A study looked at how different types of fertilizers affect the yield of maize and mustard crops. They found that using a mix of organic and inorganic fertilizers gave the best results for mustard seeds. The highest maize yield came from using NPK fertilizer with zinc sulfate. The combination of organic and inorganic fertilizers also helped the crops absorb more nutrients like nitrogen, phosphorus, and potassium. Overall, adding organic material like farmyard manure improved the soil's organic carbon and nitrogen levels, leading to better crop yields.
