The result revealed that application of N,P,K nutrients for a soil test crop response (STCR) targeted yield of 50 q ha"' through 50 % inorganic + 50 % organics recorded a highest gr^in yield of (3638.9 kg ha"') and straw yield of (5740.6 kg ha"'). Similarly application of N,P,K nutrients through 50 % inorganic + 50 % organics for a targeted yield of 60 q ha"' recorded highest N, K, S, Ca, Mg content in the soil. However, available P status was highest where STCR target of 50 q ha"' was fixed by application of 50 % inorganic+ 50% organics sources of nutrients. Higher values of N, P, Ca, S uptake by ragi grains and straw was noticed with 50 % inorganic + 50 % organic sources of nutrient application for a targeted yield of 50qha"' except Mg K, uptake by ragi grains and straw which has recorded higher values due to application of N, P, K nutrient through 50% inorganic 50% organic sources of nutrients for a targeted yield of 60 q ha"'. , However, the NUE was highest where nutrients were applied as per POP followed by nutrienti applied for a targeted yield of 50 q ha "' through conjunctive use of Organic and inorganic sources of nutrients. This higher NUE by ragi crop as per package clearly indicates that nutrients were applied in a well balanced manner but still STCR approach was better for achieving the higher yieldsennullThesis
