Abstract:

Onion (Allium cepa L.) is an important vegetable crop grown extensively in Karnataka. A field experiment was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Raichur, Karnataka during 2014 and 2015 to study the influence of organics, inorganic fertilizers, Azospirillum and Pseudomonas fluorescens on growth parameters, yield and purple blotch disease of onion. The experiment was laid out in randomized complete block design with 10 treatments and three replications. Significantly higher values were recorded for plant height (62 cm), number of leaves (11.35), bulb diameter (8.30 cm), bulb weight (57 g) and total yield (41.8 t/ha) in the treatment consisting of 50 per cent of recommended nitrogen applied through poultry manure, 50 per cent nitrogen through inorganic fertilizers, Azospirillum and P. fluorescens but lower purple blotch severity (22 %) was recorded in the plots treated with 50 per cent recommended N through FYM + 50 per cent recommended N through inorganic fertilizers, Azospirillum and P. fluorescens. Control, recorded lower values for growth and yield parameters with higher purple blotch severity. Considering the results of this experiment, the conjunctive application of organic manure, inorganic fertilizers, Azospirillum and P. fluorescens was recommended to enhance the yield of onion.


Keywords: Azospirillum, P. fluorescens, Purple blotch, Organic and inorganic fertilizers.
