Chen, CP; Othman, O
Malaysian Agricultural Research and Development Institute; Serdang; Selangor; Malaysia

MARDI (Malaysian Agricultural Research and Development Institute) Research Bulletin 12 (1): 21-37 (1984)

Abstract:
Under the closed canopy of oil palm with mean light transmissions of 15.8 - 5.71% daylight, 8 tropical legumes were evaluated for their general agronomic performance, plant chemical composition and persistence with three cutting frequencies of 4, 8 and 12 months. All legumes declined in yield when cutting frequency was relaxed from 4 to 12 months except Desmodium heterocarpon (syn.: Desmodium ovalifolium) which increased by almost double in DM yield when cut at 8-month as compared to 4-month cutting. Desmodium heterocarpon which was characterized by slow plant establishment and low plant mineral status had the highest root weight, nodules per plant and bigger leaf area to produce the highest DM yield (l 970 kg/ha/year) and nitrogen content (34 kg/ha/year). Although showing constantly higher plant mineral contents and fast plant establishment, Calopogonium caeruleum and Centrosema pubescens, achieved only 29% and 20% DM, respectively, compared to Desmodium heterocarpon. Both species were able to establish good root weight to sustain moderate growth and to achieve plant survival of 36.1% and 38.3%, respectively. Although Desmodium heterophyllum and Stylosanthes guianensis cv. Endeavour and Cook recorded larger leaf sizes ranging from 3.3, 2.6 and 2.8 times larger than the normal, they produced negligible yields. Calopogonium mucunoides and Macroptilium atropurpureum cv. Siratro deteriorated immediately after sward establishment under critical light environment.

Agrivita 15 (1): 39-44 (1992)

Abstract:
Biomass production and performance of several species of leguminous cover crops were compared on acid soils in N. Lampung, S. Sumatra, Indonesia. Long-lived perennial species Calopogonium caeruleum, Calopogonium mucunoides, and Centrosema pubescens, which have a well-branched root system in deeper soil layers, gave a biomass production of about 5 Mg/ha over a 6 months growth period, with an N-contribution to the soil of about 100-200 kg/ha. The velvet bean, Mucuna pruriens var. utilis, had the fastest establishment, but it has a shallow root system on this soil. It is well nodulated and produced a biomass of about 2 Mg/ha, with an N-contribution to the soil of about 70 kg/ha in a 3 months period.

Effects of leguminous cover crops on subsequent maize and soybean crops on an ultisol in Lampung


Utomo, WH; Sitompul, SM; Van Noordwijk, M
Faculty of Agriculture; Brawijaya University; Malang; Indonesia

Agrivita 15 (1): 44-53 (1992)

Abstract:
The inclusion of leguminous species as cover crops in a crop rotation is supposed to increase the sustainability of food crop production systems in the humid tropics. In a long term soil fertility experiment, growth and yield of maize and soybean were recorded in a rotational system with six species of cover crops. The leguminous cover crops involved were Mucuna pruriens var. utilis, Calopogonium mucunoides, Centrosema pubescens, Calopogonium caeruleum, Crotalaria juncea, Pueraria phaseoloides, and Flemingia congesta. As a control, fallow weeds (mainly grasses) were included. A crop rotation was followed by cover crops (6 months) -- maize-maize or soybean-cover crop (3 months) -- maize-maize, both with or without a supply of 60 kg N/ha. Grain yields, plant biomass and several soil characteristics were measured. The use of leguminous cover crops had a beneficial effect on the grain yield of maize relative to that of fallow weeds. In most cases, better results were obtained from cover crops grown for 6 than for 3 months. Apparently replacement of cover crops with soybean for 3 months could not substitute the positive role of the cover crops when a good cover crop had been present, and additional maize grain yield of about 1 Mg/ha could be obtained. A simple calculation showed that all species, except Crotalaria, contributed an equivalent of about 50 kg/ha of N fertilizer to the subsequent maize crop. A positive effect of leguminous cover crops was observed only in the first year on the grain yield of soybean with the use of Centrosema and Crotalaria. No significant effect was observed on soil nitrogen and carbon content after two years. Soil water content was increased and penetration resistance was lowered by the presence of Mucuna and Pueraria/Flemingia in the crop rotation.

