Italian, annual and perennial ryegrasses are the most important grass species cultivated for seed production in the Czech Republic. The straw remaining after seeds threshing can be used as low quality forage, bedding material or as soil amendment. However, there are no comprehensive information concerning grass straw yields and quality in central Europe. The aim of this study was to investigate the Italian (IR) and perennial (PR) ryegrass straw yield and quality. These parameters were measured for two harvest years at two locations. IR did not provide statistically higher straw yield than PR (7.50 and 7.17 t.ha–1 respectively, p = 0.314), but dry matter (DM) content immediatelly after threshing was higher than for PR (0.42 and 0.38 respectively, p = 0.03). IR straw had the same content of ash and hemicellulose (mean 69.8 and 216 g.kg–1 DM, p = 0.22 and 0.57), but less crude protein (64.1 and 81.4 g.kg–1 DM, p = 0.003), more fibre (399 and 382 g.kg–1 DM, p = 0.02), NDF (656 and 629 g.kg–1 DM, p = 0.03) and ADF (442 and 412 g. kg–1 DM, p = 0.000) when compared with PR straw. Most of the parameters were affected by the year (with exception of crude protein) and by location (with exception of yield, DM content, ash and crude protein). There were no differences in mineral nutrient contents between species. The highest values were found in potassium (19.8 g.kg–1 DM) what is comparable with average quality hay. Phosphorus, calcium and magnesium contents (1.42, 2.96 and 1.02 g.kg–1 DM) were substantially lower than in hay. Data concerning ryegrasses straw yield and quality from the USA are comparable with our results and can be used for European conditions.

Yield and quality of herbage seed can be affected by many diseases. In New Zealand the most important diseases of grasses are rusts, especially stem rust on ryegrasses, cocksfoot and timothy; head smut of bromes; and ergot of paspalum. Blind-seed disease is of minor importance on ryegrass at present. Clover yield can be affected by rot, scorch and stem nematode. These diseases and others are discussed in relation to changing farming practices, and disease control measures are suggested.

Soils under intensive and successive cropping with central pivot irrigation tend to present high nutrient contents, especially phosphorus (P), which is a nutrient with a great impact on the yield and quality of agricultural products. Among the rotating crops, the application of high P rates is common in processing tomato, although not supported by research. This work evaluates the effect of phosphate fertilization (0, 200, 400, 600, 800, and 1000 kg ha-1 P2O5) on the yield and quality of industrial tomato ‘Heinz 9553’ grown in a soil with high available P content (145 mg dm-3) resulting of an intensive vegetables cultivation, which have high demand by P. The highest total (127.4 t ha-1) and commercial (108.6 t ha-1) yields were obtained with 413.9 and 384 kg ha-1 P2O5, respectively. The results showed that pH of tomato juice, the percentages of green, red, and commercial fruits were not influenced by the applied P rates. However, nutrient delivery increased the soluble solids content up to 356 kg ha-1 P2O5, which is interesting for tomato processing. After harvesting the fruits, the available soil P content was increased with P supply to the plants. For improvement of commercial yield and soluble solids characteristics, the tomato crop shall be fertilised with P even though the soil has high P content.

Midas marrowstem kale (Brassica oleracea L.) was grown in different row width associations with United 106 corn (Zea maize L.) in two studies and ensiled in different moisture blends with corn stover in another. Highest dry matter yields were obtained where a single row of kale was grown at 30 cm to the side of a corn row. This combination also provided the lowest moisture content feed and the highest in vitro digestibility and crude protein content. Changing the corn row width had no significant effect upon yield, plant height, in vitro digestibility, kale leaf or corn ear content. Blending kale with corn stover to provide a silage of about 70% moisture increased the digestibility and protein content of the feed and provided a silage that kept well in storage.

In addition to the results published in the first communication (Opitz von Boberfeld et al., 2006) this paper presents crude protein, energy (ME) and ergosterol concentrations of autumn saved herbage at different sites in Central Germany, Poland, Hungary and the Czech Republic. Within these sites, the influence of the factors pre-utilisation and winter harvest date was tested over three consecutive years. Related to the different climatic conditions of the sites, crude protein concentrations of the growths pre-utilised in July varied from 149 g/kg in November to 134 g/kg of dry matter (DM) in January. The influence of climatic conditions was different on each location and varied depending on the year. Generally, the consistent effect of the factor “site” related to altitude could not be observed. While the energy concentrations decreased with advancing winter and partly reached the values below 6 MJ ME/kg of DM in January, the ergosterol concentrations increased. The results demonstrate that under Central European conditions autumn saved herbage, pre-utilised in July, could provide adequate quantity and quality for suckler cows until December. Afterwards, the utilisation of preserved forages becomes essential.

