizers. Thus, the objective was to evaluate the influence of sewage sludge compound on colour and development of Bermuda grass DiscoveryTM. The experiment was conducted in the field with sod implanted in black plastic containers (volume 8.46 L) filled with soil + sand (1:1) and added different dosages of sludge compost, being: 0 g L -1 (control), 30 g L-1, 60 g L-1 and 120 g L-1. Digital image analysis, fresh and dry leaf mass, Nitrogen leaf and Nitrogen leaf accumulation were evaluated. It was observed that the sewage sludge influenced on turfgrass colouring and development, where 30 g L-1 showed excellent results for colouring with less mass production and N accumulation than the highest dose, showing that this treatment is sufficient for lawn development, without the need of using higher concentrations of compound. It is concluded that the use of composted sewage sludge at a dose of 30 g L-1 is recommended for use in implantation of Bermuda grass DiscoveryTM.

The Brazilian berry (Pliniacauliflora, sin: Myrciariacauliflora Berg), a native tree of the Brazilian Atlantic Forest, called by native people as “Jabuticaba” and cultivated throughout the national territory, is a species produced for consumption in natura, manufacturing liqueurs, ice cream, fermented drinks and juices, jellies, in addition to be used in the pharmaceutical industry for essential oil production. Despite being a tree species, it has been cultivated in pots by those who have little space. Thus, this study aimed to verify substrate compositions with soil in the development of Brazilian berry in full sun and potted. The experimental design was completely randomized, with 3 treatments and 9 replications, being: T1 – Soil + organic compost (1:1); T2 – Soil + sand (1:1); T3 – Soil + sand + organic compost (1:1:1). Chemical and physical properties of substrate mixtures, chlorophyll index and fresh and dry matter of leaves and analysis of leaf macro and micronutrients content were evaluated. Among the evaluated treatments, soil + sand + organic compost (1:1:1) showed favourable results for the evaluated characteristics, while soil + sand (1:1) showed unfavourable results, probably due to the presence of sand in its mixture.

Empire Turf® was the first national cultivar developed, compared to traditional Emerald grass, the Empire is characterized by fast establishment, high erosion control, tolerance to irrigation with non-drinking water, firmer carpets, good drought and salinity tolerance, shading and low demands on soil fertility. However, despite all these desirable characteristics, the development and establishment of the grass will depend on its handling and especially on the substrate in which it is installed. Thus, this study evaluated the development of Empire Turf® conducted on three substrates, with chemical fertilization. The experiment was carried out in containers (volume of 8.5 L) filled with the treatments: T1 - soil; T2 - soil + sand + soil conditioner (1v:1v:1v) and T3 - soil + sand (1v:1v), forming a completely randomized design with three treatments and three repetitions, considering each container as an experimental unit. On March 30, 2019, the first evaluation was carried out, then the treatments received chemical fertilization (NPK+S 13-5-13+14), using 20g of the commercial product diluted in 2L of water, being a single dose per container. After 15 days, in the 2nd evaluation, it was evaluated: foliar chemical analysis, the foliar chlorophyll index (FCI), fresh mass (FM) and dry mass (DM). The results indicated that Empire Turf® presents a rapid response of 15 days, after maintenance fertilization with 10g L-1 of NPK+S (13-5-13+14), having better development when cultivated in soil + sand compound substrate (1v:1v).
