Effect of integrated nutrient management on growth and yield 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 growth and yield of Yardlong bean (Vigna unguiculata ssp. sesquipedalis) cv. Arka Mangala. As regards the Gowth parameters the maximum vine length (2.61m), number of primary branches (7.60), terminal leaf length (16.57 cm), number of nodes per plant (19.37), were reported by application of 75% RDN through inorganic + biofertilizers (Rhizobium + PSB). In respect of 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 (14.26t/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). Thus growth and yield may be improved by integrated use of organic and inorganic sources of nutrients.
