A field experiment was conducted during rabi season of 2009-10 at Jobner to study the effect of organics and irrigation scheduling on nutrient content, uptake and properties sandy loam soil. The results showed that application (FYM 5 tha + vermicompost 2.5 tha + Rhizobium) F5 V2.5 + R gave highest NPK concentration in both seed and straw and their total uptake by fenugreek crop. Increasing irrigation levels from I1 Â to I3 , recorded significantly lowest nitrogen content in both seed and straw and significantly increased phosphorus and potassium concentration in seed and straw, total uptake of nitrogen, phosphorus and potassium as compared to I1 . Application of all the organics resulted in significant reduction in bulk density, EC and pH of soil, whereas improvement in organic carbon content, available nitrogen and phosphorus status of soil at harvest was registered, where addition of F5 V2.5 R+P treatment registered significantly maximum values of these soil properties over control.
