Fluctuation of quantity and quality of forage for ruminant animal is a problem of forage availability in Indonesia. Cover crop under oil palm plantation is potential sources of forage for ruminants but it has not been used effectively. This study was conducted to evaluate nutrients quality and estimated energy available of cover crop in dry season in Pelalawan regency, Riau. Seven years old oil palm plantation was plotted by randomized destructive sampling method. Nutrients composition include proximate, modified van soest fraction and protein association with cell wall (NDICP or ADICP) were analyzed for nutrient quality of cover crop. In vitro true dry matter digestibility (IVTDMD) and estimated energy available in cover crop were calculated from in vitro batch culture daisyII Ankom method. The result showed that cover crop is fresh forage energy feed because it contains more than 40% BK of TDN. Limited nutrient quality of cover crop is high contains of Lignin (22.4%BK). Value of IVTDMD of cover crop is 568.41 g/Kg DM with NDF digestibility 21.05% DM. In conclusion, cover crop under 7 years old oil palm plantation had enough nutrients quality for ruminant but it would be better for complete the data in wet season.Fluktuasi jumlah dan kualitas pakan hijauan untuk ternak ruminanasia adalah salah satu permasalahan penyediaannya di Indonesia.

In 2004&ndash;2009, a small-plot trial was conducted on permanent grassland dominated by Festuca arundinacea Schreb. on the mesohygrophytic site in order to evaluate effects of four levels of nutrition: F<sub>1</sub> = without NPK fertilization, F<sub>2 </sub>= P<sub>30</sub> + K<sub>60</sub>, F<sub>3</sub> = N90 + P<sub>30</sub> + K<sub>60</sub>, F<sub>4</sub> = N<sub>180</sub> + P<sub>30</sub> + K<sub>60</sub> kg/ha), four levels of cutting intensity (I<sub>1</sub>-4, I<sub>2</sub>-3, I<sub>3</sub>-2, early, I<sub>4</sub>-2, late cut) and their interactive influence, i.e. a total of 16 variants on the production of forage dry matter, production of crude protein (CD) and net energy of lactation (NEL) per hectare. The dominant influence of N-nutrition is documented by significant differences in forage dry matter (DM) production between the variants (with the exception of F<sub>1</sub>/F<sub>2</sub>) ranging from 4.41&ndash;4.80 to 8.44&ndash;9.83 t/ha. The effect of different exploitation level on the production is subdominant and no significant differences were found either in the production of forage DM<br />(I<sub>1</sub>-6.41 &ndash; I<sub>2</sub>-6.59 &ndash; I<sub>3</sub>-6.97 &ndash; I<sub>4</sub>-7.50 t/ha) or in the production of nutrients. Management models to be recommended for the given type of sward with respect to the interactive influence, efficacy of forage production and quality are as follows: (a) three cuts/180 kg N + PK/ha with forage suitable for dairy cows; (b) two cuts/90 kg N + PK/ha with forage suitable for cattle breeds kept for meat.

SUMMARYTwo small-grained cereals, Mulga oats and a triticale line, and two legumes, local vetch and local peas, were grown in pure stands and in mixtures at various cereal: legume seed ratios (20:80, 40:60, 60:40 and 80:20) for three successive cropping years, 1981/82 to 1983/84, at Laxia and Dromolaxia, Cyprus, in each year.The cereal pure stands produced, on average, more dry matter, 8·40 t/ha, and more digestible organic matter, 4·12 t/ha, than the legume pure stands, 3·68 and 2·18 t/ha, respectively. On average, total dry matter production decreased linearly as the seed proportion of the legume component in the mixture increased. The proportion of the legume in the harvested material was much lower than expected from the seed ratios. The highest proportion of legume was seen in the mixtures of peas with triticale and ranged from 8·1 to 35·5% at the various sowing rates. Digestibility and crude protein content were highest in the mixtures of triticale and peas.

SUMMARYA range of legumes was evaluated in North-east Thailand for dry season forage production on stored moisture following harvest of the paddy rice crop. Crotalaria juncea (sunnhemp) and Lablab purpureus (lablab) produced the best dry matter yields of 1950 and 2020 kg−1 ha respectively on a cultivated paddy field without further fertilizer. Stored moisture was adequate for these two but growth of other species was poor, especially on plots that received no prior cultivation. In pot experiments, sunnhemp did not respond to either nitrogen application or Rhizobium inoculation, indicating that native strains were effective for nitrogen fixation. Lablab responded to both treatments and gave a 55% dry matter response to inoculation with Rhizobium in the field.