Research Report; Purwokerto, Faculty of Animal Husbandry, Jenderal Soedirman University, 1995; 74 p

Abstract:
An experiment on the rehabilitation of degraded land was conducted at Gunung Tugel, Purwokerto. A Split Plot on a Randomized Block Design was used in this experiment. The main plot was three species of legumes, i.e. L1 (Calopogonium pubescens), L2 (Pueraria javanica), and L3 (Calopogonium mucunoides). The subplot was the level of rhizobial inoculation, i.e. I0 (without inoculation), I1 (2.5 g inoculant/100 g seeds), I2 (5.0 g inoculant/100 g seeds) and I3 (7.5 g inoculant/100 g seeds). There were 3 replicates in each treatment combination. The results of statistical analysis showed that the species of legumes gave a significant effect (P<0.05) on the weight of fresh forage, and it gave a highly significant effect (P<0.01) on the water content of the forage and on the nodule weight. However, the levels of inoculation did not show any significant effect (P<0.05) on the weight of fresh forage as well as on the weight of fresh nodules. The highest fresh forage production was obtained from L2 (Pueraria javanica) which was inoculated with 5.0 g inoculant/100 g seeds, namely 3.37 kg/6 square meters. The highest dry matter content was obtained from L1 (Calopogonium pubescens) which was inoculated with 5.0 g inoculant/100 g seeds, namely 28.37%. The highest nodule weight was from L1 (Calopogonium pubescens) which was inoculated with 7.5 g inoculant/100 g seeds, namely 4.92 g/3 tufts of plantation. Meanwhile the highest absorbed nitrogen was obtained from L2 (Pueraria javanica) which was inoculated with 5.0 g inoculant/100 g seeds, namely 117.5 g/6 square meters.

Agricultural Research and Development Branch; Philippine Coconut Authority; Diliman; Quezon City

PCA Annual Report; Diliman; Quezon City: Agricultural Research Branch; Philippine Coconut Authority; 1977, p 133-137

Abstract:
Replacement of undergrowth vegetation from a previously 'cogon' infested coconut area to a fully covercropped area was found to be effectively carried out by overseeding Calopogonium mucunoides at the rate of 25 kg/ha. The technique involved the initial spraying of the weed with glyphosate at a concentration of 0.41% and broadcasting the seeds two weeks after. The complete replacement took only 3 months. Results of the trial, however, deserves further studies to: a) introduce modifications in the technique, and b) determine suitability of the technique in other weed situations.

Limiting factors in the management of oil palm estates on peat soils
Faktor pembatas pengelolaan perkebunan kelapa sawit pada lahan gambut

Chan, F; Lubis, AU
Buletin Pusat Penelitian Perkebunan Marihat [Bulletin of the Marihat Research Center for Estate Crops] 13 (1): 46-63 (1993)

Abstract:
In 1991, the area of oil palm estates in Indonesia reached 1.310.996 ha which were spreaded in 16 provinces, and the climatic conditions and soil types were generally uncomplicated. Recently, development of oil palm estates in Indonesia was aimed at utilization of complicated areas such as tidal swamp areas or peat soils. In peat soil utilization, especially for plant cultivation, some problems either technical, economical, social or environmental will be faced. The problems could be bad drainage and water flooding, surface decrease, wrinkled characteristics, soil acidity and availability of N, P, K, Ca nutrients and some other limiting micro nutrients. As the implication of these problems, more palms are grown at slight tilt, difficult and expensive drainage is built and low production potential. From the experience, it showed that good drainage system, appropriate fertilizer and cultural techniques could solve the problems. But there are some factors that still limit the production or cultivation of oil palm in peat soils.

State of the art assessment: weed management in coconut


Abad, RG
Philippine Journal of Coconut Studies 10 (2): 24-27 (1985)

Abstract:
Weed management in coconut involves nursery and field situations. In the latter, the management covers both monocrop (coconut) and intercrop of multicrop set-ups. Some technologies for the aforestated weed situations area available, ranging from hand-wedding, chemical control, cover-cropping or combinations of these. Application of these technologies should, however, be based on flexible frameworks with economic interest as the prime consideration. Research areas suggested are: effect of weeds on coconut yield, search for drought-resistant or tolerant covercrops, possible role of weeds as alternate hosts of coconut pests and diseases (or its vectors) and biological control of weeds.

