Penelitian ini bertujuan untuk mengkaji pertumbuhan tanaman kacang pinto (Arachis pintoi) yang diberi berbagai jenis dan dosis pupuk anorganik dan organik serta mendapatkan level terbaik berbagai jenis pupuk dalam meningkatkan produktivitas tanaman kacang pinto. Penelitian menggunakan rancangan acak lengkap pola faktorial dua faktor yaitu Faktor pertamajenis pupuk (A= Anorganik; OP= Organik Pabrik; BO= Bioorganik; BS= Biosluri), dan faktor kedua dosis pupuk (D0=tanpa Pupuk; D1= 100 kg Nha-1; D2= 200 kg N ha-1; dan D3= 300 kg Nha-1). Terdapat 16 kombinasi perlakuan, diulang 3 kali sehingga terdapat 48 unit percobaan. Peubah yang diamati meliputi panjang tanaman, jumlah daun, jumlah cabang, diameter batang, berat kering daun, berat kering batang, berat kering total hijauan,luas daun per pot, dan nisbah berat kering daun/batang. Hasil penelitian menunjukkan bahwa tidak terjadi interaksi antara jenis dengan dosis pupuk, semua jenis pupuk organik menghasilkan pertumbuhan tanaman kacang pinto (Arachis pintoi) yang cenderung lebih tinggi dibandingkan pupuk anorganik, dosis pupuk D1 dan D2 cenderung meningkatkan, sedangkan dosis D3 cenderung menurunkan pertumbuhan tanaman kacang pinto. Berdasarkan hasil penelitian dapat disimpulkan bahwa tidak terjadi interaksi antara jenis dengan dosis pupuk, semua jenis pupuk organik menghasilkan pertumbuhan tanaman kacang pinto (Arachis pintoi) yang cenderung lebih baik dibandingkan dengan pupuk anorganik, dan dosis pupuk 120-200 kg Nha-1 cenderung optimal dalam mempengaruhi pertumbuhan tanaman kacang pinto.

INFLUENCE OF CONCENTRATION AND SOAKING TIME OF A. pintoi IN THE COW URINE ON PLANT GROWTH. Cow urine has an auksin a, auksin b, and IAA (hetero auksin) that can stimulate plant roots. The present study was conducted to determine the influence of concentration and soaking time in the cow urine on Arachis pintoi (A. pinto) growth. This study used Completely Randomized Design (CRD) in Factorial arrangement with 2 factors A and B. Factor A= urine concentration: A1 = urine 75% + water 25% and A2; urine 50% + water 50%; and factor B = soaking time: B1 = 1 hour; B2 = 2 hours; Dan, B3 = 3 hours. Treatments were replicated 4 times. Parameters measured were: leaves amount (sheets), plant length (cm), and root weight (g). Research results showed that mean leaves amount ranged from 41,65 to 46,77 sheets, plant length 35,97-36,67 cm, and root weight 1,95-1,72 g. Utilization of cow urine with a different concentration and soaking time gave a non significant different (P>0.05) on leaves amount, plant length, and root weight. It can be concluded that cow urine concentration and soaking time do not effect leaves amount, plant length, and root weight of Arachis pintoi (A. pinto). Key words: Cow urine concentration, Soaking time, A. pintoi.

Full textAbstract:
Tropical grasslands under lowland soils are generally underutilized and the litter of forage legumes may be used to recover these degraded pastures. The objective of this work was to study the dynamics of litter decomposition of Arachis pintoi (pinto peanut), Hyparrhenia rufa (thatching grass) and a mixture of both species in a lowland soil. These treatments were analyzed in three areas: grass monoculture, legume monoculture and legume intercropped with the grass during the dry and wet seasons. Litter bags containing the legume, grass or a mixture of both species were incubated to estimate the decomposition rate and microorganism colonization. Decomposition constants (K) and litter half-lives (T1/2) were estimated by an exponential model whereas number of microorganisms in specific media were determined by plate dilution. The decomposition rate, release of nutrients and microorganisms number, especially bacteria, increased when pinto peanut was added to thatching grass, influenced by favorable lignin/N and C/N ratios in legume litter. When pinto peanut litter was incubated in the grass plots, 50% N and P was released within about 135 days in the dry season and in the wet season, the equivalent release occurred within 20 days. These results indicate that A. pintoi has a great potential for nutrient recycling via litter and can be used to recover degraded areas.

