Phleum Pratense L

An experiment was set up to determine the effect of time and rate of nitrogen fertilization and stage of growth at first cut on yield and digestibility of dry matter and protein content of two timothy (Phleum pratense L.) cultivars, at each of two cuts, No difference in yield or chemical composition was found between cultivars. Highest yields and crude protein contents were measured at rates of nitrogen fertilizer of 112 and 224 kg/ha. Higher yield and protein content were obtained with NH4NO3 applied totally or in split applications in the spring than with urea in the fall. Dry matter digestibility (DDM) was not affected by nitrogen at rates of 56, 112 and 224 kg/ha. First cut was taken at two different stages of growth, and the second cut was taken on the same day in all the plots. At anthesis, yields were higher than at the head stage but DDM and protein content were lower. The opposite was found at the second cut. Except in 1973, total dry matter yield was not affected by the stage of growth at first cut.

Five timothy (Phleum pratense L.) cultivars, Clair, Champ, Milton, Climax and Bounty, were harvested at first flower stage during 2 consecutive years and in the regrowth for 1 yr. The forages were each offered as hay to 15 young rams to evaluate voluntary intake. Five animals were used to determine initial harvest dry matter digestibility. The cultivars varied significantly in voluntary intake at first flower stage. The highest intake (g kg−0.75 d−1) averaged for the years was obtained in the early cultivar Champ (65.9), which was 10% more than that of the medium-late cultivar Climax. The cultivars did not differ significantly in dry matter digestibility. In the regrowth, the relative intakes of the cultivars were essentially reversed from that of the initial harvest. The voluntary intake was substantially higher but the differences among forages were less marked. Climax regrowth voluntary intake was higher (P < 0.05) than all cultivars, except Bounty. A 15% range in digestible dry matter intake was present among cultivars. The ranking of the culivars for digestible dry matter was different than for dry matter yield.

Phleum Pratense L

Timothy (Phleum pratense L.) was grown in pots under controlled conditions. Solutions of 2-chloroethylphosphonic acid (Ethrel) at seven concentrations were sprayed on different plants at six stages of growth. Three cuts were taken on treated plants. Ethrel treatments increased tiller number at each cut. Dry matter yield was significantly decreased by applications of Ethrel at the first cut. Total dry matter yield of the three cuts was the same for all treatments, indicating that yields of the second and third cuts made up yield losses of the first one. Ethrel applications decreased the height of plants at the first cut only. The stage of growth, at the time of Ethrel treatments, also affected results but in a less well-defined manner than did the concentrations.

A 3-yr study on the stages of growth of timothy (Phleum pratense L.) at harvest showed that the dry matter yields increased, in the spring growth, with advance in maturity. The highest annual yield was obtained, however, when the first cut was taken at the bloom stage. The percentage of crude protein, fat and ash decreased and that of crude fibre increased with the age of the plant. The Ca, P, K, Mg, Na, Zn and Cu contents declined with maturity while the elements Mn, Al, Fe and B did not vary significantly. The food reserves in the lower stem internodes were low at the vegetative stage in the spring (11.7% of DM), but raised rapidly up to the bloom stage (33.9%).

Wild ecotypes of Festuca rubra L. (four accessions), Poa pratensis L. (three accessions ) and Phleum pratense L. (three accessions) originating from Central Slovakia were investigated. Dry matter production, qualitative traits as well as mineral content were studied under identical soilclimatic conditions in a three-cut system. Yield potential of wild ecotypes of Festuca rubra L. coming from mountain regions was significantly lower (P < 0.01) when compared to Festuca rubra L. cultivar Levočská. In contrast, as a consequence of low variability, the dry matter yield of Phleum pratense L. wild ecotypes originating from higher altitudes was comparable to the dry matter yields of Festuca rubra L. cultivar Levočská. There were not noted any considerable differences found in the content of crude protein, fibre or mineral substances between the wild ecotypes and the cultivars. All accessions showed consistent patterns in seasonal distribution with the highest dry matter yield at the first cut and with the lowest one at the third cut. In general, concentration of crude protein and fibre did not vary considerably among cultivars and wild ecotypes at all species under uniform growing conditions.

