“…All these values were obtained from sugar beet sown in the spring in northern Europe. Brown et al (1987) provided values of RUE TDM between 1.6-1.9, 1.3-1.5 and 1.3-1.7 g MJ -1 when sugar beet received normal irrigation, early and late stress, respectively. López-Bellido (2003) indicated approximate values of RUE TDM of 1.7 gMJ -1 for this crop in Spain, which is a lower value than those obtained in this study (Table 5).…”

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.

“…No information on the degrees of infestation of the experimental fields was given and disease incidence recordings were not presented. Sugar beet is moderately tolerant to low soil moisture content [Van der Schans and Drenth, 1989], the severity of effects of drought depending on the growth stage at which drought is experienced [Brown et al, 1987]. Under drought stress conditions, in the absence of rhizomania, irrigation treatments increase root weight, but have little effect on sugar content [Winter, 1988;Davidoff and Hanks, 1989;Van der Schans and Drenth, 1989].…”

Abstract.A field experiment was set up in 1988 to study the development of rhizomania disease of sugar beet at different inoculum levels of beet necrotic yellow vein virus (BNYVV) in soil. Five, tenfold different, inoculum levels were created by addition of the approximate amounts of 0, 0.5, 5, 50 and 500 kg infested soil per ha (the latter corresponding to 0.01% v/v calculated to the tillage layer). A drip irrigation treatment was applied to study the influence of soil moisture on disease. Susceptible sugar beet, cv. Regina, was grown for three consecutive years.In the first year, root symptoms were not observed, but BNYVV-infected plants were detected by ELISA in low numbers at all inoculum levels at harvest. After late drilling in 1989, high numbers of infected plants, up to 90-100% in plots with the highest inoculum level, were detected already in June. Root symptoms were also observed from June onwards. In both these years disease incidence increased in time and was significantly influenced by the initial inoculum level. In the third year, the whole field was heavily diseased, and only for the non-irrigated plots incidence differed for different initial inoculum levels. The expression of symptoms by BNYVV-infected plants was influenced by initial inoculum level, thus by the amount and timing of primary infection.Root weight at harvest was not affected, but sugar content decreased with increasing inoculum level already in 1988, leading to a reduction in sugar yield of 10% at the highest inoculum level. In 1989, both root weight and sugar content decreased progressively with increasing inoculum level, resulting in sugar yield reductions of 11-66% (down to approximately 3000 kg ha -1) for low to high inoculum levels compared to the control. As the control plots became contaminated, all yields were low in 1990, still showing a decrease with increasing inoculum level in the non-irrigated plots, but an overall mean sugar yield of 3323 kg ha -1 for the irrigated ones.Sodium and c~-amino nitrogen content of the root, additional quality parameters determining extractability of sucrose, showed an increase and decrease, respectively, with increasing initial inoculum level already in the first year. The relative differences in contents compared to those from the control were largest for Na content. A significant negative correlation was found between Na (mmol kg -I root) and sugar content (% of fresh weight); linear for 1988, exponential for 1989 and 1990. In spring 1989, the infestation of individual plots was assessed using a quantitative bioassay estimating most probable numbers (MPNs) of infective units of BNYVV per 100 g 20 dry soil. The relationship between the MPNs determined and root weight, sugar content and sugar yield at harvest could be described by Gompertz curves. The increase in disease incidence with increasing MPN in 1989 was adequately fitted with a logistic equation.

“…Moreover, in the dynamic treatment, greater irrigation occurred in the early and middle periods of the growing season, as compared to the static treatment, hence, dry matter production was increased. In the static treatment, the occurrence of early drought caused the root system and canopy cover to shrink and reduced solar radiation interception and water uptake, compared to the occurrence of late drought (Brown et al, 1987). …”

In this study, a simple logistic model was developed for estimating total dry matter of sugar beet under different irrigation and nitrogen levels. The experiment was conducted using line source sprinkler irrigation in 2013 and furrow irrigation in 2014. Irrigation treatments were from 44% to 130% of full irrigation and applied nitrogen treatments ranged from 0 to 240 kg N ha -1. Results showed that the model was more accurate in predicting total dry matter at harvest date with the Normalized Root Mean Square Error (NRMSE) amounting to almost 10 percent. After total dry matter estimation, a model was needed for dry matter partitioning between different organs of sugar beet. To achieve this goal, another logistic model was developed and was compared with three revised models. Finally, white sugar content of root dry matter was estimated using a quadratic equation as a function of applied water and nitrogen. Validation results indicated that total and root dry matters, and white sugar yield were estimated fairly well. Results showed that excessive water had negative effects on total dry matter and root dry matter. Also, excessive nitrogen affected root dry matter negatively too, but even the excess had positive effects on total dry matter. In contrast to common belief, our results showed that drought stress reduced both ratios of root to leaf, and root to shoot dry matter.
