Abstract
A field experiment was conducted during rabi season of 2020-21 at research farm R.B.S. College, Bichpuri, Agra (U.P) to study the “effects of Vermicompost and PSB on the vegetative growth and yield of onion (Allium cepa L.)”. In this experiment 7 treatment were applied with three replications and laid out in randomized block design (RBD). Treatments were (T1) 100% recommended dose of fertilizer (NPK) (Control), (T2) 80% RDF + Phosphate Solubilizeing Bactira (PSB) (5kg/ha.), (T3) 80% RDF + VC, (T4) 80% RDF+VC + PSB (5kg/ha.), (T5) 100 %RDF + PSB (5kg/ha.), (T6) 100% RDF + VC (5kg/ha.) and (T7) 100% RDF + VC + PSB (5kg/ha.). On the basis of experiment conducted that the treatment T7 i.c, application 100% RDF+VC+ PSB (5kg/ha.) was found superior among the treatments for growth and yield of onion, the maximum bulb yield (332.64 q/ha) was obtained by application of treatment T7 100% RDF+VC+ PSB (5kg/ha.).