Full textAbstract:
The objectives of this study were to evaluate the effects of different fertilization ratios on the growth of pinto peanut (Arachis pintoi) propagated vegetatively under varying water regimes. The experiment was carried out in a net-house in a completely randomized design with three replicates. The N:P2O5:K2O ratios were applied at six levels: F1 (1:1:1), F2 (1:3:1), F3 (1:1:3), F4 (3:1:1), F5 (3:3:1), and F6 (3:3:3) while soil moisture included three different levels: 30% (W1), 60% (W2), and 100% (W3) field capacity. Water stress conditions were treated from 30-65 days after planting, and then the pots were irrigated to 100% field capacity. The results indicate that drought conditions significantly reduced (P<0.05) the growth of stolons, leaf appearance, number of secondary stolons, and dry matter, while the root/shoot ratio was higher compared to plants under well-watered conditions. There was no significant effect of the fertilization ratios on the number of secondary stolons. Higher-NP and NPK application ratios showed significant influences on the growth of A. pintoi under drought conditions by stimulating stolon lengths and the number of leaves, while the root/shoot ratio was decreased. Higher ratios of single fertilizers (N, P, or K) did not show a consistent effect on the growth of A. pintoi under drought conditions. The results suggest that a higher-NP fertilization ratio stimulates the growth of A. pintoi under both drought and well-irrigated conditions.

Secondary metabolites are important organic metabolites produced by plants. These metabolites include phenolic compounds, which have been of research interest because phenolics are considered an antinutritional factor for ruminants, compromise the bioavailability of nutrients. This study included a chemical composition analysis, an analysis of the condensed tannin content and the identification and quantification of the phenolic compounds present in the following plants cultivated with and without fertilisation: Coastcross-1 grass (G) and the legumes Stylosanthes guianensis cv. Mineirão (MS), Stylosanthes capitata × Stylosanthes macrocephala cv. Campo Grande (CGS), Arachis pintoi cv. Amarillo (AA) and Arachis pintoi cv. Belmonte (AB). High-performance liquid chromatography (HPLC) was used to analyse 13 phenolic compounds. The forage with the best nutritive value was Amarillo pinto peanut. The condensed tannin content was higher in the legumes than that in the grass. Vanillin and o-coumaric, m-coumaric, caffeic and ferulic acid were detected in all the cultivars. The cultivar with the largest variety of phenolic compounds was Coastcross-1 grass. Diversity existed in the occurrence of phenolic compounds, which indicated the presence of condensed tannins in the cultivars and possibly that the diversity does not affect the concentration of these compounds. The AA cultivar was the most interesting alternative for the establishment of pasture intercropped with Coastcross-1 grass.

Full textAbstract:
Legume groundcovers have been promoted for controlling soil erosion in hillside banana plantations in northern New South Wales. An experiment was conducted at Alstonville to determine the effect of an Arachis pintoi (Pinto peanut) groundcover on banana productivity. The Arachis groundcover was slow to establish in the first year, but thereafter grew vigorously. While standing dry matter of groundcover was reduced at closer banana plant spacings, it was always more than adequate to control erosion. After 5.5 years many soil chemical parameters had been significantly affected by the presence of groundcover. Organic carbon concentrations to 30 cm depth were 5.6% greater on the groundcover plots (3.94 v. 3.71%), and total nitrogen was 8.5% greater (0.42 v. 0.39%). Other increases were exchangeable potassium 52%, calcium 26%, magnesium 43%, sodium 23%, electrical conductivity 24%, and pH 0.13 units. Banana leaf nutrient concentrations were not affected. Banana plants with groundcover produced 9% fewer bunches than their bare soil counterparts, with 4% fewer fingers per bunch. By the end of the experiment, fingers on the groundcover treatment were 9% lighter; consequently, the weight of marketable fruit (i.e. >120 g/finger) per bunch was reduced by 31% in the final year. The presence of groundcover reduced total fruit production over the whole trial by 16% and marketable fruit by 19%. In the last year of the experiment, total fruit production was reduced by 25%, and marketable fruit production by 40%. Over the whole trial, banana plants with groundcover produced 22% fewer suckers than the bare soil controls, with most of the effect occurring in the first 2 years. Soil temperatures at 20 cm under groundcover were as much as 0.7�C cooler than the controls in October-January, but similar for the rest of the year. This effect possibly contributed to decreased yields. Although the experiment was irrigated, the irrigation was possibly inadequate for the groundcover treatment, and competition for water between the Arachis and banana plants may also have been responsible for part of the yield depression. Rats fed on the buried Arachis seed each winter.

