Abstract:
The present investigation was carried out during the kharif season of 2018-19 at Horticultural Research Farm, Department of Horticulture, Pandit Deen Dayal Upadhyay Institute of Agricultural Sciences, Utlou. Experiment was laid out in Completely Randomized Design (CRD). Local seeds of winged bean collected from market were taken for the experimental trial and ten treatments were used. After selection, the seeds were sown at the spacing of 90cm x45cm. From the present investigation biofertilizer mixtures of Rhizobium, vermicompost, Vesicular Arbuscular Mycorrhiza (VAM) and Phosphate solubilizing bacteria (PSB) (T₁₀) was found significantly superior in terms of yield attributes viz., secondary branches (8.9), pod length (13.4cm), seed per pod (11.6) and pod fresh weight per plant (14.88g). Treatment consisting of Rhizobium only (T₂) gave maximum (3467.00 mg) pod dry weight, while T₈ (Rhizobium + PSB) produced maximum (17.25 ft.) plant height. Maximum weight of tuber (167.53 g) was recorded with treatment T₉ (Rhizobium+ vermicompost + VAM). Least performance in terms of growth and yield of winged bean was recorded with control treatment. Statistical analysis of variance (p=0.05) showed that use of different biofertilizers significantly increased in all growth and yield parameters of winged bean. Hence, the results suggest that biofertilizers enhance the growth and yield of winged bean which should be encouraged for future crop improvement programme.
