Foliar Spray Inoculation with Plant Growth Promoting Bacteria Associated with Nitrogen Doses in Megathyrsus maximus cv. BRS Zuri

This study evaluated the combined effect of foliar spray inoculation with plant growth-promoting bacteria (PGPB) and nitrogen doses on the yield, development, and nutritive value of Megathyrsus maximus cv. BRS Zuri. The experimental design was randomized blocks with four replications, with repeated measures in time. Foliar inoculation of two bacteria (Azospirillum brasilense Ab-V5 (CNPSo 2083) and Ab-V6 (CNPSo 2084) and Pseudomonas fluorescens (CNPSo 2799)) and 40 and 80 kg ha−1 N (urea) rates, in addition to the control (without inoculation and N fertilization), were applied. In the rainy season, at the level of 40 kg ha−1 of N, inoculation of both A. brasilense and P. fluorescens increased, respectively, the tiller number by 33% and 25% (22 February), and the N accumulated in tissues by 42% and 25% (22 January), while in the previous year (21 February) the beneficial effects of both bacteria were observed in the percentage of leaf blade and in the true digestibility in vitro. When the foliar spray was inoculated with A. brasilense Ab-V5 and Ab-V6 and P. fluorescens CNPSo 2799, with 80 kg N ha−1, the root system of Zuri grass increased by 61% and 30%, respectively.

Characterization and Relationship Analysis of Various Genotypes of Collection Jatropha curcas L. Results of Crosses Based on Leaf Morphology

Jatropha (Jatropha curcas L.) is a shrub that is easy to grow. This plant has many benefits including as a raw material for biodiesel and has the potential to be developed into a future energy source. This study aims to determine the kinship hybrid numbers based on morphology. The experiment was conducted in Krajan hamlet, Kedung Pengaron village, Kejayen sub-district, Pasuruan district, East Java province. The material genetic used in this study is hybrid number 5 (SP-8 × SP-16), 6 (SP-8 × SP-38), 7 (SP-33 × HS-49), and 18 (SM-35 × SP-38). Observations were made on leaf morphology with scoring, percentage and Munsel Color Chart based on reference Sunil et al. The results showed that there was no difference between the four genotypes of the crosses tested on all leave morphology character except leaf angles on the main branch, percentage of leaf blade, leaf color, color of upper surface leaf bone, leaf green intensity, intensity of anthocyanin staining, corners of leaves, leaf scatter color, and young leaf color. Cluster analysis based on leaves morphological character showed that the J. curcas genotypes could be grouped into four clusters at cophenhetic distance of 0.6.

Management of dual-purpose wheat genotypes by rotatinuous stocking

The objective was to evaluate whether rotatinuous stocking management in dual-purpose wheat genotypes provides greater forage performance compared to the traditional rotational grazing management, which could become an alternative to ryegrass, once this new management strategy has been validated. Three dual-purpose wheat cultivars (BRS Pastoreio, BRS Tarumã and BRS Tarumaxi) and a black oat cultivar (Embrapa 139 Neblina) were used in the experiment, in traditional rotational and rotatinuous stocking. The experiment was carried out in a randomized complete blocks design, with treatments arranged in a 4 x 2 factorial scheme (cultivars x management strategies), with pre and post-harvest heights in traditional rotational management (RT) of 25 and 5 cm, and 25 and 15 in the rotatinuous stocking management (RN). The experiment was carried out at Embrapa Trigo, in Passo Fundo, Rio Grande do Sul state, southern Brazil. Nitrogen was applied after sowing and after cuts, according to the management strategies. Dry matter yield, percentage of leaf blades and forage accumulation per cut and total were evaluated. Wheat cultivars in rotatinuous stocking management showed higher numbers of cuts, greater cycle, percentage of leaves and average rate of forage accumulation, with smaller intervals between cycles. The total forage production showed no difference between the cultivars, however, BRS Tarumaxi was higher in the rotatinuous stocking management. Thus, responses between the genotypes in relation to the management strategies adopted are different.

