Inoculación con (Bradyrhizobium japonicum) sobre la nodulación de semillas de soya variedad SSK (Glycine max) Quevedo-Los Ríos, 2013

This research work was carried out during the dry season of the year 2013 - 2014 in the Jacome family Villa, located at Km 1.5 via Quevedo - San Carlos 400 m Prefectural Zona Norte, Quevedo, Ecuador.The objective was to evaluate the inoculation with Bradyrhizobium japonicum in soybean variety SSK, the inoculum used was Nitragin that is a dry substance containing Bradyrhizobium.The treatments used were ground with a history of soybean soil with a history of more soybean inoculant sterile substrate with substrate plus inoculant. For this fieldwork pots were used, formed and aligned at a distance of 0.75 m from one another, to walk among them and allow easy handling. Experimental design was utilized completely randomized, with six replications and four treatments, to determine differences between treatment means; the Tukey test (P ≤ 0.05) was applied. The variables evaluated were: days to germination, germination percentage, number of root nodules, large number of nodes, number of middle nodes, number of small nodules, and nodule fresh weight of 100 and infectivity of the nodules. In the days to germination, germination percentage, number of nodules per root, number of large nodules, number of middle nodes, number of small nodules, and weighing 100 fresh nodules, no statistical difference in infectivity, there was no statistical difference significant.Treating soil with a history over the soy inoculant, was superior to the other treatments resulting in greater number and size of nodules per root nodules. KEYWORDS. Inoculant, nodule, root, nodulation, rhizobia, inoculation, soybean.
