Effect of integrated nutrient management on yield and quality of yardlong bean (Vigna unguiculata (L.) Walp. Ssp. Sesquipedalis Verdc.)

Abstract

The present investigation was carried out during Rabi season of 2018-19 to evaluate the effect of various sources of nutrients including organic, inorganic and biofertilizers on yield and quality of yardlong bean (Vigna unguiculata ssp. sesquipedalis) cv. Arka Mangala. As regards the yield per hectare and over all yield contributing factors, such as number of cluster per plant (48.30), pods per cluster (3.93), pod length (62.08 cm), pod girth (24.87 cm), pod yield per plant (263.70 g), total yield (14.26 t/ha) and seeds per pod (15.06) recorded significantly higher in the treatment of 75% RDN through inorganic + 25% RDN through vermicompost + biofertilizers (Rhizobium + PSB). In respect of quality parameters, such as protein content (29.76 g/100g), ascorbic acid content (19.44 mg/100g), total sugars (7.92%), reducing sugars (4.94%) recorded significantly higher in the treatment of 75% RDN through inorganic + 25% RDN through vermicompost + biofertilizers (Rhizobium + PSB).
