VIEIRA NETO, Santiel Alves et al. Forms of inoculant application and effects on soybean nodulation. Rev. Bras. Ciênc. Solo [online]. 2008, vol.32, n.2, pp.861-870. ISSN 1806-9657.

Nowadays, inoculant application in the sowing furrow of soybean is widely used, but there is little information underlying this practice, which would prove the efficiency in different environments under no-tillage systems. This study aimed to evaluate the viability of inoculant application to soybean, via seed and in-furrow, in soil never cultivated with soybean or previously cultivated with soybean. Two field experiments were carried out as of December 2004 in a Red Yellow Latosol (Oxisol), using the same methodology and applying the same treatments, at two different sites, with or without previous soybean cultivation. Eight treatments were tested: (1) seed inoculation (inoculant + fungicide + micronutrient), (2) without inoculation (fungicide + micronutrient), (3) control (pure seed without treatment), (4) in-furrow application dose 1 (recommended dose of inoculant in the furrow), (5) in-furrow application dose 2 (the double of the recommended dose in the furrow), (6) furrow application dose 3 (three times the recommended dose in the furrow), (7) furrow-dose 1 + seed inoculation, and (8) N fertilization (200 kg ha-1 N). The dry matter mass of the nodules, the number of total nodules and viable and non-viable nodules were evaluated 30 and 75 days after emergence. The treatment inoculant + fungicide + micronutrient application via seed in the non-cultivated soil resulted in the best nodulation. In the soil previously cultivated with soybean, the treatments with the simple and double inoculant dose in the furrow reached the best results. Nodule dry mass was the lowest in the treatment with mineral fertilization. In-furrow application of the inoculant seemed a viable practice due to the similarity of the results with traditional seed inoculation.
