Soybean yields can be considerably improved by inoculation with selected Bradyrhizobium japonicum strains and fertilization. The aim of this study was to assess the productivity of two soybean cultivars depending on the applied N mineral fertilizers and seed inoculation with B. japonicum. The study showed that on average, for both cultivars, the soybean yield was most favorably affected by the combined use of inoculation and nitrogen fertilization (increase in seed yield by 42%, protein yield by about 28%). The application of mineral nitrogen at the dose of 30 or 60 kg·ha−1 allowed the increase in the seed yield by about 17% and protein content by about 14% compared to the control. Inoculation of soybean seeds with B. japonicum increased the yield of soybeans by about 20%, proteins by about 10% compared to the control, and inoculation of Hi®Stick Soy favored a better yield than Nitragina. Inoculation of seeds with Nitragina or Hi®Stick Soy and fertilization with mineral nitrogen increased the content of protein and fiber in seeds of both soybean cultivars, as well as reduced the amount of ash and fat. The seeds of cv. Aldana had a higher amount of protein and ash than cv. Annushka, but a similar amount of fat and fiber.

A growing interest in soybean cultivation in Poland has been observed in the recent years, however it faces a lot of difficulties resulting from a poorly understood effectiveness of plant nitrogen fertilization and from the introduction of Bradyrhizobium japonicum to the environment. The aim of the study was to evaluate the consistency of response of two soybean cultivars to three different rates of mineral N fertilization and two seed inoculation treatments with B. japonicum in field conditions over four years regardless of previous B. japonicum presence in the soil. A highly-diversified-over-years rainfall and temperature in the growing season do not allow for a definite statement of the differences resulting from seed inoculation and mineral N fertilization applied separately or jointly in soybean. A high sensitivity of the nodulation process to rainfall deficits was noted, which resulted in a decreased amount of B. japonicum DNA measured in qPCR and dry matter of nodules. ‘Annushka’ demonstrated a higher yield of seeds and protein, higher plants and the 1st pod setting. ‘Aldana’, due to a significant decrease in plant density, produced a higher number of pods, seeds per pod and the 1000 seed weight per plant. Both cultivars responded with an increase in the seed yield after seed inoculation with HiStick, also with an application of 30 and 60 kg N, as well as with Nitragina with 60 kg N.

Soybeans (Glycine max [L.] Merrill cv. Forrest) were grown under irrigation on a well-structured grey clay soil, previously free of Bradyrhizobium japonicum and containing relatively high levels of mineral N, at Trangie, N.S.W. There were two soil pretreatments, pre-cropped (which had the effect of reducing the level of mineral nitrogen in the soil) and pre-fallowed, and four rates of inoculation (B. japonicum CB 1809 - nil, 0.01 X, 1.OX [=normal] and 100X).Mineral nitrogen (0-10 cm) initially was higher in pre-fallowed soil than in pre-cropped soil (37.6 v. 18.5 mg N per kg). Depletion of mineral nitrogen occurred more rapidly in pre-fallowed treatments, so that, 7 days after harvest, mineral-N in pre-cropped soil was significantly higher than in pre-fallowed soil (14.4 v. 10.6 mg per kg).With high levels of soil mineral nitrogen, colonization of seedling rhizospheres by rhizobia and plant nodulation were diminished. These effects were ameliorated but not eliminated by increased rates of inoculation. The development of the symbiosis was also impeded by lower rates of inoculation (0.01 X, 1.OX).

The aim of the study was to assess soybean response to sowing material inoculation with HiStick® Soy preparation, containing Bradyrhizobium japonicum. Based on the obtained results, it was found that the inoculation significantly increased the number and dry weight of nodules on soybean roots compared to control. The bacterial preparation significantly increased the number of pods per plant. As a result, a significant increase in seed yield (0.58 t/ha) was obtained compared to control. HiStick® Soy increased total protein content in seeds. Protein and fat yield was higher after seed inoculation by 318 kg/ha and 101 kg/ha, respectively, compared to control.