Evapotranspirasi dari beberapa jenis tanaman bawah

Pudjiharta, A
Buletin Penelitian Hutan [Forest Research Bulletin] (562): 1-15 (1994)

Abstract:
A study of the evapotranspiration, percolation and run-off by some undergrowth species was carried out at Janlapa, Bogor, West Java at 100 m altitude. The undergrowth species were Pueraria javanica, Calopogonium mucunoides and Flemingia macrophylla (Synonym: Flemingia congesta) as well as those of three species mixture. There were six lysimeters with the size of 2 m x 1.5 m x 1 m which have been used in this study during 1990/1991. It was revealed from the rain-gauge data that the total annual rainfall of the location during the observation period was 3092 mm. The relative humidity was 81.3% and temperature was 27 °C on the average. The precipitation values resulted from Pueraria javanica were 49.31% through evapotranspiration, 16,47% through percolation and 34.22% through run-off. Under Calopogonium mucunoides those figures were 55.76%, 7.61% and 36.63%, respectively. Meanwhile, under Flemingia macrophylla the figures were 53.72%, 6.48% an 39.80%, respectively. In the case of Pueraria javanica and Calopogonium mucunoides mixture, the values were 64.03%, 15.56% and 20.41%, respectively and under the mixture of Calopogonium mucunoides and Flemingia macrophylla were 67.98%, 9.54% and 22.48%, respectively. Based on the observed data, it can be concluded that evapotranspiration by Calopogonium mucunoides > Flemingia macrophylla > Pueraria javanica and evapotranspiration by mixture of Pueraria javanica + Calopogonium mucunoides < Flemingia macrophylla + Calopogonium mucunoides.

Abstract:
Feeding strategies associated with small ruminants involve successful utilization of forages, tree legumes and agro-industrial by-product. Forages generally form the base of most feeding systems and other nutrients are supplemented with the use of tree legumes and by-product. Molasses and mineral blocks manufactured by farmers helped supply deficient minerals and nitrogen. Other feed sources include rubberseed, by product of palm oil factories and agro-industrial by-products. Examples of supplementation systems are given. (Authors' abstract)

Abstract:
Laboratory experiments were conducted using top soil samples taken from Karang Agung Ulu, South Sumatra. One of the objectives of the experiments was to study the effects of the application of lime, organic matter of Calopogonium mucunoides and flooding on acidity and P-uptake. Three dosages of lime (0, 6.91 and 12.71 t/ha) were applied and four dosages of organic matter (0, 3.78, 7.58 and 11.34 t/ha) were applied. Soils water condition was maintained at field capacity and then flooded and incubated for 57 weeks. The chemical characteristics studied were pH H2O and pH KCl 1:2.5, total acidity, exchangable Al, -H, free iron and P-uptake. The lime and its interaction with organic matter decreased acidity and P-uptake. The organic matter did not significantly affect the acidity and P-uptake of the soils. Flooding directed the pH to about 6, did not change potential acidity, but increased P-uptake. (Authors' abstract)

MSc thesis; Edinburgh, University of Edinburgh, 1978; 62p

Abstract:
Hard seed content of three samples of leguminous tropical seeds was assessed at two temperatures (20 and 30 °C). The lower temperature was again observed in the reduction of percentage hard seed (obtained at 20 °C) when stored at 30 °C and 20-30 °C (under 80 % relative humidity for approximately six weeks). This was correlated to the increase in moisture content of the seeds under the same conditions. Scarified seeds experienced a high moisture content throughout the storage period. A subsequent reduction in quality was detected. Hard seeds tolerated the test conditions, but predicted to deteriorate if storage was prolonged.

Forestry and forest products research; Proceedings of the Third Conference, 3-4 October 1995; Vol. 2; Abdul Rashid Ab. Malik et al. (eds); Kuala Lumpur, Forest Research Institute Malaysia, 1996; p 68-77

Abstract:
The degradation of tropical rain forests has been a major issue over recent years. In Malaysia, forest degradation is primarily caused by over-exploitation of the forests through harvesting, degazettement of forest areas and human encroachment. One of the serious negative environmental impacts of harvesting is land degradation which is reflected by increased soil compaction and erosion, decrease in soil fertility and biological degradation of the soil. In response to these environmental phenomena, the relevant government agencies have taken steps such as replanting, rehabilitation and reclamation programmes. The achievements to date are commendable but efforts need to be intensified. Priority should also focus on providing the technical and scientific back-up required for successful replanting programmes. This paper presents some findings on rehabilitation measures carried out by the Universiti Pertanian Malaysia. (Authors' abstract)

