ABSTRACT:

The aim of the present investigation was to determine the influence of Seaweed Liquid Fertilizer (SLF), Humic acid (HA) and combinations of SLF: HA in various concentrations on the growth of Groundnut (Arachis hypogaea). The above plant growth promoters are applied as foliar spray at an interval of twice in a month with the following concentrations such as SLF (1 to 10%), HA (0.1 to 1%) and SLF:HA (1:0.9% to 9:0.1%). The SLF:HA (6:0.4%) was found to be the most effective formulation with increasing growth of shoots, number of branches, total carbohydrate content, total protein content and total chlorophyll content followed by SLF 5% and HA 0.6%. This study helps to formulate an efficient chemical free fertilizer for maximum Agriculture produce.

KEYWORDS: Growth promoters; Humic acid; Seaweed liquid fertilizer; Arachis hypogae L.