Full textAbstract:
Nitrogen (N) fertiliser is applied to perennial horticultural crops to increase yields, but subsequent N losses in subtropical plantations may be high due to intense rainfall and warmer temperatures. While legume cover crops could potentially contribute N to the tree crops and reduce fertiliser-N requirements, few studies have quantified potential fixed-N inputs from cover crops legumes in tropical or subtropical tree crop systems. To address this, we investigated growth and N fixation of summer-growing Pinto peanut (Arachis pintoi Krapov. & W. C. Greg cv. Amarillo) and winter/spring dominant white clover (Trifolium repens L. cv. Haifa) grown as a mixed species cover crop in two commercial subtropical avocado (Persea americana Mill. cv. Hass) plantations. Legume biomass was assessed prior to mowing of the inter-row (fortnightly in summer and every 6–8 weeks over winter) and N fixation was estimated using the 15N natural abundance technique. Biomass production was 7377 kg ha−1 (930 kg ha−1 for white clover and 6447 kg ha−1 for Pinto peanut) at the first site over the 14-month period from December 2014 to January 2016, and 4467 kg ha−1 (1114 kg ha−1 for white clover and 3353 kg ha−1 for Pinto peanut) at the second site over the same period. Estimation of N fixation was not possible at the first site, due to a lack of difference in isotopic discrimination between the legume shoots and the reference plant (kikuyu (Pennisetum clandestinum Chiov.)) material. While legume shoots accumulated 157 kg N ha−1 (38 kg ha−1 for white clover and 119 kg ha−1 for Pinto peanut) across the season at site 1, the % N derived from atmosphere (%Ndfa) in legumes was relatively low (50–60% in Pinto peanut during the warmer months and around 30% in autumn and early spring, and from 13 % in April to 69% in September for white clover). The low %Ndfa in the legumes may have been due to low rainfall or molybdenum (Mo) deficiency. Ultimately the legume cover crops contributed an estimated 50 kg fixed N ha−1, which could partially offset fertiliser N requirements of the tree crop. Our results demonstrate the need to quantify N fixation in legume cover crops to assess potential N benefits as opposed to relying on typical measurements of legume biomass and N accumulation.

Full textAbstract:
The management of green manure with perennial herbaceous legumes has emerged as an interesting practice for vegetable production, improving the cultivation environment and increasing crop yields. In the present study we evaluated the organic okra cultivation in soil covered with perennial herbaceous legumes. The treatments consisted of okra grown in bare soil (control) or covered with tropical kudzo (Pueraria phaseoloides), perennial soybean (Glycine wightii), calopogonium (Calopogonium muconoides), Pinto peanut (Arachis pintoi) and Stylosanthes capitata and Stylosanthes macrocephala. A randomized block design with four replications was used. The weeding of legumes was realized before the okra was sown and this allowed the addition of quantities of dry matter, highlighting the potential of tropical kudzo (3.74 t ha-1), perennial soybean (1.55 t ha-1) and peanut (1.30 t ha-1). Okra cropped in soil covered with tropical kudzo and perennial soybean had the weed lowest dry matter accumulation until 150 days after sowing the okra. At 150 days after sowing the okra, only the areas covered with peanut and calopogonium had higher volumes of water in the soil compared to the control. Throughout the harvest, the okra plants grown in soil covered with perennial soybean and tropical kudzo showed the greatest heights. The maximum okra fruit yield (16.23 t ha-1) was obtained by growing okra in soil covered with perennial soybean.

