Influence of IPNM on the Economics of Cauliflower (Brassica oleracea var. botrytis L.) var. Snow Crown

The present experiment was carried out with cauliflower var. Snow Crown in randomized block design with three replications. The experiment comprised of eleven different treatment combinations of five different sources of nutrients including organic, inorganic and biofertilizers alone in combinations were applied following the proper procedure as per the treatments. The experimental findings revealed that the treatment T₁₁ (Half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha + Vesicular Arbascular Mycorrhiza @ 5 kg/ha) showed better response to plant growth and its attributes and quality. However, maximum yield 269.33 q/ha and 267.02 q/ha were obtained with the application of half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha + Vesicular Arbascular Mycorrhiza @ 5 kg/ha followed by T₉ (Half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha). On the basis of economic analysis, maximum cost: benefit ratio (3.18 and 3.05) was recorded with the application of half dose of NPK/ha + FYM @ 15 tonnes/ha + Azospirillium @ 5 kg/ha + Vesicular Arbascular Mycorrhiza @ 5 kg/ha (T₇) during 2009–10 and 2010–11, respectively and this treatment combination was found most beneficial and feasible for cultivation of cauliflower.
