Effect of Nutrient Menagement on Growth, Yield and Quality of Onion (Alium cepa L.)

Abstract

A field experiment was conducted on the Horticulture Research Farm of the RBS College, Bichpuri, Agra during the rabi season of 2016-18. In this experiment eight treatments were tested with three replications in randomized block design (RBD). Treatments were (T1) recommended dose of fertilizer (RDF) (T2) 100% RDF + Azotobacter, (T3) 100% RDF + FYM, (T4) 100% RDF + Azotobacter + FYM, (T5) 80% RDF + Azotobacter + FYM, (T6) 80% RDF + FYM, (T7) 80% RDF + Azotobacter and (T8) control. The application of 100%RDF +Azotobacter + FYM (T4) significantly maximum plant height (50.14cm), maximum number of green leaves (8.65), maximum leaf length(45.53cm). maximum fresh weight of top of plant 45.34gm), maximum fresh weight of bulbs (84.32gm), maximum diameter of bulb (6.9cm) and the highest bulb yield of 33.95 t/ha. were recorded from treatment T4 (100%RDF +Azotobacter + FYM)
