Maize grown with conservation agriculture and optimal nitrogen management practices showed higher productivity and profitability. Specifically, using zero tillage on raised beds with crop residue resulted in the best outcomes, with increased plant height, grain yield, and nutrient uptake. This approach also reduced cultivation costs and increased net returns compared to conventional tillage methods. Additionally, applying 120 kg of nitrogen per hectare led to the highest yields, but the most cost-effective nitrogen dose for optimal maize production was found to be 142 kg per hectare. In conclusion, adopting conservation agriculture practices like zero tillage on raised beds with crop residue, along with proper nitrogen management, can significantly improve maize productivity and profitability.
