TORTA DE FILTRO E MICRONUTRIENTES NO PLANTIO DE CANA-DE-AÇÚCAR

The objective of this work was to evaluate the response of the sugarcane crop to the mineral fertilization, filter cake and Nutry Cana Micronutrientes, in the planting groove and foliar route. The experiment was conducted in a randomized block, where five treatments were established (T0, T2, T3, T4 and T5) with five replications. The development of the crop was evaluated at 30, 60, 90 and 120 days after planting, and the productivity 12 months after planting, during which period the physiological maturation of the crop is understood. It was possible to reach high yields of sugarcane reducing the recommended dose of mineral fertilizers, complementing with the organic fertilization from the filter cake, and the application of micronutrients via tolete and foliar route. The sugarcane showed a positive response to the joint application of these fertilizers, where a gain of 27.6 kg in the stems per linear meter in the T5 treatment was verified, maximizing the effect on the productivity and reducing the costs with mineral fertilizers.
