In a field experiment, conducted on four different soil types, trace elements cobalt, zinc, manganese, copper, sodium and molybdenum were applied by sprayer to a grass-legume sward in late September in both 1955 and 1956. Treatment differences were evaluated in terms of total dry matter production and by the chemical composition of the plant tissue. The elements applied were detectable in plant tissue, but herbage yields were not affected. Apparently the trace elements in these different soil types were in the range of sufficiency for maximum herbage production.

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.

Morphological characteristics, dry matter production, and nutritional values of winter forage and grains were evaluated. This study was conducted from April 24, 2012 to November 7, 2013 in the Western Paraná State University (UNIOESTE), Marechal Cândido Rondon, Brazil. Pastures under one grazing and non-grazing conditions were evaluated under 120 kg N ha-1 fertilization split into two 60 kg N ha-1 treatments. Two pastures received 40 kg N ha-1 three times. IPR 126 oat, BRS Tarumã wheat, and IPR 111 triticale were the test crops. Topdressing with 40 or 60 kg N ha-1 did not change morphological characteristics until 60 d after sowing. Pastures under non-grazing that received 120 kg N ha-1 treatments were taller than the controls, whereas those under grazing that received 80 or 120 kg N ha-1 presented with higher leaf production than did the controls. Total average dry matter (DM) production in 2012 and 2013 was, respectively, 5,275 kg ha-1 and 6,270 kg ha-1 for oat, 3,166 kg ha-1 and 7,423 kg ha-1 for wheat, and 4,552 kg ha-1 and 7,603 kg ha-1 for triticale. Split N fertilization did not cause differences in the levels of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in the forage. Nevertheless, increases in in vitro dry matter digestibility (IVDMD) were observed in oat and wheat receiving 60 kg N ha-1 during the first graze. IVDMD did not change in oat, wheat, and triticale forages receiving 80 or 120 kg N ha-1 during the second graze. Grazing did not affect the nutritional values of wheat and triticale grains, but reduced those of oat. Therefore, the results of the present study suggest that grazing lengthens the crop cycles, and so allow the staggered sowing of summer crops.

The response of 4 temperate grass species (Lolium perenne cv. Victorian, Thinopyrum ponticum cv. Tyrell, Austrodanthonia richardsonii cv. Taranna, A. bipartita cv. Bunderra) to saline irrigated conditions was evaluated over 4 seasons at Tatura in northern Victoria. This experiment followed earlier research where the salt tolerance of ~20 species of grasses was evaluated in the greenhouse. Field plots were established under non-saline conditions and were irrigated with saline water at 1.6, 2.5, and 4.5 dS/m. Measurements made on these plots included dry-matter production, tissue ion (Na+, Cl–, K+, Mg2+, Ca2+) concentrations, in vitro dry-matter digestibility, root distribution, and soil chemistry. Soil salinity (EC1 : 5) and sodicity (SAR1 : 5) levels peaked at 0.30–0.60 m depth and reached 1.3 dS/m and 9.8, respectively, for the highest saline irrigation treatment. Cumulative plant dry-matter production was lower in T. ponticum compared with the Austrodanthonia species and L. perenne at all salinity levels, but in relative terms there was no difference in the salt tolerance among any of the 4 species (the reduction in dry weight at 4.5 dS/m was 10–15% for all species). Leaf tissue concentrations of Na+ and Cl– were significantly lower in A. richardsonii and A. bipartita compared with T. ponticum and L. perenne, and in vitro dry-matter digestibility tended to be greater in L. perenne under saline conditions than in the other 3 species. This research suggests that the 2 native Austrodanthonia species can be grown under moderately saline conditions—either under saline irrigation or in a dryland discharge area—in environments where perennial ryegrass may also be grown.

This study was conducted in Adami-Tullu Jido-Kombolcha and Arsi Negelle districts, south central Ethiopia. The objectives of the study were to evaluate the interactive effects of grazing management systems and rangeland sites on dry-matter production and chemical composition of herbaceous plants in south central Ethiopia. Data were analyzed using GLM procedure in SPSS 16.0 version, which was used for mean comparisons using post-hoc t-test that can be employed to compare mean differences for enclosure and open-grazed areas. To test the effects of management systems and altitudinal variation on dry-matter production and chemical composition of herbaceous species, mixed model analysis was employed using sample site as a random variable while grazing management systems and altitude were fixed variables. A total of 28 herbaceous species were identified. Of the identified herbaceous species, 20 species were grasses, 2 species were legumes while 6 species were forbs. Among the recorded grass species, some were highly desirable, while others were in the categories of intermediate in terms of desirability and less desirable. We identified the dominant and common grass species that included: Arstida adscensionis, Cenchrus ciliarus, Chloris gayana, Chloris roxburghiana, Bothriochloa insculpta, Eragrostis papposa, Heteropogon contorus, Panicum maximum, Indigofer spinosa, Tephrosia pumila, Sporobolus pyrmidalis, Themeda triandra, B. nigropedata, Ocimum basilicum, Amaranthus dubis, Tribulos terrestris and Achyrantes aspera. The chemical composition of herbaceous plants were analyzed for DM, CP, NDF, ADF, ADL and Ash comparing two grazing management systems and three rangeland sites as patch mosaic units. The results of the present analysis showed that the average CP content in the open-grazed areas was significantly (P<0.05) higher than that of the enclosed areas. The upper and middle rangeland sites displayed significantly (P<0.05) higher CP content for the open-grazed areas than the enclosure management across the study areas. The present findings suggest that the DM, NDF, ADF, ADL and Ash contents of herbaceous species was significantly (P<0.05) lower in the open-grazed areas than in the enclosure management.