Abstract This study highlights the effect of drought and ambient temperature on performance and herbage quality of legume monocultures and grass-legume mixtures. In a field experiment, the total dry matter yield, seasonal pattern of dry matter yield distribution, content of crude protein and crude fibre of monocultures of red clover and alfalfa and grass-legume mixtures were investigated during two consecutive dry years (2011-2012). Alfalfa cultivars Kamila and Tereza grown as monocultures or as mixtures with Festulolium braunii (cultivar Achilles) outperformed the red clover cultivars Fresko and Veles and provided a well-balanced total and seasonal dry matter yield during both years. Across all experimental years, crude protein content was significantly higher at alfalfa monocultures and mixture when compared with clover monocultures (P < 0.05). However, considerable lower content of crude fibre at clover monocultures in comparison with alfalfa ones was found. Responses of nutritive parameters of both legume species to weather variables were different. Crude protein content in red clover was independent of rainfall and temperature. In contrast, the crude fibre content correlated with temperature whereby the alfalfa monocultures showed stronger correlations (P < 0.05) than red clover monocultures.

The influence of the improved drainage broadbed and furrow (BBF), as opposed to the traditional flat seedbed over the growing season on the dry matter yield and nutritive value of Avena sativa, Vigna unguiculata, Lablab purpureus, Vida dasycarpa, Trifolium steudneri and Sesbania sesban were studied on Vertisol. Up to 7 t/ha dry matter yield was recorded for Avena sativa and Lablab purpureus when planted on Vertisols with improved drainage. Dry matter yield of forage crops also increased with advance in stage of maturity or subsequent harvests. On both improved and traditional flat seedbed methods, the chemical analysis of forage crops showed similar declines in crude protein content and in vitro dry matter digestibility (IVDMD) levels as the maturity of forage crops progressed.

The research was carried out in the Eastern Mediterranean Agricultural Research Institute-Hacı Ali location with 4 replications according to the randomized block trial design in 2013-2014. 13 public and 1 private sector maize variety were used as material in the trials. According to the results of the analysis, it was determined that the maize varieties examined showed statistically significant differences in plant properties, dry grass and silage quality. Average plant height, number of leaves, leaf ratio, stem diameter, number of cob, stem ratio, cob ratio and green grass yield were 249.9 cm, 12.97 plant/piece, 19.24%, 22.08 mm, 0.93 plant/unit, 38.40% and 4,251.57 kg/da respectively. According to the analysis, it was observed that the average crude protein content, ADF ratio, NDF ratio, crude ash content, digestible dry matter ratio, crude protein yield, dry matter rate, dry matter yield and hay yield were 8.80%, 34.91%, 59.7%, 7.2%, 61.7%, 993.9 kg/ha, 29.4%, 11,640 kg/ha 12,570 kg/ha in dry grass, respectively. For the silage of varieties, the average crude protein content, ADF ratio, NDF ratio, pH, digestible dry matter rate, dry matter ratio, crude protein yield and Fleig score were 8.22%, 29.27%, 50.48%, 3.57, 66.1%, 28.14%, 926 kg/ha and 118.35, respectively. Burak, Sasa 1 and Ada 334 genotypes performed better in terms of green yield per hectare (53,650, 50,290 and 45,630 kg/ha) and dry matter yield (14,710, 12,810 and 12,410 kg/ha). These varieties can be recommended to producers as silage maize varieties under second crop conditions in Çukurova region of Turkey.

In a field experiment the development of dry matter yield and forage quality of the catch crop Vicia sativa L. compared with Trifolium resupinatum L. was investigated and the suitability for cultivation in a mixture with Lolium multiflorum ssp. gaudinii (Parl.) Schinz et Keller was tested. The legumes and mixtures sowed in early July or August, respectively, were harvested at different dates from early September until late October/early November. The sowing date had the greatest impact on dry matter yield, crude protein content and net energy for lactation (= NEL). Vicia sativa yielded more dry matter than Trifolium resupinatum, especially at low temperatures and under short-day conditions. At late sowing Vicia sativa should be preferred to Trifolium resupinatum due to a better stability of yield. Vicia sativa had a&nbsp;higher crude protein content but a lower NEL than Trifolium resupinatum. In a mixture with Lolium multiflorum the differences in energy concentration between late sowed legumes were less distinct. In view of NEL, Trifolium resupinatum is superior at early sowing, whereas late sowed mixtures of Vicia sativa and Lolium multiflorum might enable it to feed fresh forage of acceptable quality until early November and in that way to save it for winter feeding and eliminate expensive sources of crude protein.
