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.

Answer:
Vacuum
Explanation:
A vacuum is usually defined as a space in which there is an absence of matter. It can also be said that there is an extremely low amount of pressure due to which the particles present in it are not affected by any type of process that occurs in space. The value of pressure is lower than the value of normal atmospheric pressure.
For example, sound cannot travel in space because there is no medium such as water and air through which the sound waves can propagate.
The correct answer for this question is:
A farmer planted legumes and cabbage in the same field that is devoid of fertilizers. The yield from this field is better than the cabbage planted inanother field without legumes. The reason for this is because (A) <span>nitrogen-fixing present in the roots of legumes aid enrichment of nitrogen in the soil.</span>
