Different combinations of fertilizers were tested on potatoes to see how they affected yield, plant traits, and soil health. The best results came from using 1500kg/hm2 slow release fertilizer with 15,000kg/hm2 organic manure, which increased potato yield the most. This combination also improved plant height, stem diameter, potato quality, and chlorophyll content. The content of important nutrients like nitrogen, phosphorus, and potassium in the potatoes also increased significantly. Overall, using special potato fertilizer along with organic manure can boost nutrient levels in the soil and enhance soil fertility.
