Abstract :

A long term experiment was established on resource conservation technologies a sustainable approach for careful management and preservation of resources and environment. This study includes the resource conservation strategies through tillage and residue management for addressing crop productivity, energy saving and soil quality under rice & wheat cropping system. Conventional practices with and without crop residue were improved by adopted resource conservation technologies viz. reduce tillage with and without crop residue and zero tillage with and without crop residue with different irrigations practices. By using these practices it is observed that Percentage organic carbon increased from 0.62 % to 1.07 %, Available Nitrogen (N) increased from 285 to 487 kg/ha, Available Potassium (K) increased from 179 to 280 kg/ha, Available Phosphorus (P) increased from 23.4 to 36.8 kg/ha Availability of micronutrients Mn, Cu, Zn, and Fe also increased from 11.13 to 21.46 mg/kg, 0.45 to0.99 mg/kg, 0.44 to 1.11mg/kg, and from 7.26 to 21.43 mg/kg respectively. From the study it is observed that residue left in the soil increases the availability of macro and micro nutrients to the crops hence improve the soil health and yield of crops as compared to the conventional practices.