Full textAbstract:
Indirect immunofluorescence microscopy and freeze-fracture have been used to identify overlapping subdomains at the peripheral rim of the sperm-head plasma membrane (PM) and the margin of the outer acrosomal membrane (OAM) comprising the principal segment of the acrosome of the boar spermatozoon. An array of ridge-like structures (spaced 12–16 nm centre-to-centre), originally observed on the OAM by Aguas & Pinto da Silva, lies just beneath an area of the PM that is sparsely populated with large intramembranous particles compared to that of other regions of the head PM. This region has a high specificity for the lectin arachis hypogaea (peanut agglutinin). We suggest that the OAM at the rim of the sperm head may be rich in acidic phospholipids and that the close apposition of this membrane with a region of the PM relatively poor in integral membrane proteins may provide sites for initiating the acrosome reaction.

Este trabalho foi realizado com o objetivo de avaliar a massa de forragem (MF), a taxa de acúmulo diário (TAD), a oferta de forragem (OF), a taxa de lotação (TL), a porcentagem de Arachis pintoi (PAR), o ganho médio diário (GMD) e o ganho por hectare (GPV/ha) de novilhas de corte em pastejo de Coastcross-1 consorciada com Arachis pintoi. Os consórcios avaliados foram: CA0 = coastcross + Arachis pintoi sem adubação nitrogenada; CA100 = coastcross + Arachis pintoi com 100 kg de nitrogênio; CA200 = coastcross + Arachis pintoi com 200 kg de nitrogênio; e C200 = coastcross com 200 kg de nitrogênio, distribuídos em delineamento de blocos ao acaso, com duas repetições. O manejo do pasto foi o de lotação continua com carga animal variável utilizando-se novilhas mestiças com três animais-testes por consórcio. A massa de forragem nas pastagens de coastcross + Arachis pintoi adubadas com 0, 100 e 200 kg de nitrogênio e na pastagem de coastcross adubada com 200 kg de nitrogênio foi de 2.641, 2.431, 2.760 e 2.704 kg de MS/ha, respectivamente. A taxa de acúmulo diário foi semelhante (66,12 kg de MS/ha) entre as pastagens; o verão foi a estação de maior produção, seguido da primavera, do outono, que não diferiram entre si, e do inverno (108,6; 71,1; 54,2; 30,6 kg de MS/ha, respectivamente). Na associação de coastcross + Arachis pintoi sem adubação nitrogenada, foram obtidas a maior oferta de forragem e a menor taxa de lotação (4,0 UA/ha). As maiores taxas de lotação e as menores ofertas de forragem foram observadas com a adubação nitrogenada. A porcentagem de Arachis pintoi foi maior na primavera e, na associação coastcross + Arachis pintoi sem adubação, as estimativas visuais foram sempre superiores às medidas, em virtude do baixo teor de matéria seca dessa leguminosa. O ganho médio diário foi maior no cultivo em consórcio e adubação com 200 kg de nitrogênio e na pastagem de coastcross em cultivo exclusivo com 200 kg de nitrogênio em comparação àquelas de coastcross + Arachis adubada com 100 kg de nitrogênio e sem adubação (0,51; 0,51; 0,42 e 0,38 kg/dia, respectivamente). Os ganhos anuais por hectare foram superiores a 1.000 kg/ha/ano e foram maiores no verão (221,4 kg/ha).

