Resumen
Este experimento se lo efectuó en la finca del señor Dr. José Walter Chávez Mendoza, en el sector San Andrés del cantón El Empalme. Los objetivos planteados fueron los siguientes: 1) determinar el comportamiento agronómico de las variedades de arroz: INIAP-14 e INIAP-18, cultivadas
en dos tipos de suelo, con dos láminas de agua; y, 2) cuantificar la absorción de macroelementos de los tratamientos. Los factores estudiados fueron: variedades, texturas y láminas de agua; se
utilizó un diseño de bloques al azar, se midieron variables agronómicas y químicas en tejidos. Las conclusiones que se tuvieron del presente trabajo de investigación fueron: 1) las variedades de arroz tuvieron un comportamiento agronómico prácticamente igual; 2) los tipos de suelos influyeron significativamente en las siguientes variables medidas: altura de la planta, número de macollos,
número de panículas y longitud de panículas; 3) hubo una ventaja comparativa en la mayoría de las características medidas entre los tratamientos estudiados con las diferentes láminas de agua; y, 4) las
mayores absorciones de nitrógeno por la planta se dieron en la variedad INIAP-18, en suelos francos y con láminas de agua.
This experiment was conducted on the farm of Dr. José Walter Chavez Mendoza in the San Andres in the canton the Splice. The objectives were: 1) to determine the agronomic performance of the rice varieties and INIAP INIAP-14-18, if the high sheet irrigation helps to reduce the number of tillers, 2) Determine if the number of clusters decreases with a low level of water, 3) quantify the nutrients absorbed element in the various treatments. The factors studied were varieties, textures and sheets of water, we used a randomized block design, were measured agronomic and chemical variables in tissues. The conclusions that were taken of this research were: 1) rice varieties had an almost equal agronomic performance, 2) Soil types significantly affect the following variables measured as: plant height, number of tillers, panicle numbers, panicle length, 3) There was a comparative advantage in most of the measured characteristics between the treatments with different levels of water, 4) the highest nitrogen absorption by the plant were in the range of lNlAP-18 in loam and water bodies.