Mixtures of rye cultivars to improve forage yield, distribution and nutritive value

The search for forage cultivars that provide higher yields with quality in periods of forage shortage, whether in isolated or mixed management, is essential for livestock stability. Thus, the objective was to evaluate the forage performance and nutritive value of rye cultivars mixtures (BRS Progresso, BRS Serrano and Temprano) from different production cycles compared to the isolated management of rye, dual-purpose wheat cvs. (BRS Tarumã and BRS Pastoreio) and black oat cv. Embrapa 139 Neblina as controls. The experiment was conducted at a randomized complete block design, with four rye associations and the isolated cultivation of wheat, oat, and rye. Dry matter (DM) yield and nutritive value, such as content of neutral detergent fiber (NDF), acid detergent fiber (ADF), and crude protein (CP) content were evaluated for each cut and total values. There was difference (P<0.001) in total DM, the highest yield was in single cultivation as well as mixtures with Temprano. BRS Serrano and BRS Progresso and their mixture had lower leaf blade percentage in the total DM. There were differences (P<0.05) in NDF concentration (55.1 to 70.60%), ADF (15.2 to 34.7%), and CP (27.4 to 36.8%) levels along harvests. Among cultivars, Temprano showed the highest proportion of leaf blades and total DM yield.

Does amount of cut vegetal residue on the canopy influence growth and the structural characteristics of marandu palisadegrass?

The pasture mowing in late winter removes the old forage, improving the pasture structure in spring and summer. However, the residue after mowing can affect tillering, thus limiting forage production and the structural characteristics of pasture. We hypothesized that the high amount of cut vegetal residues on the plants in late winter causes a decrease in forage production and modifies the structural characteristics of the forage canopy during the spring and summer. The treatments were four cut vegetal residues (0; 2,000; 4,000 and 8,000 t ha-1 of natural material) deposited on Urochloa brizantha cv. Marandu canopy in late winter. After that, the forage production and structure characteristics were evaluated during the spring and summer for two years. The complete randomized block design, with four replications, was used. The defoliation management was characterized by the adoption of pre- and post-cut heights of 25 and 15 cm, respectively. For both years, there was no effect of cut vegetal residue on all the characteristics evaluated. No variable was affected by the interaction cut vegetal residue amount × year of evaluation. The dead leaf blade percentage was greater in year 2 (6.9%) than in year 1 (3.5%). The average values of variables were live leaf blade percentage = 84.2%; live stem percentage = 8.7%; dead stem percentage = 1.9%; number of vegetative tiller = 653 tiller/m2; number of reproductive tiller = 5 tiller m-2. The forage production rate presented an average value of 46 kg/ha/day of dry matter. The cut vegetal residue amount of up to 8,000 t/ha of natural material on the plants in late winter does not affect the forage production or modifies the structural characteristics of marandu palisadegrass during the subsequent spring and summer.

How does the condition of the pasture in late winter influence the plant and animal responses in the subsequent seasons?

This study aimed to test the hypotheses: (i) the deferred pasture with lower height in late winter has greater herbage accumulation rate (HAR) and better structure, which facilitates the animal selective grazing during the subsequent spring and summer; (ii) the mowed of high pasture in late winter improves the sward structure but decreases its HAR from the spring. Four pasture condition in late winter of Urochloa brizantha cv. Marandu were evaluated: low (24.1 cm and 2,420 kg.ha-1 of DM); low/mowed (25.2 cm and 2,198 kg.ha-1 of DM, mowed at 8.0 cm); high (49.0 cm and 3,837 kg.ha-1 of DM); and high/mowed (50.0 cm and 4,211 kg.ha-1 DM, mowed at 8.0 cm). The highest live leaf blade percentage (LLBP) and the lowest dead stem percentage (DSP) occurred in the mowed pastures. The live stem (LSP) and dead leaf blade percentages of the grazing simulation sample were higher in the high pasture. This same pattern of response occurred for apparent selectivity indices (ASI) of the live leaf blade and live stem. The ASI of the dead leaf blade was greater in the high pasture, intermediate in the mowed pastures, and lower in the low pasture. The ASI of the dead stem was lower in the low pasture. The HAR was higher in low pasture. Our results support the first hypothesis. The mowing of high pasture in late winter improves the sward structure and the animal selective grazing but does not decrease the HAR during spring and summer.