O objetivo com este trabalho foi avaliar a composição botânica e química do pasto de Coastcross + Arachis pintoi; Coastcross + Arachis pintoi com 100kg/ha de nitrogênio (N); Coastcross + Arachis pintoi com 200 kg/ha de N; e Coastcross com 200kg/ha de N, nos períodos de inverno, primavera, verão e outono. Utilizouse delineamento experimental em blocos ao acaso com os tratamentos em esquema de parcelas subdivididas, com duas repetições (blocos). Avaliouse as percentagens de lâmina foliar verde, colmo+bainha verde, material morto e Arachis pintoi, bem como a razão folha/colmo (RF:C), além dos teores de proteína bruta, fibra em detergente neutro e digestibilidade in vitro da matéria seca. A utilização de 200kg/ha de N proporcionou a maior percentagem de lâmina foliar verde (32%) e de colmo+bainha verde (58%), porém com redução nas percentagens de material morto (10%). No outono e no verão houve maiores percentagens de lâmina foliar e redução do material morto. Na primavera houve maior percentagem da leguminosa na massa de forragem. A adubação nitrogenada exclusiva ou associada ao Arachis pintoi aumentou os teores de proteína bruta e digestibilidade in vitro da matéria seca e reduziu o teor de fibra em detergente neutro da Coastcross. A associação entre leguminosa, adubação nitrogenada e condições climáticas favoráveis, proporciona melhor composição botânica e valor nutritivo do pasto consorciado.

Arachis pintoy can be reproduced in generative but also vegetative way, for example through cuttage. Problems arising from this reproduction method is the difficulty to form roots. The success rate of this method depends significantly on the size of the formed callus. To analyze the content of nutrients contained in the cuttage stem, we have to cut off the stem. And then it’s necessary to find out additional factors that can influence the forming of the callus with a large percentage of rooting. One alternative solution is the provision of coconut water which believed to contain a variety of nutrients and growth substances. Therefore, we conducted a study to find out the interaction of these two factors on the growth of Arachis pintoy The purpose and goal of this research is to study and identify the growth Arachis pintoy which treated with coconut water its influences on the stem length. This research has been performed in Agrostology Lab of Animal Husbandrys Faculty of Sam Ratulangi University, during a period of 60 days. The research materials consists of Arachis pintoy, Coconut Water and soil. While the research method use 2 experimental factors: Factor A is the Coconut water, Factor B is the after-cuttage-stem length of Arachis pintoy, which arranged through completely randomized design (CRD). Each factor consists of 3 treatments, which repeated 3 times. These factors are as follows: A = volume of Coconut water, A1 = 100 ml of coconut water, A2 = 200 ml of coconut water, and A3 = 300 ml of coconut water. Factor B = stem length of Arachis pintoy, B1 = 10 cm, B2 = 15 cm, and B3 = 20 cm. And the variables which measured in this study were plant height, dry weight of roots and the roots volume. The results showed that administration of coconut water and the length of the cuttings as well as the interaction of two factors give significant effect (P < 0.05) to the growth of the number of leaves and root dry weight of the Arachis pintoy . Furthermore, coconut water does not give effect to the root volume and a combination of two factors do not impact on the growth of plant height. From the data analysis and discussion for all variables in this study , we can conclude that the best combination of growth in the number of leaves , dry weight of roots and root volume is the provision of 300 ml of coconut water and 10 cm stem length.

Full textAbstract:
The slope of land in oil palm plantation areas is the one of the primary causes of low soil water content due to low rates of soil infiltration. Biomulch is one of the conservation methods that can be used to cover and shield the soil from weeds, prevent soil erosion, and increase the rate of soil infiltration. Arachis pintoi is a perennial, stoloniferous legume crop that has potentials to be used as biomulch. The objective of the research was to study the role of Arachis pintoi in increasing the rate of soil infiltration on a sloping land of oil palm plantation. The research was conducted on the slope land (22.8%) of the Bukit Kemuning Farmer Group, Mersam, Batanghari, Jambi, Indonesia (01036'21", 102057'11") from September 2017 to March 2018. The environmental design used in this study was a one-factor randomized block design (RBD) with five ground cover treatments, i.e. natural vegetation, Arachis pintoi, Centrosema pubescens, Pueraria javanica and Calopogonium mucunoides. The results showed that the average growth rate of A. pintoi was 2.47 cm per week, which was lower than the growth of other treatments. The root length of A. pintoi was 50.36 cm at 20 weeks after planting. A. pintoi can be used as biomulch; sloping land planted with A. pintoi had an infiltration rate of 49.30 cm per hour at 20 week after planting, i.e. an increase of 32.47% compared to the infiltration rate with the natural vegetation.Keywords: land cover crop, Centrosema pubescens, Pueraria javanica, Calopogonium mucunoides

