Growing soybeans is one of the main activities in the current agricultural sector. For proper development of the plant and consequent to achieve the maximum production potential, adequate conditions of fertility composition of the soil must be provided. In this scenario the organic fertilization assumes an important role, either partially or totally replacing inorganic fertilization, seeking better viability of the activity, as well as being an alternative to disposal of waste compounds produced by livestock activities. The main purpose of this study was to evaluate the possible relationship between the nodulation ability in the soybean plant, cultivated with different dosages of aviary bed, as well as on their ultimate performance in terms of income. The trial was carried out at UTFPR research farm, Câmpus Pato Branco, from November/2014 up to March/2015. Four application times were tested at 45, 30, 15 and 0 days prior to wheat sowing with soyabean as a predecessor crop, and, in the sub-plots, doses of 0, 3,2, 6,4, and 9,6 t ha of aviary bed were applied on a dry base. The aviary bed did not limited nodulation in soybean plants. Even in the control treatment, without the use of aviary bed, the nodulation was not expressive, due to the absence of intentional inoculation with selected strains, leaving the native strains the function of infection and nodular development. The aviary bed increased the height of plants, the weight of a thousand seeds and the yield of soybean grains. |
