ABSTRACT: The continuous use of chemical fertilizers is leading to the contamination of soil and adversely affects the flora and fauna.  Look out for natural forms of fertilizers is unceasing.  The aim of the present investigation was to determine the influence of vermiwash and humic acid and their combinations various concentrations on the growth of Allium cepa.   Vermiwash and humic acid and combinations of vermiwash and humic acid are used as plant growth promoters in varying concentrations.   In this study, the concentration of  3:1.5 % (vermiwash: humic acid) was found to be the most effective formulation which was manifested in increase in growth, soft shoots, number of branches, total carbohydrate content and total protein content followed by a concentration of 3:2 % (vermiwash: humic acid).  This study was effective in formulating an efficient chemical free fertilizer that can be further used in agriculture on a large scale.

KEYWORDS: Humic acid, Vermiwash, Allium cepa; plant growth parameters
