The potential of Lupinus exaltatus, L. mexicanus, and L. rotundiflorus foliage as green manure in terms of total dry matter production and nitrogen (N) content was evaluated. This study was conducted from November 2015 to March 2016 in Zapopan Jalisco, México. The experiment was established in a randomized 3×7 block factorial design. Whole plants, leaves and stems were collected at different periods after sowing and analyzed for N and dry matter content. At the start of the experimental period, a slow growth was observed, based on dry matter production; however, at 93 days after sowing, both biomass and total N increased in the aerial part. The lowest and highest N content was found in L. rotundiflorus (1.2 to 4.0%).The highest dry matter and N accumulated in whole plants were found in L. exaltatus at 169 days after sowing with 21,605 and 410.6 kg ha-1, respectively.

The objectives in this work were to study the association between the morphological and productive characteristics in Pennisetum sp. clones, and to identify the morphological characteristics responsible for the productivity in Pennisetum cp. clones. The canonical correlations were evaluated and the path analysis was made from the simple genotypic correlation matrix between the morphological and productive characteristics of eight Pennisetum sp. clones (Taiwan A-146 2.37, Taiwan A-146 2.27, Taiwan-146 2.114, Merker México MX 6.31, Mott, HV-241, Elefante B and IRI-381). The canonical correlations were significant at 1% probability by the Chi-square test. The first pair of canonic factors, with correlation of 0.9999, related the plants with the highest dry matter content to plants with lower leaf area indexes, light perception and leaf angle. The second pair of canonic factors, with correlation of 0.9999, related the plants with the highest dry matter production to the plants with higher basal tiller density, height, and low green leaf number per tiller. The results of the path analysis indicated that the light interception is determinant in dry matter content expression of Pennisetum sp. clones, while the basal tiller density and plant height are responsible for dry matter production in these clones.

The objective was to evaluate sowing density influence on hydroponic corn fodder bromatological composition, harvested in different ages raised on grass mix substrate. The experimental design used was completely randomized with six replications for each treatment, using 2.0 m² plots (1.0 x 2.0 m). The densities were distributed into factorial array (4x4), consisting in four sowing densities (1.0, 1.5, 2.0 and 2.5 kg m-²) and four cutting ages (10, 15, 20 and 25 days). The dry matter content (DMC) and production (DMP) and crude protein (CP), acid detergent fiber (ADF), Fiber neutral detergent (FND) and ethereal extract (EE) were analyzed each cutting age. In terms of DMP (kg m-²), EE (%) and DMC (kg m-²), it is recommended to use the density 1.0 kg m-² with cutting age of 25 days. Regarding CP (%) the best result was at 15 days of cut and density 2.5 kg m-² and the values for FND (%) and ADF (%) were higher at 25 days at 2.0 kg density 2,0 kg m-². The choice of both best harvesting age and density will depend on what is desired of the nutritional forage (CP, EE, NDF, ADF, DMC and DMP) as well its destination, since very close values were found in all analyzes, regardless of density and age of harvest analyzed.

1. Two experiments were conducted in a lowtemperature cabinet. In the first experiment three grass varieties (two North African fescues and S 22 Italian rye-grass) were subjected to two cutting treatments (herbage cut from 8 in. to 2 in. and from 4 in. to 1 in.). Dry-matter production, dry-matter content and tiller number were recorded from plots of 9, 16 or 25 plants. The second experiment, a uniformity trial, was planted with a uniform population of a North African fescue. The optimum plot size and shape within the cabinet, and the optimum arrangement of blocks, was determined using a Titan autocode programme.2. Treatment and variety differences could be detected using very small plots. For the material and apparatus used, an 18-plant plot was the optimum size.

Silage Additives

The efficient production and utilisation of home-grown feed is considered one of the key factors that underpins the profitability of dairy systems in southern Australia. The use of winter forage cereals for grazing and silage provides an opportunity to achieve high dry matter yields over the winter and spring period. However, questions remain on the nutritive value of whole-crop cereal silage and its subsequent use as a production feed in livestock systems. This experiment examined the nutritive characteristics of winter wheat, triticale, forage peas and bi-crops of cereals and peas sown at different proportions, cut for silage at the soft dough growth stage of the cereals and their subsequent silage nutritive characteristics and fermentation patterns when ensiled with and without bacterial inoculant additives over 2 consecutive years. The estimated metabolisable energy (ME) (Year 1) and crude protein (CP) (Years 1 and 2) concentrations of the forage pea before and after ensiling were higher (P < 0.05) than all other forages in both years. The cereal–pea mixes had similar estimated ME values to the cereal monocultures both before harvesting and as silage, although there were significant improvements in CP concentration at the higher rates of pea inclusion. All resultant silages were well fermented as indicated by low pH, low proportions of total N as ammonia-N and high lactic acid concentrations. There were marked differences in the proportions of lactic acid and acetic acid in the pea silages between years and this is likely a result of dry matter content differences at ensiling. There was no effect of silage additives on resultant silage nutritive characteristics or fermentation parameters indicating that well fermented silage can be achieved without the additional cost of using a silage additive. This study has indicated that forage peas can be ensiled with winter cereals and produce silages that have higher CP concentrations than cereal silage but with similar fermentation parameters. Furthermore, this experiment has highlighted the potential of growing a monoculture of forage peas for ensiling with the resulting silage having higher estimated ME and CP concentrations.

