MONTERO, L; DUARTE, Carmen; CUN, R  and  CABRERA, J. A. Efectividad de biofertilizantes micorrízicos en el rendimiento del pimiento (Capsicum annuum L. var. Verano 1) cultivado EN diferentes condiciones de humedad del sustrato. cultrop [online]. 2010, vol.31, n.3, pp.00-00. ISSN 0258-5936.

The application of arbuscular mycorhizal fungi was evaluated as a biofertilization alternative in organoponics as well as its effect on pepper yield at different substrate moisture levels. Since the beginning of flowering-fruiting, when 20 % of plants had flowers, two irrigation variants were settled, which consisted of applying water when substrate moisture decreased to 65 and 90 % of the container capacity (Cc). The inoculations with Glomus hoi-like and Glomus mosseae strains increased the yield of pepper fruit weight, compared to the non-inoculated control, between 12 and 24 % in the treatment of lower moisture content (65 % Cc) whereas between 10 and 20 % in the other of greater water supply (90 % Cc) of the substrate. A higher yield was obtained by Glomus mosseae at different substrate moisture levels.

Keywords : mycorhizae; irrigation; organoponics.
