Symbiotic Properties

Rhizobium japonicum strain evaluation experiments with soybean (Glycine max) confirmed that strain CB1809 was ineffective in nitrogen fixation with the related cultivars Hardee and Geduld but was highly effective with cv. Hampton. There were no major symbiotic differences between the cultivars with other strains. Three strains including CB1809 were used, singly, in pairs, or all together, as inocula for Hardee and Hampton in competition studies in the field. The ratio of strains recovered from nodules was used as an index of competitive success. A few nodules contained more than one strain. There was a marked host x strain interaction in nodulating competitiveness related to symbiotic effectiveness, the order of competitive success being CB1809 > CC709 > CB1795 for Hampton and CC709 > CB1795 > CB1809 for Hardee. With Hardee, strain CB1809, although unsuccessful itself in forming nodules in the presence of the other inocula, appeared to suppress nodule formation by those strains. Nodulation by CB1795 in the presence of CB1809 was suppressed to such an extent that plant growth was retarded and not different from that of uninoculated control plants, although CB1795 alone nodulated Hardee abundantly and effectively. There was no evidence that naturally-occurring ineffective R. japonicum posed any competitive threat to the nodulating ability of effective inoculant strains.

The natural resources of the coastal area in Indonesia have the potential to be developed as an agricultural land with the support of both cultivation technology and land processing,  which one of them was done by using Rhizobium japonicum bacteria to meet the need of nitrogen in the soybean plants. This study aimed to determine the characteristics of nitrogen fixation in various soybean cultivars planted in the coastal area. The research was conducted in Mancingan, Parangtritis, Kretek, Bantul, DIY. The study was designed in Completely Randomized Design which consisted of two factors and was repeated three times. Factor I was Rhizobium japonicum inoculation (with inoculation and without inoculation); factor II was 10 various cultivars of soybean (Grobogan, Burangrang, Argomulyo, Anjasmara, Dena 1, Gema, Kaba, Wilis, Sinabung, Gepak Kuning). The results showed that the inoculation of Rhizobium japonicum in soybean cultivars in a coastal area could increase the number of root nodule, dry weight of root nodule, dry seed weight per plant, and harvest index. Burangrang cultivar planted in the coastal area was the most responsive to Rhizobium japonicum inoculation among other soybean cultivars tested.

Abstract Root hairs of soybeans (Glycine max), target cells for infection by Rhizobium japonicum accumulate iron more than 10-fold, cobalt more than 8-fold and calcium more than 7-fold compared to the other parts of the root system. In root hairs of wheat (Triticum aestivum) a much smaller accumulation of these elements was found. The symbiont of Glycine max, Rhizobium japonicum, is known to have a high requirement for iron, cobalt and calcium.

Nodule Efficiency

Soybeans (Glycine max (L.) Merrill) often do not give yield responses to added fertilizer nitrogen (N) because high soil N levels inhibit fixation of atmospheric N2. Yield responses to N fertilizer applied at planting usually indicate that N2 fixation is less than optimal. The effects of inoculation with Rhizobium japonicum, and fertilizer N levels, on soybean N2(C2H2) fixation and seed yields in Ontario were investigated in ’ 1976 and 1977. Three locations were used each year, representing areas where soybeans had been grown for many years (Ridgetown), for only a few years (Elora), or not at all (Woodstock). Treatments were (a) Uninoculated + 0 N, (b–e) Inoculated + 0, 50, 100 or 200 kg N/ha. Results indicated that inoculation increased seed yields only when soybeans were introduced into new areas. Fertilizer N applications at planting time did not increase yields in areas where soybeans had been grown several times previously, indicating that N2 fixation could support maximum yields. Nodule number and mass, and N2(C2H2) fixation rates were all decreased by fertilizer N. An increase in nodule efficiency, later in the season, in high N treatments was most marked at Ridgetown.

Applied Nitrogen

In field experiments with soybeans (Glycine max) conducted over four seasons at Hermitage Research Station, Queensland, levels of applied nitrogen (as urea) up to 134 kg ha -1 were examined. Nodulated soybeans failed to respond to applied nitrogen in three out of the four seasons. A response was obtained in one season when abnormal climatic conditions of low rainfall and high temperatures resulted in a comparatively lower level of nodulation. The probability of such a response is discussed in relation to climatic data of the area over the past 108 years. Nodulation and nitrogen fertilizer increased seed size and nitrogen content of the seed in soils free of Rhizobium japonicum but nitrogen fertilizer had little effect on these characteristics in soils carrying R. japonicum. Oil content of the seed was negatively correlated with the nitrogen content in rhizobia-free soils. Nitrogen fertilizer had a depressive effect on nodulation. This effect was severe when inoculated soybeans were grown in soil free of R. japonicum particularly under conditions of declining soil moisture and high temperatures. In soils with R. japonicum the depressive effect was comparatively light.