Herbage yield increased with elevation from 2200 to 2600 m and then declined until 2800 m. Altitude did not affect herbage fat, acid detergent fibre, calcium or sulphur concentrations, but did influence herbage organic matter, crude protein and phosphorus concentrations. It is recommended that livestock should be rotationally grazed along an altitudinal gradient on Xiaowutai Mountain to meet their dry matter (DM) and nutrients requirements in summer grazing systems.

SUMMARYThe yield and quality of herbage produced by six grasses (perennial ryegrass, cocksfoot, timothy, rough-stalked meadow grass, tall fescue and Italian ryegrass) were examined both without irrigation and under two irrigation regimes. Water was applied according to the potential soil water deficit (potential SWD): the soil was either partially returned to field capacity (FC) after each cut or fully returned to FC whenever the potential SWD reached 25 mm. The swards were cut either at 3 (C3) or 6 (C6) week intervals over a 2 year period.Partial irrigation increased yields by 12–14% in the first year and by 36–58% in the second. Full irrigation produced little more growth than partial irrigation in the first year (maximum SWD, 188 mm) but increased yield by 78–93% in the second, very dry, year (maximum SWD, 311 mm). Under treatment C3 response per unit of water applied was similar with both partial and full irrigation, but under C6 the response was greater with partial (2·86 kg D.M./m3) than with full irrigation (1·79 kg D.M./m3).There were marked differences between the species in their ability to grow under drought conditions in the second year of the experiment. Without irrigation, roughstalked meadow grass and Italian ryegrass did not survive the drought. The performance of tall fescue was markedly superior to both perennial ryegrass and cocksfoot in these conditions. Of the surviving grasses timothy made least growth.

A field experiment was conducted during summer season of 2007 at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum, Shambat, Sudan, to investigate the effect of seed rate and NPK fertilization on yield and quality of Rhodes grass forage (Chloris gayana L. Kunth) cv. Finecut. The treatment consisted of three seed rates (SDR1, SDR2 and SDR3) namely 5, 10 and 15 kg/ha and three NPK fertilizer levels (F0, F1 and F2) namely 0, 120 and 240 kg/ha respectively. NPK fertilizer components were N17 P17 K17. The experiment was laid out in a Factorial CRBD with four replications. The results showed that seed rate significantly increased forage fresh and dry yield. NPK fertilization significantly increased forage fresh and dry yield. Neither seed rate nor NPK fertilization were significantly affected crude protein and fiber content of leaves and stems of Rhodes grass, but the increase in seed rate and fertilizer levels slightly increased crude protein and decreased fiber percentage. Seed rate ×NPK fertilization interaction showed significant effect on crude protein and crude fiber contents. The highest protein percentage obtained under SDR2 (10kg/ha) with highest NPK fertilization level F2 (240 kg/ha), and lowest value obtained under SDR1(5kg/ha) with NPK fertilization F1(120kg/ha) and SDR1(5kg/ha) under control of fertilizer treatment (F0). Regarding crude fiber, highest value obtained under SDR2(10 kg/ha) with NPK fertilization F1 (120kg/ha) and SDR3 (15 kg/ha) under control treatments of fertilization (F0).

Effect On Yield

Objectives of the present study are to determine the variations in forage yield and quality of soybean cultivars. Experiments were conducted in randomized complete blocks design with 3 replications during the growing season of 2016. A total of 10 cultivars were used as the plant material of the experiments (Bravo, A3127, Traksoy, İlksoy, Mersoy, Nova, SA-88, Arısoy, Safir, Atakişi). Cultivars had a significant effect on yield and chemical composition. Results revealed that green herbage yields varied between 826.39 - 1199.17 kg/da, dry hay yields between 247.71 - 357.90 kg/da, crude protein yields between 16.91 - 39.86 kg/da, acid detergent fiber (ADF) ratios between 26.56 - 34.61%, neutral detergent fiber (NDF) ratios between 38.43 - 44.85%, crude ash contents between 7.20 - 11.22%, crude protein contents between 6.66 - 13.53%, dry matter digestibility (DDM) values between 61.94 - 68.21%, dry matter intake (DMI) values between 2.68 - 3.12% and relative feed values (RFV) between 2.68 - 3.12. The results of the study showed that A3127 cultivar was found to be prominent with green herbage yield (1199.17 kg/da) and dry hay yield (357.90 kg/da) and Safir cultivar was found to be prominent with crude protein yield (39.86 kg/da). It was concluded that the soybean cultivars A3127 and Safir could be recommended for hay production.
