Resumen
El siguiente trabajo de investigación “EVALUACIÓN AGRONÓMICA
DE TRES VARIEDADES DE Oryza sativa L. EN EL SISTEMA
INTENSIVO DE CULTIVO DE ARROZ CON DISTINTAS
CANTIDADES DE SEMILLAS POR SITIO” se realizó en los predios de
la Ciudadela Universitaria “Dr. Salvador Allende” de la Universidad de
Guayaquil. Los objetivos planteados fueron los siguientes: 1) Evaluar el
comportamiento agronómico de tres variedades de arroz cultivados con tres
cantidades de semillas por sitio de siembra. 2) Determinar los mejores
componentes agronómicos que influyen en el rendimiento del grano.
Los factores a estudiar fueron las tres variedades de arroz INIAP 14,
INIAP 18 y SFL-11 y tres cantidades de semillas, cuyos resultados de las
variables agronómicas fueron analizadas bajo el diseño experimental
Completamente al Azar, con arreglo factorial A x B con tres repeticiones y
nueve tratamientos.
Las conclusiones que se tuvieron del presente trabajo de investigación
fueron: 1) La variedad INIAP-14 e INIAP-18 presentaron el mayor
promedio de peso de 1000 semillas. 2) La variedad INIAP-14 fue superior
en promedio de altura de planta, longitud de panícula y granos panícula
planta
-1
las variedades INIAP-18 y SFL-11. 3) Con la cantidad de una
semilla sitio
-1 se obtuvo una mayor altura de planta, longitud de panícula y
granos panicula
-1
. 4) El número de macollos planta
-1, panícula por planta y peso de 1000 semillas tuvieron el mayor promedio al ser cultivadas con 5
y 10 semillas sitio-1. 5) La materia seca fue el único componente que estuvo relacionado con el rendimiento de grano
The following research work "agronomic evaluation in SICA of three varieties of rice (oryza sativa L.) with different quantities of seeds" was carried out on the premises of the University Citadel "Dr. Salvador Allende "of the University of Guayaquil. The objectives were: 1) To evaluate the agronomic behavior of three cultivated rice varieties with three quantities of seeds per sowing site. 2) Determine the best agronomic components that influence grain yield. The factors under study were the three rice varieties INIAP 14, INIAP 18 and SFL-11 and three quantities of seeds, whose results regarding the agronomic variables were analyzed according to the experimental fully randomized design, with factorial arrangement A x B with three replicates And nine treatments. The conclusions of the present study were: 1) The variety INIAP-14 and INIAP-18 presented the highest average weight of 1000 seeds. 2) The INIAP-14 variety was the best one in terms of plant height average, panicle length and paniculata-1 and grains in INIAP-18 and SFL-11 varieties. 3) with th of a site -1 seed, a higher plant height, panicle length and panicula were obtained. 4) The number of tillers plant-1, panicle per plant and weight of 1000 seeds were better when they were cultivated with 5 and 10 seeds per site-1. 5) Dry aerial biomass was the only component that was relating to grain yield.
