Abstract: Soil test crop respo11se correlations studies conducted 11·ith 11Julberrv on sandy loam yel/mv-reddish coarse textured soil under rainfed conditio11 at Regional Sericultural Research Station Ranchi. Jharkhand provided correlatwns of high predictability be111 een biomass yield of soil available nutrients and fertilizers applied.
