1. Kishan always adopts the process of mixed cultivation for getting a higher yield of a crop. However, he always needs to keep adding more fertilizers in this method. Can you guess why?

Answer:
Kishan needs to keep adding more fertilizers because mixed cultivation involves growing different crops together in the same field. While this method can lead to higher overall yields, it also means that a variety of nutrients are drawn from the soil by the different crops. This faster and more diverse uptake of nutrients can deplete the soil more quickly than single-crop farming. As a result, to maintain soil fertility and support healthy plant growth, additional fertilizers must be added regularly to replenish the lost nutrients.

2. Which irrigation method would you recommend for fields in a region that has lot of water shortage? What is the reason for your suggestion?

Answer: For a region with significant water shortage, I would recommend drip irrigation.
The reason for this suggestion is that drip irrigation delivers water directly to the base of each plant through a network of pipes and emitters. This method minimizes water loss due to evaporation, runoff, or deep percolation, ensuring that water is used very efficiently. As a result, drip irrigation can save a substantial amount of water while still providing crops with the moisture they need to grow.
