The Difference

SUMMARYYields and quality of herbage from a cocksfoot/white clover sward were compared over a 3-year period when cut repeatedly with a reeiprocating-blade mower to either 1 in or 2½ in from ground level or with a cylinder lawnmower to 1 in from ground level. The comparisons were made under two frequencies of cutting, namely five times per season at the ‘grazing’ stage, or three times at the ‘silage’ stage.Cutting to 1 in from ground level with the reciprocating-blade mower gave a greater total yield of dry matter and crude protein than did cutting to 2½ in with the same mower in the first year, when the average dry-matter yield difference was 10·7 %, but no significant differences were recorded in subsequent years. It is suggested that the difference noted in the first year was due mainly to the harvesting at the first cut in the season of the layer of herbage between 1 and 2½ in from ground level, and not to any differential effects of the treatments on stem and leaf development of the cocksfoot.Cutting to 1 in from ground level with the lawnmower gave smaller dry-matter yields than did cutting to 1 in with the reciprocating-blade mower at both stages of growth in the first year, but a slightly greater yield at the ‘grazing’ stage in the third year. The type of mower used affected the botanical composition of the sward.

The effects of cultivars, date and rate of seeding on the yield and quality of alfalfa (Medicago sativa L.) seeded at the end of summer and harvested the year after was studied from 1971 to 1975 on a Kamouraska clay. Seeding in early August gave the best results; seeding should not be carried out after mid-August. Differences between cultivars were more important on the third than on the first cut. Aftergrowth was an important factor on yield during the first year of harvest. Seeding rate did not always affect the yield, but the 6,7 kg/ha rate yielded less than the 13,4 kg/ha rate at the first cut and when the cuts were summed. The combined effects of the three factors studied indicates the importance of the seeding date on the height, cover and yield of alfalfa. Digestibility and crude protein content of the dry matter were affected more by seeding dates than by cultivars. The effect of cultivars on quality was variable and seeding rates had no effect. The variation in forage quality may be attributed to a difference in maturity of the plant at harvest, rather than only to the factors studied.Key words: Medicago sativa L., cultivar, date, rate, yield, quality

The trial was conducted at the Centro de Producción Agrícola of ICfA in Cuyuta, Escuintla-Guatemala in order to generate information on the yield and quality of edible mulberry (Morus sp.) roughage treatments consisted of three harvest frequencies (6; 9 and 12 weeks and three fertilization levels of nitrogen (0.40 and 80 kg/ha). A complete randomized block experimental design, with a factorial arrangement (3x3) was used. The cutting height was 0.3 m above the ground level with two sequencies: from August 2nd to September 13 th and from September 13th to December 6th, 1990. In both cases, the 12 week frequency cutting and 80 kg of N were superior to the others (P<=0.01), yielding 6.87 and 6.15 t/ha of dry matter respectively. The yields at 9 weeks were statistically higher than those at 6 weeks. The highest protein percentage of the whole plant, leaves and stalks were produced at 6 weeks. The dry matter digestibility values in vitro showed little variability among treatments, with averages for whole plants, leaves and stalks of 65, 91 and 41 %, respectively. The preceeding data suggests that the mulberry has an excellent potential as a balanced supplement (protein and energy) for dual purpose cattle on the Southern coast of Guatemala.

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 &ldquo;site&rdquo; related to altitude could not be observed. While the energy concentrations decreased with advancing winter and partly reached the values below 6 MJ&nbsp;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. &nbsp;

1. The effects of two heights of cutting—down to either 1 in. or 2–2½ in. from ground level—on herbage yields were studied for five seasons with a perennial rye-grass-white clover mixture and for three seasons with a timothy-white clover mixture. Superimposed on these height-of-cutting treatments were treatments simulating strip grazing with and without a back-fence, and also three fertilizer nitrogen treatments.2. Over the 5-year period the rye-grass mixture consistently gave greater dry-matter and crude-protein yields of herbage when cut to 1 in. than it did when cut to 2–2½ in. from ground level, the mean dry-matter yield difference being 34%. The decline in the total yield per season with increasing age of the grass sward was similar under both heights of cutting.3. The effects of the height-of-cutting treatments on the timothy mixture were similar to those noted on the rye-grass mixture in the first three seasons of the experiment, but in the third year the beneficial effects of close cutting were much reduced. It is suggested that this resulted from the rest period between cuts being insufficient for timothy to recover fully from the close defoliation.4. The effects of the height-of-cutting treatments on the botanical composition of the sward were slight, particularly on plots of the rye-grass mixture.5. Possible factors leading to the observed effects of the height-of-cutting treatments are discussed with reference to the results of other workers and to the results from a preliminary study of the differential effects of the treatments on stem and leaf formation in perennial rye-grass.6. A simulation of strip grazing with and without a back-fence showed that the herbage yields from both seeds mixtures under both height-of-cutting treatments were considerably reduced by the removal of the regrowth which could take place in the absence of a back-fence.7. The effects of delaying the first nitrogenoua fertilizer application of the season noted in an earlier experiment were fully confirmed in this experiment.

