Question

a scientist designs an experiment to test the effect of fertilizer on the height of sugar cane. two fields are fertilized and two other fields are not. what is the control group in this experiment?

Answer 1

An experiment is created by a scientist to determine how fertiliser affects sugar cane height. Two fields receive fertilization, but the remaining two do not. Fertilizer Application serves as the experiment's control group.

Fertilizer Application is typically limited to irrigated plantations and varies by region and even by farmer. Fertilizers will work best if used between 12 and 24 months before and after the peak growing season. One year after planting, farmers typically spray 50 kg of urea and 50-100 kg of DAP per acre. Since Casuarina manufactures its own nitrogen with the aid of the bacterium Frankia, it does not require a significant amount of nitrogen fertiliser. In order to prevent this, it is advised to apply 11 kg of urea and 94 kg of superphosphate at moderate level.
