Abstract

To study the influence of Rhizobium inoculation on nodules, growth and yield of French beans (Phaseolus vulgaris L.) cultivars, an experiment was conducted at National Tea and High value crops research Institute (NTHRI) Shinkiari, Mansehra during 2016. Seeds of three different cultivars of French bean i.e ‘Evergreen’, ‘Komal green’ and ‘Winner’ were inoculated with Rhizobium in main plot; whereas cultivars kept in sub plots in order to evaluate various growth parameter and yield. The Rhizobium inoculation significantly enhanced the growth and yield parameter of French beans cultivars. Maximum germination percentage (90.01%), plant height (29.55 cm), plant spread (27.55 cm), number of nodules (27.22 plant-1), number of branches (6.38 plant-1 ), number of pods (41.83 plant-1), pods length (20 cm) and yield (5939.4 kg ha-1) was observed in synthetic Rhizobium inoculated seeds. Evergreen cultivars of French beans showed best result i.e. maximum germination percentage (89.48), plant height (28.83cm), plant spread (25.83 cm), pods length (18.95 cm) l, number of branches (6.38 plant-1), number of pods (40.80 plant-1), number of nodules (25.00 plant-1) and yield (5810.8 kg ha-1). All the parameter of growth and yield showing best result for synthetic Rhizobium inoculation of seeds while among the cultivar ‘Evergreen’ is best for cultivation.