The effects of aluminium (0, 0.5, 1.0, and 2.0 p.p.m.) on dry matter production and subsequent short-term uptake and translocation of phosphorus in whole plants, and on the uptake of phosphorus by excised roots, of six tropical pasture legumes were ascertained. Macroptilium lathyroides, Desrnodiurn uncinaturn, Lotononis bainesii, and Stylosanthes hurnilis were tolerant species in terms of effects on dry matter production. Glycine wightii was a sensitive species and Medicago sativa a very sensitive one. In the whole plant study, plants were grown in Solution culture with a phosphorus concentration of 2 p.p.m., under the above aluminium treatments. Aluminium increased the subsequent uptake of phosphorus (tops+roots) in all species (phosphorus substrate concentration 1 x 10-5M labelled with 32P, 1 and 3 hr uptake periods). Phosphorus uptake in the tops of the four tolerant species was increased by aluminium treatment, and in the two sensitive species it uas reduced. In both the absence and presence of applied aluminium, L. bainesii was the most efficient species per unit weight of root tissue in sorbing total phosphorus, and in addition had the highest efficiency of translocation of phosphorus from roots to tops. S. humilis was also an efficient species. In the excised root study, addition of aluminium to the solution enhanced the sorption of phosphorus by all species. The enhancement was greater in a relatively strong phosphorus solution (2 x 10-4 M) than in a dilute solution (1 x 10-4). The sorption of phosphorus by excised roots of S. humilis from dilute and relatively strong phosphorus substrates was greater than that of other species, both in the absence and presence of added aluminium. L. bainesii was omitted from the excised root experiments.

ABSTRACTSeventy-two British Friesian cows, with a mean calving date of 21 January, were used in a 3 × 2 factorial design experiment to assess the effects of the interval between harvest and wilting on the value of grass silage for milk production. Three regrowth intervals of 5, 7 and 9 weeks were used with each material ensiled both unwilted and after wilting to a dry-matter content of approximately 450g/kg. The six silages were offered ad libitum in addition to 7·6 kg concentrates per day, from day 8 of lactation until 13 April, with a mean experimental period of 67·5 days. The mean intakes of silage dry matter were 11·2, 9·8 and 8·7 kg/day for the 5-, 7 and 9-week regrowth intervals respectively and 9·6 and 10·2kg/day for the unwilted and wilted silages respectively. Regrowth interval significantly affected milk yield with mean yields of 24·7, 24·2 and 22·5 (s.e. 047) kg/day being obtained for the 5-, 7- and 9-week intervals respectively. Wilting significantly depressed milk yield with mean yields of 24·8 and 227 (s.e. 0·39) kg/day being recorded with the unwilted and wilted materials respectively. Live weight at the end of the experiment was not significantly affected by any of the treatments but the rate of live-weight loss, calculated by linear regression over the experiment, and loss in body condition score both significantly increased with increasing regrowth interval. Wilting had no effect on live weight or body condition. Increasing the regrowth interval also significantly reduced the solids-not-fat and protein contents of the milk produced during the final week of the experiment but no other significant effects were recorded on milk composition.Blood analysis data are presented: blood urea was the only component affected by the treatments and decreased significantly as regrowth interval increased.

The effect of N and P fertilization on the dry matter content, concentration of nutrients (N, P, K, Ca and Mg) and their intake by the plant, production characteristics (achene yields, head diameter, 1000-seed weight, oil content and oil production) and the content of fatty acids (palmitic, stearic, palmitooleic, oleic, linoleic and linolenic) was evaluated in the one-year pot trial with sunflower (Helianthus an­nuus, L.). Nitrogen application had a positive effect on dry matter production and increased N intake by plants as early as the beginning of vegetation (4th true leaf). The effect of P on dry matter production was not markedly evident until the later growth stage (10th true leaf). At the end of the vegetation period the weight of plants of variants fertilised with N only and variants where P was applied evened out. Achene yields, head diameters, 1000-seed weight, oil content and oil production increased statistically significantly after N application. Of all the monitored characteristics the increased level of P in the soil affected only the 1000-seed weight. The application of both nutrients did not significantly change the content of fatty acids.

Abstract This study evaluated dry matter yield and nutritional characteristics of different oat genotypes (Avena spp.) for ensiling. Treatments consisted of genotypes of white oat IPR 126 (Avena sativa), black oat Cabocla IPR and Agrocoxilha (Avena strigosa), and BRS Madrugada and BRS Centauro (Avena vertis). Oats were harvested at the phenological stage of milk/dough grain. The design was a completely randomized block scheme, with five treatments and three replications per treatment. The IPR Cabocla genotype showed the highest dry matter content (before and after silo opening) and in vitro dry matter digestibility of fresh forage. No differences were observed for in vitro dry matter digestibility and dry matter losses among silages. The highest silage digestible dry matter yield (kg ha-1) was observed for the BRS Centauro genotype. Thus, despite the better nutritional quality presented by the IPR Cabocla genotype before ensiling, BRS Centauro genotype presented a higher yield of digestible dry matter per hectare.

Initial Results

Recent increases in the value of gold have led to renewed interest in gold mining - particularly by the dredging of the river flats bordering West Coast rivers. In any future licensing of such dredging, the rehabilitation of the "destroyed" land will be a major consideration. Nitrogen is the main nutrient limiting the growth of radiata pine on the gold dredge tailings; this paper outlines initial results of an exploratory legume-fertilizer trial on levelled tailings in the Taramakau River valley. Twelve legume species were grown with and without superphosphate (+ MO, Mg and K). Tree lucerne (Cytisus proliferus) , Russell lupin (Lupinus polyphyllus) and yellow tree lupin (L. arboreus) grew well without the application of fertilizer but the pasture legumes had substantially increased dry matter production where P was added - in white clover (Trifolium repens) dry matter production was increased from 5.4 to 8.9 t/ha; and total N was 180 and 310 kg N/ha. Tree nutrition and growth were greatly improved by association with a vigorous legume species, In addition, the presence of legumes improved the appearance of the tailings and with a pasture species grazing potential was created
