“…silage was intercropped with guinea grass (Panicum maximum cv. Aruãna) in the summer/autumn, and the pasture was cut in the winter/spring (PARIZ et al, 2016(PARIZ et al, , 2017b. In the crop years of 2013/2014, 2014/2015 and 2015/2016, maize silage was intercropped with palisade grass and pigeon pea (Cajanus cajan) in the summer/autumn, and black oat (Avena strigose ) was overseeded in rows (with a seeder-fertilizer) or by broadcast seeding (manually), with grazing by lambs in the winter/spring (ALMEIDA et al, 2018).…”

The economic losses caused by gastrointestinal nematodes are one of the biggest obstacles in the small ruminants production. Understanding the population dynamics of the infective larvae (L3) in the pasture is the key point to develop control programs, and reliable results depend on the used methodology to quantify L3 numbers. The use of the sampling directly from the pasture appears as a viable option, since it is not required the use of animals with an esophageal fistula or tracer animals, decreasing the costs involved in the study. Therefore, the present project, which had as objective evaluate the efficiency of two collection methods for quantification of L3 in the pasture, utilized 64 lambs (n = 16) allocated to four integrated crop-livestock systems (treatments) with 12 paddocks each. Pasture samples were collected every nine days. The W method consists in traversing the area in the form of a W and again an inverted W, forage samples being collected every 10 steps, and the Square method, in tossing a 0.16 m 2 square to four random points within the area, the forage within the square being collected after each toss. After the forage samples had been processed, the L3 were recovered and identified. Cohen's Kappa coefficient (k) was determined. The W-transect and Random-plot methods did not differ (p ≥ 0.05) with respect to the number of L3 recovered from the pasture, and a positive correlation was found between them, suggesting agreement with one another, being that when the number of L3 recovered by the W-transect method increases, the same occurs in the Random-plot technique. The Random-plot method, which is already used to collect samples of forage for chemical analyses, can also be employed to estimate the pasture contamination by L3. The W-transect and Random-plot methods showed to be important in the epidemiological study of gastrointestinal nematodes in sheep. Therefore, the use of both on the same occasions and with different purposes, with one complementing the information that is not provided by the other, may be more effective in the investigation of environmental contamination by L3 of gastrointestinal nematodes. ResumoAs perdas econômicas causadas por nematódeos gastrintestinais são um dos maiores entraves na produção de pequenos ruminantes. Entender a dinâmica populacional das larvas infectantes (L3) no capim é o ponto chave para que se desenvolva programas de controle, e resultados confiáveis dependem das metodologias utilizadas para quantificar o número dessas L3. O uso da amostragem diretamente da pastagem aparece como uma opção viável, já que não requer o uso de animais fistulados ou traçadores, reduzindo os custos envolvidos no estudo. Assim, no presente estudo, que teve como objetivo avaliar a eficácia de dois métodos de coleta para quantificação de L3 na pastagem, foram utilizados 64 cordeiros (n = 16) alocados em quatro sistemas integrados de produção agropecuária (tratamentos) com 12 piquetes cada. As amostras de pasto foram coletadas a cada nove dias. O método W consiste em percorrer a...

“…Among the various forage grasses species grown in Brazil, Urochloa brizantha is the most widely used, mainly in the North and Center-West regions of the country. Its success is due to productivity, weather tolerance, and good adaptation to different soil types in Brazil (Meirelles et al 2011;Pariz et al 2017). These factors contributed to several Urochloa brizantha cultivars being launched on the market, of which Piatã and Paiagu as are the most recent.…”

The use of organic compost in pasture fertilization is a form of recycling nutrients contained in waste and reducing chemical fertilizer use. To perform pasture fertilization, however, grass responses to doses of organic composts must be known. Thus, the objective of this study was to find the best dose of laying hen organic compost to maximize the productive, morphogenetic, structural, and nutritional responses of Paiagu as and Piatã grasses. A completely randomized factorial (4 £ 2) design was used, composed of organic compost doses (0, 400, 800, and 1,200 kg equivalent N.ha ¡1) and two cultivars (Piatã and Paiagu as) of Urochloa brizantha grass with three replicates per treatment, assessed during four successive cuts. The parameters evaluated were dry matter yield (DM) of shoots and roots, leaf appearance rate (LAR), leaf elongation rate (LER), phyllochron, pseudoculm elongation rate (PER), final leaf length (FLL), number of green leaves (NGL), and senescence rate (SR). The nutritional value of the grasses was also assessed through contents of dry matter, organic matter, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber, cellulose, hemicellulose, lignin, and in vitro organic matter digestibility (IVOMD). DM yields of both shoot and root increased due to nitrogen increase and Paiagu as grass had the highest yields (P < 0.01). The best organic compost doses ranged from 640 to 950 kg of equivalent N.ha ¡1 for most morphogenic and structural grass characteristics. The chemical composition of grasses was not influenced (P > 0.05) by doses of organic compost. Levels of 8.05% CP, 67.10% NDF, and 65.14% IVOMD were observed for cultivar Paiagu as, while for cultivar Piatã these values were 7.58% CP, 70.32% NDF, and 63.38% IVOMD. It is concluded that high doses of an organic compost are required (in equivalent N) for cultivars to reach the highest growth rates and that Paiagu as grass has higher dry matter yield, higher growth rates, and better chemical composition when compared to Piatã grass in similar organic fertilization conditions.

“…Several studies have been conducted to improve the efficiency of this system, showing the benefits of using perennial grass species intercropped with grain crops (Borghi et al, 2013;Crusciol et al, 2015). Intercrops present positive results that improve the soil physical and biological qualities (Calonego et al, 2017;Pariz et al, 2017). They provide higher availability of nutrients in the soil, resulting in improvements in fertility and higher yields for succeeding crops (Borghi et al, 2013;Crusciol et al, 2015;Balbinot et al, 2017;Pariz et al, 2017).…”

The Brazilian Cerrado stands out in relation to grain production, however, in this region the occurrence of summer and irregular rainfall, drastically harm the non-irrigated production. Conservationist managements favor the soil physical quality and, consequently, the efficiency of soil water consumption. The objective of this study was to evaluate the soil physical quality, as a function of the conservation managements adopted, by using physical soil quality indicators, and to verify its relation with the soil organic carbon stocks and the grain yield in the Cerrado of Minas Gerais state, Brazil. For that, six treatments were evaluated: soybean (1) and maize (2) monocultures crop systems at medium level of investment in soil fertilization, soybean-maize crop succession at medium (3) and high (6) level of investment in soil fertilization, and crop succession of soybean-maize and intercropped with Urochloa ruziziensis at medium (4) and high (5) level of investment in soil fertilization, during the initial stage of no-tillage system. The treatments 3, 4, 5 and 6 showed improvement in the soil physical quality in relation to the monoculture. Pore distribution and soil organic carbon content were the main responsible for discriminating the intensified crop systems. Attributes related to water availability were important for plant growth in the 0-0.05 m layer, while for the 0.15-0.20 m layer, the highest soil aeration stood out. Productivity did not correlate with the evaluated attributes.
