Effects of water stress on grain yield in the vegetative phase of bean cultivation
The experiment was carried out in the UCTB Los Palacios from 2010 to 2012, in Hydromorphic Gley Nodular Ferruginous Petroferric soil, from November to February in semicontrolled conditions, in 1m2 flowerpot stands of area. In each flowerpot, 40 seeds of Delicia 364 variety were sowed with the object...

Zusammenfassung: | The experiment was carried out in the UCTB Los Palacios from 2010 to 2012, in Hydromorphic Gley Nodular Ferruginous Petroferric soil, from November to February in semicontrolled conditions, in 1m2 flowerpot stands of area. In each flowerpot, 40 seeds of Delicia 364 variety were sowed with the objective of evaluating the response of the bean subjected to different intensities of water stress in the vegetative phase and their effect in the yield. The results demonstrated that when bean cultivation in the vegetative phase is subjected to water stress with different intensities, increments in the yield were obtained in relation to the control that was maintained with normal irrigation. Different intensities of water stress in the vegetative phase incremented the yield. Keywords: irrigation, soil, water, green house. El experimento se condujo en la Unidad Cientifico Tecnologica Los Palacios (UCTB Los Palacios), desde el ano 2010 hasta el 2012, sobre un suelo Hidromorfico Gley Nodular Ferruginoso Petroferrico durante el periodo de noviembre a febrero en condiciones semicontroladas, en maceteros de 1 [m.sup.2] de area. En cada macetero se sembraron 40 semillas de la variedad Delicia 364, con el objetivo de evaluar la respuesta del frijol sometido a diferentes intensidades de estres de agua en la fase vegetativa y su efecto en el rendimiento. Los resultados demostraron que al cultivo de frijol en la fase vegetativa al someterlo a estres hidrico permitio incremento en el rendimiento a favor de los tratamientos con estres respecto al testigo que se mantuvo con riego normal. Diferentes intensidades de estres de agua en la fase vegetativa incremento el rendimiento. Palabras clave: riego, suelo, agua, invernadero. |
