“…The coefficient of variation (CV) obtained is normally smaller than 10%, indicating low variability of these parame- . These values were higher than those found in some references (López-Bellido, 2003;Tognetti et al, 2003), and very similar to the values found by other authors, such as Lopez Urrea & Montoro (2000) and Fabeiro et al (2003).…”

“…The EWRc values for fresh root weight were similar to those obtained in other studies in the Albacete area. Fabeiro et al (2003) found EWRc values for the fresh root weight of 14.0 and 18.0 kg m -3 , when applying 896 and 690 mm of water, respectively.…”

“…In an experiment with sugar beet (Beta vulgaris L.) in semi-arid areas, Fabeiro et al (2003) show that moderate restriction of water in plant growth and root thickening followed by severe restriction in the maturation period can produce high yields (up 117.64 t ha -1 ) with relatively moderate irrigation water application (6,898 m 3 ha -1 ). In a test of deficit irrigation, where the water applied ranges from 50, 75, and 100% of the estimated evapotranspiration (ET), Tognetti et al, (2003) indicate that increasing the amount of water gives benefits in terms of sugar beet root yield and sucrose accumulation.…”

The main objective of this paper is to analyse the effects of sprinkler type and height above the ground on soil water uniformity (CUs) and sugar beet yield. Irrigation was performed with a centre pivot operating under field conditions with two types of sprinklers, one with a stationary plate (SPS) and the other with a moving plate (MPS), at two heights (1 and 2.5 m). The average coefficient of uniformity (CU) of water application of individual irrigation events with SPS ranged from 74 to 81%, compared to nearly 90% from MPS. The value of the cumulative coefficient of uniformity for the set of irrigation events (CUa) for all sprinkler-height combinations exceeded 90%, a value similar to that obtained for CU S . Results do not show a clear advantage in the final crop response by using sprinklers with MPS or SPS. However, MPS, and especially those located at 1 m in height with a spacing of 1.5 m, have higher water application uniformity, achieving higher yield and yield indexes, as well as higher water use efficiency. The final yield of sugar beet was more influenced by the amount of soil water available for the crop than the small differences in soil water uniformity obtained with the centre pivot.Additional key words: Beta vulgaris L.; fixed spray plate sprinklers; rotating spray plate sprinklers; soil water uniformity; water application uniformity. ResumenEfecto de dos tipos de aspersores y alturas en el riego de remolacha azucarera con un equipo pivot El objetivo principal de este trabajo es analizar el efecto del tipo de emisor y la altura sobre el suelo sobre la uniformidad de agua del suelo (CUs) y la producción de remolacha azucarera. El riego se realizó con un equipo pivot funcionando en condiciones de campo con dos tipos de aspersores, uno con una placa fija (SPS) y el otro con una placa giratoria (MPS), a dos alturas (1 y 2,5 m). La media del coeficiente de uniformidad de agua aplicada (CU) en los riegos individuales con SPS varió entre 74 a 81%, en comparación con casi el 90% con los MPS. El valor del coeficiente de uniformidad acumulado para el conjunto de riego (CUa) para todas las combinaciones de aspersor-altura fue superior al 90%, un valor similar al obtenido para la CUs. Los resultados no muestran una clara ventaja en la respuesta final del cultivo mediante el uso de aspersores con MPS o SPS. Sin embargo, los MPS, y especialmente los situados a 1 m de altura, colocados a un espaciamiento de 1,5 m, tienen una mayor uniformidad en la aplicación del agua, logrando un mayor rendimiento y sus correspondientes índices, así como una mayor eficiencia del uso del agua. El rendimiento final de la remolacha azucarera estuvo más influenciado por la cantidad de agua disponible del suelo para el cultivo que por las pequeñas diferencias en la uniformidad de agua del suelo obtenido con el equipo pivot.Palabras clave adicionales: aspersores con placa fija; aspersores con placa giratoria; Beta vulgaris L.; uniformidad de agua del suelo; uniformidad de aplicación del agua.