Nitrogen fertilisation as a strategy for intensifying production and improving the quality of Massai grass grown in a humid tropical climate

The use of nitrogen fertilizers intensifies forage production, especially in tropical climates. This study aimed to evaluate the effects of nitrogen fertilization on the quantitative and qualitative characteristics of Massai grass grown in a humid tropical climate, specifically Am-type. A completely randomized design was used with six treatments and five replicates. The treatments used were a control treatment (without nitrogen application) and five doses of nitrogen fertilization (100, 200, 300, 400, and 500 kg N ha−1 year−1). Urea was used as the nitrogen fertilizer for six applications, with an interval of 30 days. The leaf elongation rate increased by 69.1% at a dose of 500 kg N ha−1 compared to that of the control. The leaf appearance rate and green leaves per tiller increased with nitrogen fertilization. Nitrogen fertilization did not affect the percentage of leaf blades and dead tissue. The average height of the canopies was 44.0 cm, regardless of fertilization. There was a quadratic response in total forage accumulation (TFA), with a maximum of 19,136 kg dry matter at a dose of 391 kg N ha−1year−1. Nitrogen utilization efficiency was the same as that of TFA. There was a reduction in the recovery of applied nitrogen and the agronomic efficiency of applied nitrogen with nitrogen fertilization. The number of cuts increased linearly with nitrogen fertilization, from 3.2 to 7.5 cuts. Crude protein content increased with nitrogen fertilization. Therefore, nitrogen fertilization favored the productivity and quality of Massai grass grown in a humid tropical climate.

Establishment of paiaguas palisadegrass in monoculture or in an integration system with other crops

Abstract The objective of this study was to evaluate the productive and structural characteristics of Paiaguas palisadegrass established in monoculture and intercropped with agricultural crops in 2018 and 2019. The evaluated treatments were: Paiaguas palisadegrass (PP) in monoculture, PP intercropped with maize, PP intercropped with sorghum, and PP intercropped with soybean. The experimental design used was a randomized block, with 4 replications (plots of 160 m²). Sward height, tiller density, dry mass production, and bulk density of total dry matter, of leaves, of stems, and of dead material were evaluated. The data were analyzed using the Tukey test at 5% probability. The total dry mass was higher in intercropping than in monoculture. Paiaguas palisadegrass intercropped with maize showed lower productions of total dry mass, leaf blade, and stems. The percentage of leaf blades was higher in Paiaguas palisadegrass intercropped in 2018 and in monoculture and intercropped with maize and soybean in 2019. Higher percentages of stems were registered in Paiaguas palisadegrass in monoculture in 2018 and in intercropping with sorghum in 2018 and 2019. In general, higher heights were found in Paiaguas palisadegrass in monoculture and smaller when intercropped with maize. The highest tiller densities were observed in Paiaguas palisadegrass in monoculture and the lowest in Paiaguas palisadegrass intercropped with maize and sorghum. Intercropping with agricultural crops reduces the production of Paiaguas palisadegrass. The accompanying agricultural crops alter the composition of the forage produced by the Paiaguas palisadegrass.

This research was aimed to determine the effect of beef fertilizer on growth and biomass production in some corn hybrid varieties (Zea mays). This research used completely randomized design factorial 6 x 4 with four replications. The first factor is the corn hybrid varieties were V1 (Bisi-2), V2 (Bisi-16), V3 (Bisi-222), V4 (Nk-212), V5 (Pertiwi-2), V6 (Pacific-224), and the second factor was the level of beef fertilizer were P0 (0 ton/ha), P1 (20 ton/ha), P2 (30 tons/ha), P3 (40 tons/ha). The parameters measured were growth of plant height, the fresh water production and leaf blade percentage of corn hybrid varieties. The results showed that the variety and level of treatment of fertilizer was highly significant effected (P0,01) to the plant high, the fresh water production and leaf blade percentage corn hybrid varieties. Interaction factor were significant effected (P0.05) to the fresh water production, whereas in the growth of plant high and leaf blade percentage did not effected (P0.05). Each treatment was getting the best results in plant height at V2P3 (224 cm), fresh water production at V4P3 (5234 g/plot) and leaf blade percentage at V4P2 (35.35%).

