Influência do biofertilizante liquído aplicado ao solo, no crescimento e produção da beterraba (Beta vulgaris L.).

Abstract

The transformation of current agricultural production in a sustainable and productive way is characterized as one of the greatest challenges of our time. The transition from conventional management to more sustainable ones is an alternative of transformation, in which the plants become more dependent on the microbial interactions, being a key factor in the control of productivity and quality in agricultural ecosystems. Based on this information it is proposed to study five doses of biofertilizer applied via soil. The experiment was conducted from May to June 2018, under field conditions in the randomized block design. The treatments consisted of five doses of the biofertilizer and a mineral fertilization: D1 = one third of the recommended dose of potassium; D2 = two thirds of the recommended dose of potassium; D3 = the recommended dose of potassium; D4 = 1.3 times the recommended dose of potassium and D5 = 1.6 times the recommended dose of potassium; and D6 = mineral fertilization, without the use of biofertilizante.com four replicates. Fertilization with biofertilizer was based on the recommended dose of potassium applied via soil. The variables analyzed were: total root production, commercial root production, number of leaves and shoot height, root diameter, fresh and dry mass of roots and leaves. The doses of biofertilizers D3 and D5, corresponding to the potassium dose of 80 and 128 kg ha-1, were higher when compared to the others. The increment promoted by the biofertilizer was beneficial to the production of dry mass of beet plants.
