The field experiment was conducted at R.B.S. College, Bichpuri, Agra to evaluate the effect of nutrient
management on soil properties in Inceptisols of Agra. The experiment was layout in randomized block
design with ten treatments of T1- 100% RDF 80:40:40, T2- 100% RDF + S 20kg/ha + FYM 5t/ha, T3- 100 % RDF
+ Zn 5kg/ha + FYM 5t/ha, T4 - 100% RDF + S 20kg/ha +Zn 5kg/ha + FYM 5t/ha, T5- 75 % RDF + S 20kg/ha + FYM
5t/ha, T6- 75 % RDF + Zn 5kg/ha + FYM 5t/ha, T7- 75 % RDF + S 20kg/ha + Zn 5kg/ha + FYM 5t/ha, T8- 50 % RDF
+ S 20kg/ha + FYM 5t/ha, T9- 50 % RDF + Zn 5kg/ha + FYM 5t/ha, T10- 50 % RDF + S 20kg/ha + Zn 5kg/ha + FYM
5t/h, with three replications. The study found that applying (T4) @ 100% RDF + S 20kg/ha +Zn 5kg/ha + FYM
5t/ha-1 significantly improved soil organic carbon, available nutrients (N, P, K, S and Zn) compared to other
treatments. Application of (T4) @ 100% RDF + S 20kg/ha +Zn 5kg/ha + FYM 5t/ha-1 recorded significantly
higher EC, pH, soil organic C, available nitrogen, phosphorus, potassium, sulphur and zinc over (T9) @ 50 %
RDF + Zn 5kg/ha + FYM 5t/ha treatment.
