The rotation inensity of maize - wheat + gram - moong is

Answer: Option C

Crop rotation intensity is growing the combination of crops that will match soil water storage with crop water use under the local climatic conditions in a year.
This can be calculated by counting the number of crops grown in a rotation and is multiplied by 100 and then divided by the duration of the rotation.
Here 3 crops will be counted i.e maize, moong, wheat + gram together. Therefore the rotation intensity will be 300%.