Full textAbstract:
Arachis pintoi is one of the many perennial peanuts grown in many tropical and subtropical countries around the world. Although Peanut mottle virus (PeMoV) was reported in Arachis glabrata from Georgia in 2007, there are no reports of PeMoV infecting A. pintoi in the United States. In June 2017, samples of A. pintoi that originated from Hardee County, FL, plants showed a variety of symptoms ranging from yellowing to dark islands, green vein banding, and mild mottling. They tested positive initially with broad-spectrum lateral flow antibody immunoassay and later were confirmed by sequencing the reverse-transcription PCR products. Detection of PeMoV in A. pintoi is significant because it is transmitted by aphids in a nonpersistent manner and is seed-borne in A. hypogea. It is not known if PeMoV is seed-borne in A. pintoi. However, A. pintoi is commonly vegetatively propagated using stolon cuttings. It is possible that PeMoV can spread to A. pintoi in Florida by all these means, making maintenance of virus-free propagation stock plants important. To our knowledge, this is the first report of PeMoV in A. pintoi the United States.

Neste Trabalho objetivou-se avaliar o efeito dos tratamentos prévios na germinação e no vigor de sementes de Arachis pintoi Krapov. & W. C. Greg.. O delineamento experimental adotado foi inteiramente casualizado, em esquema fatorial (2 lotes x 7 tratamentos), com quatro repetições. Para isto, foram utilizados dois lotes comerciais de sementes com o pericarpo (frutos) de Arachis pintoi, da cv. Amarillo, que estavam armazenados por seis e 12 meses. Por lote, foram empregados os tratamentos de remoção ou não do pericarpo, de quebra do pericarpo, de exposição dos frutos íntegros ao aquecimento a 45º C por 48 e 72 horas e à hidratação por 24 e 48 horas. Posteriormente, por tratamento, foi realizada a avaliação do grau de umidade, da germinação e do vigor (primeira contagem e emergência de plântulas). A remoção do pericarpo tornou as sementes mais vulneráveis à ação dos microrganismos. O aquecimento a 45º C por 48 e 72 horas propiciou a redução das sementes não germinadas. A hidratação por 48 horas favoreceu a germinação e o vigor das sementes de Arachis pintoi.

In two in vitro experiments with the RUSITEC-apparatus, Brachiaria dictyoneura was tested alone and with legumes at dietary proportions of 1/3, 2/3, or 3/3 of Arachis pintoi (Expt 1) and 1/3 of Arachis pintoi, Cratylia argentea, or Calliandra calothyrsus (Expt 2). In Expt 2, all diets were evaluated with and without 80 mg/g diet of Sapindus saponaria fruits. In Expt 1, the stepwise replacement of the grass by A. pintoi curvi-linearly increased rumen fluid concentrations of ammonia, volatile fatty acids, bacteria, and protozoa. Methane release rates were 1.7, 7.3, 8.8, and 9.0�mmol/day. With increasing legume proportion, more organic matter and protein were degraded, the latter being only partially recovered as ammonia. In Expt 2, 1/3 of A. pintoi basically had the same effects as in Expt 1. Cratylia argentea was less effective in modifying the fermentation pattern. In association with a higher nutrient degradation and rumen ammonia concentration, C. argentea and A. pintoi increased methane release to about 3- and 4-fold levels. Calliandra calothyrsus reduced nutrient degradation and methane release per gram of organic matter degraded. Tannins, predominant in C. calothyrsus, might have affected methanogenesis. Sapindus saponaria reduced methanogenesis by 11% on average in grass-alone and legume-supplemented diets.

