ALVAREZ MARES, Vicente et al. Formulations and dose effectiveness of calcium pimento performance. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.7, pp.1689-1699. ISSN 2007-0934.

In order to know the effectiveness of formulations (CaNO3)2 líq, (CaNO3)2 sol-1, (CaNO3)2 sol-2 and (CaNO3)2 sol-3 as well as the most appropriate dose of each formulation, to induce greater fruit yield in bell pepper (Capsicum annuum L.), research was conducted in a chapel-type greenhouse, transplanting a plant plastic pot with a capacity of12 L, in which doses were applied of 21, 20 , 19, 18, 17, 16 and 15 L ha-1 with each formulation solution. The experimental design was randomized complete block with three replicates per treatment. The most appropriate formulations were of (CaNO3)2 líq and (CaNO3)2 sol-1, since the first caused the dry weight of fruits was increased 24.5, 31.9 and 44.4% compared to that obtained with formulations (CaNO3)2 sol-1, (CaNO3)2 sol-2 and (CaNO3)2 sol-3, respectively. While the (CaNO3)2 sol-1 increases were 5.9% compared to that achieved with (CaNO3)2 sol-2 and 15.9% compared to that obtained with (CaNO3)2 sol-3. So that the yield of plants with (CaNO3)2 líq exceeded the respective 11.2, 26.8 and 60.8% at the averages were obtained (CaNO3)2 sol-1, (CaNO3)2 sol-2 and (CaNO3)2 sol-3, respectively. Based on the dry weight of fruit, the most appropriate doses were 17, 15, 18 and 19 L ha-1, in the order of the formulations of calcium above, but with 15 and 17 L ha-1 more influence had in agricultural sustainability.
