RESPONSE OF AZOTOBACTER IN CAULIFLOWER (BRASSICA OLERACEA L. VAR. BOTRYTIS) PRODUCTION AT LAMJUNG, NEPAL

Abstract

A field experiment was carried out at research field of Lamjung Campus, Nepal during September 2015 to February 2016 to assess the response of cauliflower (Brassica oleracea L. var. botrytis) to different combination of nitrogenous fertilizer with Azotobacter. 6 treatment with 4 replications were laid out in Randomized Complete Block Design. Phosphorous and potassium was applied full does in all the treatments with chemical fertilizer. It was recorded that the application of recommended doses of nitrogen along with the bio-fertilizer significantly increased morphological characters and yield as compared to other treatments. Besides, the stem diameter was non-significant to the different treatments. It was followed by the full dose of NPK without azotobacter and then 50% nitrogen with azotobacter, which was statistically at par with 25% nitrogen with azotobacter, followed by FYM + Azotobacter. Curd yield along with all the morphological characters were seen lowest in control. Cauliflower curd yield at recommended dose of nitrogen did not significantly differ with the curd yield recorded at half of recommended dose of nitrogen with azotobacter. The finding demonstrated a saving of 50% of nitrogen where it can be substituted with the application of bio-fertilizer to increase the yield and morphological character.