Também foi determinado o balanço de nitrogênio. Os animais foram colocados em gaiolas metabólicas e receberam apenas o feno de A. pintoi mais sal mineral como componentes da dieta. O Arachis pintoi foi colhido com aproximadamente 100 dias. O fornecimento do feno foi ad libitum, sendo a quantidade calculada para permitir sobras de 20%. O experimento teve 20 dias de duração, sendo 15 dias de adaptação e cinco dias para coletas de amostras do feno, sobras, fezes e urina. Foi utilizado o óxido crômico, em duas doses diárias de 1 g cada, como indicador externo para estimar a produção fecal. Os consumos de MS e MO do A. pintoi foram 90,17 e 85,67 g/kg0,75, respectivamente. Os teores de PB, nutrientes digestíveis totais (NDT) e energia metabolizável (EM) foram, respectivamente, 14,3%, 66,4% e 2,0 Mcal/kg MS. O balanço de nitrogênio (N) foi de 12,1 g/dia e representou 40,2% de todo N consumido. As digestibilidades aparentes totais da MS, MO, PB, EE, CHO, FDN, CNF, FDA, CEL, HCEL e energia foram 64,4, 68,4, 70,0, 63,4, 68,2, 53,6, 93,3, 47,2, 62,8, 66,8 e 63,7%, respectivamente. O feno de Arachis pintoi apresentou consumo e digestibilidades dos nutrientes elevados para uma forrageira, permitindo assim fornecer nutrientes em quantidades suficientes para ganhos de peso satisfatórios, o que dá maior suporte para o uso dessa leguminosa na alimentação de ruminantes.

The research was carried out to evaluate the potential phytoextraction and phytostability of perennial peanut (Arachis pintoi) and to determine the influence of the isolated microorganisms from the root nodules of Arachis pintoi on coppercontaminated soil to improve the ability of treatment metal in soil pollution. Perennial peanuts were planted in the experimental pots which had unsterilized and sterilized soil. Different quanlities of CuSO4.5H2O were directly homogenized into sieved soil to formulate mixtures containing Cu in concentrations (mg/kg) of 200, 400 and 600. In addition, sterilized soil was contaminated by adding Cu with 400 mg/kg. The other pots had copper- contaminated sterilized soil and was added the isolated microorganisms from the root nodules of Arachis pintoi. Our results showed that the perennial peanut had high phytomass production and grew normally in the soil with 200 mg/kg of Cu. The copper accumulation was determined of 668.2, 107 and 561.2 mg/kg in the whole plant, roots and shoots, respectively in plants which were cultivated in the soil with 200 mg/kg of Cu. In the soil with 400 mg/kg and 600 mg/kg of Cu, the plants showed low biomass production and the plants had been poisonous. Both bioconcentration factors (BCF) and translocation factors (TF) were used to estimate a plant’s potential for the purpose of phytoremediation. The highest BCF and TF for Cu concentrations were 3.341 and 5.24 with 200 mg/kg of Cu, respectively. Both factors were higher than 1 therefore Archis pintoi is a potential plant for copper phytoextraction in copper contaminated sites at the concentration of 200-400 mg/kg. The isolated microrganism from the root nodules of Arachis pintoi on copper- contaminated soil was Burkholderia kururiensi PR1, which was a species of proteobacteria and stimulated plant growth. However, the result showed that Burkholderia kururiensi is unable to resistant to concentration of copper (25 mg/L). More research on the other isolated microorganisms of the root system to enhance the Cu accumulation in plants should be carried. Finally, these results showed the potential of the heavy metal phytoextraction of the perennial peanut in contaminated soil. It is easy to apply because of the low cost.

ABSTRACT The search for alternatives to increase productivity and sustainability of livestock production in the Amazon region without increasing deforestation is challenging. Mixed pastures of grasses with forage peanut (Arachis pintoi) have shown positive economic impacts. However, gaps in the knowledge of the reproductive biology of A. pintoi have limited the development of new cultivars adapted to the environmental variations in the Brazilian Amazon. Pasture consortiums of Brachiaria humidicola with forage peanuts (cv. Mandobi) resulted in a 42% increase in weight gain productivity. New cultivars better adapted to the Amazon climate should bring even greater gains. We evaluated the mating system in twenty A. pintoi accessions, and approximately 40 offspring per accession genotyped with eight microsatellites (or markers). The parameters of genetic diversity and inbreeding, the outcrossing rate and coancestry were calculated. The observed heterozygosity was significantly higher and the fixation index was significantly lower in adults compared with the offspring. The crossing rate was variable among genotypes (2 to 80%), and the mean outcrossing rate was 36%. These results indicate that pollinator presence in pastures can influence gene flow in A. pintoi more than expected. Arachis pintoi presented a mixed mating system with a predominance of selfing, and families presented inbreeding and different levels of relatedness. New strategies of genotype conservation are needed to avoid pollinator-mediated crossing between accessions.

