The researchers studied different ways of growing wheat after maize to see how it affects growth, yield, and profits. They tested different tillage methods and nitrogen levels. They found that using zero tillage with crop residue and applying 120 kg of nitrogen per hectare gave the best results. This method increased grain and straw yields, reduced costs, and improved profits compared to traditional tillage methods. Overall, using zero tillage with crop residue and the right amount of nitrogen can make wheat farming more profitable and sustainable.
