Item Evaluación de yodo agrícola como biofortificante en el cultivo de mora (Rubus glaucus Benth)(2022-09) Garcés Montero, Carmen Marisol; Zurita Vásquez, José HernánCrop biofortification is an alternative to improve production and the food chain for humans because food is ingested and mineralized elements come from fruits, vegetables, as well as products from animals. In this way, by increasing the mineral value of iodine from a conventional crop, it is a significant option to solve the deficient intake of iodine that causes disorders such as TDI and thyroid disorders. The blackberry (Rubus glaucus Benth) is a fruit consumed nationally and produced in the Sierra region, which is why in this investigation the application of 0.5 L in drench and foliar approximately with three different doses of agricultural iodine was evaluated. Three applications were made with intervals of 14 days and the results were obtained after 51 days. The average value of 4,372 inflorescences per plant was significant when applying a dose of 2 cm³/L of agricultural iodine in drench, likewise, in foliar application and drench with the same dose, the continuous weight increase of the fruits with values of 1199 and 1095 g respectively. The postharvest of the fruits was evaluated in days, the drench treatments at doses of 2 and 3 cm³/L obtained superior results with an average of 3.33 days. The Brix index was evaluated, but the results showed that agricultural iodine does not produce a change. On the other hand, the content of chlorophyll in the blackberry leaves was significantly positive with a difference of 1,676 µg/g when applying 2 cm³/L of agricultural iodine in drench between the treatment and the control. And finally, diseases such as Botrytis and Oidio sp. They commonly affect this crop by reducing its production. When applying agricultural iodine, the lowest percentage of infection was in Botrytis
