Low levels of ferredoxin, ATP and leghemoglobin contribute to limited N2 fixation of peas (Pisum sativum L.) and alfalfa (Medicago sativa L.) under S deficiency conditions

Rhizobium inoculation and sulphur fertilizer improved yield, nutrients uptake and protein quality of soybean (Glysine max L.) varieties on Nitisols of Assosa area, Western Ethiopia

“…Rhizobium strain treatments to soybean significantly increased seed weight per plant either alone or in combination with S. Each Rhizobium strain has own synergetic effect on production of seed weight as seed weight also increased when Rhizobium strains (significantly greater for MAR-1495) were applied individually but greater in combination with S. That shows S application is important nutritional element to get better soybean yield. Similarly, results for beneficial effect of S and Rhizobium strain application on yield and yield attributing characteristics have also been recorded by other workers (Habtemichial et al, 2007;Scherer et al, 2008). This study revealed that Rhizobium inoculation with S fertilizer increased sufficient yield of quality soybean seed.…”

“…Nitrogen fixing capacity of leguminous plants can be increased by the supply of adequate amounts of nutrients such as S. S is a vital part of the ferredoxin, an iron-S protein occurring in the chloroplasts. Ferredoxin has a significant role in NO 2 and sulphate reduction, the assimilation of N by root nodule bacteria and frees living N-fixing soil bacteria (Scherer et al, 2008). A study revealed lower N accumulation and a yield reduction of legumes when S was limiting (Scherer et al, 2006) and also recognized as a limiting factor not only for crop growth and seed yield but also for quality of products (Jemal et al, 2010).…”

Functional plasticity of Trifolium repens L. in response to sulphur and nitrogen availability

“…Similarly, and in accordance with Scherer et al (2008) who observed that the amount of leghaemoglobin was reduced by S deficiency in peas and alfalfa, when no S was added, nodules devoid of leghaemoglobin were more numerous. Because leghaemoglobin regulates the supply of oxygen to the nodule tissues, it allows nitrogenase activity.…”

Effect of Soybean (Glycine max) Seed Inoculation with Liquid and Carrier Based Rhizobium cultures and Phosphorus Levels on Productivity and Physico-Chemical Properties of Soil

“…Highly effective and competitive Rhizobium strains and a supply of appropriate amount of phosphorus (Scherer et al, 2008) could markedly increase legume growth and N fixation.…”
