Resumen
Descripción
En el Centro Regional de lnvestigaciones Agrícolas "Nataima", situado a 431
m.s.n.m. con una temperatura promedio de 28°C y una precipitación anual de 1288
mm, se realizó un experimento para determinar los períodos en los cuales el sorgo
usa más eficientemente el agua; tres materiales de sorgo fueron utilizados, así como
siete tratamientos que combinan épocas de humedad adecuada en el suelo. Un diseño experimental de parcelas divididas y tres repeticiones fue utilizado.De acuerdo
a los resultados obtenidos, Ia época critica de deficit hídrico es diferente para cada
material, lo cual permite una mejor planificación de las épocas de siembra y oportunidad de aplicación de riego para lograr buenos rendimientos y una mejor rentabilidad.
A study was carried out at ICA's regional Agricultural Research Centre "Nataima", located at 431 meters above sea level, with 28°C of average temperature and 1288 mm annual rainfall. The objective of this research was to determine the periods of better water use by the Sorghum crop. Three Sorghum genotypes were used as well as seven treatments which combine periods of adequate soil moisture. An experimental design of split plots with three replications was used. The results showed that the critical periods of moisture deficit are different for each genotype; this allows to do a better planning of planting dates and irrigation applications in order to obtain high yields and a better gross margin.
