Present field experiment was carried out during the year 2021-22 at Horticulture Research Block, Department of Horticulture, School of Agricultural Sciences, SGRR University, Dehradun, Uttarakhand to investigate the “Efficacy of organic manures on the growth and yield attributes of cabbage (Brassica oleracea L. var. capitata) under sub-tropical conditions of Uttarakhand”. The experiment was laid out in randomized block design with three replications and six treatments. The treatments comprised following levels of various organic nutrients concentrations viz. Jeevamrutham @500l/ha (T1), Vermicompost @5t/ha (T2), FYM @ 5t/ha (T3), Vermicompost @ 2.5t/ha + Jeevamrutham @ 50% (T4), Jeevamrutham @ 50% + lukewarm water @ 50% (T5) and Control (T6). Observations on various attributes of growth and yield were recorded at 30, 40, 60 DAT and at final harvest stages. The result revealed that treatment T4 (Vermicompost @2.5t/ha + Jeevamrutham @ 50%) was found to be most significant for growth attributes viz., plant height (cm), number of leaves, leaf length (cm), leaf width (cm) and yield attributes such as number of non-wrapper leaves,polar diameter of head (cm), equatorial diameter of head (cm), head weight (g), yield per plot(kg/plot) and yield per hectare (q/ha). Also, from economic point of view, Vermicompost @ 2.5t/ha + Jeevamrutham @ 50% was found to be most profitable as compared to other treatments.