Commercial Inoculants

In the absence of Bradyrhizobium japonicum populations in the soil, yields of field-grown soybean (Glycine max (L.) Merrill) usually respond to inoculation with B. japonicum. The objective of this research was to determine the relationship between numbers of B. japonicum per seed in inoculants and soybean nodulation and yield. A total of six field experiments were conducted in 1989 and 1990 on new soybean soils. In dilution trials, Grip inoculant was applied to provide approximately 106, 105, 104, and 103B. japonicum per seed at two locations in 1989. Nodule number and mass, as well as seed yield, increased curvilinearly upward with increasing log10 most probable numbers (MPNs) of B. japonicum. The yield response curve was best fit by a cubic equation, which accounted for 97% of the variation in yield. Seed yields increased 19% (1.83 to 2.13 Mg/ha) from 105 to 106B. japonicum per seed. In field experiments involving 8 commercial inoculants in 1989 and 10 in 1990, and conducted at two locations in each year, responses to increasing log MPNs in the inoculants also were concave upwards and cubic. In the two years, 78 and 46% of the yield variation was accounted for by log MPN per seed. Increasing MPN per seed from 105 to 106 improved yields in first-time fields by an average of 24%, indicating the present minimum standard of 105B. japonicum per seed should be increased. Key words: most probable numbers, response to inoculation, nodulation, Glycine max (L.) Merrill.

A field experiment was carried out with three bacterial inoculants: HiStick® Soy, Nitragina, Nitrazon and the control. Number and dry weight of nodules were significantly higher with inoculation of bacterial inoculants compared to the control. In 2017, the most pods per plant were obtained after the use of Nitrazon or HiStick® Soy, while in 2018, after the use of HiStick® Soy or Nitragina. In 2018, the highest 1000 seed weight was obtained after the use of Nitragina. In 2017, the seed yield was the most favourably affected by the inoculants HiStick®Soy (3.31 t ha-1) and Nitrazon (3.37 t ha-1) and in 2018, by HiStick® Soy (3.92 t ha-1) and Nitragina (3.87 t ha-1). High Soil Plant Analysis Development (SPAD) and Leaf Area Index (LAI) readings, were observed with HiStick® Soy.

The effect of different systems of N fertilization on nitrogen balance and N transformation in the soil was studied in long-term stationary experiments (1991–2002) with successive growing of maize. Average dry matter yield for the control without fertilization in the period 1991–2002 was 11.67 t of dry matter per ha, which was by 2–2.9 t less than for fertilization treatments. Statistically significant differences between the control and fertilization treatments were determined for the first time in the 4th experimental year. Average nitrogen uptake by the aboveground biomass was116 kgN/ha for the control, 162–170 kg N/ha for fertilization treatments. All experimental treatments had a negative balance of N inputs and outputs, and it was –1394 kg N/ha for the control (for 12 experimental years). After the application of mineral fertilizers, a lower content of total carbon and nitrogen was measured in the topsoil compared to the control and treatments with organic fertilization. The changes in the nitrogen regime of soil were characterized by the content of extractable nitrogen and carbon in extractions by 0.01M CaCl2. With respect to the content of mineral nitrogen and easily extractable organic nitrogen and carbon in the topsoil the control was most stable followed by farmyard manure treatment. Soil lysimeters were installed in these experiments (depth60 cm, size0.2 m2). For an eight-year period (1994/2002)11.78 kgN-NO3–/ha were determined in lysimetric waters. These values for fertilization treatments ranged from 21.0 to58.2 kgN-NO3–/ha. Straw application reduced nitrate contents in lysimetric waters.

Soybean [Glycine max (L.) Merr.] has long been used as a forage crop but its morphological development and forage potential have not been studied extensively. A study was conducted using oilseed soybean cultivars of different maturity to determine their morphological development, forage yield, seed components and seed yield at the University of Ankara, Turkey. Five soybean cultivars OAC Salem (earliest), OAC Bayfield (midearly), OAC Eclipse (mid-early but later than OAC Bayfield), OAC Glencoe (full-season soybean) and SA.88 (late), were used in the study conducted in 2000 and 2001. The full-season cultivar OAC Glencoe was the tallest cultivar, and had the highest levels of fresh and dry matter yield and crude protein yield among soybean cultivars in both years. Therefore, OAC Glencoe is considered to be the most suitable soybean cultivar for forage production when intercropped with corn in Ankara region of Turkey. However, attention should be given to the earliest maturing cultivar OAC Salem that had the highest seed yield and better relative seed composition of all the cultivars.
