Resumen
La investigación se llevó a cabo en la finca del ingeniero Wilman García, ubicada en Ventanas, provincia de Los Ríos, y presentó el siguiente objetivo general: evaluar el comportamiento agronómico de varias líneas promisorias de soya, en comparación con testigos locales en la zona de Ventanas, provincia de Los Ríos. Como objetivos específicos se tuvieron los siguientes: a) evaluar las características agronómicas de los cultivares en estudio. b) Seleccionar las líneas con mejores características agronómicas y de rendimiento de entre los materiales en estudio.
Se empleó el diseño de bloques completos al azar, con tres repeticiones. Para determinar las diferencias entre promedios se utilizó la prueba de Duncan al 5 % de probabilidad.
Entre las variables evaluadas estuvieron días a la floración, días a la cosecha, altura de planta, semillas por vaina, peso de 100 semillas, rajadura de testa, moteado y rendimiento (kg.ha-1).
Una vez realizados los análisis respectivos, se pudo concluir lo siguiente: 1) prácticamente todos los tratamientos mostraron una buena adaptabilidad a la zona de Ventanas, ya que presentaron buenas características agronómicas; y, 2) los tratamientos INIAP-308, 10564, S-869 y S-855 tuvieron rendimientos similares estadísticamente; alcanzaron promedios de 3555; 3518,67; 3311,33 y 3085,0 kg.ha-1, respectivamente. Se evidenció que el tratamiento testigo INIAP-308 tiene características iguales o superiores a los demás tratamientos evaluados.
The research placed Wilman García was completed in the Engineer's Land in Ventanas, province of Los Ríos, presenting as general objective: Asses the agronomic behavior of several promissing lines of soya in comparison of local witnesses in the zone of Ventanas, province of Los Ríos, and as specific objectives the following: a) Evaluate the agronomic features of them you will cultivate in study. b) Select the lines with better agronomic features and of performance out of the materials in study. In the present research he used the Complete Block design at random, with three repetitions. To determine the differences between stockings the test from Duncan to the 5 % from likelihood was used. Between the evaluated variables they were: days to the flowering, days to the harvest, plant height, seeds by sheath, 100 seed weight, crack of moteado and performance makes a will (kg.ha-1). Once made finishing the following was possible the respective analyses: 1) All treatments showed a good adaptability to the Ventanas zone, practically because they presented good features agronomic. And 2) Los INIAP 308, 10564, treatments, S – 869 and S – 855 had similar performances reaching averages of 3555 statistically; 3518,67; 3311,33 and 3085,0 kg.ha-1, respectively, showing that the treatment INIAP 308 witness has similar or above the other evaluated treatments features
