To investigation Improving wheat (Triticum aestivum L.) and soil productivity through precision nitrogen management practices and efficient planting system was conducted during Rabi season of year 2022-23 on Agricultural Farm at Rama University, Kanpur 209217 (U.P) India. The experiment was laid out in Randomized block design (factorial) with 16 treatment combinations and replicated thrice. Four tillage practices viz. T1=Zero tillage (ZTW); T2=Reduced tillage (RT); T3=Rotavator tillage (RTW) T4=Furrow irrigated raised beds (FIRB) and Precision N management N1= Control (N0P0K0); N2= RDN (150: 75: 60 N: P2O5: K2O kg /ha); N3= Targeted yield 5.5 t/ha (170: 75: 60 N: P2O5: K2O kg /ha); N4=Leaf Colour Chart (75: 75: 60 N: P2O5: K2O kg /ha). Higher growth attributing characters at different crop stages such as plant height, number of tillers, plant dry matter and yield attributing characters such as length of spike, number of spike, number of grains per spike and test weight were associated with Precision N management N1= Conrol (N0P0K0); N2= RDN (150: 75: 60 N: P2O5:K2O kg /ha); N3= Targeted yield 5.5 t/ha (170: 75: 60 N: P2O5: K2O kg /ha); N4= Leaf Colour Chart ((75: 75: 60 N: P2O5: K2O kg /ha), as basal Similarly, Higher grain yield, straw yield and harvest index along with B:C ratio were also associated with tillage practices. All these plant growth and yield attributing characters and yield along with net monetary income & B: C ratio was observed higher in variety T4 by raised bed method followed by F3 by raised bed method.