Abstract:
One of the efforts to increase dry-land productivity is by dolomite application. The growth condition improved by dolomite would effect both plant growth and weeds. The objectives of this study was to evaluate the effect of dolomite application and pre-emergence herbicide and to predict the benefit farming system of sugarcane plantation by R/C ratio. Material used in this study were sugarcane BW-3065, dolomite, and pre-emergence herbicide. The treatments were arranged by factorial (4x8) in a Strips-Plot Design with three replications. The first factor was dolomite application, consisted of four levels (0, 0.75, 1.50 and 2.25 t/ha). The second factor was weed management systems, consisted of eight levels (without application, conventional management, Diuron 1.5 kg a.e./ha, Diuron 3.0 kg a.e./ha, Ametrin 1.5 kg a.e./ha, Ametrin 3.0 kg a.e/ha, 2, 4-D Amin 1.5 kg a.e./ha, and 2, 4-D Amin 3.0 kg a.e./ha). Weed population dynamic was affected by dolomite on the first six weeks plant age. Ametrin 3.0 kg a.e/ha was able to control weed growth better than that of the other systems of weed management. Additionally, the high value of R/C (2.80) was achieved in sugarcane plantation treated without dolomite application together with Diuron 1.5 kg a.e./ha application. The highest income (3.02 million rupiah) was achieved in sugarcane plantation treated with dolomite 1.5 t.ha together with Ametrin 3.0 kg a.e./ha applications.

Abstract:
Local plant species were screened for Allelophatic Effect using Bioassay Methodologies called Leachate or "Sandwich Method" and the Plant Box Method. Results indicated some probable candidates for allelophaty using agar medium and intact plants as donor plants. Direct allelophatic effects were noted from roots, leaves and other parts of the plant materials. Gliricidia sepium known locally as kakawate and Tamarindus indica or Sampalok are among the promising crops. Other legumes like Seralbizia acle, and Adewanthera intermedia also indicated allelopathy in order crops along with Calopogonium mucunoides, Canavalia ensiformis, Crotalaria spectabilis, Leucaena leucocephala and Mucuna pruriens. Allelopathic activity of Imperata cylindrica and Saccharum spontaneum were also tested on different crops.

Abstract:
Forty matured and growing goats were used in the study to determine the effectiveness of rapid rotational grazing (RRG) in controlling endoparasites of goats. Fecal samples were collected from all experimental animals. Parasites identified were Haemonchus trichostrongylus and Stronggyloides. For growing and matured animals, the parasitic load in terms of egg per gram of the set stocks were higher compared to rotationally grazed stocks. Blood samples were taken to determine the packed cell volume (PCV) of both groups. Higher PCV values for RRG were recorded for both growing and matured animals. Results showed that when egg per gram count was high, lower PCV was noted. Interms of body weight, animals under RRG are slightly heavier compared to set stocks. For growing stock, the difference in weight between RRG and set stocks was 250 grams. On the other hand, matured goats under RRG were heavier than those under set stocks with a difference of 2.8 kilogram. Pasture area nalysis revealed that parasitic load under RRG was greater than under continuous grazing. Isolated cases of diarrhea, pneumonia, pink eye and soremouth were observed in both RRG and set stocks.

CV-CIRRD [Central Visayas Consortium for Integrated Regional Research and Development] Research Journal 1: 23-40 (2002)

Abstract:
An experiment was conducted to evaluate the growth performance of the three cover crops intercropped to Gmelina seedlings. Three cover crops: Calopogonium, Centrosema, and Siratro were examined for their potential for intercropping to Gmelina arborea plantations in terms if number of leaves, total vegetative lengths, and biomass. The result of the experiment showed that Centrosema performed better in terms of number of leaves (545), vine length (73,570 mm) and total biomass (93.38 gms.) compared to Calopogonium and Siratro. Centrosema was not observed to be adversely affected by intercropping of Gmelina seedlings, although Gmelina seedlings showed adverse influence on the total biomass of Calopogonium and root biomass of Sitraro. The data further indicated that Gmelina had high concentration of phenols in the leaf tissues but tend to diminish in concentration to a very low level soil. The soils where Gmelina were grown did not indicate to be influenced by Gmelina in terms of pH, organic matter and phenols. Conducting field trial of the cover crops to different shading intensities was to further test their performance. Basic research on the allelochemicals from Gmelina that may have an influence on the population of undergrowths is needed to provide a better understanding on the development of undergrowths.

Proceedings 12th STARRDEC Regional Symposium on Research and Development Highlights, Rizal State College, Tanay, Rizal, Philippines, 20 August 1999

Abstract:
The study provided initial or benchmark information for the characterization of grasslands in Oriental Mindoro. It identified the major or dominant species community types, extent of coverage, floristic composition and association, palatibility, productive potentials/carrying capacity. It correlates the environmental factors contributing to the ecological development or degradation of the sites. It identified potential grassland species in the province for ecological site indicators and other uses.
