A pot culture experiment was conducted in the year 2017 at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to study the impact of soil and foliar application of humic acid from vermicompost and commercial source on growth, yield and quality parameters of groundnut variety GPBD-4 by adopting completely randomized block design with thirteen treatments and three replications. The highest plant height (36.83 cm), LAI (0.96) and relative chlorophyll content (34.82) was recorded in the treatment which received soil application of humic acid from vermicompost @ 20 kg ha-1 in combination with the foliar spray of 0.2% at 30 DAS. Similar trend was observed in yield and quality parameters of groundnut. Significantly highest number of pods plant-1 (24.00), pod yield plant-1 (14.80 g plant-1), oil content (46.12%) and crude protein content (25.38%) was also recorded in the same treatment. The results revealed that there is a statistical increase in the periodical observation, yield and quality of groundnut with the additional application of humic acid extracted from vermicompost over the recommended package of practice.