Effect of Repeated Application of Manure on Herbage Yield, Quality and Wintering Ability during Cropping of Dwarf Napiergrass with Italian Ryegrass in Hilly Southern Kyushu, Japan

The effects of two levels of manure application (184 and 275 kg N ha−1 year−1) on herbage yield, quality, and wintering ability during the cropping of a dwarf genotype of late-heading (DL) Napiergrass (Pennisetum purpureum Schumach) oversown with Italian ryegrass (IR; Lolium multiflorum Lam.) were examined and compared with chemical fertilizer application (234 kg N ha−1 year−1) for 4 years to determine a sustainable and environmentally harmonized herbage production in a hilly area (340 m above sea level). No significant (p > 0.05) differences in growth attributes of plant height, tiller density, percentage of leaf blade, or dry matter yield appeared in either DL Napiergrass or IR among moderate levels (184–275 kg N ha−1 year−1) of manure and chemical fertilizer treatments. IR exhibited no significant detrimental effect on spring regrowth of DL Napiergrass, which showed a high wintering ability in all treatments. In vitro dry matter digestibility of DL Napiergrass tended to increase with increasing manure application, especially at the first defoliation in the first three years. Manure application improved soil chemical properties and total nitrogen and carbon content. The results suggested that the lower rate of manure application of 184 kg nitrogen ha−1 year−1 would be suitable, which would be a good substitute for chemical fertilizer application with an equilibrium nitrogen budget for sustainable DL Napiergrass and IR cropping in the hilly region of southern Kyushu.

Marandu palisade grass intercropped with densely spaced teak in silvopastoral system

This study was conducted to evaluate two systems of production: integration between teak and forage (silvopastoral system) and forage only (monoculture). The forage species used was Marandu palisade grass (Urochloa brizantha cv. Marandu). In January 2009, part of the pasture was desiccated and the teak (Tectona grandis) was implemented in a 3 × 4 m spacing arrangement, and at every five rows, a space between rows of 6 m was established, providing a population of 750 trees per hectare. Alongside the development of the trees, the Marandu palisade grass pasture was reestablished. In February 2015, the animals were removed from the experimental area and, in March, the pasture degradation, the density and the mass of tillers was assessed. The following variables were evaluated: sward height; forage mass, percentage of leaf blade, stem+sheath and senescent material; leaf blade:stem+sheath ratio; and live:dead material ratio. The experimental design was completely randomized, with 12 replicates. Treatments consisted of two systems (silvopastoral and monoculture). The total forage accumulation was higher in the monoculture system. The sward height and the percentage of stem+sheath were higher in the integrated system, while the percentage of leaf blade and the leaf blade:stem+sheath ratio were higher in the system exclusively with forage. In conclusion, Marandu palisade grass tolerates shading in a high density spacing silvopastoral system, but the degradation process is more intense compared to grass in monoculture, and the use of Marandu palisade grass in silvopastoral systems changes the forage mass and the structure of the produced forage.