“…Analisando a equação, constata-se que o ponto de máxima EUA está associado a um volume de 937,5 m 3 ha -1 , valor inferior àquele correspondente ao tratamento 1, caracterizado pela aplicação da lâmina de irrigação no período estabelecido, somada à precipitação efetiva. FABEIRO et al (2003), trabalhando com a cultura da beterraba açucareira sem cobertura morta do solo, registraram a máxima EUA (17,05 kg m -3 ) quando aplicaram a menor lâmina de irrigação (6.898 m 3 ha -1 ). É importante ressaltar que a beterraba é uma planta C3 que apresenta adaptação ao déficit hídrico, podendo desenvolver-se em tensões de água no solo ao nível de -5,0 MPa (PIMENTEL, 1998).…”

“…Nota-se que cerca de dois terços do nitrogênio acumulado pela beterraba encontravam-se na folhagem, sinalizando a qualidade nutricional da parte aérea (ainda pouco utilizada na culinária), possivelmente correlacionada ao seu valor protéico. É também possível que o manejo orgânico com cobertura morta da leguminosa gliricídia tenha contribuído para o percentual relativamente alto do N-total na folhagem (acima de 65%) da beterraba, superando o valor divulgado por GRANGEIRO et al (2007), de 52,7% em cultivo convencional.…”

RESUMO:Práticas agrícolas orgânicas, como a cobertura do solo com palha, foram testadas em área irrigada por gotejamento na Baixada Fluminense, no Estado do Rio de Janeiro. O cultivo de inverno da beterraba nesta região é favorecido por temperaturas mais amenas, coincidindo com a época de maior disponibilidade do produto no Estado. No cultivo da beterraba, foram adotados três tipos de cobertura do solo e seis lâminas de irrigação (0; 29; 48; 78; 100 e 148% da ETc) determinadas com base no balanço de água no solo utilizando a técnica da TDR. O delineamento estatístico adotado foi blocos casualizados, com seis tratamentos e quatro repetições. Sob cobertura morta de Pennisetum purpureum, de Gliricidia sepium e na ausência de cobertura morta, os valores máximos relativos de EUA, no cultivo de beterraba, foram de 21,00; 32,90 e 17,90 kg m -3 , respectivamente. A maior e a menor lâmina de irrigação acumulada para cada tipo de manejo foram de 2.746 e 951 m 3 ha -1 nas parcelas sem cobertura morta. Em comparação, as parcelas com cobertura do solo reduziram em 34,5 e 10,5% as lâminas acumuladas, respectivamente. Os valores acumulados de nitrogênio nas partes das plantas foram maiores no cultivo sob cobertura morta de G. sepium, indicando vantagens desta prática cultural associada à irrigação por gotejamento. PALAVRAS-CHAVE:Beta vulgaris, Gliricidia sepium, Pennisetum purpureum, olericultura orgânica, gotejamento, TDR. IRRIGATION MANAGEMENT AND MULCHING IN ORGANIC BEET PLANTINGABSTRACT: Organic farming practices, like mulching, were tested in drip irrigated area in Baixada Fluminense, state of Rio de Janeiro, Brazil. In this region, the winter crop of sugar beet is favored by mild temperatures, coinciding with the period of higher product availability in the State. For the beet planting were used three soil management practices (different conditions of coverage). In each one, six irrigation depth (0, 29, 48, 78, 100 and 148% of ETc), estimated based on soil water balance using TDR technique were applied through drip of different flow rates. Moreover, it was also included a plot without irrigation. The statistical design used was randomized blocks with six treatments. Under mulch of Pennisetum purpureum, Gliricidia sepium and without mulching, the maximum values of WUE in beet planting, were 40.25, 25.63, 26.08 kg m -3 , respectively. The higher depth accumulated in the treatment relative to 29% of ETc (951 m 3 ha -1 ) was obtained in plots without mulch. The nitrogen accumulated in the plant was higher in the experiment with Gliricidia mulching, indicating advantages of this cultural practice associated with drip irrigation.
