Abstract ‘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.

Abstract A description is provided for Clavibacter XYLI subsp. cynodontis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Cynodon dactylon, where it is limited to the xylem. It also multiplies in the xylem of sugar cane and a Sudan grass-sorghum hybrid when artificially inoculated, but symptoms are not produced (61, 4328). Further host range not yet recorded. DISEASE: Bermuda grass stunting disease. Natural occurrences so far discovered have been in combination with mycoplasma-like organisms thought to cause white leaf and witches' broom symptoms. The presence of the bacterium causes considerably more severe symptoms. The full ecological significance of this bacterium has not yet been evaluated, but a further stress is usually required to produce noticeable symptoms. GEOGRAPHICAL DISTRIBUTION: Taiwan, USA (Florida). TRANSMISSION: So far only mechanical transmission, by artificial inoculation, is known. Cutting blades and possibly grazing animals are likely to spread the infection.

Bahia Grass

Drought responses of turf-type Bermuda grass (Cynodon dactylon (L.) Pers.) and Bahia grass (Paspalum notatum Flugge) in relation to their growth, carbon allocation and accumulation of nonstructural carbohydrates were investigated. Seedlings were exposed to a 20 day terminal drought, followed by 20 day recovery with irrigation. Leaf dry matter was lower in water-stressed plants than control plants by the end of drought, but did not differ in roots. For both species, more carbon was allocated towards roots in response to drought. Total nonstructural carbohydrate (TNC) concentration in shoots was increased in drought-stressed plants of both species. However, root TNC concentrations in Bahia grass were decreased after drought. TNC pool sizes also showed a similar variation, hence correlated with TNC concentrations. Bahia grass maintained a better quality than Bermuda grass after the drought, having recorded a higher aesthetic score, higher relative water content and a lower electrolyte leakage. Results suggest that, both species are considerably tolerant to short-term drought though Bahia grass seems more promising.Int. J. Appl. Sci. Biotechnol. Vol 6(1): 12-16

And Storage

The aim of this study was to characterize the dehydration curve and, gas exchange of bermudagrass (Cynodon dactylon L.) as well as the nutritional value of hay under different conditions of storage. The dehydration curve was evaluated at 7 time point (0, 13, 18, 22, 37, 42, and 44 hours after cutting) until baling, using five replicates. The time 0 (zero) corresponded to the time before cutting, performed at 19:00 hours. The design was completely randomized with measures repeated over time. Gas exchanges was evaluated 0, 14, and 18 hours after cutting, using 10 replicates. The nutritional value of cowpea hay was evaluated in two open and closed environments (SO and CS), three storage times (30, 60, and 90 days), and five replications. Dehydration of hay was carried out for 44 hours, rapid rates of dehydration was observed in the leaves. Gas exchange was more intense before cutting and up to 14 hours after cutting. Crude protein (CP) content was higher at the time of cutting and decrease after storage. The in vitro dry matter digestibility (IVDMD) and neutral detergent fiber (NDF) content showed no variation between the sampling time and storage systems evaluated. Bermuda grass hay presents rapid dehydration and undergoes changes in the bromatological composition with storage time. Internal temperature of the hay bale did not exceed the ambient temperature.
