| Popis: | The use of the ecological fertilizer foliar HerbaGreen in the cultivation of potato, Ajiba variety, combined with different levels of chemical fertilization (NPK) was evaluated. The research was carried out at UBPC “La Rosita”, corresponding to the “Vladimir Ilich Lenin” Crop Company, in the municipality of Jovellanos, Matanzas province. Four fertilization treatments were established (25, 50, 75 and 100 % of the NPK dose) plus the application of the HerbaGreen product at a dose of 1 kg ha-1 in 200 L of water, in addition to the control (100 % NPK Without the ecological fertilizer). Three applications were made during the biological cycle of the crop. From the leaves, stems and roots, was determined the concentration of starch, carbohydrates and total soluble protein and starch concentrations in tuber yield and its components. The use of the HerbaGreen allowed reducing the amounts of chemical fertilizer in the potato crop. The treatment of 100 % of NPK plus the HerbaGreen product showed significantly higher yields than the other treatments. |
