The researchers studied different tillage methods and fertilizer doses to reduce energy costs in growing wheat. They found that using 50% conventional tillage with weedicide and interculture resulted in the highest wheat yield. Applying 100% nitrogen through inorganic fertilizer also led to high grain yields. The energy and cost of operations were lower with reduced tillage compared to conventional tillage. Overall, the benefit-cost ratio ranged from 1.08 to 1.41, showing that the methods used were effective in saving energy and reducing production costs for wheat cultivation in dryland conditions.