SUMMARYPotassium application appeared to increase dry matter production and yield of oil palms, primarily by increasing leaf area, while nitrogen increased both leaf area and net assimilation rate. Responses to phosphorus and magnesium were harder to interpret. Production of vegetative dry matter attained a fairly constant level at the higher rates of fertilizer application, while the ratio of bunch yield to total dry matter production was little affected by fertilizer treatments. The importance of these results for oil palm breeding, and their possible value in diagnosing fertilizer requirements, are briefly discussed.

The use of cover crops is an important strategy for soil management in the Brazilian Cerrado to improve no-tillage (NT) systems. For this, it is necessary know the potential of cover crop species for biomass production, nutrient cycling, and persistence of residues on the soil surface in soils and climatic conditions of this biome. Thus, the experiment was developed to evaluate the agronomic potential of cover crops cultivated on an Oxisol (Latossolo Amarelo) in the Cerrado of Piau&iacute;, Brazil. The experiment was conducted from January 2015 to July 2016. The experimental design was in randomized blocks with 11 treatments and four replicates. The treatments consisted of single and intercropped cover species. The evaluations were: dry mass production, nutritional composition of the plants, nutrient accumulation by dry mass produced and decomposition rate of the dry mass produced for each treatment. The higher dry matter production was obtained with Crotalaria juncea, Cajanus cajan (cv. IAC-Fava larga), Pennisetum glaucum and Brachiaria ruziziensis. The lower dry matter production was obtained with Mucuna aterrima, and mix of Crotalaria spectabilis + Pennisetum glaucum. The higher nutrients accumulation in the plants occurred for Cajanus cajan (cv. IAC-Fava larga), Crotalaria juncea and Crotalaria spectabilis. The cover plants studied presented good potential for soil conservation, due to the permanence of residues on the surface, except for Mucuna aterrima and Crotalaria spectabilis.

The aim of this study was to evaluate dry matter yield and nutritional value of palisade grass (Brachiaria brizantha cv. Marandu) using nitrogen doses and sprinkler irrigation in two periods of the year, aiming at reducing seasonality of forage production. It was used a randomized block design in a split-plot scheme, with five doses of nitrogen (0, 50, 100, 150, and 200 kg/ha/cut), and the sub-plots were defined by the seasons of the year (wet and dry season), with and without irrigation. During the wet season, in the plots with and without irrigation, doses of 175 and 161 kg/ha/cut promoted the highest dry matter yields. During the dry season, 171 kg ha-1N with irrigation resulted in the highest dry matter yield. During the same season, there was no response to N fertilization in the lack of irrigation. Average contents of CP were 10% with and without irrigation. Contents of neutral detergent fiber decreased with nitrogen doses, while acid detergent fiber was not affected by fertilization. Plots under irrigation reached the maximal acid detergent fiber content at N dose of 60 kg ha-1. Irrigation promotes increase of 15% increase in dry matter yield and it increases contents of neutral detergent fiber.

Thirty-eight introductions of Glycine javanica were established in swards with an associate grass at Lawes and Kumbia in south-eastern Queensland and at 'Lansdown' near Woodstock in northern Queensland. The introductions showed highly significant differences in annual yield and total yield of dry matter. At Lawes there were also significant differences in ease and vigour of establishment, in nitrogen content, and in seasonal yield distribution. Late maturing introductions grew better late in the season when early and mid-season maturity types were either flowering or had flowered. At 'Lansdown' all the introductions tolerated a dry season of 27 weeks in 1965, but failed to survive a dry season of 36 weeks in 1966. At Lawes, the most promising introductions in terms of high yield and strong stolon development in each maturity type were, Tinaroo (late), C.P.I. 26433 (mid-season), Cooper (early), and C.P.I. 27835 (early). At 'Lansdown' C.P.I. 25423 (early) and C.P.I. 25918 (very early) appeared most tolerant of extended dry periods. At Lawes, swards of Cooper (C.P.I. 25702) and green panic grass (Panicum maximum var trichoglume) yielded 7,000 to 8,000 lb of dry matter an acre with a legume content of 50 to 56 per cent in their third, fourth, and fifth seasons. In these swards the dry matter production and legume content showed no signs of declining after the third season.
