“…Thus, molybdenum is the key to nitrogen fixation by legumes. Brkics et al (2004) and Jongruaysup et al (1993) also stated that the application of molybdenum stimulated nodulation and biological nitrogen fixation, thus increasing the legume yield. Moreover, Katyal and Randhawa (1983) stated that molybdenum is required in the synthesis of ascorbic acid is implicated in making iron physiologically available.…”

“…Hageman and Burris (1978) reported that the enzyme nitrogenase contained two proteins: Mo-Fe protein (component containing molybdenum, iron and protein) and Fe protein (component containing iron and protein). Jongruaysup et al (1993) stated that crops developing symbiosis with rhizobium bacteria had increased molybdenum requirements. Deficiency of this element causes a reduction of nodulation, leghaemoglobin concentration and nodule dry weight.…”

The influence of seed inoculation with a bio-preparation of nodule bacteria Rhizobium leguminosarum, fertilization of 0, 40, 80, 120 kg N/ha and molybdenum topdressing on the yield of green mass, dry ma�er, seed, average number of pods per plant, average number of seeds per pod, average nodule number per plant, nodule dry weight as well as plant and seed protein concentration were studied during the two years of investigations on two soils -Mollic Gleysols and Eutric Cambisols. The highest values of all investigated parameters were obtained in the inoculated seed variants with molybdenum application, except the average nodule number per plant where the highest values were achieved in variants without molybdenum. The effect of nitrogen fertilization depended on the soil type, i.e. its chemical properties. The largest number of the investigated parameters obtained the highest values as a result of fertilization with 40 kg N/ha on Mollic Gleysols (3.96% humus). Thus, seed yield was 4.02 t/ha, nodule dry ma�er 0.482 g per plant whereas seed protein concentration was 26.91%. The largest number of the investigated parameters on Eutric Cambisols (1.07% humus) obtained the highest values with fertilization of 80 kg N/ha where seed yield amounted to 3.65 t/ha, nodule dry ma�er 0.456 g per plant while seed protein concentration was 26.48%.

In legumes, both increases and decreases in nodule number in response to Mo deficiency have been reported, but reasons for the different responses have not been proposed. The present study examined nodule initiation and development in black gram seedlings using two levels of seed Mo to induce Mo deficiency. In the first 11 days after inoculation, low levels of Mo in seed had no effect on nodule initiation or the number of nodules. At 13 days after inoculation, low Mo in seed depressed bacteroid concentration, leghaemoglobin concentration, nodule number and nodule fresh weight. Acetylene reduction activity was delayed by 2 days in plants grown from low Mo seed. We suggest that the delay in N 2 fixation in plants grown from low Mo seed was due to slower incorporation of Mo of soil origin into nitrogenase. We further suggest that restricted supply of essential metabolites to the nodules on plants from low Mo seed resulted in the slower maturation of early initiated nodules and the repression of formation of new nodules.
