A field study was conducted at Zonal Agricultural and Horticultural ResearchStation (ZAHRS), Babbur farm, Hiriyur to study “Effect of hydrogel on soil properties ingroundnut (ArachishypogaeaL.) in Central dry zone of Karnataka” with an objective to study the effect of hydrogel on soil physical properties. The results revealed that the treatment with an application of RDF + hydrogel @ 4 kg ha-1and FYM @ 10 t ha-1recorded the higher soil porosity (48.64 %), MWHC (25.27 %), higher field capacity of the soil (15.56 %), lowest PWP (2.13 %) and higher available water content (13.43 %). The treatment with RDF + 3.0 kg hydrogel ha-1 + 10 tons FYM ha -1 and RDF + 2.0 kg hydrogel ha -1 + 10 tons FYM ha -1 were found on par with the above said treatment. Thus, the moisture stress, which is limiting the yield in groundnut production, could be overcome by the combined application of RDF, FYM @ 10 t ha-1and hydrogel @ 4.0 kg ha-1.
