EFFECT OF BIOFERTILIZER, FARM-YARD MANURE AND VERMICOMPOST ON GROWTH AND YIELD OF LENTIL

Abstract

The experiment was conducted at the Sher-e-Bangla Agricultural University, Dhaka- 1207, Bangladesh, from November 2021 to March 2022 to study the effect of biofertilizer, farm-yard manure, and vermicompost on the growth and yield of BARI Mosur-6. The experiment comprised of single factor eight treatments viz. T = Control, T 1 = Seed inoculation with Rhizobium, T = Seed inoculation with Azospirillum + PSB (Phosphate solubilizing bacteria) + KMB (Potassium mobilizing bacteria), T 2 = RDF (Recommended dose of fertilizer), T = Seed inoculation with Rhizobium + Azospirillum + PSB + KMB, T 5 4 = RDF + Vermicompost, T ii

6 0 = RDF + FYM (Farm-yard manure), T = Seed inoculation with Rhizobium + Azospirillum + PSB + KMB + Vermicompost + FYM. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three (3) replications. The results revealed that treatment T (RDF + FYM) exhibited its superiority compared to other organic, inorganic fertilizers, and synthetic biofertilizers in terms of seed yield of lentil. Treatment T 6 6 showed the tallest plant (39.70 cm), the highest number of branches plant -1 (9.30), the highest number of nodules plant (27.39), the highest filled pod plant -1 (69.39), the highest number of dry weight (18.34 g), the highest amount of 1000 seed weight (26.23 g), the highest seed yield (1.95 t ha ) and treatment T 5 (RDF + Vermicompost) gave second highest seed yield (1.91 t ha ), the highest stover yield (3.57 t ha -1 ), the highest biological yield (5.52 t ha -1 3 -1 -1 -1 7 ), and the highest harvest index (38.57) in this experiment. Farm-yard manure with the recommended dose of fertilizer application seemed promising for producing a higher yield of lentil.
