Soil and water loss from plots were recorded over five years (2001 to 2005) in an experiment comparing five different agricultural treatments on sloping red soil. Results showed that Bahia grass (Paspalum notatum Flugge) cover was an important factor for soil preservation, despite the presence of citrus tree planting or alley cropping in plots. The traditional rotation system (soybean [Glycine max L.]-radish [Raphanus sativus L.]) was shown to be unsuitable for soil and water conservation. However, changing crops should not be conducted during the period of high rainfall intensity. The effect of contour tillage was more significant than downslope tillage. Rainfall and rainfall erosivity did not differ significantly during the investigation period, whereas soil erosion decreased significantly over time. Planting citrus trees with Bahia grass cover generated the least runoff and sediment yield and showed a significant decreasing erosive trend with time. Thus, it proves to be an excellent choice for conserving soil and water resources on the red slopes of southeastern China.

“…Fernán-dez et al (2012) stated that the conserved treatments (seeding and mulching + seeding) did not significantly increase soil cover or affect runoff, but soil losses were low in all cases. Li et al (2011) found that the grass mulch significantly reduced sediment yield at large plot scale. Liu et al (2012) successfully reported the decreasing effect of rice straw mulch at plot scale for a period of 2 years in the Xiaofuling watershed in China.…”

“…The results (Table 2) showed that the straw mulch treatment essentially reduced soil loss and also sediment concentration (Mannering and Meyer, 1963;Adams, 1996;Adekalu et al, 2007;Groen and Woods, 2008;Smets et al, 2008;Jiang et al, 2011;Li et al, 2011;Gholami et al, 2013;Fernandez and Vega, 2014). This indicates that the flow could not get enough power to detach particles (Poesen and Lavee, 1991) with an amount of 0.5 kg m −2 because the depth of the mulch trapped detaching soil aggregates.…”

Abstract. Various organic and inorganic mulches are used for soil conservation purposes, the effectiveness of which on soil characteristics has not been comprehensively considered from different aspects. The present study surveys the efficiency of straw mulch, manure and TA-200 polyacrylamide with respective rates of 500, 300 and 50 g m −2 in changing sediment concentration and soil loss. The experiments were conducted for sandy-loam soil taken from a summer rangeland, the Alborz Mountains, northern Iran. The experiments were performed under laboratory conditions with simulated rainfall intensities of 30, 50, 70 and 90 mm h −1 and a slope of 30 %. The results showed that the straw mulch decreased soil erosion at rate of 45.60 % compared to the control plots and performed better than manure (8.98 % reduction) and PAM (4.74 % reduction). The results showed that the maximum reduction in sediment concentration and soil loss for all soil amendments occurred at the rainfall intensity of 90 mm h −1 with the rates of 58.69 and 63.24 % for straw mulch, 14.65 and 13.14 % for manure and 20.15 and 23.44 % for TA-200.

“…However, the most frequent use of this species is in the formation of lawn for protection and control of erosion in areas with exposed soils, after the end of civil construction, such as the sides of slopes, terraces of sheds, roadsides or highway medians and hydroelectric dams, besides areas with sharp declivity (Stibinger, 2011;Li et al, 2011;Coan et al, 2012;Lu, 2014).…”

A B S T R A C TThis study aimed to evaluate the effect of sequential applications of plant regulators on growth and seedhead emergence of Bahiagrass (Paspalum notatum). The study was carried out on a 15-month-old lawn, in a randomized block design, with four replicates. The treatments consisted of the following plant-growth regulators and dose: trinexapacethyl in sequential application of 113 + 113, 226 + 113, 226 + 226, 452 + 113, 452 + 226, 452 + 452 g a.i. ha -1 ; trinexapac-ethyl in single application of 678 and 904 g a.i. ha -1 ; and prohexadione-calcium in sequential application of 100 + 100 and 200 + 200 g a.i. ha -1 , besides a control, with no application. The effects of treatments were evaluated based on visual injury, plant height, height and number of flower rachises and total dry matter production of clippings. Sequential applications of prohexadione-calcium at 100 + 100 or 200 + 200 g a.i. ha -1 were efficient to reduce plant height, but did not show efficacy to reduce the number and height of seedheads or the total dry matter of clippings of Bahiagrass. However, Bahiagrass lawns can be managed by trinexapac-ethyl sequential applications of 452 + 452 g a.i. ha -1 or single application of 904 g a.i. ha -1 , with reduction in the need for mowing for a period of up to 113 days after application, without causing any deleterious effect on the visual aspect of the lawn.Redução do crescimento e do florescimento de Paspalum notatum com aplicações de trinexapac-ethyl ou prohexadione-calcium , trinexapac-ethyl em aplicação única a 678 e 904 g ia ha -1 e prohexadione-calcium em aplicações sequenciais nas doses de 100 + 100 e 200 + 200 g ia ha -1 , além de um controle sem aplicação dos produtos. O efeito dos tratamentos foi avaliado quanto à injúria visual, altura de plantas, altura e emissão de hastes florais e produção de matéria seca de aparas. As aplicações sequenciais de prohexadionecalcium, independente da dose testada, foram efetivas na redução da altura de plantas mas não apresentaram eficiência na redução do número e altura de inflorescências nem na quantidade total de matéria seca produzida pela grama-batatais; entretanto, gramados formados com a grama-batatais podem ser manejados com o trinexapac-ethyl em aplicação sequencial de 452 + 452 g ha -1 ou em aplicação única na dose de 904 g ha -1, com a redução da necessidade de cortes por um período de até 113 dias após a aplicação sem que ocorra efeito deletério no aspecto visual sobre o gramado.
