Fluazifop-P, applied in the spring or fall and pronamide, applied in the fall only, reduced quackgrass infestation in established alfalfa and increased the dry matter yield of alfalfa. Herbicides did not improve alfalfa in vitro digestibility or crude protein content. Average residues of fluazifop-P in alfalfa treated with rates of 0.25 or 0.5 kg ai ha–1, were 0.1 mg kg–1when harvested 280 d after application, and 0.06 mg kg–1when harvested 295 d after application. Average residues in alfalfa harvested 41 and 55 d after application were 0.13 mg kg–1and 0.1 mg kg–1, respectively, with a 0.25 kg ha–1treatment and 0.19 mg kg–1and 0.05 mg kg–1, respectively, with a 0.5 kg ha–1treatment.

Row Width

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.

ABSTRACT The present study aimed to assess the influence of pruning on the starch yield and nutritional value of the aerial parts of industry- purpose cassava clones adapted to the Cerrado region of Central Brazil. Four elite clones were submitted to either total shoot pruning or no pruning at 12 months after planting, in a randomized complete block design with three replications. Plants were evaluated eighteen months after planting. Clone 330/09 presented the highest root yield with and without pruning, and also higher starch yield, green and dry mass yields, and crude protein yield of aerial parts without pruning. In plants that were pruned, clones 117/09 and 359/09 stood out, with higher yields of the crude protein content of the aerial part and a higher in vitro digestibility of the dry matter. These clones are therefore an option when using the aerial parts of cassava in animal feed. Total pruning at 12 months of age significantly increased the crude protein content and in vitro digestibility of the dry matter of the aerial parts, improving its nutritional value. Pruning did, however, reduce the starch yield of the roots and the total yields of the roots and aerial parts.

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 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.

Pure stands of alfalfa, bromegrass, orchardgrass and timothy, each represented by two varieties differing in maturity and/or plant type, were harvested weekly during their first crop growth in 1961, 1962, and 1963.All forages consistently increased in dry matter yield until approximately the early-seed stage. Differences in rate of growth, development and dry matter yield occurred between and within forages and years. Bromegrass, the earliest to start growth, and timothy had similar final yields of dry matter, alfalfa was intermediate and orchardgrass was lowest.At the heading stage in the grasses and at the very-first-flower stage in alfalfa, all species had stored 70% of their dry matter but 82% of their in vitro-digestible dry matter (IVD) yield. Unlike dry matter, IVD yields increased slowly after early June.The crude protein content and yield were considerably lower in the grasses than in alfalfa. Varietal yield differences within a species were small except for orchardgrass. At the suggested harvest time, alfalfa had stored 87% of its maximum crude protein yield, and the grasses, 96%.

Trifolium Resupinatum

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.

The purpose of the research was to study the effect of planting time on the formation of productivity of Hungarian sainfoin when grown for green forage. Methods are field, laboratory, statistical, correlation and regression relationships. Research results. It is established that under uneven humidity and high temperature regime in the year of sowing, Hungarian sainfoin formed two yields under spring planting date and one yield under summer planting date. In the second and third years of growth, no significant effect of the planting date on the stages of organogenesis of Hungarian sainfoin was found, where the maturity of the herbage was reached simultaneously. Productivity of Hungarian sainfoin was only conditioned by hydrothermal conditions, where the yield of green mass averaged 45.9—49.6 t/ha with crude protein content of 1.58—1.73 t/ha. At the same time, the highest dry matter yield of 10.25 t/ha and crude protein of 1.73 t/ha was provided by agrophytocenosis when sown on April 12. The productivity index of Hungarian sainfoin in the first year of life was determined, where the highest indicator was obtained during the early spring sowing period (29.04) – 7.85 kg/ha of dry matter per 1 hour of light day, whereas for the recommended summer sowing period was 1.13 kg/ha, or 6.9 times lower. The correlation equation between dry matter output, duration of daylight and the sum of precipitation from full shoots to the beginning of flowering in the first year of life is described. It is found that with increase of precipitation by 1 mm the dry matter output increases by 1.53 % and there is a tendency increase with increasing the length of daylight by 1 minute. Conclusions. It has been established that on gray forest soils of the right-bank Forest-Steppe, over two years of intensive use of the grass stand, regardless of hydrothermal conditions, Hungarian saifoin provided a stable forage productivity when sown in spring. Thus, dry matter yield was 9.38—10.25 t/ha with crude protein content of 1.58—1.73 t/ha. In particular, as for summer planting date, July 20 appeared to be the most effective planting date, which provided dry matter yield of 9.78 t/ha with crude protein content of 1.61 t/ha.

The Mean

SummaryThe crude protein content and in vitro dry-matter digestibility (I.V.D.) of leaves and stems of Andropogon gayanus, grouped into four different age categories, were measured at weekly intervals during the secondhalf of the 1968 wet season. The crude protein content of all categories of leaf and stem rose to a maximumat ear emergence; significant reductions occurred thereafter, especiallyin the younger categories of leaf and stem. At any point in time the younger leaves and stems contained significantly more crude protein than the older leaves and stems.Although the mean crude protein content of each stem category was significantly lower than the corresponding leaf category, the young, elongating stems had a significantly higher crude protein content than the older, mature leaves at the time of ear emergence.The mean I.V.D. of all leaf and stem categories was highest at the start of the recording period. At ear emergence the I.V.D. of the young elongating stems was at least as high as the mature leaves. After ear emergence the I.V.D. of the stems fell more rapidly than the leaves.The results support the principle of cutting at ear emergence to achieve maximum yields of digestible nutrients.

Yield And Quality

At Kyabram, Victoria, the effects of growth stage at cutting on dry matter (DM) yield and quality of lucerne was determined during the warm season haymaking period for cultivars with contrasting winter dormancy characteristics. Growth stages at cutting were pre-flower bud, flower-bud, 10% bloom and full bloom. Cultivars were winter non-dormant CUF 101 and Pioneer Brand 572, semi-winter dormant Pioneer Brand 581 and winter dormant Pioneer Brand 545. Cultivar responses or interactions between cultivar and growth stage at cutting were not significant (P>0.05) for dry matter yield, crude protein or in vitro digestibility. Cutting of the pre-flower bud stage, compared with cutting at the 10% bloom stage, reduced DM yield by 18% (16.4 v. 13.5 t/ha), but increased crude protein content of the lucerne from 19.3 to 24%. The total protein yield per hectare was not affected by cutting stages from pre-flower bud stage to 10% bloom. Cutting lucerne at the flower bud stage rather than at 10% bloom gave increased protein content and digestibility with only a moderate yield decline. However, more frequent cutting was unsatisfactory as it decreased the density of the stand and increased the proportion of weeds and so could not be recommended.