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.

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.

A field experiment was conducted at Main Forage Research Station, Anand Agricultural University, Anand during rabi-2019-20 to study the effect of nitrogen levels on yield and quality of multi cut oat cultivars with aim to find out nitrogen levels on green fodder yield and quality of oat. There were total four varieties (V1: OL 1874, V2: JO-05-304, V3: UPO 212 and V4: RO 19) and four levels of nitrogen (N1: 35 kg N/ha, N2: 70 kg N/ha, N3: 105 kg N/ha and N4: 140 kg N/ha) was tested. Experiment was laid out in split plot design with three replications. Experiments results revealed that significantly the highest green fodder yield was reported in RO 19 (V4) treatment, while average plant height and average number of tiller per meter row length were reported in V1: OL 1874 and V2: JO 05-304 treatment, respectively. Average plant height, Green fodder yield, average dry matter, average crude protein, total crude protein yield and dry matter yield were found highest by application of 140 kg N/ha. Average tiller per meter row length was higher in N4 (140 kg N/ha) and average dry matter was higher in N1 (35 kg N/ha). Response of nitrogen non-significant in case of average ADF and NDF content.

В статье приведены результаты исследований по изучению влияния минеральных удобрений и куриного помета на продуктивность клубней картофеля отечественной и зарубежной селекции. В исследованиях, проведенных в 2017-2019 гг. на черноземе выщелоченном в условиях Пензенской области, установлено, что при внесении куриного помета и минеральных удобрений повышается урожайность и качество клубней, что непосредственно связано с обеспеченностью растений питательными веществами. Применение куриного помета в дозе 2 т/га позволило повысить общую урожайность клубней исследуемых сортов картофеля на 22,6-29,5, товарных клубней на 24,3-35,5 по сравнению с вариантом без удобрений. Наибольшую урожайность наблюдали на вариантах с совместным применением мочевины в дозе N30 и сульфата калия в дозе К60 и на вариантах с совместным применением аммофоски в дозе N30Р30К30 и сульфата калия в дозе К30. Применение умеренных доз минеральных удобрений и куриного помета в дозе 2 т/га увеличивает не только урожайность клубней картофеля, но и содержание в клубнях сухого вещества, крахмала и нитратов, не превышающих значения ПДК. Совместное применение азотно-калийных и азотно-фосфорно-калийных удобрений с добавлением сульфата калия в дозах К60 и К30 позволяют улучшить качественные показатели клубней по всем изучаемым сортам.The article presents the results of studies on the influence of mineral fertilizers and chicken manure on the productivity of potato tubers of domestic and foreign selection. In the studies conducted in 2017-2019 on leached chernozem under the conditions of the Penza region, it was found that when chicken manure and mineral fertilizers are applied, the yield and quality of tubers increases, which is directly related to the supply of plants with nutrients. The use of chicken manure at a dose of 2 t/ha allowed to increase the total yield of tubers of the studied varieties of potatoes by 22.6-29.5, marketable tubers by 24.3-35.5 compared with the variant without fertilizers. The highest yields were observed in variants with the combined use of carbamide in a dose of N30 and potassium sulfate at a dose K60 and in variants with a combined use of ammophos at a dose N30P30K30 and potassium sulfate at a dose K30.The use of moderate doses of mineral fertilizers and chicken manure at a dose of 2 t/ha increases not only the productivity of potato tubers, but also the content of dry matter, starch and nitrates in the tubers, not exceeding the MAC value. The combined use of nitrogen-potassium and nitrogen-phosphorus-potassium fertilizers with the addition of potassium sulfate at doses of K60 and K30 can improve the quality indicators of tubers for all studied varieties.
