Numerosos estudios se han realizado en relación al momento de Inundación en el Centro para distintos cultivares, en los que se observaron mejores o
iguales rendimientos con el momento de inundación temprana en relación a la tardía (Lavecchia y Marchesi, 2002, 2003 y 2005; Lavecchia y Méndez, 2007 y Lavecchia, 2010).
En la zona Norte en suelos con pendientes más pronunciadas en relación a la zona Centro, se viene implementando otro tipo de sistematización que consiste en realizar múltiples taipas (taipas muy próximas entre sí) con un taipero diferente al convencional el cual permite formar taipas triangulares sin lomo ni desgote y de menor altura en relación a las taipas convencionales.
La formación de este nuevo tipo de taipas de menor altura en el sistema de múltiples taipas permitiría entre otras ventajas una inundación aún más temprana del cultivo.
Es así que en la zafra 2013 -2014 se realizó este experimento en la Unidad Experimental de Cinco Sauces, a efectos de cuantificar si los momentos de inundación temprano en distintos tipos de sistematización permitirían aumentar el rendimiento de arroz. |

Conservative biological control promotes the use of native natural enemies to limit the size and growth of pest populations. Although spiders constitute one of the most important groups of native predators in several crops, their trophic ecology remains largely unknown, especially for several generalist taxa. In laboratory, we assessed the predatory behaviour of a wandering spider (the wolf spider Lycosa thorelli (Keyserling, 1877) against several arthropods varying in size and trophic positions, all found in South American soybean and rice crops. As prey we used the bug Piezodorus guildinii (Westwood, 1837) as well as larvae and adults of the moth Spodoptera frugiperda (Smith, 1797), both being considered important pests in Uruguayan crops. We also used several non‐pest arthropods as prey, sarcophagid flies, carabid beetles and wolf spiders. All prey were attacked in more or less high, although not statistically differing, proportions. However, carabids were not consumed, and bugs were consumed in significantly lower proportions than flies. A negative correlation was found between prey size and acceptance rate. Immobilization times were longer against larvae when compared to moths and flies, while predatory sequences were longer for bugs when compared to flies, moths and spiders. In addition, we found a positive effect of prey size on predatory sequence length and complexity. Our results confirm the ability of spiders to attack and feed upon prey with different morphologies, included well‐defended arthropods, and their potential use as natural enemies of several pests in South American crops.
