Performances of Mungbean Varieties as Affected by Rhizobium Inoculants

抄録

The effects of Rhizobium inoculation on the nodulation, plant growth, yield attributes, seed and stover yields, and seed protein content of six mungbean [Vigna radiata (L.) Wilczek] varieties were investigated. The mungbean varieties were BARI Mung-2, BARI Mung-3, BARI Mung-4, BARI Mung-5, BINA Moog-2 and BU Mung-1. Rhizobium strains TAL169 and TAL441 were used for inoculation of the seeds. Two-thirds of seeds of each variety were inoculated with Rizobium inoculant and the remaining one-third of seeds were kept uninoculated. The number and dry weight of nodules/plant, plant height, root length, number of main branches/plant, number of pods/plant, pod length, 1000-seed weight, seed and stover yields, and seed protein content of the crop increased significantly due to inoculation of the seeds with Rhizobium strains. Among the varieties, BARI Mung-4 performed the best in all aspects showing the highest seed yield of 1135 kg/ha. Rhizobium strain TAL169 did better than TAL441 in most of the studied parameters. The number of pods/plant and 1000-seed weight had positive correlations with seed yield/ha. It was concluded that BARI Mung-4 in combination with TAL169 performed the best in nodulation, plant growth, seed and stover yields, and seed protein content.