Productive characteristics of the grass Digitaria umfolozi subjected to defoliation frequencies

An experiment was carried out to evaluate the dry matter production, total dry matter availability, daily dry matter accumulation rate, light interception, leaf area index, daily accumulation rate, dry matter availability of the morphological components (leaf blades, stems + sheaths and dead material), leaf/stem ratio, crude protein, neutral detergent fibre and acid detergent fibre of Faixa-Brancagrass under seven defoliation frequencies (14, 21, 28, 35, 42, 49, and 56 days). Longer defoliation frequencies reduced the percentage of leaf blades and increased the percentage of stems + sheaths. The defoliation frequency positively influenced the availability of leaf blades, stems + sheaths, dead material and total dry matter. In the range of 42 days of defoliation, light interception reached 95%. At frequencies of 14 and 21 days of defoliation, the crude protein content of the leaves was above 20%. The highest utilization efficiency of D. umfolozi grass is achieved when the forage is managed with cutting intervals of 40 to 46 days. Higher defoliation frequencies positively contribute to the increase in the number of total white band grass leaves and higher crude protein content of the leaf blades and stems + sheaths.

Tillering dynamic and structural characteristics of tropical grasses under cutting management

This paper aimed to evaluate the dynamics of tillering, tiller density and structural characteristics of Brachiaria brizantha , Panicum maximum and Cenchrus ciliaris under a cutting regime. The utilized design was randomized blocks with six treatments (cultivars) and three replications. The evaluations were conducted from May to September 2011, with the data grouped into two periods, rainy season and beginning of the dry season. The greatest tiller population density was observed in the Massai cultivar, averaging 1,019 tillers.m -2 . The tiller mortality rate was higher for Mombaca and less for Piata cultivars. The highest values for forage mass, percentage of leaf blades and relations between green mass:dead mass were observed in Brachiaria brizantha and Panicum maximum cultivars. Panicum and Brachiaria cultivars have shown to be promising for cultivation in the transition areas between the Atlantic Forest and Caatinga biomes in Northeastern Brazil. Cenchrus cultivars are less productive in environments without restriction of abiotic factors.

<b>Morphogenesis in pastures with Tanzania grass fertilized with nitrogen doses under a grazing system

The morphogenetic and structural characteristics, coupled to forage production of Tanzania grass with nitrogen (N) doses during the seasons of the year, at intermittent grazing, were analyzed. The experimental design consisted of a totally randomized block with split plots and four replications. The plots comprised 0, 150, 300 and 450 kg ha-1 N levels, whereas the sub-plots were the seasons. Urea was applied three times on the pasture and had a positive effect on the rates of leaf elongation and emergence and on the number of live leaves of Tanzania grass in the spring and summer. High nitrogen fertilization associated with shorter grazing intervals triggered a higher percentage of leaf blades in the management of Tanzania grass under rotational stocking at a height of 70 cm on the admittance of animals for grazing and their exit at 30 cm stubble height.

Accumulation of dry matter and morphological composition of irrigated Mombaça grass with and without nitrogen fertilizer under grazing

Brazil has the largest commercial cattle herd in the world and is the world's leading exporter of fresh and processed meat. Beef production is based on pastures and the production system is influenced by the absence of fertilization and the seasonality of forage production during the year, caused mainly by variation in temperature, rainfall and sunlight hours. Nitrogen (N) is the most important element for the development and growth of grasses, since it accelerates the formation and growth of new leaves, and improves regrowth vigor, resulting in greater production and carrying capacity of pastures (Cecato et al. 2011). The present study aimed to quantify the accumulation of dry matter and percentage of leaf blade of irrigated Mombaca grass (Panicum maximum cv. Mombaca) at 4 N fertilizer levels, under intermittent grazing.

Características agronômicas e eficiência do uso da chuva em cultivares de sorgo no semiárido

Objetivou-se quantificar o rendimento forrageiro, o percentual de componentes da planta, as características morfométricas e a eficiência do uso da chuva de cinco genótipos de sorgo para silagem no semiárido paraibano.

O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, sendo os tratamentos experimentais representados por cinco genótipos de sorgo: Ponta Negra, SF 15 IPA 1011, IPA 2502 e IPA 46742. Não foram observadas diferenças entre os genótipos para a produção de matéria natural e produção de matéria seca e para o percentual de lâmina foliar. Entretanto, para o percentual de colmo foram observados maiores valores (P<0,05) para os genótipos Ponta Negra e IPA 46742. O percentual de panícula foi superior (P<0,05) para as cultivares 'IPA 1011' e 'IPA 2502'. As cultivares 'IPA 1011' e 'IPA 2502' apresentaram percentual de panícula acima de 38% da MS. Não houve diferença (P<0,05) para eficiência no uso da água de chuva entre os genótipos estudados, com valores variando de 94,37 a 126,25kg de MS ha-1 mm-1. Os genótipos avaliados apresentam elevada eficiência no uso da chuva e produtividade. Recomenda-se o IPA 1011 pela maior participação de panícula.

