Creole potato (Solanum phureja Just et Buk) behavior to calcium anda boron in a soil of Cundinamarca, Colombia
At Funza, Cundinamarca, Colombia, in a soil derived from volcanic ashes, classified as Typic Dystrandept, the effect of Calcium and Boron applications and its interactions on yield and tuber quality of the creole potato was evaluated. A complete randomized block design with factorial arrangements, two factors and fore levels was used for a total of 48 experimental units of 20m2 each. The levels of Ca were 0-18-36-54kg/ha and those of B 0, 05, 1, 1.5kg/ha. Total yield and tuber size, as well as tuber density and humidity and the economic analysis were evaluated. The results showed a significant effect of the treatments on the total yield, being the highest, obtained with 18 and 54kg Ca/ha and 1kg B/ha with 18kg Ca/ha, 29.7, 30.2 y 22.5 t/ha, respectively. No effect on tuber size was observed, but the production was mainly of the first class size. The highest marginal incomes were obtained with calcium alone, 1kg of B and 18kg of Ca, and 1kg of B and 36 of Ca. The boron levels, 0.5, 1.0 and 1.5 without Ca produced marginal incomes of $253.400, $502.000 and $885.000, respectively. Although no significant increase of the tuber density was obtained, in comparison with the check, for the combinations of 0.5kg/ha of B and the Ca levels, an increase was observed, indicating the necessity of the presence of B with Ca.
