Studies on influence of bio-fertilizers on quality and economics of cauliflower cv. PSB K-1 production

Abstract

A field experiment was carried out on cauliflower (Brassica oleracea L. var. botrytis cv. Pusa Snowball K-1) during 2006 and 2007 with objectives to know the influence of bio-fertilizers (Azotobacter, Azospirillum, AMF, PSB-1) and inorganic fertilizers (RD of NPK kg/ha) on quality and economics of cauliflower. The experiment was laid out in randomised block design consisting of 21 treatments. The results indicated that bio-fertilizers in combinations with inorganic fertilizers performed better as compared to control (FYM), recommended dose of NPK and bio-fertilizers alone. The application of PSB 1 + 50 or 75 or 100 per cent of phosphorus+ recommended dose of nitrogen and potassium performed significantly better overall other treatments including control for quality characters followed by AMF + 50 or 75 or 100 per cent of phosphorus + recommended dose of nitrogen and potassium. The inoculation of PSB 1 + 100 per cent phosphorus+ recommended dose of nitrogen and potassium recorded highest yield (33.94 t/ha) with cost benefit ratio of 1:2.58 over uninoculated control (FYM).
