A study was done to see how adding rock phosphate to compost affects the growth of finger millet and cowpea crops. Different types of compost were enriched with rock phosphate and used in the experiment. The plants grown with enriched compost had higher levels of important nutrients compared to those grown with regular compost. The crops treated with recommended nitrogen and potassium, along with 75% of their phosphorus from enriched urban solid waste compost, grew taller and had more tillers or branches than the others. This shows that using rock phosphate enriched compost can improve the growth of finger millet and cowpea crops.