Este trabalho foi conduzido para se determinar a composição de n-alcanos (C24 a C36) em diferentes proporções de dietas hipotéticas de Brachiaria brizantha Stapf. cv. Marandu e Arachis pintoi Koprov & Gregory. cv. Amarillo (0; 15; 30; 45; 60 e 100% de Arachis pintoi) e identificar a combinação de alcanos que permite calcular a composição botânica de dietas com o menor valor residual (real menos o estimado). As forragens foram amostradas no verão e os n-alcanos extraídos pelo método de saponificação direta, sendo identificados e quantificados por meio de análise de cromatografia gasosa. O alcano C34 foi utilizado como padrão interno. As proporções de A. pintoi nas dietas foram estimadas pela minimização do z (soma dos quadrados dos desvios) entre a proporção real dos alcanos analisados e as proporções pré-estabelecidas (tratamentos), utilizando-se a equação de Duncan et al. (1999). Observou-se que houve predomínio das cadeias carbônicas ímpares e que a concentração total de n-alcanos decresceu à medida que se aumentou a proporção de A. pintoi nos tratamentos. Estimativas acuradas da composição botânica de misturas de A. pintoi com B. brizantha foram obtidas utilizando-se os alcanos C29, C31, C33 e C35. O alcano C35 foi fundamental para a qualidade das estimativas. Os resultados indicaram o grande potencial da técnica para estudos com animais em pastejo.

Full textAbstract:
The legume Arachis pintoi has a number of characteristics which enable it to make a valuable contribution to the development of sustainable and productive pastures in the tropics. It was introduced to Costa Rica for this reason, in 1987. The objective of this study was to analyse the adoption of A. pintoi as a forage legume in Huetar Norte, a region in the north of Costa Rica. The adoption process was analysed to identify the contributory factors and to make recommendations for measures which could be taken to promote the process. To collect the data, 115 randomly selected livestock holders and an additional 34 farmers known to have planted A. pintoi were interviewed. Farmers see improved pastures to be the most important technology to enhance forage and cattle production. It was confirmed that A. pintoi is a potential improved pasture alternative. Although A. pintoi was well known., the adoption rate was low. Lack of availability of seed, technical assistance and information about the use and management of A. pintoi hinder adoption. Difficulties in establishment and maintenance were also recorded.

Full textAbstract:
Forage peanut (Arachis pintoi) is one of the forage crops best adapted to tropical agroecosystems where it is used as ground cover in urban areas and slopes, in the preservation of soils cultivated with coffee, African oil palm and citrus and as animal feed in combination with gramineous plants. A. pintoi is considered to be highly resistant to plagues and diseases; however, in recent years there has been a marked increase of plants showing symptoms typical of viral infection. In this work, Next Generation Sequencing (NGS) was used to confirm the presence of virus in symptomatic A. pintoi plants collected in urban areas in Medellín (Colombia). Transcriptome analysis revealed the presence of 3,291,089 reads related to viruses in the families Potyviridae, Luteoviridae and Alphaflexiviridae and resulted in the complete genome assembly of Peanut mottle virus (9707 nt), Turnip yellows virus (5578 nt) and two variants of a virus with phylogenetic affinity to the genus Allexivirus. These two variants lack ORF6 present in Allexivirus and probably belong to an uncharacterized genus within the family Alphaflexiviridae. The presence of at least three viruses infecting A. pintoi in Colombia highlights the importance of starting a germplasm clean-up program of the plant material used as seed in this crop.
