Response of Knol khol (Brassica oleracea L. var. gongylodes) to different organic amendments and microbial consortium

The performance of Knol khol (Brassica Oleracea L. var. gongylodes) var. White Vienna was evaluated in different organic amendments along with microbial consortium during 2014–15 and 2015–16. There were eight treatments consisting of T₁(Microbial consortium + Rock phosphate), T₂(T₁+ 2.5 t ha⁻¹ compost), T₃(T₁+ 5 t ha⁻¹ compost), T₄(T₁+ 2.5 t ha⁻¹ Vermicompost), T₅(T₁+ 5 t ha⁻¹ Vermicompost), T₆(Enriched compost 2.5 t ha⁻¹), T₇(Enriched compost 5t ha⁻¹) and T₈ (Recommended dose of fertilizer). The highest yield of 191.45 q ha⁻¹ was recorded in conventional treatment, while among the organic treatments, T₇ (Enriched compost 5 t ha⁻¹) recorded the highest yield (169.73 q ha⁻¹) and other yield attributing parameters. The lowest yield attributing characters were exhibited by T₁ (Rock phosphate + Consortium). On quality parameters, the organic treatments exhibited superior results, when compared to inorganic treatments.