<b>Defoliation patterns in signal grass tillers with varying heights in the same pasture</b> - doi: 10.4025/actascianimsci.v35i3.14376

The experiment was carried out to evaluate the patterns of defoliation in plants of various heights in the same pasture of Brachiaria decumbens cv. Basilisk under continuous stocking with cattle. Four plant heights were evaluated (10, 20, 30 and 40 cm) in the same managed sward, with mean height equal to 25 cm. A randomized blocks design was used, with two replications. Defoliation frequency increased linearly along with plant height in the same pasture. Defoliation intensity, number of defoliations in leaf blade and percentage of leaf blade grazed per tiller also increased linearly along with plant height. The defoliation interval decreased linearly according to plant height. The quadratic model was adequately fitted into grazing efficiency data, reaching the highest value (98%) at the sward site with 35 cm plants. The percentage variation in signal grass height showed a negative linear response with initial plant height. The structure of the pasture, characterized by the diversity in plant heights, is simultaneously the cause and consequence of the variability in defoliation patterns in individual tillers, which occur on the horizontal plane of the pasture.

Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure

The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels. Two levels of nitrogen (75 and 150 kg/ha) and one control without fertilization associated to three initial deferring heights (20, 30, and 40 cm) were evaluated. The design was of completely randomized blocks with three replications in a subdivided plot scheme. A raise in the initial deferment height and in the fertilization elevated the sward and extended tiller heights, the leaf area index, and the light interception by the sward. The piata palisadegrass deferred with an initial height of 40 cm presented a higher forage mass with lower percentage of leaf blades, and higher stem and dead tissue quantity. Additionally, this management strategy resulted in lower bulk density of leaf blade and in higher bulk densities of stems and dead tissue. The utilization of 150 kg/ha of nitrogen raised the production and the bulk density of deferred piata palisadegrass forage and increased production and bulk density of leaves and stems. In the region of Viçosa, Minas Gerais, the piata palisadegrass deferred with an initial height of 30 cm and fertilized with 75 kg/ha of nitrogen in the beginning of the fall presents adequate mass and structure to animal production in the winter.

PRODUÇÃO E CARACTERÍSTICAS ESTRUTURAIS DE CINCO FORRAGEIRAS DO GÊNERO Brachiaria SOB INTENSIDADES DE CORTES INTERMITENTES

This experiment happened from July 2004 to September 2005 in the Depressao Cuiabana region-MT. The objective of this study was to verify the yield and sward structure of five Brachiaria genus forages submitted to 10 and 20 cm cutting intensities. The forages were irrigated and fertilized. The cutting happened with the frequency of 30 days. The variables analyzed were forage yield, plant height, forage bulk density, leaf blade percentage, stem percentage, leaf blade/stem relation and senescence percentage. A complete randomized block design was used with treatments in a split-plot arrangement and three replications. The Mulato grass showed highest green dry matter yield (4,2 t DM/ha) followed by Xaraes palisadegrass, Signalgrass and Ruzi grass, with averages greater than 3,5 t DM/ha, while the smallest forage yield was the Marandu palisadegrass (2,9 t DM/ha). The defoliation intensity interfered in the forage structures characteristics, but cutting intensity at 20 cm favored the highest leaf blade percentage for Xaraes palisadegrass. The smallest defoliation intensity propitiated greater forage yield with higher leaf blade percentage and smaller senescence losses during the experimental period. The evaluated forages presented a potential to be used on livestock pasture-based system in the Depressao Cuiabana region, specially Mulato grass and Xaraes palisadegrass.
