POLON-PEREZ, Ricardo; CASTILLO-TORO, Dámaso; MIRANDA-CABALLERO, Alexander y RUIZ-SANCHEZ, Michel. Water Stress Effects on Grain Quality in the Cultivation of Rice (Oryza sativa L.). Rev Cie Téc Agr [online]. 2018, vol.27, n.3 ISSN 2071-0054.
The experiment performed in UCTB Los Palacios from 2014 to 2017, on Hydromorphic Gley Nodular Ferruginous Petroferric soil, in order to know the effect of water stress on grain quality with a middle cycle rice variety. Results showed that in the new variants of water management, a bigger percent of white entire grains was obtained. It oscillated between 55,9 and 65,3 %, while in the traditional management (control) the lowest percent of white entire grains was obtained ( between 48,3 and 50,5 %), with a bigger quantity of chalky grains (with white belly) and fissures in the grains. However, with the new variants of water management the percentage of grains with white belly and fissures was lower than with the traditional water management being these last unfavorable elements, one of the reasons why some varieties could not continue in the national rice production.
