Abstract: The present study was conducted to know the relationship of soil properties, with different fractions of nitrogen under maize-wheat cropping sequence. The highest coefficient of correlation of pH was with UHN(r= -0.539) and lowest with HSN (r= -0.058). Available nitrogen was exhibited positive and significant correlation with thetotal hydrolysable-N (r= 0.866**), unidentified hydrolysable-N (r= 0.848**), amino acid-N (r= 0.835**), total soil N (r= 0.830**) and nitrate-N (r= 0.781**).In case of total N,K, S, Zn and Cu uptake, correlation was highest with unidentified hydrolysable-N (r= 0.931**), (r= 0.908**), (r= 0.899**) (r= 0.880**) and (r= 0.950**), respectively followed by total hydrolysable-N (r= 0.929**), (r= 0.907**), (r= 0.856**), (r= 0.866**) and (r= 0.948**), respectively. Grain yield of maize was correlated highest with unidentified hydrolysable-N (r= 0.950**) followed by total hydrolysable-N(r= 0.948**).
