A field experiment was performed to study the effects of integrated nutrient management (INM) and soil till with assorted raised seedbeds in a wheat-maize cultivation system for two years (2019-2021) in Pedocals soil. Tillage implements were kept as the main factor; Mould board (M.B) plough + cultivator + rotavator (T2), and rotavator sole (T3) were compared with cultivator + rotavator (T1) as control treatment. The assorted raised seedbeds were kept as the second main factor; no seedbed height (P1), 0.1 m high seedbed (P2), and 0.2 m high seedbed (P3). The sub-factor was INM with four levels, including compost (C2), urea (50%) + compost (50%), blend (C3), and urea (C4) as well as control i.e., no fertilizers (C1) in RCB design. The experiment’s outcomes were: T2 resulted in lower soil bulk density (1.30-1.38 g/cm3), soil strengths (208-291 N/cm2) and higher soil moisture content (15.9%). P1 provided optimum soil strengths (239-328 N/cm2). C2 reduced the soil bulk density (1.39-1.48 g/cm3) and soil strengths (229-314 N/cm2) with the highest soil moisture content (15.94%). Deep tillage decreases soil bulk density and strength which leads to better plant growth. Compost incorporation increases the water and nutrient-holding capacity of the soil. It is concluded that M.B. plough + cultivator + rotavator as tillage implements and compost incorporation were found effective in enhancing soil environment and eco-system with an average yield of 9.1 and 4.1 T/ha of wheat and maize respectively. Enhancing soil traits, deep tillage and compost incorporation have a significant role but the effect of the dimension of the raised seed bed and its interaction with tillage and INM is not specified for optimum soil traits. Therefore, their effect should be found on soil traits.
