The correct answer is Tea.
Tea is a particularly sensitive crop to acidic soils. The optimum pH for tea cultivation is 5.5-6.5. If the soil pH is below 5.5, the tea plant will not be able to absorb essential nutrients, such as nitrogen and phosphorus. This can lead to stunted growth, poor yields, and a decrease in the quality of the tea leaves.
Maize, rice, and wheat are all less sensitive to acidic soils than tea. However, if the soil pH is too low, these crops may also experience some growth problems.
In addition to pH, other factors that can affect the growth of tea plants include soil fertility, temperature, and rainfall. Tea plants prefer well-drained, loamy soils that are rich in organic matter. They also require a warm, humid climate with an average annual rainfall of 1,500-2,000 mm.
If you are growing tea in Manipur, it is important to test the soil pH and take steps to adjust it if necessary. You should also make sure that the soil is well-drained and that the tea plants are getting enough water.
