A study in Mozambique tested different ways to help rice grow better without expensive chemical fertilizers. They tried using a mix of urea (a type of fertilizer) and animal manure (from cows and chickens) on the crops. The results showed that combining urea with manure led to the best rice yield, plant height, number of tillers, and grain weight. This means that using a mix of urea and manure is more effective than using them separately. The study suggests that using a combination of fertilizers can help farmers get good yields from their crops and is a good way to take care of the soil.
